Year End Report for the 2019 Botanical Survey Season 5

EXECUTIVE SUMMARY

Green Diamond Resource Company (GDRCo) botanical technicians surveyed a total of 51 timber harvest plans covering approximately 8908 total acres. A total of 44 plans were surveyed to completion; two plans were initiated in 2017 and completed in 2019; two plans were initiated in 2018 and were completed in 2019; and seven plans were initiated in 2019 and will be completed in 2020. The 2019 floristic survey season commenced on March 4th and terminated on August 30th with an estimated 130 field days. A total of 164 new California Rare Plant Rank (CRPR) 1-2 BotID#s were generated representing 10 taxa. It is worth noting that 77 of the 164 new CRPR 1-2 BotID#s are previously unrecorded populations of Monotropa uniflora. A total of 123 new CRPR 3-4 BotID#s representing 15 taxa were generated as part of a continued commitment to collecting spatial and habitat data for uncommon species. There were no State or Federally listed Rare, Threatened or Endangered species observed during the 2019 survey effort.

Within the Coastal Lagoons and Little River Botanical Management Area (CL/LR BMA), five harvest plans were reviewed and three received surveys in unique habitats. Running pine (Lycopodium clavatum) was the most prevalent uncommon plant encountered in the harvest plans.

Per GDRCo’s Master Agreement for Timber Operations (MATO), the botany crew surveyed 28 road points associated with the Annual Work Plan. This plan describes planned road maintenance activities for the operational year. The botany crew surveyed the road points and associated road segments of this plan for rare and sensitive species. Two detections were made during the 2019 survey effort: Sedum citrinum and Carex serpenticola. Neither of these detections was associated with a road point or a segment of road that is at imminent risk due to future operational activity, thus no mitigation measures are required at this time. A California Natural Diversity Database (CNDDB) entry will be created for each population.

A summary data set for all occurrences was prepared and submitted to the CNDDB on February 11, 2020. This report includes 287 field survey forms for all CRPR taxa discovered in 2019, 105 follow-up forms for 19 taxa, and the corresponding location data in ESRI File Based Geodatabase (FBGDB) format.

Monitoring for Montia howellii in the Salmon Creek Tract continued for a ninth consecutive year. Surveys were conducted by two 2-person technical teams from March 11th through March 28th for a total of 13 field days. In addition, a new vegetation cover sampling protocol was implemented this year, which involved an independent 2-person crew to sample vegetation and rock cover. 2019 was a good year for Montia howellii, as occupancy was

near record high. Long term results of the data still show a decreasing trend with a substantial amount of variability from year to year.

Potentially Rare Species Detected in 2019 As in previous years, populations of potentially rare species found in 2019 that could not be reliably identified are being tracked by a permanent GDRCo BotID#. Inability to make a positive identification was typically due to a lack of flowering individuals. This remains a constant challenge with members of the genera Piperia and Erythronium. are often detected in the spring by their which senesce by the time the plants in the later summer. Upon subsequent visits to the sites during the flowering season, are often not present due to herbivory and immaturity. This was the case on the following THP surveys this year for Erythronium: Big Red (2020), Goodman Prairie (2020), Bear Prairie (2019), and Roach Creek Hole (2020); and for Piperia: Bear Prairie (2019), Boulder Road, Bukers Prairie (2020), Goodman Prairie (2020), Hancorne 600 (2020), High Prairie Combo 19, Roach Creek Hole (2020), Smokehouse Creek, and SP-1000.

When positive identifications are made, the unique BotID# remains with the occurrence, but the species name which corresponds will be updated in the database to reflect final taxonomic determination. If populations are confirmed to be rare, then the corresponding CNDDB data will be submitted.

Non-Rare Species Detected in 2019 There are many populations of species that are not rare, but are being tracked with a permanent GDRCo BotID# for one of two reasons: they are closely related to a rare species or are an invasive species being monitored. Currently, spotted knapweed (Centaurea stoebe) is the only invasive species being monitored (see discussion below). The balance of non-rare species being tracked are those that are closely related to rare species and/or may have been first detected in a vegetative state and given a BotID# as a potentially rare species. We continue to track such species when they are confirmed as “not rare” as they provide valuable insight into where habitat and ranges of the rare and common species may overlap or, conversely, remain disjunct. A list of non-rare species detected in 2019 is presented in the table below.

