2 Executive Summary Marbled Murrelets (Brachyramphus marmoratus) are a seabird that primarily nest in large coniferous trees of old-growth coastal forests and forage in adjacent marine environments. Populations are federally listed as Threatened in Canada and Blue-Listed in British Columbia as a result of nesting habitat loss from forest harvesting and threats to marine foraging and wintering areas. Consequently, the goal of this project was to examine the amount, distribution and configuration of suitable nesting habitat within the Campbell River watershed and surrounding BC Hydro footprint area and where possible, delineate Wildlife Habitat Area (WHA) proposals around patches of remaining suitable nesting habitat. Draft WHA polygon boundaries were delineated in ArcMap GIS software using a combination of coarse-scale low-level aerial survey data for Marbled Murrelets collected by Sue McDonald and Sally Leigh-Spencer in 2007, digital satellite images (SPOT5), TRIM (1:20,000) contours, roads and water features, harvest authorizations, and legally designated Old-growth Management Areas, Ungulate Winter Ranges, and WHAs for other species. Detailed low-level aerial surveys using standardized data collection protocol were used to confirm draft WHA habitat quality and polygon boundaries. Two flights were conducted (October 29 and November 3, 2010) over a total of four hours within the Sayward and Salmon Landscape Units of the Campbell River watershed and BC Hydro footprint area. During this time 13 draft WHA polygon boundaries were assessed which resulted in a final WHA candidate list consisting of six proposals five from the draft WHA list and one additional WHA candidate that was proposed in 2006 and these will be submitted to the regional WHA biologist for review and consultation. A total of ha of forests are included in the final WHA submission package which consists of 28.2 ha of Class 2 (High); ha of Class 3 (Moderate); 77.4 ha of Class 4 (Low); 9.5 ha of Class 5 (Very Low); and 0.5 ha of Class 6 (Nil) Marbled Murrelet breeding habitat quality. Overall, there is very little suitable nesting habitat for Marbled Murrelets remaining within the Campbell River watershed and BC Hydro footprint area and that which remains is primarily Class 3 (Moderate) and in patches <100 ha in size. Therefore, within this portion of the North and West Vancouver Island Conservation Region, where extensive forest harvesting has occurred and options for protecting suitable Marbled Murrelet breeding habitat are limited, habitat recruitment may need be considered an option to address the Canadian Marbled Murrelet Recovery Teams goals of protecting larger patch sizes, distributing habitat protection throughout the conservation region and for meeting their target of protecting 69% of 2002 population levels. 2

6 1. Introduction Marbled Murrelets (Brachyramphus marmoratus) are seabirds that nest almost exclusively in large coniferous trees of old-growth coastal forests. Populations are believed to be declining in many areas of their range in conjunction with habitat loss and fragmentation and threats within their marine environments (Burger 2002, Hull, in press). As of 2000, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) lists the Marbled Murrelet as Threatened (COSEWIC, in press) and it is provincially Blue-Listed by the Conservation Data Centre (BC Conservation Data Centre 2011). As such, Marbled Murrelets are recognized by the province of BC as requiring special management on Crown Lands to address the negative impacts of forest harvest activities and are included on the Category of Species at Risk under the Forest and Range Practices Act (FRPA; 2002). As a member of the Category of Species at Risk, Wildlife Habitat Areas (WHAs) are enabled as a habitat protection tool under the Government Action Regulation of FRPA; this has been the primary tool used on Vancouver Island to protect important nesting habitats for Marbled Murrelets. In addition, old-growth management areas (OGMAs), ungulate winter ranges (UWRs) and Parks and Protected Areas significantly contribute toward habitat protection efforts for Marbled Murrelets on Vancouver Island. Since the early 1950 s, BC Hydro has been active in the Campbell River watershed, installing and managing a series of hydro electric power facilities and diversions. Flooding of Lower Campbell Lake by the Ladore Dam is estimated to have resulted in the loss of approximately 138 ha of riparian habitats (BC Hydro 2000). In addition, altering stream channels through water diversions may have negatively impacted Marbled Murrelets through the loss of potential nesting habitat along riparian corridors. Marbled Murrelets commonly use riparian corridors as flyways to navigate and travel inland (up to 80 km; BC Ministry of Water, Land and Air Protection 2004) from marine foraging areas to nest sites. Some of the highest quality nesting habitat remaining for Marbled Murrelets is located along floodplains and riparian corridors, especially in watersheds like the Campbell River watershed that have an extensive forest harvest history. This project aims to compensate for these historical impacts by protecting some of the remaining suitable Marbled Murrelet nesting habitat in the Campbell River watershed and affected floodplain areas. 2. Goals and Objectives The primary goal of this project was to assess the location of remaining suitable nesting habitat for Marbled Murrelets on Provincial Forest Lands within the Campbell 6

