iv v FOREWORD PERSPECTIVE

As with many worthwhile projects, this manual was a long time in the For generations, ranchers have relied on intuition and experience to making. The dual challenge to the manual’s authors was to be technically assess the state and health of their grasslands. A detailed scientific correct and user friendly. It is our intention that ranchers and tenure assessment was rarely undertaken, as it was deemed to be an expensive, holders will recognize and adopt this monitoring process as a useful time consuming process that the rancher would be unable to complete mechanism for improving stewardship, promoting productivity, and without the aid of off-farm consultants. This manual breaks down those enhancing the viability of their ranching business. I also hope that this barriers, allowing the rancher to independently commence a widely monitoring tool will provide ranchers with information and skills that recognized scientifically based assessment that does not consume a empower them to engage in dialogue and decision-making on an equal rancher’s scarce resources of time and money. This process will also basis with government, to the benefit of both the environment and deepen the rancher’s understanding of the ecological processes that cattle. The manual is one more tool that enables ranch mangers to be affect and alter the health of grasslands. In today’s ever changing world, proactive and adaptive in their management, with information provided this manual offers the ranching community a tool to better assess and by the land itself. Such feedback is vital for ranchers to achieve their tend the state of their precious resource – the grasslands. inherent long-term interests in the health of their grazing lands. Darren Dempsey The Grasslands Conservation Council of British Columbia also intends Rancher, Frolek Cattle Co. Ltd. that the monitoring manual will be integrated into range schools throughout BC. It is important to note that the range school was born from a vision based on history and lessons learned: that ranchers and government can work together as stewards of the land. If in years to Monitoring is an important part of any range management system. The come we attain significant uptake of the manual, with the results of Ministry of Forests and Range is a proud partner in the development monitoring informing ranchers and facilitating constructive dialogue on of the Grassland Monitoring Manual for British Columbia and supports grassland management, then we will have achieved success! this methodology. The Manual is a significant contribution to grassland As the Grassland Monitoring Manual becomes more widely adopted monitoring in BC, providing ranchers with a practical tool for managing within various regions of the province, it is my hope that the purpose of their grasslands. this tool is kept at the forefront: Let’s keep working ranches working and David Borth let’s preserve the ecological integrity of our grassland ecosystems.

vi vii INTRODUCTION The Grasslands of British Columbia Consider the grassland that you are managing—it is a rare landscape in British Columbia. Our grasslands, though small and scarce, are significant. They provide important forage for the ranching industry as well as habitat for a wide variety of plants and animals. More than 30% of BC’s Species at Risk depend on Grasslands occupy grasslands for their survival. less than 1% of the Most of the province’s grasslands are found in central and southern province’s total area, BC.

2 Introduction Chapter 1 3 Ecology of Grasslands Grasslands are an important resource to the cattle industry. As you plan for and manage your grassland, you want to make the best use of the resource while maintaining the ecological integrity of your grassland. Grassland ecosystems encompass certain attributes and perform certain functions, including: • productivity • site stability • water capture, storage, and release • nutrient cycling • species diversity Maintaining these basic attributes and functions will ensure that the integrity of the ecosystem is maintained over time. The table below summarizes the importance of these attributes and functions.

tool, this manual helps you detect any problems that may occur. Addressing these problems at an early stage helps you manage your grasslands with due diligence and assists you in maintaining healthy, productive grasslands. This manual provides a strong systematic approach for recording what is happening on your grassland—both the changes you currently see on the land base, and the changes you might expect based on your management practices. A healthy, productive grassland will yield better returns to your operation.

Due diligence is an important concept in grassland management. When you are diligent, you are managing responsibly and sustainably. This monitoring tool provides a framework for due diligence. Consistent monitoring, recording, and reporting are important components in managing your grassland resource and enable you to anticipate and address problems that may arise.

Grassland Assessment Procedure Only the basics of grassland ecology are needed to use the procedures in this manual. Originally developed with the help of ranchers, this manual is a practical tool for assessing grassland status and monitoring trends over time. Training is an essential This manual is designed to be practical and easy to use. During the first step for all first time initial visual assessment of your site, five questions will be answered users of this manual. and three photos taken. The site is then revisited periodically over Training will ensure the the years in order to monitor trends. appropriate application The overview presented in this section discusses the following of this tool and it will questions: assist you in selecting • What type of grassland do I have? monitoring sites, using • What is Reference Condition? the booklets and score • How is grassland status assessed? sheets, and will assist • What are grassland indicators? you in interpreting your • What is a threshold? results. See Appendix for details. • When should I monitor? • How long does it take? • How do I select a monitoring site? • What equipment do I need? Later in the manual, Chapter 5 will detail a step-by-step procedure on how to complete your assessment once you have identified your grassland community and selected a monitoring site.