Spotted Knapweed Monitoring at Sweet Flat, Mad River In 2013 the GDRCo botany department began collaborating with the Humboldt County Department of Agriculture to monitor and remove spotted knapweed (Centaurea stoebe) from the gravel bars along the Mad River near the City of Blue Lake. Spotted knapweed was initially detected in 2013 along the Mad River at three locations south of the Mad River Hatchery. One of these locations is at “Sweet Flat” which is best accessed from private GDRCo roads.

In 2014, the site was surveyed and no plants were detected. The gravel bars along the river were surveyed to the south of the site and no other populations were detected in these regions either. The site was surveyed in 2015 and one population was detected and removed; the gravel bars along the river were surveyed to the south of the site again and no additional plants were detected. In 2016 the botany crew removed approximately 100 spotted knapweed plants from the site. In 2017 the crew removed approximately 30 spotted knapweed plants. In 2018 the botany crew removed approximately 50 plants and disposed of them off site. The infestation of yellow star thistle (Centaurea solstitialis) at the site that was first detected in 2016 was still present in 2018, and appeared larger and more expansive than in 2017. A couple of trash bags full of star thistle were removed and disposed off site, but this was just a fraction of the present population. In 2019, the crew removed a total of four spotted knapweed plants, as well as several yellow star thistle plants, and disposed of them off site. A list of the species found at Sweet Flat in 2019 is below.

COASTAL LAGOONS AND LITTLE RIVER BOTANICAL MANAGEMENT PLAN STATUS

GDRCo and CDFW agreed that the long-term survey protocol for THPs within the Coastal Lagoons and Little River BMA, effective 2009, is as follows:

1. RPFs shall conduct focused surveys for all THPs within the Coastal Lagoons and Little River BMA. RPFs shall be responsible for reporting the presence of any unique, high quality, sensitive plant habitat within their project area, e.g. bogs, well developed lakes or ponds, coastal prairie or large mossy boulders or rock outcrops. When Lycopodium clavatum is encountered within THP areas voluntary, non- enforceable PPMs will be applied. These PPMs include establishing ELZs for select populations and retaining non-merchantable . If other sensitive species are observed, the RPF will consult with GDRCo botany staff.

2. Botanical technicians shall survey unique, high quality sensitive plant habitats within THPs as identified by RPFs. If sensitive species are discovered appropriate PPMs shall be applied.

3. Botanical technicians shall monitor a subset of L. clavatum populations on a yearly basis. Initially, monitoring activities will focus on pre and post-harvest monitoring of populations protected with

Year End Report for the 2019 Botanical Survey Season 12

voluntary, internal PPMs that were implemented for plans submitted after July 8, 2008. Revisions to internal PPMs may be made based on monitoring results.

4. Botanical technicians will survey unique or high quality habitats outside of THPs when they are identified. The intent is to find and survey areas within the BMA that have the greatest likelihood of supporting sensitive species, regardless of whether or not the habitat would ever be impacted by timber harvest operations.

Five THPs within the Coastal Lagoons and Little River BMA were reviewed by the botany department in 2019 and some uncommon species of plants were detected during focused surveys. Surveys predominantly focused on rocky outcrops and isolated wet areas. Between the forestry and botany crew, nine new populations of running pine (Lycopodium clavatum) were detected in three THPs. Three populations will avoid the direct impacts of timber harvest operations due to their locations within RMZs and habitat retention areas. Other uncommon plants detected in the BMA this season included one population of Pacific golden saxifrage (Chrysosplenium glechomifolium).

