Title: Amphibians and Fish Within Wetlands of the Clayoquot Biosphere Reserve Region 2012-13

Year: 2014

Author(s): Barbara Beasley

Type: Report (unpublished)

Description:
We gathered information about the distribution of two species of aquatic-breeding amphibians. Red-legged frogs (Rana aurora) and Northwestern Salamanders (Ambystoma gracile) relative to the presence of native species of fish, in particular Coho (Oncorhynchus kisutch), Cutthroat Trout (Oncorhynchus clarki clarki) and Three-spined Stickleback (Gasterosteus aculeatus) in natural and restored/created freshwater wetland habitats. The Red-legged Frog and Cutthroad Trout are blue-listed species in British Columbia and the former is also federally listed as a Species of Special Concern. Our ultimate aim is to gather information that will help us learn how to manage and restore wetlands in ways that provide productive habitat for both fish and amphibians. We focused our project at wetlands within and adjacent to the Lost Shoe watershed on the Kennedy Flats near Ucluelet, BC. Many fish streams in the Kennedy Flats damaged by poor logging practices in the past are undergoing restoration. Improving fish access to Swan Lake, a 4-ha wetland that currently has no fish, has been a controversial project because Swan Lake has one of the highest counts of breeding Red-legged Frogs recorded in BC. It has been suggested that restoration of fish access to Swan Lake will cause a reduction in the breeding population of Red-legged Frogs and other amphibian species, but the magnitude of the reduction is unknown. Our objectives were to (1) collect baseline data on the abundance of egg masses and larvae of Red-legged Frogs and Northwestern Ssalamanders at Swan Lake to compare to abundance patterns after fish return in the future, (2) compare the relative abundance of egg masses and larvae of Red-legged Frog and other amphibians in wetlands with and without fish, and (3) document water quality variables that could limit the abundance or duration of fish presence in Swan Lake and other wetlands.

Title: Kennedy Watershed Restoration Project

Year: 2014

Author(s): Jessica Hutchinson; Lily Burke; Warren Warttig

Type: Report (unpublished)

Description:
The Kennedy Flats Watershed is located in Clayoquot Sound, on the west coast of Vancouver Island, in British Columbia, Canada. Much of the watershed was logged between 1950 and 1980. Logging practices of the time were not designed to protect wildlife or fish habitat, and as a result many of the streams in the area have reduced fish access, poor water quality, and lack the necessary characteristics to support healthy and diverse wildlife populations. Central Westcoast Forest Society (CWFS) initiated the Kennedy Watershed Restoration Project in 1994 to address the conditions affecting wildlife and wild salmon productivity. Since that time, CWFS restoration crews have been working to restore the hydrological and ecological functions of the watershed. ...

Title: Does Sex Matter? Temporal and Spatial Patterns of Cougar-Human Conflict in British Columbia

Year: 2013

Author(s): K. J. Teichman; B. Cristescu; S.E. Nielsen

Type: Journal Article

Description:
Wildlife-human conflicts occur wherever large carnivores overlap human inhabited areas. Conflict mitigation can be facilitated by understanding long-term dynamics and examining sex-structured conflict patterns. Predicting areas with high probability of conflict helps focus management strategies in order to proactively decrease carnivore mortality. We investigated the importance of cougar (Puma concolor) habitat, human landscape characteristics and the combination of habitat and human features on the temporal and spatial patterns of cougar-human conflicts in British Columbia. Conficts (n=1,727; 1978-2007) involved similar numbers of male and female cougars with conflict rate decreasing over the past decade. Conflicts were concentrated within the southern part of the province with the most conflicts per unit area occurring on Vancouver island. For both sexes, the most supported spatial models for the most recent (1998-2007) conflicts contained both human and habitat variables. Conflicts were more likely to occur close to roads, at intermediate elevations and far from the northern edge of the cougar distribution range in British Columbia. Male cougar conflicts were more likely to occur in areas of intermediate human density. Unlike cougar conflicts in other regions, cattle density was not a signficiant predictor of conflict location. With human populations expanding, conflicts are expected to increase. Conservation tools, such as the maps predicting conflict hotspots from this study, can help focus management efforts to decrease carnivore-human conflict.

Title: The persistence and stability of fish assemblages within eelgrass meadows (Zostera marina) on the Pacific coast of Canada

Year: 2013

Author(s): Cliff Robinson, Marine Protected Areas Research Group, UVic; Jennifer Yakimishyn, Pacific Rim National Parks Reserve

Type: Journal Article

Description:
The persistence and stability of fish assemblages found in 34 eelgrass (Zostera marina) meadows along the British Columbia coast was examined from 2004 to 2011. Assemblage persistence (nontrending species composition) and assemblage stability (constancy in abundance over time) were assessed using a time-lag regression method that tests for temporal turnover within short time series. Overall, 85 percent of the fish assemblages persisted, and 80 percent of the assemblages exhibited stability in abundance over the 8-year study. Environmental conditions in 33 of 34 meadows did not change substantially over the 8 years, and the low interannual variability may have contributed to the high persistence and stability of the fish assemblages. The lack of temporal turnover in relatively undisturbed eelgrass fish assemblage properties is a critical element for effective monitoring of coastal ecosystem integrity.

