POTENTIALLY RARE SPECIES DETECTED IN 2013

Populations of potentially rare species found in 2013 that could not be reliably identified, but 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. 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. When identifications are confirmed the BotID# will remain, but the name attached to it will be updated in the database to reflect final taxonomic determination. If populations are confirmed to be rare, CNDDB data will be submitted.

NON-RARE SPECIES DETECTED IN 2013 THAT ARE BEING TRACKED Populations of species that are not rare, but are being tracked by a permanent GDRCo BotID# , typically for one of two reasons; 1. They are closely related to a rare species, or 2. They are an invasive species. Primarily these are species that are closely related to rare species and may have been first detected in a vegetative state and given a BotID# as a potentially rare species. We have chosen to keep track of them even 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 remain disjunct.

Coastal Lagoons and Little River Botanical Management Plan (CL&LR BMP) 2013 Status Report

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.

There were 17 THPs in the BMA that were reviewed in 2013. Ten of those received habitat-focused surveys conduced by botanical technicians. Running pine was protected in 6 of the 17 THPs. Eight previously documented running pine populations were revisited in 2013. There still have not been any new rare species detected within the BMA. No additional sites of the flaccid sedge (Carex leptalea) have been detected. The southeastern “foot” of the Little River Hydrological Planning Area (HPA) is known to be floristically unique in comparison to the rest of the BMA, and THP units in this area are

Page 10 of 56 completely surveyed for that reason. Oregon goldthread (Coptis laciniata) is known to occur near the headwaters of Little River, in that portion of the BMA. During a follow-up visit to one of these populations in 2013, a fawn lily leaf was observed. Based on the known distribution of coast fawn lily and the forest composition in this area, it would not be a surprise if the species was found to occur here. The endemic, but not rare, California fawn lily is not known to occur in this area either.

Oregon goldthread, Coptis laciniata A. Gray (COLA) 2013 Status Report

This species was noted as present on GDRCo property in the course of conducting complete floristic surveys of Timber Harvest Plan (THP) areas prior to the species being assigned a California Rare Plant Rank (CRPR) of 2.2 in October of 2006. Since then, every population detected on the property has been mapped in GDRCo’s GIS rare plant layer and given a permanent and unique BotID#. As of the close of the 2013 field survey season, GDRCo has documented 87 “populations” or unique BotID#s. In our case, what constitutes a population, given its’ own BotID#, is somewhat subjective and has evolved more as a data management tool than a reflection of true population biology terms. Generally, if a patch or colony of plants is separated by more than 100 feet from other groups of plants they are given their own BotID#. In the rare instance that the plants are truly abundant and well distributed throughout a timber harvest unit, protected populations may have each been given a unique BotID# while others may have been grouped. When populations are grouped, information about each “colony” in the group is maintained. In 2013, 1,000 acres in the Broken Rib Mountain quad, the most northeast tract of GDRCo, were surveyed and in many places Coptis laciniata was found to be the dominant herb. Since the final THP boundaries in this area have not been delineated, it was premature to develop mitigation measures and populations were grouped into areas much larger than is typical for BotID#s. This still resulted in the addition of 21 new BotID#s, bringing the year-end total to 87 Coptis BotID#s.

Since the designation of an element occurrence (EO) in CNDDB follows more of a metapopulation approach with the defined rule of a ¼ mile gap between EOs, it provides a better frame of reference for discussion of the abundance and distribution of this species on GDRCo property. As of March 21, 2014, 29 of the 104 EOs (nearly 30%) are on GDRCo property (or what was GDRCo property when plants were detected and reported). Since 58 of the 104 EOs are in Mendocino County where GDRCo does not have property, 63% of the remaining EOs (Humboldt and Del Norte counties) are on GDRCo property. In most cases the entire EO is situated on GDRCo property, but there are instances where the EO was initially based on historic data and we have reported populations in the nearby vicinity or the EO includes populations on an adjacent landowner. The 21 new BotID#s in the Broken Rib Mountain quad will result in the addition of a few new EOs based on an evaluation of the distribution of the new detections. One other new BotID# from 2013 is further than ¼ mile from another EO, so it will likely be given its’ own EO. Unless other landowners have also reported several new detections in areas outside of current EOs, once the 2013 data is assigned EOs, at least 30% of all the C. laciniata EOs in California will be on GDRCo property.

