Title: Tofino Mudflats Wildlife Management Area Management Plan

Year: 2002

Author(s): M. Eggen; S. Diggon; A. Mason

Type: Report (unpublished)

Description:
A management plan for the Tofino Mudflats Wildlife Management Area (WMA) was initiated by the BC Ministry of Water, Land and Air Protection (MWLAP). The main objectives of the management plan were to provide a current ecological and human use description, an integrated management strategy that strives to protect the natural resources of the WMA, and a plan for a wildlife viewing network. Current information on ecological and human use was collected from existing documented sources and through consultations with the public, local governments and organizations. A consultation process was initiated in order to gather and incorporate community input in planning for management of the WMA. The Tofino Mudflats WMA is defined by its jurisdictional boundaries; however, it is ecologically connected with surrounding marine and terrestrial environments at local, regional and international levels. These connects are reflected in the management plan.

Title: Habitat, population structure and energy value of benthis amphipods and implications for gray whale foraging in Clayoquot Sound, British Columbia.

Year: 2001

Author(s): Erin Hana Carruthers

Type: Academic Thesis

Description:
The majority of Eastern Pacific gray whales ('Eschrichtius robustus ')migrate from southern breeding grounds to the Bering and Chukchi seas where they feed principally on benthic amphipods throughout the summer. However, increasing numbers are now summering in locales along the coast locales along the coast of Oregon, Washington and British Columbia. Clayoquot Sound on the west coast of Vancouver Island is one area where gray whales are known to summer in relatively large numbers. M.Sc. Thesis, Queen's University

Title: Restoration Plans: Kennedy Flats

Year: 2001

Author(s): Warren Warttig, Interfor; Dave Clough, D.R. CLough Consulting Ltd.; Mike Leslie, Mike Leslie Consulting

Type: Report (unpublished)

Description:
Executive Summary: Restoration plans are developed to aid in the recovery of both terrestrial and aquatic habitats. In order for a restoration plan to be successful all relevant factors must be considered. The most common factor associated with declines of anadromous salmonids is habitat degradation, however a number of other factors play a key role. Many factors, such as habitat loss and degradation, over exploitation in sport and commercial fisheries, global warming and variable ocean conditions, are responsible to a varying degree for the depressed status of salmonids. Restoration of upslope and fluvial processes that create and maintain habitats must be integratl components of any recovery program. This report is limited to the unhealthy ecosystems of upslope, road, stream function, and riparian areas, and does not address fish harvest management, global warming, or variable ocean conditions. Stable landscape units outside the riparian zone are also not addressed in this report, but their status may have minor implications for stream ecosystems. Salmon have evolved to adapt to a series of natural impacts, therefore timber harvesting plans should be encouraged, where possible, to mimic the natural disturbance regimes. Examples of natural disturbance regimes could be: blow down (windstorms cause major natural disturbance to forest in Clayoquot Sound), wildfires, encouraging uneven aged standes to develop from even aged second growth, etc. The Clayoquot Sound Scientific Panel (CSSP) recommendations call for salmon recovery efforts to be based on restoring and conserving ecosystems, rather than simply restoring hte instream habitat attributes. Thi sis important, as relationships between habitat conditions and individual salmonid response have been well established within the habitat unit, stream reach and to the watershed unit as well.

Title: The Effects of Variable Removal Levels of the Sea Urchin, Strongylocentrotus faciscanus, on near-shore rocky communities in the traditional territory of the Hesquiat First Nation

Year: 2001

Author(s): Robert C. Mooney, California State Polytechnic University

Type: Academic Thesis

Description:
The shallow subtidal regions near Hot Springs Cove, Vancouver Isalnd, British Columbia are characterized by large rocky areas dominated by the red sea urchin, Strongylocentrotus franciscanus. S. franciscanus were removed at three sites with four levels of urchin removal per site. Manipulations of urchin density were maintained throughout the experiment and monitored seasonally for two seasons pre-treatment and seven seasons post-treatment. The manipulations resulted in increased gonad indices of remaining red sea urchins and caused the conversion of urchin dominated subtidal regions into kelp dominated communities with greater fish abundance. As well, a feeding experiment illustrated that the depressed gonad indices of field-collected urchins resulted from limited food resources in areas of high urchin density. The removal of sea urchins at all levels results in a rapid increase in the presence of laminarialean algal species (kelps). Study plots where all urchins were removed developed a dense understory and seasonal canopy of kelps with little bare rock remaining. Intermediate levels of removal resulted in a mosaic of smaller urchin-dominated and kelp-dominated patches. Control plots tended to maintain the urchin-dominated barrens-state throughout the study period. Sea urchins that were fed M. intergrifolia during the feeding experiment showed 2.9 and 2.4 times greater gonadal development by weight than urchins collected from the field before and after the feeding trial, respectively. These results suggest that food limitation is an important factor in the gonadal development of this urchin population. Findings suggest that with supplemental feeding, the resource base of sea urchins could be expanded to include barren habitats. The removal of S. franciscanus at all levels results in an increase in the fecundity (measured as gonad index) for the sea urchins that remained, as well as for the urchins that reinvaded the total removal plots. All study plots showed an increase in gonad index over time, but the increase in gonad index was statistically greater for urchins in removal plots versus the control plots. The results indicate that small isolated urchin removals can have measurable effects on the fishery value of nearby urchins. Of the seven fish species monitored, pile perch, striped seaperch, kelp perch and black rockfish were most associated with kelp forest habitat. Kelp greenling, lingcod and copper rockfish showed no association with kelp forest habitat. The experimental approach taken indicates that sea urchin removal, and subsequent kelp growth, determined relative fish abundance. High densities of S. franciscanus appear to be responsible for the absence of kelp forest habitat in the region, the depressed fecundity (gonad index) of S. franciscanus, and the abundance of some fish species. The effect of urchin removal is discussed in regards to the implications for ecological theory as well as sea urchin fisheries management.

Title: Foraging patterns of gray whales in central Clayoquot Sound, British Columbia, Canada

Year: 2001

Author(s): Jason S. Dunham, Whale Research Laboratory, UVic; David A. Duffus, Whale Research Laboratory, UVic

Type: Journal Article

Description:
Gray whales, Eschrichtius robustus, forage in parts of Clayoquot Sound on several prey species in different habitats. Between June and September in 1996 and 1997 we carried out analyses of the density, biomass and other measures of their primary prey species, and of whales' movement patterns in response to prey characteristics. The prey base consists of hyper-benthic mysids (family Mysidae), pelagic porcelain crab larvae (4 spp. of family Porcellanidae), benthic amphids (family Ampeliscidae) and benthic ghost shrimp, Callianassa californiensis. Whales foraged primarily for mysids, switch to porcelain crab larvae in August, and then to amphipods even later in teh season when these organisms increased in body size. In 1997, whales rapidly switched from feeding on planktonic to benthic prey during mid-August. Sampling indicated low numbers of mysids and crab larvae at that time. Selection of amphipod prey was based on high biomass and a high proportion of individuals less than 6 mm in length. In parts of the study area gray whales did not return to forage on benthic amphipods when this size criteria was not met. A single whale departed from a ghost shrimp feeding ground because its search time for food was long, it achieved only a low biomass removal rate, and it was not able to find sufficient food each day. We show that gray whales are dynamic and selective foragers that switch prey and foraging tactics rapidly to take advantage of short-term availability of energy.