What type of grassland do I have? Chapter 3 will help you determine your grassland community. There you will find regional maps and brief descriptions of the major grassland communities found across the Central and Southern Interior of British Columbia. From the maps, you will be able to identify the grassland communities most applicable to your ranching operation. Once you have determined your grassland community, Chapters 4 through 7 will take you through the procedure to assess the status of your grasslands.

Chapter 2 7 What is Reference Condition? Trends in Grassland Status Reference Condition, essential to the assessment of grassland status, is the condition of a grassland when little or no disturbance has occurred. It reflects the influence of climate, soils, and topography on a combination of grassland indicators (see “What are Grassland Indicators?” on page 10). As you assess your grassland, you will be comparing your site to the Reference Condition. For each region, Reference Condition descriptions were developed by collecting information from a number of exclosures, lightly Reference Condition Reference Condition grazed sites, and minimally disturbed sites that shared similar site is the combination potential. The Reference Condition approximates the state of your of biological and grassland plant community had it not been grazed or disturbed. By physical factors used comparing the Reference Condition to the actual condition of your as the “reference” for grassland, you will be able to score and assess the status of your site. The plant community will be rated as: comparison with a grassland community. • Reference Condition (not altered) The Reference Condition • Slightly Altered does not represent • Moderately Altered a single site, but is • Greatly Altered based on observations from numerous sites How is grassland status assessed? to capture the range Grassland status is the state of your grassland at a particular point of variability within in time. It is measured relative to the Reference Condition by a native grassland visually estimating and scoring the five key indicators discussed next. The present condition of each indicator is measured, and community. the information collected from all indicators provides an overall assessment of the site’s status. TREND These same indicators can be used to assess a trend in grassland status change, provided that repeated observations are taken on the same site at the same time of the year, using the same procedures. Interpreting grassland status and trend is based on the collective assessment and score of all indicators combined. Changes in the indicators over time may suggest a trend, either for a specific indicator, such as plant community composition, or as a total ecosystem score based on all indicators. The most important indicator of change is a decline in cover of the dominant bunchgrasses and an associated increase in the Greatly Altered cover of small grasses, forbs, and sometimes shrubs. Low-growing bunchgrasses and forbs, such as Sandberg’s bluegrass and pussytoes, are often more abundant as disturbance increases.

Key Bunchgrasses Found in BC’s Grasslands Grassland status is measured by visually estimating and scoring five key indicators, each of which describes a specific ecological attribute or function. Assess the status of your grassland by answering the following five questions based on the indicators: 1 Plant Community Composition What is the cover of bunchgrasses? 2 Plant Community Structure Do you have the expected plant layers? Tuning your Eye — 3 Nutrient and Hydrological Cycling The monitoring tool How much litter and/or biological crust do you have on site? will assist you to “tune 4 Site Stability your eye” to identify key Is there existing or potential erosion on site? grassland indicators and 5 Invasive Plants Bluebunch Wheatgrass thus will help you collect Are invasive plants a problem on this site? reliable and consistent The questions will assist you in visually estimating and scoring each grassland information indicator. Although each indicator individually provides important which is essential for information, it is their cumulative score that will determine the any range management status of your grassland. You need to interpret this information program. relative to your management objectives and your current management practices on site.

1. Plant Community Composition: What is the cover of bunchgrasses? Plant species composition affects both the structure and productivity of grasslands, and is one of the most important indicators of grassland status. Large bunchgrasses are the principal species dominating sites in Reference Condition on all grasslands Rough Fescue in southern BC, and they account for more than 60% of the ground cover and 80% of the forage produced. Plant composition responds to significant disturbances such as continuous heavy grazing, frequent fire, prolonged periods of drought, above-normal precipitation, invasion by non-native species, or excessive recreational use. These changes are most predictable for plant species grazed by cattle. The large, perennial species most palatable to cattle, such as bluebunch wheatgrass, often decline with continuous heavy grazing.