Populations on GDRCo range from immediately south of the Oregon border at the Hwy 199 tunnel (Broken Rib Mountain quad) south to just a few miles south of Hwy 299 between Blue Lake and Willow Creek. Populations are found at least eight miles inland from the coast and between 700 to 3,050 feet above sea level. BotIDs are clustered in the North Fork Mad River Hydrological Planning Area (HPA) (Blue Lake quad) and at the junction of that HPA and the Mad River and Redwood Creek HPAs (Blue Lake, Lord-Ellis Summit, Korbel and Maple Creek quads). Populations are also scattered across the Interior Klamath HPA (Blue Creek Mountain, Holter Ridge, Johnson, Bald Hills, French Camp Ridge quads). An isolated cluster (21 new BotIDs) occurs by the Oregon border in the Elk Creek and West Fork Illinois River watersheds in the Broken Rib Mountain quad. Note that the 6 BotIDs in the Blue Creek Mountain, Willow Creek and eastern Lord-Ellis Summit quads are on parcels that GDRCo no longer owns.

The species is known to be tolerant of both drought and shade with its’ small, thick evergreen leaves. It is highly clonal, slow growing, long-lived and able to occupy even the densest forest (Lindh B. C.,

Page 12 of 56

2003). On GDRCo, healthy populations have been observed under a range of 0-90% overstory canopy cover. GDRCo populations are typically associated with the Pseudotsuga menziesii and the Pseudotsuga menziesii-Lithocarpus densiflorus Forest Alliances (Sawyer, et al., 2008) and plants are most often found intermixed with small amounts of sword fern and salal (table 1). A moderate amount of Sequoia sempervirens is often present, and while Halpern (1989) found C. laciniata in Oregon to be strongly associated with dense subcanopies of Tsuga heterophylla, it was only noted on 20% of the C. laciniata CNDDB field forms on GDRCo. While the species is known to occur most frequently and in the greatest abundance in late-seral Douglas-fir forests (Lindh B. C., 2003; Lindh B. C., 2004), GDRCo populations are found within 45-65 year old stands. Floristic surveys in forest habitats are typically only conducted prior to commercial timber harvest activities, so plants may be present and undetected in stands younger than 45 years old as well. As GDRCo conducts more commercial thinning operations, an opportunity to discover C. laciniata in younger stands exists.

Research conducted in old-growth Douglas-fir forests in Oregon (Lindh B. C., 2003) indicates that forest herbs can be limited by soil moisture and nutrients as much or more than by low light penetration and that forest gaps are correlated with increased availability of these belowground resources. They observed that gaps in old-growth forests allowed proliferation of dense clonal patches of C. laciniata as well as investment in sexual reproduction resulting from increased flowering (Lindh B. C., 2003). On GDRCo, plants are generally found where herbaceous cover is low and there are gaps in the canopy. Halpern (1989) found combined herb and shrub cover to average only 14% which sounds fairly typical for GDRCo populations as well.

Microhabitats most associated with C. laciniata on GDRCo include streambanks and/or road cutbanks. At least 38% of GDRCo populations are located within riparian management zones (RMZs). Plants are often perched on cutbanks of old skid roads, particularly within RMZs. They are also found in association with rock outcrops. Plants within the forest interior are often located at the base of trees (particularly tanoak) where the leaf litter layer is well developed and herbaceous cover is very sparse. Some roadside populations have been found with very little overstory canopy cover due to the road opening itself, and occasionally upslope timber harvests that occurred prior to the placement of this species on the special plants list. In the case of the most exposed populations, darkened and/or discolored spots have been observed on older leaves, but otherwise plants show good vigor. Lindh (2008) observed large numbers of plants flowering in heavily thinned plots and those individuals often had small, chlorotic leaves likely due to the effects of intense sunlight.

A fair amount of research has been published on the response of this species to various timber harvest related impacts. Halpern (1989) found that residual species, such as C. laciniata recover gradually after clearcutting. The constancy of Coptis declined sharply following clearcutting and maintained that lower frequency in sample plots for the entire 21 years of study (Halpern, 1989). Gashwiler (1970) found Coptis continued to be extirpated from the study area for the duration of the 10-year study following clearcutting and broadcast burning. Halpern (1988) found that the resistance and resilience of the Coptis community were low for sites lightly burned following clearcutting while resistance was intermediate and resilience was high for sites that had no apparent soil disturbance and were not broadcast burned after clearcutting. Without a well-developed residual flora, long-term recovery on burned Coptis sites may require canopy closure to eliminate potential competitive invaders (Halpern, 1988). The association with skids roads and second growth forests belies the fact that it is possible for this species to re-establish at some point after clearcutting has occurred. Protection from broadcast burning following clearcutting appears to be a particularly important factor.