MONTIA HOWELLII MONITORING IN SALMON CREEK Based on the results of the power analysis that West Inc. conducted on the 2011 through 2013 monitoring data for Montia howellii in Salmon Creek, the monitoring protocol was revised to focus on detecting trends of occupancy in 2015. This has subsequently resulted in a change to the sampling protocol and much of the data collection has been simplified. The current monitoring protocol is as follows:

Objectives: 1. Determine if the trend in occupancy of Montia howellii (MOHO) growing along the mainline Salmon Creek road system is increasing, decreasing or stable over time.

2. Determine if MOHO occupancy is correlated with covariates that can be altered through management. A. Road surface type as percent cover of dirt and percent cover of rock (cumulatively equal to 100%). B. Percent cover of competing vegetation – we will measure cover of plants at ground level other than MOHO, including straw mulch or logging slash when they are at densities that clearly prevent plants from growing

3. If the population (percent occupied segments) shows a trend of significant decline, as evidenced by either a significant abrupt change in one or two years, or a significant long-term trend over several years, consult with CDFW and attempt to coordinate road management activities with activities designed to maintain MOHO (e.g. if percent occupancy is highly correlated with specific habitat variables then manage for more of those).

Sampling Plan: 1. The sampling universe includes the GDRCo Salmon Creek tract mainline road system on the north side of Salmon Creek, with the exception of one road that crosses to the south side of Salmon Creek. That road is included until it reaches the GDRCo property line. The roads that are classified as mainline roads for the purpose of this study are the main roads that are projected to be used and maintained over the next ten years (2011-2020). For the most part the roads included provide an access loop through the extent of the property on the north side of Salmon Creek. The significance of this continuity is that it should allow us to account for plants anywhere they may have migrated along the mainline. The majority of the mature timber in this tract has already been harvested and the main area left to harvest is at the northeastern portion of the sampling universe. The mainline road accessing this area has been reconstructed and newly constructed in recent years and while MOHO has not been found on this road yet, it does contain potential habitat. There are other roads included that to date have not supported MOHO, as well as roads that have supported large numbers of MOHO until they were rocked a few years ago. Some of the roads included may get more or less use than others over the course of the study. The sampling universe contains road segments with both natural and rocked surfaces. Additional rocking may occur in the years to come. We anticipate that the habitat quality along roads or portions thereof will fluctuate throughout the course of the study.

2. The roads in the sampling universe were designated as routes with beginning and end points and then routes were ordered in space and divided into 50 foot segments that will serve as sample plots. The width of the road varies and plants are often found at the margins and in the middle, so the plots will not have a fixed dimension across the width of the road. Each 50 foot segment was given a permanent route ID and segment ID with fixed start/stop UTM coordinates that can be loaded into GPS units. *There are three road segments that are shorter than 50 feet, but longer than 25 feet so we will keep them. There are a total of 1551 road segments.

Year End Report for the 2019 Botanical Survey Season 14

3. Stage 1 consists of determining presence or absence of MOHO in the sample plots or road segments (SID). Sample plots selected by a generalized tessellation stratified (GRTS) sample of 50-foot road segments to ensure sample plots are spatially balanced (interspersed) throughout the population with few if any adjacent to one another. The GRTS sample will consist of a specially randomized list of road segments that preserves spatial balance in adjacent sets of segments. The first 110 segments on this list were formerly placed in a group called Panel 1. All of Panel 1 was sampled on an annual basis for the first 4 years of the study. The subsequent groups of 20 segments were assigned to panels numbered 2 through 73. Road segments in panels 2 through 73 were to be sampled twice every 5 years on a rotating basis. During the first five years of the study, a total of n = 130 sites were being sampled (Panel 1 plus one of Panel 2 through 6). After Year 5 of the study, a total of n = 150 segments were to be sampled (Panel 1 plus a previously unvisited panel plus a previously visited panel). After four years of conducting the study under this sampling regime, it was determined that the effort required to complete the number of sites was too great to remain sustainable for the long term. The proposed revisions to the sampling protocol are outlined below.