In addition, high levels of Threshold and Transition from One Status to the Next fine particles can negatively affect water quality when they enter the fish-spawning habitats of adjoining streams and rivers. Poor management of upland grassland environments can accelerate erosion and thus impact site stability and water quality. Good management strives to prevent this situation.

16 How to Use This Manual Chapter 2 17 Assessing Grassland Status The status of your grassland at a particular time relative to the Reference Condition is determined by a visual estimate attained by scoring the five indicators outlined on page 10.

Reference Condition Reference Condition: Status Value 76–100% The site surveyed is essentially the same as the Reference Condition. The composition of the plant community, community structure, soil integrity, nutrient cycling, and hydrological process are effectively stable. Productivity will be relatively stable compared to other altered conditions. Susceptibility to weed invasion is low.

Slightly Altered Slightly Altered: Status Value 51–75% At least two of the five indicators evaluated have been rated below the Reference Condition. Changes in plant community composition, plant community structure, and litter weight are the most likely reasons for the difference between the present site and the Reference Condition. Total production and site stability, as well as susceptibility to weed invasion, are likely similar to the Reference Condition.

Moderately Altered Moderately Altered: Status Value 26–50% At least three of the five indicators evaluated have been rated below Reference Condition. Most likely, the cover of the dominant bunchgrasses is much lower than the Reference Condition, and at least two structural layers have been altered. In addition, litter weight and distribution are probably insufficient to adequately protect the soil surface. Bare soil may be increasing, and soil erosion is more likely than in the Reference Condition. These sites are generally more susceptible to weed invasion. Productivity can vary depending upon species composition and annual weather patterns.

Greatly Altered Greatly Altered: Status Value 0–25% At least four of the five indicators evaluated have been rated below the Reference Condition. Species composition and plant community structure are significantly altered. If the dominant bunchgrasses remain, they contribute very little to ground cover and provide little forage for livestock and wildlife. Generally, the dominant species have been eliminated and replaced by low-growing, shallow-rooted, unpalatable native species; or by invasive plants of low forage value. Deep-rooted shrubs may have been established in dense, persistent stands. Litter weight and distribution are usually insufficient to protect the soil against wind and water erosion, and evaporation losses are high. Active erosion is often evident. These sites are susceptible to weed invasion, and invasive plants may be the dominant species on some sites. Productivity is usually lower than the Reference Condition and, throughout the years, can be highly variable depending on species composition and annual weather patterns.

GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA IDENTIFYING YOUR GRASSLAND COMMUNITY

Before going into the field to start your assessment, you need to identify the grassland plant community you are managing. The site’s dominant species will dictate how you assess your grassland and will affect the interpretation of your results.

Each grassland community is described in a separate booklet accompanied by details describing how they are to be assessed and scored. Identifying your grassland community is a three step process:

Step1 Select your region on the BC map • See the map on page 25, Grassland Regions of Southern British Columbia • Five regions are discussed in this manual: 1 Thompson–Nicola Region 2 Okanagan–Similkameen Region 3 Boundary Region 4 East Kootenay Region 5 Cariboo–Chilcotin Region The Peace River and northern grasslands are not included in this version of the manual.

Step 2 Identify your grassland community(s) Select the fold-out map of your region that shows grassland community delineations. Here you will be able to identify the grassland communities relevant to your operation. In most cases, you will not have more than two grassland communities. A total of seven grassland communities are identified: • Big Sagebrush, Bluebunch Wheatgrass Grasslands (Lower Grassland) • Antelope-brush, Bluebunch Wheatgrass Grasslands (Lower Grassland) • Bluebunch Wheatgrass Grasslands (Middle Grassland) • Rough Fescue Grasslands (Upper Grassland) • Rough Fescue, Antelope-brush Grasslands (Upper Grassland) • Porcupinegrass, Bluebunch Wheatgrass and Spreading Needlegrass Grasslands (Upper Grassland)

It should represent the reference plant community that you wish to monitor and be representative of a management regime/grazing unit. The most important aspect of monitoring is to be consistent with where, how and when you monitor. Repeat your assessment at the same location and at the same time of year. If you have a rotational grazing system, be sure to assess your site before grazing rather than after grazing as this may influence your results. Always be consistent.

