Year End Report for the 2017 Botanical Survey Season 3

EXECUTIVE SUMMARY

Green Diamond Resource Company (GDRCo) botany technicians surveyed a total of 60 timber harvest plans covering approximately 12,929 total acres. A total of 47 plans were surveyed to completion; 7 plans were initiated in 2016 and completed in 2017; and 6 plans were initiated in 2017 and will be completed in 2018. The 2017 floristic survey season commenced on March 8th and terminated on September 28th with an estimated 130 field days. A total of 106 new California Rare Plant Rank (CRPR) 1-2 BotID#s were generated representing 5 taxa. It is worth noting that 46 of 106 the new CRPR 1-2 BotID#s are previously unrecorded populations of Erythronium revolutum. A total of 187 new CRPR 3-4 BotID#s representing 13 taxa were generated as part of a continued commitment to collecting spatial and habitat data for uncommon species. No State or Federally listed Rare, Threatened or Endangered species were identified during the 2017 survey effort.

Within the Coastal Lagoons and Little River Botanical Management Area (CL/LR BMA), 11 harvest plans were reviewed and 8 received surveys in unique habitats. Three populations of seaside bittercress (Cardamine angulata) were detected in the BMA, which considerably expanded the known range of this species. In addition, several populations of running pine (Lycopodium clavatum) and other uncommon native plants were identified including Oregon goldthreads (Coptis laciniata), Pacific golden saxifrage (Chrysosplenium glechomifolium) and nodding semaphore grass (Pleuropogon refractus).

A summary data set for all occurrences was submitted to the California Natural Diversity Database (CNDDB) on March 13, 2018; this package included 285 field survey forms for all CRPR taxa discovered in 2017; and 115 follow-up forms for five taxa and the corresponding location data in ESRI File Based Geodatabase (FBGDB) format. Note that 98 of the 115 follow-ups were associated with mitigated Monotropa uniflora populations.

Monitoring for Montia howellii in the Salmon Creek Tract continued for a seventh consecutive year. Surveys were conducted by a 4-person technical team from March 7th through March 17th for a total of nine field days. Results of the occupancy data show a decreasing trend and a substantial amount of variability from year to year. Downward trending occupancy is presumed to be associated with habitat loss associated with minimization of road use in compliance with the existing Road Sediment Reduction Plan as described in the South Fork Elk River Management Plan (GDRCo 2006).

Potentially Rare Species Detected in 2017

Populations of potentially rare species found in 2017 that could not be reliably identified are being tracked by a permanent GDRCo BotID#. Lack of full identification was typically due to a lack of flowering individuals; this has particularly been a problem with Piperia and Erythronium. Plants are often detected in the spring by their leaves which senesce by the time the plants flower in the later summer. Upon subsequent visits to the sites during the flowering season, flowers are often not present due to herbivory and immaturity. This was the case on the following THP surveys this year for Erythronium: Canyon Cr. Scramble, Knutz Creek, Tectah Forks and Roddy; and for Piperia: Boulder Creek South, Boulder Creek North, Knutz Creek, Long Prairie and RM-10.

When identifications are confirmed the BotID# will remain, 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 2017

Several populations of species that are not rare, but are being tracked by a permanent GDRCo BotID# for one of two reasons: they are either closely related to a rare species or are an invasive species currently being monitored. Currently, spotted knapweed 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 2017 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 plants and disposed of them offsite. The infestation of yellow star thistle (Centaurea solstitialis) at the site that was first detected in 2016, was still present in 2017. There are several known infestations of yellow star thistle throughout the watershed, and this location is likely just one of its newly colonized riverbars. A list of the dominant species found at Sweet Flat in 2017 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 trees. 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 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.

Year End Report for the 2017 Botanical Survey Season 8

Eleven THPs were reviewed in 2017 and several rare and uncommon species of plants were detected during focused surveys of eight THPs within the Coastal Lagoons and Little River BMA. Surveys predominantly focused on rocky outcrops, isolated wet areas, and coastal spruce flats. Three new populations (BotID#s) of seaside bittercress (Cardamine angulata) were detected in one THP, and due to their locations within Riparian Management Zones (RMZs), they will avoid the direct impacts of timber harvest. Seven new populations of running pine (Lycopodium clavatum) were also detected in five THPs: Two populations were protected with programmatic plant protection measures (25 ft. Equipment Limitation Zone placed around the population with merchantable timber harvested and sub-merchantable timber retained); four populations will avoid the direct impacts of timber harvest operations due to their locations within RMZs or Habitat Retention Areas; and the last population was not mitigated. Other uncommon plants detected in the BMA this season included populations of Trailing black currant (Ribes laxiflorum), nodding semaphoregrass (Pleuropogon refractus), and Pacific golden saxifrage (Chrysosplenium glechomifolium).