Revision to Sampling:

The goal for revising the sampling protocol is to have two groups of surveyors complete the work in two weeks, or 10 sample days. To achieve this goal, we propose that the sample number be reduced and that the survey protocol be simplified. By estimating that each group will be able to complete five sites per day, this makes 100 SIDs over the 10 sampling days. This seems reasonable and achievable. There is some concern regarding destructive sampling to the 110 permanent sites. It would be ideal to be able to give some of these sites a rest period. In addition to this, having faster replication of the 80 (Panels 2-5) that have been sampled already could also be beneficial. There will still be sampling of new sites as well under the following scheme: a) Panel 1, which consists of 110 SIDs, gets divided into three panels: Panel 1, Panel 2 and Panel 3. Two of these will have 37 SIDs and one will have 36. In order to give some of these permanent sites a resting period, a two year on and one year off strategy will allow us to do this without losing how a prior year at a SID directly impacts the following year (since they are annual plants). This strategy would look like this: Year 1: Panel 1, 3 Year 2: Panel 1, 2 Year 3: Panel 2, 3 Year 4: Panel 3, 1 Year 5: Panel 1, 2 (Etc.) b) Panels 2-6, which each consist of 20 SIDs, but collectively make 100 SIDs, will remain the same. Their panel numbers will change since Panel 1 has been divided into three new panels. Their new panel numbers will be 4-8. These panels of 20 will cycle and repeat every five years e. g. 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, etc. c) If we take two of the panels from the first group (Panels 1-3), this will make 74 SIDs. If we add one of the other panels from the second group (Panels 4-8), this will make 94 SIDs. We will always sample eight new sites, and since the number of permanent SIDs we sample can vary slightly year to year, some years we will survey 101 total SIDs and some years we will survey 102 (36+37+20+8=101; 37+37+20+8=102).

4. Stage 2 consists of determining patch size in the selected sample plots. Each sampled plot will be divided into five 10-foot quadrats that extend across the entire width of the road. Presence or absence of MOHO will be recorded for each of the five quadrats in the sampled plot. To estimate probability of detecting MOHO assuming it is there, two surveyors will make independent presence/absence

Year End Report for the 2019 Botanical Survey Season 15

observations and record their data separately and discretely. When complete the two surveyors will compare their P/A to make the P/A union. When there are discrepancies the two surveyors will visually check the quadrat to see if there was a true miss by one surveyor, a misidentified plant or if the plant could not be relocated. If it was a misidentified plant or could not be relocated, a note is made on the datasheet, since this leads to cases where their union is not a simple addition of P/A1 and P/A2. Boundaries of the quadrats will be delineated using stakes/spikes at ten foot intervals at both edges of the plot (outside road margins).

Each surveyor will make visual estimates of the percent cover of rock to the nearest whole percent (0-100) in each quadrat while they are doing the P/A survey. Each surveyor will also make a visual (ocular) estimate of the percent cover to the nearest whole percent (0-100) of competing vegetation in each quadrat. Once the surveyors have completed the segment, they will come to agreement on their independent assessments to determine the union value for the environmental variables.

A cursory analysis of the occupancy data from 2011-2019 was completed and is presented below in Figure 3. The results from each year’s survey are shown in Figures 5-13 and the overall harvest activity is shown in Figure 4. The total numbers for 2019 show a significant increase in occupancy from 2017 and 2018, which brought the trendline to nearly flat. In years 2012 and 2015 the population showed declining occupancy numbers then upward trends in 2013, 2014, 2016, 2018, and 2019. This pattern of decline following the removal of disturbance is consistent with the observations reported by Renner et al. 2012.

2019, the evolution continues:

During data review and initial analysis of our 2018 data, it became apparent that many of the ocular estimates for percent vegetation and rock cover among surveyors were highly variable and seemingly inconsistent. To calculate the significance of these discrepancies and make our data more useful, we implemented an additional vegetation sampling protocol in 2019. The point intercept method was used following the protocols outlined in Coulloudon et al. 1999. This protocol involves systematic estimation of percent cover of both rock and vegetation in all plots.