7 River watershed and affected floodplain/diversion areas and to delineate proposed WHA boundaries for nesting habitat protection. Specific objectives were: a) To use coarse-scale low-level aerial reconnaissance survey data collected by Sally Leigh-Spencer and Sue McDonald in 2007 to delineate draft WHA polygons prior to surveys within the Sayward and Salmon Landscape Units; b) To conduct detailed low-level aerial reconnaissance survey via helicopter to verify the previous nesting habitat ratings used to delineate draft WHA polygons; c) To use information collected in (b) to refine WHA proposals for the Campbell River watershed and affected floodplain/diversion areas; and d) To submit WHA proposals to Ministry of Natural Resource Operations WHA biologist to initiate the formal consultation/negotiation process. 3. Study Area The Campbell River watershed drainage encompasses over 1,400 km 2 on eastcentral Vancouver Island. To increase water flow to the power facilities (John Hart, Ladore and Strathcona), BC Hydro established a network of diversions to the north (Salmon), south (Quinsam) and west (Heber) of the watershed (BC Hydro 2000). Land ownership within the Campbell River watershed study area consists of a mixture of Provincial Forest lands, private forest lands and Provincial Parks and Protected Areas. The Provincial Forest land base within the Campbell River watershed and BC hydro footprint area was the focus of Marbled Murrelet nesting habitat assessments for this project (Figure 1). The Campbell River watershed lies mainly within the Coastal Western Hemlock (CWH) and Mountain Hemlock (MH) biogeoclimatic zones. The study area is situated within the CWHxm1, CWHxm2 and CWHmm2 subzones of CWH biogeoclimatic zone (Green and Klinka 1994). Forests are comprised predominantly of second growth Douglas-fir (Pseudotsuga menziesii), western hemlock (Tsuga heterophylla) and western redcedar (Thuja plicata) that were established after a large forest fire swept through the area in 1938 and subsequent forest harvest occurred. Some remnant patches of old-growth forests remain along riparian corridors, floodplains and scattered throughout the study area. 4. Methods Pre-flight Planning and Draft WHA Boundary Delineation Using ArcMap vs GIS software, coarse-scale low-level aerial survey data for Marbled Murrelets collected over multiple landscape units in 2007 (McDonald and 7

8 Spencer 2009), was used to guide draft WHA boundary delineation. As well, digital satellite images (SPOT5) along with TRIM (1:20,000) contours, roads and water features, harvest authorizations, and legally designated OGMAs, UWRs, and WHAs for other species were considered in draft WHA polygon boundary design. Other factors considered when WHAs were delineated using GIS include: polygons with primarily very high, high, and moderately-ranked low-level survey data; size and configuration to minimize hard edge influences as well as distribution throughout the study area (BC Ministry of Water, Land and Air Protection 2004). For each WHA polygon, I generated a waypoint to load into GPS units to aid with pilot navigation and I generated GIS shapefiles for polygons and these were loaded into Oziexplorer GPS mapping software (vs k). Paper maps for each draft WHA polygon were printed out and accompanied observers during flights to assist with boundary revisions. Low-level Aerial Surveys Although low-level aerial survey data for Marbled Murrelets were collected within the study area in 2007, these were coarse-scale surveys and so it is necessary to conduct detailed habitat assessments that focus on draft WHA proposals to confirm habitat quality and refine WHA polygon boundaries (Waterhouse et al. 2009). Low-level aerial surveys and habitat rankings were conducted using standardized protocol described by Burger (2004). Two experienced observers and an experienced piliot were present during surveys which were conducted using an A-star helicopter in weather conditions where habitat characteristics were visible and easily ranked. A laptop computer with Oziexplorer GPS mapping software and geo-referenced polygons for draft WHAs was connected to a hand-held GPS unit. These tools were used to navigate to each location and to thoroughly cover each polygon while tracking real-time flight paths. For each polygon, observers discussed the habitat quality and one observer filled out the standardized data form for conducting low-level aerial surveys (Appendix III; Burger 2004). Habitat quality was ranked using a six-class provincial rating standard (1 = very high; 2 = high; 3 = moderate; 4 = low; 5 = very low; 6 = nil). The overall habitat quality rank is a combined rating which reflects a number of habitat attributes important for Marbled Murrelet nesting. These include: 1) the percentage of all trees that are large (>28.4 m); 2) the percentage of canopy and emergent trees with one or more platforms (> 15 cm in diameter); 3) canopy closure; 4) vertical canopy complexity; 5) topographic complexity; 6) estimated age class of the forest stand; and 7) leading tree species (and if these are on slopes or valley bottoms). See Burger (2004) for more detailed descriptions of each habitat attribute listed above. Additional waypoints and refinements on paper maps were used to record boundary adjustments to proposed WHA polygons during flights. 8