Variability should not be a problem, however, determining the dominant vegetation type may be more difficult. Use the dominant plant community in an adjacent or similar pasture (one that has a similar aspect, slope, soil, etc.), to help you determine the plant community. If you are unable to easily determine the grassland community, request assistance from an agrologist. Remember, this is a learning process. Once the dominant vegetation type is determined, proceed to the assessment process. As with a larger pasture, your monitoring site should be clearly marked. If a fence delineates your monitoring site, mark a post for future reference or use a metal peg pounded into the ground. If possible, all monitoring sites should be identified and recorded with a GPS. This will assist greatly in finding your peg or post in future years.

Typical Big Sagebrush, Bluebunch Wheatgrass grassland community. PHOTO BRIAN WIKEEM This grassland community is dominated by bluebunch wheatgrass. On north-facing slopes, this species may be mixed with rough fescue. On relatively cooler, moister sites, Idaho fescue and rough fescue will occasionally co-dominate with bluebunch wheatgrass. Note that Idaho fescue may become the dominant bunchgrass on some sites, particularly in the Similkameen and Okanagan valleys. Big sagebrush and other shrubs, such as threetip sagebrush and common rabbit-brush, account for less than 20% of the plant cover. Biological crusts are widespread and perform an important ecological function.

Although very similar to the Sagebrush, Bluebunch Wheatgrass grasslands, the Antelope-brush, Bluebunch Wheatgrass community has some differences. Antelope-brush, Bluebunch Wheatgrass grasslands are mainly found in the very hot, dry Bunchgrass and Ponderosa Pine biogeoclimatic zones in the South Okanagan—Similkameen region and to a very limited extent in the East Kootenay region. Antelope-brush and common rabbit-brush are the most common shrubs on the driest sites in the South Okanagan. Big sagebrush replaces antelope-brush in slightly moister and cooler conditions. Antelope-brush and other shrubs account for less than 20% of the plant cover. Biological Biological crusts play a critical ecological role by assisting in moisture retention, fixing crusts (mosses, lichens, and algae) are widespread and perform atmospheric nitrogen, and ensuring soil stability. In Lower Grasslands, biological an important ecological function, particularly in dry, semi-desert crust cover increases significantly where bunchgrass plants are more widely spaced conditions where the spaces between bunchgrasses are significant. and where litter cover is lower. Biological crusts may increase where site disturbance causes a reduction in bunchgrass and other plant cover, as well as a reduction in litter.

GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA Bluebunch Wheatgrass Grasslands

Bluebunch Wheatgrass grasslands are common throughout the Southern Interior at mid elevations from 600 m to 900 m, and are found throughout the Okanagan–Similkameen, Thompson–Nicola, Boundary, Cariboo–Chilcotin, and East Kootenay regions. Bluebunch Wheatgrass grasslands are mainly found in the Bunchgrass, Ponderosa Pine, and Interior Training is an essential Douglas-fir biogeoclimatic zones, but are sometimes first step for all first time found in the Montane Spruce and Engelmann Spruce– users of this manual. Sub-alpine Fir zones. Training will ensure the Bluebunch wheatgrass dominates this grassland community. Rough appropriate application fescue may be mixed with bluebunch wheatgrass. On relatively of this tool and it will cooler, moister sites, Idaho fescue and rough fescue will occasionally assist you in selecting co-dominate with bluebunch wheatgrass. Note that Idaho fescue monitoring sites, using may become the dominant bunchgrass on some sites, particularly in the booklets and score the Similkameen and Okanagan valleys. sheets, and will assist This grassland typically has five structural layers, including a limited you in interpreting your shrub layer, tall grasses and forbs, medium grasses and forbs, low results. See Appendix for grasses and forbs not exceeding 5 cm, and biological crusts (mosses, details. lichens, and algae). Biological crusts are not as abundant in this grassland community as they are in the Lower Grasslands (Big Sagebrush, Bluebunch Wheatgrass and Antelope-Brush Bluebunch Wheatgrass communities), but still perform an important ecological role.