In our application, the point intercept method involves stringing a transect across the middle of each quadrat in the segment, with the transect oriented perpendicular to the road. The vegetation and rock cover was assessed every half-foot along the transect line using the point intercept method. See Figure 2 for a diagram of the plot/transect layout.

Year End Report for the 2019 Botanical Survey Season 16

Figure 2. Point-intercept transect layout on MOHO segment.

After reviewing and comparing our ocular estimates and point-intercept estimates on the 2019 plots, we discovered that there was no consistency or significant pattern between our ocular estimate data and the point- intercept data. Given the proven precision and accuracy of the point intercept method (Coulloudon et al. 1999), we can only assume that the ocular estimate data is both inaccurate and imprecise. While this is a somewhat disheartening realization, it is useful to get some clarity on the effectiveness of our methods. Looking forward into 2020, we will omit the ocular estimation of vegetative cover and rock cover from the protocol, and only use the point-intercept estimation.

YEAR END MITIGATION SUMMARY

Survey efforts in 2019 yielded 438 new BotID#s. New discoveries of ghost pipe (Monotropa uniflora; MOUN) were particularly abundant, with 77 new populations discovered; most of these occurrences came from THPs in the Hunter and Wilson Creeks tract, where we surveyed 1,352 acres across seven THPs. Mitigation measures for this species largely followed GDRCo’s programmatic measures and only strayed from that protocol when circumstances required. Also of note is the number of occurrences of various Piperia species. A total of 136 occurrences of various Piperia species were detected, but only 26 of those were the rare Piperia candida. The unidentified Piperia species are included in the table below as some of those were afforded protection measures.

The diversity of species mitigated for in 2019 was much greater than recent years. This diversity called for greater creativity when writing/implementing mitigation measures. For example, the populations of SIMAPA were all found growing in an woodland along the edge of a timber harvest unit. This woodland was encroached by Doug in many places, which was shading out the habitat for the SIMAPA. To mitigate the impacts of the adjacent timber harvest and the encroachment, oak trees were retained near the population, while allowing for the harvest of fir trees and maintaining 50% canopy cover. We will monitor these populations in the future to see how plants respond to these mitigation measures. The mitigation measures for the serpentine endemic species (SECI and ROGYSE) have yet to be developed as surveys on that THP are still outstanding.

FOLLOW UP VISITS

Bald Mountain milkvetch (Astragalus umbraticus) Three populations (BotID#35361, #1362, #1361) from the plan CDF#1-17-137H (GDRCo No. 51-1702) were revisited. Timber harvest operations and road maintenance activities were completed in 2019. Road work adjacent to BotID#36361 has created ideal habitat for the population. This population will be revisited in 2020 to assess the response of this plant to standard road maintenance operations. The other two populations received an avoidance ELZ and to limit side casting off the road prism during road maintenance activities to retain the source. There were individuals observed at both locations during the follow up visit in 2019, and both will be revisited in 2020 to monitor the populations’ response to the disturbance.

One population (BotID#1789) from the plan CDF#1-17-144H (GDRCo No. 51-1707) was revisited. This population was originally found growing on an old seasonal road that has since become overgrown by and trees. Road maintenance activities aren’t scheduled to occur until early 2020. There is likely seed stored in the soil at this site, so when the area is opened up again, this seed source may be revived. This population will be revisited after road maintenance activities are complete.

Two populations (BotID#35667 & 398) from the plan CDF#1-17-143H (GDRCo No. 51-1706) were revisited. Timber harvest operations were initiated for this plan in 2019. All four populations in this plan (BotID#s 31592, 398, 35667 and 35668) will be monitored in 2020 and the next four years. BotID#35667 was potentially going to be impacted by road maintenance activities in 2019, but a follow-up visit discovered the population had not been directly impacted and was healthy and flowering at the time of the visit. BotID#398 was associated with an appurentenant road to this plan and operations had taken place prior to the followup visit. Approximately 250 plants were observed along the margin of the road segment with extensive available habitat formed by road maintenance operations.