Populations in younger forests are limited by the absence of gaps and by slow recovery from declines that occur at the time of clearcut harvest (Halpern, 1989), therefore gaps created through thinning operations may have the potential for improving habitat quality in young stands. Studies (Lindh B. C., 2004) have shown that the species is more frequent in young managed stands (40 years old) that have been pre-commercially thinned versus those that have not been thinned. Pre-commercial thinning favors late-seral understory species at the expense of low shrubs and weedy species more so than commercial thinning. Flowering of C. laciniata increased in response to thinning, but was still well below that observed in nearby old-growth stands (Lindh, 2008). Increased flowering could lead to establishment of new individuals from seed and Lindh (2008) found that seeds sown in young forest plots not only germinated but commonly established and survived over a 5-year period. This suggests that maintaining populations within THPs should provide for recolonization of the site once the harvested areas become suitable habitat again.

The literature does not indicate that fungal associates are a limiting factor on managed landscapes. Coptis laciniata is not known to form ectomycorrizae, but most herbaceous species are associated with arbuscular mycorrhizal fungi (AMF) which are ubiquitous plant root symbionts. AMF tend to associate with multiple hosts and studies suggest that common forest management practices, such as clearcutting, have no adverse impact on AMF diversity (Opik, et al., 2008).

In 2013, an effort was made to visit many previously protected populations and to document the effectiveness of the applied mitigation. Applied mitigation measures fell into four main categories; 50- foot radius No-Harvest buffers, 25-foot radius No-Harvest buffers, avoidance within a riparian buffer or No protection provided (table 2). No attempt was made to visit equal numbers of the different treatments. Sites were primarily revisited based on their proximity to other work and the length of time that had passed since a visit had occurred. Even so, some conclusions can be drawn from the follow-up visits that have been conducted. Sites that are not provided any protection from direct impacts are highly likely to be extirpated. Sites that are provided protection from direct impacts, e.g. plants are not run over, burned, dug up or otherwise displaced or buried in slash, windthrow, road spoils, etc. are highly likely to survive.

Management recommendations: 1. Standard plant protection measures (PPMs): Coptis laciniata is shallow rooted and susceptible to direct impacts resulting from compaction by timber harvest operations. Plants are also at risk of direct impacts resulting from the deposition of logging slash, road spoils and/or other material

Page 14 of 56

on top of plants. Equipment should be excluded from protected areas or limited to existing, unoccupied road and skid trail surfaces within the protection area. Trees should be felled away from protected areas. Logging slash, road spoils and other materials should be excluded from protected areas. Protected areas downslope of timber harvest operations are at more risk of being intruded upon by these materials and the upslope side of protected areas may need to be enlarged to compensate for this potential threat. Windthrow may cause direct impacts to protected populations either from compaction, deposition (burial) or unanticipated increases in exposure that exceed what was expected to occur at the site. Canopy retention at particular sites may need to be adjusted to account for potential windthrow. Coptis laciniata is very susceptible to fire (Halpern, 1989); (Gashwiler, 1970) and protected areas should be protected from pile and broadcast burning. The size of the buffer and the degree of canopy retention should be adequate to minimize potential direct impacts and will vary by site. 2. Managed stands typically have higher tree densities and lower variation in tree size and canopy height than old-growth stands. Since this species is known to be associated with forest canopy gaps in old-growth (Lindh B. C., 2003) as well as 45-65 year old stands on GDRCo, pre- commercial and commercial thinning and selection in riparian management zones may increase habitat quality for this species by providing gaps. In these instances when the species is present, a 25-foot radius No-Harvest ELZ around the population surrounded by the site-specific prescribed amount of retention is likely to reduce adverse impacts to less than significant, provided the standard PPMs can also be applied.

GDRCo would like to work cooperatively with CDFW in 2014 to develop a property-wide consultation for Coptis that can be applied to future Timber Harvest Plans (THPs).