MONTIA HOWELLII MONITORING IN SALMON CREEK

Based upon 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. Revisions to the monitoring protocol are 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 DFG 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. 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.

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 5 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 4 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 2 groups of surveyors complete the work in 2 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 5 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 End Report for the 2017 Botanical Survey Season 10

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 5 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 8 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 5 10-foot quadrats that extend across the entire width of the road. Presence or absence of MOHO will be recorded for each of the 5 quadrats in the sampled plot. To estimate probability of detecting MOHO assuming it is there, two surveyors will make independent presence/absence 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 miss-ID or if the plant could not be relocated. If it was a miss-ID 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 five foot intervals at both edges of the plot (outside road margins) and then using string (hip chain) to create a grid. See the diagram in the field methods section.

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 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.

The 2014 monitoring effort for Montia howellii was conducted in the same manner as it was for the 2011-2013 years. The new monitoring protocol was implemented starting in 2015. West Inc. will integrate the data from past years to be able to continue with detecting the trend of occupancy within the Salmon Creek road system.

A cursory analysis of the occupancy data from 2011-2017 was completed and is presented below in Figure 2. The results from each year’s survey are shown in Figures 4-10 and the overall harvest activity is shown in Figure 3. The total numbers for 2017 show a sharp decrease, the lowest occupancy levels since the study began. It was anticipated that the 2017 occupancy data would show increasing occupancy rates given the significant increase in 2016-2017 rainfall, but the opposite proved true. In years 2012 and 2015 the population showed declining occupancy numbers then upward trends in 2013, 2014 and 2016. This pattern of decline following the removal of disturbance is consistent with the observations reported by Renner et al. 2012. We are also hypothesizing that our monitoring efforts are impacting the population – our heavy quad traffic and repeated disturbance is likely detrimental to the population.

YEAR END MITIGATION SUMMARY

2017 was a banner year, with 341 new BotID#s detected. New discoveries of coast fawn lily (Erythronium revolutum; ERRE) were particularly abundant, with 46 new populations discovered. The Boulder Creek North harvest plan was a highlight of the survey season, with excellent rare plant habitat throughout, hosting the majority of coast fawn lily populations (33) for the year. A few different mitigation measures were implemented for the populations in this plan; along with the typical 50 foot no harvest buffer, we also implemented a 25 foot no harvest buffer surrounded by another 25 feet of selective harvest on select populations in an effort to test for shade tolerance and response to increased light input in the context of a smaller no-cut buffer. This experimental treatment will be monitored prior to expiration of the permit life and a follow-up form submitted to CNDDB.

Ghost-pipe (Monotropa uniflora; MOUN) was also found and mitigated in great numbers this season. Some of the new mitigation measures were implemented in an attempt to have a more adaptive approach to the conservation of this species. Most of the mitigated populations were protected using the programmatic mitigation measures, but in the Rowdy Divide plan, a new strategy was implemented which resulted in one large core mitigation area conisiting 12.2 acres of contiguous forest that will serve as an in-situ conservation area for the species. This was in lieu of protecting smaller isolated populations scattered throughout the harvest plan area.

To mitigate the impacts of a newly constructed seasonal road through an area of California oat grass prairie (Danthonia californica Herbaceous Alliance; an S3 sensitive natural community) a series of plant protection measures were proposed. This included an outsloped road with no turnouts, no staging or decking areas, and no side casting of soil beyond the road prism. The road shall also be heavily waterbarred, strawed and seeded using certified weed free seed. Additionally, annual monitoring will be conducted after operations are complete to detect and prevent the establishment of non-native invasive species.

BENSONIELLA MONITORING

During the 2016 season and in accordance with the Wiggins North THP (1-15-119H), one population of Bensoniella oregona was transplanted from a proposed road grade that was to be impacted by timber harvest activities. A suitable, unoccupied site in a nearby drainage was chosen as the transplant site. On 6/8/2016 plants were removed and transported to the new location. Plants were placed in 17 distinct clumps and each site was pin-flagged. A follow up visit occurred on 6/16/2017. Plants were present at all 17 locations and appear to be growing well at the new site. This population shall be monitored for an additional two years to assess the establishment of this transplant site.