Bensoniella (Bensoniella oregana) Ongoing monitoring of Bensoniella oregana (BEOR) populations continued through 2019. The transplanted population (Bot ID#204) was found to be out competed by other low lying herbs, particularly . The number of individuals observed has declined at the site of the transplanted individuals; competition with other species has threatened stability. However, there were twice as many individuals observed at the original site since the previous follow-up visit last year. It appears that the original site, despite its vulnerability to timber operations, has consistently provided more suitable and stable growing conditions. The second transplanted population (Bot ID# 31638) was visited and observed to be stable in numbers. The habitat conditions were similar to those of the previous two years with the exception of a notable lack of ground-level light. The population seems to have shifted, with numerous individuals accounted for in areas where no pin flags were present. The third population of BEOR that was visited was in good health and numbers, showing signs of flowering, and growing in excellent habitat.

Bear sedge (Carex arcta) One population of Carex arcta (CAAR) growing by Christmas Prairie Lake was found to be persisting and stable (BotID# 30228; CDF#1-17-118H; GDRCo No. 27-1702). There is competition by native wetland shrubs growing near the lake margin at this site, as well as from non-native shrubs on the decommissioned road surface. Several botany crew members removed Scotch broom (Cytisus scoparius) at this site on the decommissioned road surface to help relieve some competition and hinder further establishment and maturation of these invasive non-native plants.

Coast fawn lily (Erythronium revolutum) The follow-up results for Erythronium revolutum (ERRE) were promising. Almost all populations that were targeted for follow-up monitoring were found extant and healthy. The one population that was not found to be extant had not been revisited for 10 years, but had originally received plant protection measures in 2001, with the most recent detection of individuals in 2009. The mitigation was still intact at this site, but no individuals were observed. One population (Bot ID#305) was found to be far more expansive than originally recorded, as a more thorough survey of the surrounding area for a current THP (1-18-144HUM) uncovered a contiguous population of plants running side slope and upslope of the original documented occurrence. This is the largest population recorded on GDRCo’s ownership to date, with an approximated 7000 individuals.

Pacific blue field gilia (Gilia capitata ssp. pacifica) The Gilia capitata ssp. pacifica (GICAPA) populations monitored this year produced healthy foliage and robust flowers. The heavy rain from the prior winter season seems to have bolstered growth for these plants.

Running Pine (Lycopodium clavatum) Several Lycopodium clavatum (LYCL) populations received follow-up monitoring throughout the 2019 season. The programmatic protections these plants receive within the Coastal Lagoons Botanical Management Area are generally effective at keeping the individuals on the landscape for at least a decade post-harvest. In fact, the majority of the sites we revisited in 2019 (21 BotID#s) were 10+ year old occurrences. More than half of these (14 BotID#s) were found extant, most of which received programmatic protections and a few that received no protection. There were several that were not found, but were likely extant and could not be relocated due to error in accuracy of GPS coordinates mapped. In these instances, without refreshed flagging, it is exceedingly difficult to pinpoint where the original population once was.

Ghost pipe (Monotropa uniflora) For the 2019 survey season, we made a modest effort to monitor Monotropa uniflora (MOUN) populations. About one third of these occurrences received no mitigation, and the other two thirds received programmatic protections or other mitigation measures. Overall, the populations that received programmatic protections or other mitigation measures were found extant and doing well, and even some that received no protections were still found to be extant. The five populations that were not found during follow up visits were a mix of those that received programmatic protection and those that received none. Those that received programmatic protection but were not found had intact mitigations at the site and in previous years were found to be both extant and stable. This highlights the variable response in growth patterns we tend to see with this species, possibly due to seasonal weather patterns.

Seacoast ragwort (Packera bolanderi var. bolanderi) One population of Packera bolanderi var. bolanderi (PABO) was revisited in 2019. The population was located and found not only to be extant, but thriving. Mitigation was intact and successful, and the surrounding stands had been harvested.