10 Post-flight Data Processing and Proposed WHA Boundary Refinement Following low-level aerial survey flights, draft WHA polygons were either removed from the proposal or boundaries were refined, as necessary, using ArcMap GIS software. To support WHA proposals a WHA data form multiple proposals was completed to accompany spatial polygons (Appendix V) and these were submitted to the regional Ministry of Natural Resource Operations WHA biologist in Nanaimo to review and initiate consultation. 5. Results Detailed low-level aerial assessment data were collected by two qualified biologists using an A-star helicopter within the Sayward and Salmon Landscape Units of the Campbell River watershed and BC Hydro footprint area. Two separate flights were conducted (October 29 and November 3, 2010) due to poor weather encountered during the first flight, and flights spanned a total of four hours. During this time 13 draft WHA polygons were assessed using detailed low-level surveys (Figure 2) which resulted in a final WHA candidate list consisting of five proposals (Figure 3). One additional WHA candidate that was proposed in 2006 will be submitted with this package (1-203) to the regional WHA biologist for review and consultation. Overall, ha are included in this WHA proposal package (Table 1). The average WHA polygon size for the final proposal including six polygons is 67.6 ± 26.3 ha (SD). This total includes the following amounts of habitat by quality as assessed using coarse low-level aerial survey data collected by Sue McDonald and Sally Leigh- Spencer in 2007: 28.2 ha of Class 2 (High); ha of Class 3 (Moderate); 77.4 ha of Class 4 (Low); 9.5 ha of Class 5 (Very Low); and 0.5 ha of Class 6 (Nil). However, habitat ratings from coarse low-level survey data were overall one to two quality classes higher than what we observed during detailed low-level aerial assessments (Table 2). Therefore of the 13 WHA candidates assessed, eight were not included in the final proposal list because their ratings decreased from suitable (mostly Class 3 rank) to unsuitable (Class 4 or 5). Five of the six final WHA candidates are co-located, to some extent, with legally designated OGMAs and one with a legally designated UWR. 10

Number of polygons in each habitat quality class (coarse-scale) Detailed Very High High Moderate Low Very Low Surveys Very High High Moderate Low Very Low Discussion Overall, there is very little suitable nesting habitat for Marbled Murrelets remaining within the Campbell River watershed and BC Hydro footprint area. The extensive forest fire in 1938 and subsequent forest harvesting that occurred over the following decades has significantly reduced options for Marbled Murrelet nesting habitat protection using WHAs. Therefore, the six WHA polygons that I will propose as a result of this project will assist with habitat protection within the Marbled Murrelet Recovery Team s West and North Vancouver Island Conservation Region but there is still a significant gap in meeting the Recovery Team s goal for this Conservation Region to maintain at least 69% of the 2002 population of Marbled Murrelets (Canadian Marbled Murrelet Recovery Team 2003). Currently, only 19% of suitable Marbled Murrelet nesting habitat, as predicted by the Canadian Marbled Murrelet Recovery Team s habitat suitability model, is protected within the West and North Vancouver Island Conservation Region (Mather et al. 2010). 11