Cornus canadensis, bunchberry (COCAN) Status Report

A focused survey was conducted in Humboldt Coutny on GDRCo, within the vicinity of Snow Camp Lake and Roddiscraft Road with the goal of detecting additional populations of bunchberry. This species was added to the CRPR 2.2 in December of 2012. Prior to the rare plant ranking, the species had been noted as present in only five THPs surveys, and they were all in this area. Since the plant was not ranked as rare at the time of the surveys, the specific locations were not recorded. The botanist recalled one specific location and that site was revisited for a collection and assigned BotID#30487. This is currently the most northwestern documented population on GDRCo (T5N, R4E). Creeks within THPs where bunchberry was recorded as present were targeted for survey. Nine additional BotID#s were documented in the Maple Creek quad in 2013, and these are all T4N, R4E. The elevation range is 1238- 1306m. All ten BotID#s are associated with headwater streams to Pardee Creek including Cloney Gulch. Plants are found along streamsides and boggy areas. Plants are highly associated with late-decay large woody debris and are often found growing on top of highly decomposed, moist woody material. Douglas-fir (Pseudotsuga menziesii var. menziesii) was presnt at all sites and plants were often growing intermixed with salal (Gaultheria shallon). Other common associates include; Berberis nervosa, Blechnum spicant, Vancouveria hexandra, Vaccinium parvifolium and Senecio triangularis. Populations range in size from an estimated 50-10,000 “plants” and a total of approximately 15,000-20,000 across all ten sites. Surveyors recorded number of flowering sites since due to the rhizomatous nature it was difficult to discern number of individuals. This number is likely an overestimate of actual individuals. Most populations are located within THP units that have been harvested, but since they occur within the riparian management zones (RMZs) plants were still present and appeared to be thriving. Plants were found under moderate canopy cover and sometimes in the open. Some bleaching on the leaves was observed where there was no canopy at all, but plants were still flowering. The canopy cover would have been much higher prior to adjacent timber harvest. The creeks continue off of GDRCo to the northeast of these detections, where there is a contiguous tract of unharvested forestland. Additional populations may occur in this area.

Howell’s Montia, Montia howellii (CRPR 2.2) Salmon Creek Monitoring Update

Long-term Monitoring Strategy for montia in Salmon Creek as implemented in 2011-2014 Objectives: 1. Determine if the population of Montia howellii (MOHO) growing along the mainline Salmon Creek road system is increasing, decreasing or stable over time. Our metric will be number of plants per linear measurement. 2. Determine if presence or absence, or density of MOHO are correlated with habitat/management variables. 1. Percent cover of road surface type in five categories measured at the quadrat level: a. Rock b. Mostly rock with some fines c. ½ Rock, ½ Fines d. Mostly fines with some rock e. Fines (dirt, clay, sand) Observations over the last ten years and studies conducted by PALCO show that high quality habitat is compacted natural surfaced roads with high clay content. Rocking of roads leads to plant decline or extirpation. Over time rocked roads become suitable habitat again. 2. Percent cover of competing vegetation measured at the quadrat level – 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 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 abundance is highly correlated with specific habitat variables then manage for more of those)

The data from 2011-2013 was supplied to statisticians at West Inc. so they could conduct a power analysis. The goal was to determine if the sample size (110 permanent plots and 20 rotating plots per year) was adequate to determine trends in occupancy and density. The ‘Executive summary’ is included on the following page and the entire report is included as an appendix to this report. While the true year-to-year variation is likely to deviate from 0 (as estimated), potentially resulting in a significantly different outcome, the analysis clearly indicates that the current sample size is insufficient to detect a 1% or 4% annual trend in density. The power to detect a 1% or 4% annual trend in occupancy is high. Based on these results, the design of the yearly monitoring plan will be revised. Future monitoring effort will concentrate on detecting trends in occupancy. Road surface type and percent cover of competing vegetation will continue to be assessed as well. Trends in occupancy may be correlated with these data and help to inform what is driving the trend in either direction. These environmental factors can be modified with management. The mean cover of competing vegetation is found to have a significant negative effect on MOHO occupancy (p<0.0001) and simply grading the roads and pullouts at the appropriate time of year and on a regular basis may prove to be an effective management stratetgy. Some summary statistics are included below for reference.