Big sagebrush, common rabbit-brush and other shrubs in Bluebunch Wheatgrass Biological crusts play a critical ecological role by assisting in moisture retention, fixing grasslands account for less than 5% of the plant cover. When the shrub layer increases atmospheric nitrogen, and ensuring soil stability. In Middle and Upper grasslands, significantly in this community, this possibly indicates extended fire suppression, biological crust cover often decreases significantly where bunchgrass plants are more overgrazing or other disturbance. PHOTO RICHARD DOUCETTE tightly spaced and where litter cover is higher. Conversely, biological crusts may increase where increased site disturbance causes a reduction in bunchgrass and other plant cover, as well as a reduction in litter. This trend may serve as an early warning or indicator of over-grazing by wildlife or livestock. PHOTO BRIAN WIKEEM

PHOTO Accounts for 24% BRIAN WIKEEM of total score Litter is an important indicator of nutrient cycling and hydrological function. Litter on the soil surface helps intercept rainfall, slow water movement across the soil surface, promote infiltration into the soil, and regulate heat on the soil surface. Litter includes residual plant cover from previous year’s growth (dead plant material) and may be found standing next to current growth, or on the ground. Material on the ground may be freshly fallen material or material that is partially broken down. When collecting litter, collect all litter found within your plot.

What to expect on your site in the Reference Condition: • Bunchgrasses dominate the site. • Litter cover is uniform on the site. Biological crusts play an important role in moisture • Litter matter consists of dead plant material on the soil surface retention and soil stability. and within plants. PHOTO BRIAN WIKEEM • Litter weight is greater than 1000 kg/ha. Litter weight may vary from 1000–2000 kg/ha. • Litter covers 75% or more of the ground surface. • Stable soils with limited bare soil and soil disturbance, where erosion features and/or bare soil accounts for less than 10% of the ground surface or site.

Scoring in this section is divided into two components: • Assessing litter weight • Assessing the cover of litter and biological crusts Both litter and biological crusts are measured together. An increase in litter weight and cover over the site often results in a decrease in crust cover—there is less open space for the crusts to establish.

The Importance of Litter Step 1 Litter is the key indicator Hand rake and assess litter of nutrient cycling and hydrological function. Litter Litter weight is estimated by hand-raking litter from a 0.25 m2 area on the soil surface helps or within a plot frame. The litter will be either weighed or compared intercept rainfall, slow to the photographs on page 19. water movement across the soil surface, and promote Collect three to five samples from representative areas on the site. infiltration into the soil.

It slows down soil heating and helps If you installed transects, hand-rake litter from a 0.25 m2 area or plot the soil to cool more quickly, every 3 to 5 m along the transect. reducing moisture loss.

GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA Rough Fescue Grasslands

Rough Fescue grasslands are common throughout the Southern Interior at mid to high elevations from 900 m to 1200 m and are found throughout the Okanagan– Similkameen, Thompson–Nicola, Boundary, and East Kootenay regions. Rough Fescue grasslands are mainly found in the Interior Douglas-fir biogeoclimatic zones with some Training is an essential limited occurrences in the Bunchgrass and Ponderosa first step for all first time Pine zones. users of this manual. This grassland community is dominated by rough fescue. Bluebunch Training will ensure the wheatgrass may be mixed with rough fescue on south-facing slopes appropriate application or on drier sites. On relatively drier sites, bluebunch wheatgrass of this tool and it will will co-dominate with rough fescue. Note that Idaho fescue may assist you in selecting become the dominant bunchgrass on some sites, particularly in the monitoring sites, using Similkameen and Okanagan valleys at lower elevations. the booklets and score This grassland community typically has five structural layers, sheets, and will assist including a limited shrub layer, tall grasses and forbs, medium you in interpreting your grasses and forbs, low grasses and forbs not exceeding 5 cm results. See Appendix for (including sedges and rushes), and biological crusts (mosses, details. lichens, and algae). Biological crusts are not as abundant in this grassland community as in the Lower Grasslands (Big Sagebrush, Bluebunch Wheatgrass and Antelope-brush Bluebunch Wheatgrass communities), but still perform an important ecological role.

Chapter 5 Booklet 3 1 Biological crusts play a critical ecological role by assisting in moisture retention, fixing atmospheric nitrogen, and ensuring soil stability. In Middle and Upper grasslands, biological crust cover often decreases significantly where bunchgrass plants are more tightly spaced and where litter cover is higher. Conversely, biological crusts may increase where increased site disturbance causes a reduction in bunchgrass and other plant cover, as well as a reduction in litter. This trend may serve as an early warning or indicator of over-grazing by wildlife or livestock. PHOTO BRIAN WIKEEM

GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA Rough Fescue, Antelope-brush Grasslands

Rough Fescue, Antelope-brush grasslands are only found in the East Kootenay region in the dry, mild Interior Douglas-fir biogeoclimatic zone at elevations from 750 m to 1200 m.