Title: Eelgrass and fish assemblage properties as indicators of biotic integrity in the Clayoquot Sound Biosphere Reserve.

Year: 2012

Author(s): Cliff Robinson; Jennifer Yakimishyn

Type: Report (unpublished)

Description:
The conservation of biological diversity within the Clayoquot Sound Biosphere Reserve (CSBR) is a key element needed to drive the production of ecosystem services for long-term sustainable use by local communities. The main objective of this study was to develop a simple framework for the Clayoquot Biosphere Trust (CBT) to assess fish diversity in eelgrass meadows using a multimetric approach. Eelgrass (Zostera marina) was chosen as a focal habitat because it is globally considered to be one of the most ecologically important coastal habitats providing a variety of commercially, recreational and ecologically important fish species with outstanding feeding and growing potential, and shelter from many piscivorous and avian predators. This study evaluated three eelgrass metrics (water column nitrate concentration, leaf area index, and epiphyte load) and 12 metrics describing fish assemblage species composition, assemblage abundance, proportion of indicator species groups (e.g., fishery species), nursery function, and trophic function. The abundance of one resident iconic species, the Bay pipefish, was also considered. Metric values for eelgrass and fish assemblages were determined for 6 meadows sampled by the CBT in 2008 and 2011, and compared to metric values derived for 22 meadows sampled in Clayoquot Sound (CS) by Pacific Rim National Park Reserve from 2004-2012. The framework allows for evaluation of eelgrass and fish assemblage metrics by comparing CBT meadow values to the distribution of natural variability observed in metric values from 114 observations made elsewhere in Clayouqot Sound. If 3of 12 fish metrics (one quarter) for each CBT meadow fell below the 10th percentile of the 114 CS observations then potential impairment in the fish assemblage was considered. Overall, two major conclusions were made from this analysis and can contribute to CBT vital signs monitoring. First as of 2011, the 6 CBT meadows appear healthy because none of the eelgrass metric values were found near the thresholds for potential impairment. Second, five out of six fish assemblages appeared in good condition in 2011, but CBT Meadow Bawden Bay had 3 out of 12 fish metrics fall below threshold values and it should be re-sampled to confirm for potential impairment. Overall, the limited eelgrass sampling by CBT has demonstrated that meadows are healthy and likely functioning within natural variability. Two major recommendations were made: 1) continue to sample the 6 CBT meadows to build a long term understanding of temporal variability in fish diversity, and 2) map eelgrass distribution and continue to sample fish assemblages in CSBR to better describe and understand the spatial variability in meadow structure and function. Overall, the framework presented will aid the CBT in monitoring the vital signs of fish diversity in ecologically important eelgrass ecosystems.

Title: Habitat heterogeneity in eelgrass fish assemblage diversity and turnover

Year: 2011

Author(s): Clifford Robinson; Jennifer Yakimishyn; Philip Dearden

Type: Journal Article

Description:
Maintaining habitat diveristy and heterogeneity are key ecological elements of marine spatial planning. It is often assumed that patches of the same habitat harbour similar biological diversity. However, if habitat heterogeneity is high then the efficacy of habitats as surrogates of species diversity is weakened."

Title: Wetland surveys for breeding amphibians within the Clayoquot Biosphere Reserve Region 2008-2011.

Year: 2011

Author(s): Barbara A. Beasley

Type: Report (unpublished)

Description:
The goal of this project is to protect the integrity of local wetland ecosystems within the Clayoquot Biosphere Reserve Region over time. These habitats provide a variety of ecological services and support amphibian species listed as being "at risk" within Canada. This project will determine the local status of Red-legged Frogs (Rana aurora) and Western Toads (Bufo boreas) and use fluctuations in their populations, as well as Northwestern Salamanders (Ambystoma gracile), as barometers of the health of our wetland ecosystems. Amphibians are good indicators of ecosystem intergrity becuase they are particularly sensitive to changes in water quality and quantity, and they are an integral part of the food webs within wetlands and surrounding forests. Habitat destruction, highway traffic, pollution, introduced Bullfrogs, and disease may reduce amphians populations. Sharing information on how these threats influence the status of local populations will help promote stewardship of wetland ecosystems in the region. The project objectives area: 1. To survey freshwater wetlands and monitor the breeding populations of two species at risk, the Red-legged Frog, the Western Toad, and a third species, the Northwestern Salamander, in and around Ucluelet, Tofino, and the Long Beach Unit of Pacific Rim National Park Resrve (PRNPR). 2. To describe vegetation, hydrology and surrounding conditions, of the wetlands. 3. To do surveillance for introduced Bullfrogs. 4. To provide opportunities for local youth and adults to learn skills involved in surveying amphibians and doing Bullfrog surveillance at wetlands. 5. To share information with local planners, government agencies, community leaders, landowners, and the general public in an effort to help maintain the ecological value of local wetlands, and the species at risk they support. ...