Rein orchid (Piperia sp.) In 2019, we surveyed several plans in the spring that provided excellent habitat for Piperia, and 136 new occurrences were recorded. During the time of survey, were not yet developed at all, or enough, to make a positive determination. We revisited all of these populations to get a positive ID later in the season. Of these occurrences, 50 were identified to the species level, and of the 41 total occurrences of Piperia candida found on GDRCo property 26 were discovered in 2019. Due to the volume of Piperia species we were dealing with in current THPs, the older occurrences were lower priority. However, we did revisit 16 old occurrences, and made a positive ID on five.

Checkerbloom (Sidalcea sp.) The population of Sidalcea that was detected in 2017 in the Knutz Creek THP (1-16-084H) was finally determined to be Sidalcea malviflora ssp. patula (SIMAPA). There were also several new SIMAPA populations discovered in the Goodman Prairie THP (1-18-176H) that will be monitored over the next five years.

Robust False Lupine (Thermopsis robusta) This year we opted to implement a minor habitat restoration effort for Thermopsis robusta (THRO). It remained true that the populations of this plant we revisited were extant, but many of them in decline due to overtopping by the surrounding vegetation. This was generally due to increased competition from woody species such as tanoak, Douglas- fir, and manzanita. To mitigate these populations becoming shaded out, we cleared vegetation around several populations that are growing road-side in the High Prairie and Christmas Prairie area of the property off Snow Camp Road. We will be monitoring these populations next year to see if there is a favorable response to providing more access to sunlight and reduced competition with surrounding shrubs and trees.

HABITAT IMPROVEMENT PROJECTS There are notable challenges facing the Thermopsis robusta populations on our property. The mitigation strategy employed with them historically has been avoidance. This has allowed for the surrounding growth of vegetation to overtop individuals and begin shading them out. This has been observed in follow-up visits over the past few years. While populations remain extant, they have been observed struggling to grow due to heavy competition for sunlight with other vegetation. To mitigate this challenge, we endeavored to improve some habitat for populations that were growing on our road system in the Christmas Prairie and High Prairie areas of the property, off Snow Camp Road. We visited the sites over the course of the year and cleared vegetation with hand tools in the surrounding area of individual plants, giving them roughly 6-10 feet of clearance in all directions. One population, which was treated in the winter responded well to the extra sunlight, producing fully bushy plants instead of lanky, sun deprived stems as were present years previous.

Additionally, we removed approximately 600 square feet of Scotch broom (Cytisus scoparius) shrubs that had established in the bog adjacent to Christmas Prairie Lake. These shrubs had begun encroaching into the habitat of a Sanguisorba officinalis population in the area. This bog is a unique feature and habitat for our property, and we hope to keep it in pristine condition. We also removed isolated Scotch broom shrubs that had begun to establish on a decommissioned seasonal road where a population of Carex arcta is growing in another location around Christmas Prairie Lake to inhibit encroachment by non-native species.

We look forward to pile burning this broom and monitoring these sites to observe the response, which we expect to be favorable.

Year End Report for the 2019 Botanical Survey Season 40

PROGRAM GOALS FOR 2020 No changes are proposed to the protocols as delineated in the Sensitive Plant Conservation Plan and the associated Property-wide Consultations. The goals as listed below are intended to supplement the existing botanical program, some are experimental in nature, and none are intended to be enforceable actions associated with CDFW’s evaluation of GDRCo’s botanical program.

I. Continue to develop a robust habitat maintenance plan for special status species with specific life history requirements. i. Provide ongoing management of special status plant occurrences. Depending on the species, this management will take different forms, i.e. promoting controlled disturbances for disturbance loving species, controlling invasive weeds, or increasing sunlight at a given site and so forth. II. Implement a coordinated inter-department effort to systematically document and map non-native and invasive plant species on the property. Identify areas where treatment measures can be taken to control the spread and establishment of those species. III. Focus on updating and refining the GDRCo . Share the data from our collection with the California Consortium of Herbaria (CCH). i. Become a participating member of CCH by sharing our herbarium specimens and data associated with them. ii. Focus more efforts to identify, collect, and preserve regionally unique flora during the field season. iii. Explore efficacy of photographing specimens from the GDRCo herbarium to catalogue in the CCH database.