This grassland community is dominated by rough fescue. Bluebunch Training is an essential wheatgrass may be mixed with rough fescue on drier sites. first step for all first time Bluebunch wheatgrass will co-dominate with rough fescue on users of this manual. relatively drier sites, while Idaho fescue may become the dominant Training will ensure the bunchgrass on some sites. appropriate application Antelope-brush and other shrubs, such as Rocky Mountain juniper, of this tool and it will saskatoon, common snowberry and choke cherry are common assist you in selecting and account for less than 40% of the plant cover. Biological crusts monitoring sites, using (mosses, lichens, and algae) are less frequent in this grassland community, but still provide an important ecological role. the booklets and score sheets, and will assist This grassland community typically has five structural layers, you in interpreting your including shrubs, tall grasses and forbs, medium grasses and forbs results. See Appendix for low grasses and forbs not exceeding 5 cm, and biological crusts. details.

Chapter 5 Booklet 4 1 Antelope-brush, Bluebunch Wheatgrass grasslands are different than the Rough Biological crusts play a critical ecological role by assisting in moisture retention, fixing Fescue, Antelope-brush grasslands of the East Kootenay and are mainly found in the atmospheric nitrogen, and ensuring soil stability. In Middle and Upper grasslands, very hot and dry Bunchgrass and Ponderosa Pine biogeoclimatic zones in the South biological crust cover often decreases significantly where bunchgrass plants are more Okanagan–Similkameen, shown above. PHOTO BRIAN WIKEEM tightly spaced and where litter cover is higher. Conversely, biological crusts may increase where increased site disturbance causes a reduction in bunchgrass and other plant cover, as well as a reduction in litter. This trend may serve as an early warning or indicator of over-grazing by wildlife or livestock. PHOTO BRIAN WIKEEM

Antelope-Brush in the East Kootenay is typically smaller and less prominent than the shrub found in the South Okanagan.

Scoring in this section is divided into two components: • Assessing litter weight • Assessing the cover of litter and biological crusts on the site in crust cover—there is less open space for the crusts to establish. Both litter and biological crusts are measured together.

Short-awned porcupinegrass is more common on gentle north-facing slopes, or in slightly moister conditions such as depressions or at the eastern and northern extent of these grasslands. Conversely, bluebunch wheatgrass will become the dominant bunchgrass on steep south- facing slopes and on drier sites with coarse soils.

Biological crusts play an important ecological function. When site disturbance intensifies, bunchgrass, other plants and litter cover decrease, and may result is increased biological crusts. • Litter weight varies from 1000 kg/ha for bluebunch wheatgrass- dominated sites to greater than 2000 kg/ha for porcupinegrass- and spreading needlegrass-dominated sites. On all sites, litter cover is 75% or more of the ground surface. • Stable soils show limited bare soil and soil disturbance. Erosion features and/or bare soil account for less than 10% of the ground surface. • Invasive plants are not present or account for less than 1% cover on the site. Short-awned Porcupinegrass

PHOTO-POINT MONITORING

PHOTO MIKE DUFFY

GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA CONDUCTING PHOTO-POINT MONITORING

Photographic records are an important part of monitoring your grasslands. Photo-point monitoring involves taking three photos of the same site regularly with every assessment.

Comparison of these photos, along with the written notes made when they were taken, will give useful information about the status of your grassland—is the health of your grassland community improving, stable, or deteriorating? Consistent and repeated comparisons over time are key to effective monitoring.

Over time photo-point monitoring documents changes in the vegetation. It yields objective and visual documentation of the plant community (general species composition and structure). When applied consistently – yearly or every other year – photo- point monitoring provides an effective visual tool for comparison of the grassland community. PHOTO BRUNO DELESALLE

Assessing grassland status and trend over time is most accurate when you use a combination of grassland assessment and photo- point monitoring. This dual approach ensures that all indicators of grassland status are assessed and recorded for future reference, which is critical to repeatable and accurate comparisons. This will help you determine if your management strategies are achieving anticipated goals. They also help you make decisions regarding necessary management changes.

How to Do Photo-Point Monitoring This section takes you through the process of setting up your photo-points, taking the pictures, and storing your records.

GRASSLANDS CONSERVATION COUNCIL OF BRITISH COLUMBIA INTERPRETING RESULTS

The grassland status score is a cumulative evaluation of the five indicators assessed in the survey area. It provides you with an immediate appraisal of the status of the site, and possible impacts of current management practices.