14 As well, the habitat quality and size of suitable habitat polygons currently available for Marbled Murrelet nesting habitat protection within this study area is mostly limited to moderate quality habitat within patches that are <200 ha in size. Although there remains some debate regarding optimal patch sizes for Marbled Murrelet breeding habitat protection, research on Vancouver Island conducted by Malt and Lank (2007) suggests smaller habitat patches with hard edges (recent clearcuts) increases the likelihood of Marbled Murrelet nest predation by corvids. The Marbled Murrelet Recovery Team indicates edge effects are greatest when habitat patches are surrounded by hard edges and are <100 ha in size (Canadian Marbled Murrelet Recovery Team 2003). Therefore, the Marbled Murrelet Recovery Team and the Identified Wildlife species account for Marbled Murrelet (British Columbia Ministry of Water, Land and Air Protection 2004) recommend maintaining a proportional mix of patch sizes representing large (>200 ha), medium ( ha) and small (<50 ha) patches within managed forests. Proposed WHAs included two polygons in the small size category and four in the medium size category; there were no draft WHA candidates within the large size category within the study area. Habitat quality assessments conducted using different methodologies or even similar methodologies but at different spatial scales can yield different results (Mather et al. 2010, Donald et al. 2010, Waterhouse et al. 2010, Burger et al. 2009). Three main methods are used to assess Marbled Murrelet nesting habitat quality: 1) the Canadian Marbled Murrelet Recovery Team s habitat suitability model that uses tree height, tree age, elevation, and distance from salt water attributes to predict forests as suitable or not suitable (Chatwin and Mather 2007); 2) air photo interpretation mapping that uses a standardized six class rating scheme (Burger 2004); and 3) low-level aerial surveys that uses a standardized six class rating scheme (Burger 2004). Low-level aerial surveys are the only method that ranks habitat quality through direct observations of forest attributes and therefore, this is a preferred method that can be used to verify the other two methods (Waterhouse et al. 2010), especially when using information to delineate WHA boundaries. Unfortunately, low-level aerial surveys can be conducted at different scales of observation and this may result in different habitat classifications for the same geographic area. For example, within this study area, Sue McDonald and Sally Leigh-Spencer conducted coarse-scale low-level aerial assessments in 2007 whereby entire landscape units and forest management tenures were assessed and so some smaller polygons only received a single pass for assessment (McDonald and Leigh-Spencer 2009). Our survey methods utilized these coarse-scale low-level aerial survey data to delineate draft WHA polygons but our detailed assessments of each polygon suggested that coarse-scale surveys consistently ranked habitat quality as being better than when we assessed it. Typically, we expect coarsescale low-level aerial surveys to under represent habitat quality because small patches of higher quality habitat may be missed within larger polygons of poorer habitat quality (Donald et al. 2010). Therefore, it is unclear why we observed this trend but it may be due to observer differences or smaller patches of poorer quality habitat within moderate-quality polygons being missed. Because there was mainly moderate quality habitat available within this study area for inclusion in WHAs, our observations primarily resulted in draft WHAs being dropped from our final proposal package because habitat quality ranked as moderate during coarse-scale surveys was ranked as low or very low during our detailed surveys. 14

15 7. Recommendations Based on the results from the detailed low-level aerial survey data collected during this project, I recommend that where financially possible, detailed low-level aerial surveys occur to verify the habitat quality of WHA proposals that are based on coarse-scale lowlevel aerial assessments. In this study area, several WHA polygons would have been proposed that contained primarily unsuitable habitat types without the detailed assessments. Furthermore, within this portion of the North and West Vancouver Island Conservation Region, where extensive forest harvesting has occurred and options for protecting suitable Marbled Murrelet breeding habitat are limited, habitat recruitment may be considered an option to address the Canadian Marbled Murrelet Recovery Teams goals of protecting larger patch sizes, distributing habitat protection throughout the conservation region and for meeting their target of 69% of 2002 population levels (Canadian Marbled Murrelet Recovery Team 2003). Currently, habitat recruitment of appropriate second-growth forests is considered to be a long-term priority for Marbled Murrelet recovery, after suitable habitats have been protected, and when we move towards this strategy, methodologies for determining which habitat types will recruit suitable habitat characteristics (such as mossy platforms), will need to be refined. 8.