Assessments of the same site over time will tell you whether your management is maintaining or changing grassland status. Depending on the direction of this trend, you may want to continue with your present management system or make changes that will help you achieve your objectives. The final score of the grassland assessment is out of 100 possible points. Although this score provides an overall rating of site status, do not overlook the importance of the scores for individual indicators, as they can reveal a lot about grassland trends.

Interpreting Scores from Individual Questions The score from an individual question will allow you to take a closer look at a specific indicators or combination of indicators to help you review or formulate management objectives. Look at the highest possible score for each question, as this will tell you its importance relative to the overall rating. Question 1 = 40% of the total score Question 2 = 10% of the total score Question 3 = 24% of the total score Question 4 = 16% of the total score Question 5 = 10% of the total score For example, a reduction of key bunchgrasses over a period of three to five years will indicate a possible downward trend. Conversely, an increase in bunchgrasses will indicate an upward trend. New signs of erosion combined with bare soil and low litter levels will indicate a clear warning sign that a problem may be arising and you will want to investigate further and take timely action.

 *OUFSQSFUJOH3FTVMUT $IBQUFS  Monitoring Trends Trends in Grassland Status Your main method for assessing trends is to compare your grassland assessment scores and photos from one survey period to another. Repeated assessments tell you if your management practices are supporting your objectives. As well, repetition allows you to fine-tune management decisions and activities in response to the changes you have recorded about your grassland. A higher score indicates a grassland that is moving towards the Reference Condition while a lower score indicates a grassland Reference Condition Natural and human that is moving away from reference condition. If you have photo- events, such as monitored the site, repeated photos will visually complement the drought, fire, insects, survey scores. recreational activities, wildlife use, and Assessing Apparent Trend historical factors also contribute to changes Trend Feature Declining Stable Improving in grassland status.

The most important single indicator of change is a decline in cover of the dominant bunchgrasses and an associated increase in cover of small grasses, forbs, and sometimes shrubs. Low-growing bunchgrasses and forbs, such as Sandberg’s bluegrass and pussytoes are often more abundant as disturbance increases. PHOTOS BRIAN WIKEEM

56 Interpreting Results Chapter 7 57 Evaluating Your Scores on Large Pastures In a large pasture with variable terrain where several sample areas have been established, interpreting results can be challenging. Consider the following: • Vegetation will be different in swales, depressions, gullies or at the toe of a hill. This is mainly due to higher moisture availability. Plant communities on wetter sites will recover more rapidly from grazing pressure than drier sites, such as ridges, rocky outcrops and south facing slopes. A common • Uneven distribution of livestock and grazing pressure throughout management goal is the pasture will result in areas with differing amounts of use, and to provide sufficient consequently, different impacts to the plant community. forage for livestock • The interpretation of monitoring results will depend on while having a small consistency of where, how, and when you monitor. but acceptable impact on the environment.

Grasses Collecting a grass sample for proper identification: 1 Record date and location of collection site, as well as any habitat features you can note such as “moist streamside” or “dry south- facing slope.” Spreading Needlegrass 2 Record growth form. Does the sample appear to be growing in a defined “bunch” or does it appear to be growing throughout a given area forming “sod-like structure?” 3 Carefully remove a portion of the grass with several intact leaves, seed heads and roots, if possible. 4 Roll the grass sample loosely in a newspaper tube and tape the ends off or place in a plastic bag. DO NOT PRESS THE SAMPLE. This is very important for proper keying and identification of grass samples. If the sample is too long for the paper tube or bag, gently fold it in half before placing it in a tube or bag. It is best to identify samples as soon as possible. However, if this is not possible, allow the sample to dry in the tube or bag and key out at the earliest convenience. Note: Pressing or squashing grass samples will alter features required for keying and identification.

Other Plants Collecting other plant samples for proper identification: 1 Record date and location of collection site, as well as any habitat features you can note such as “moist streamside” or “dry south- facing slope.” 2 Record or note flower color. The colour often fades when drying sample. For identification of other grasses and plants, refer to the following 3 Carefully remove a portion of the plant with intact leaves, flower guides: head, and some roots if possible. 4 Gently place sample in a plastic bag. If not identified Plants of Southern Interior British Columbia, Edited by Parish, Coupe, immediately, press sample between pieces of paper in a large Lloyd. Printed 2006.
