Title: Problem Analysis: Old Growth and Ungulates of Northern Vancouver island

Year: 1982

Author(s): Ministry of Forests; Ministry of Environment

Type: Report (unpublished)

Description:
"Traditional timber harvest patterns on northern Vancouver Island have reduced the areas of old growth to the extent that deer and elk populations will be severely affected in a critical winter." Demand for both timber and wildlife "cannot be met to the degree that the proponents of each resource would prefer, and some reduction in wildlife recreation or timber harvesting is essential." These statements are included in the introduction to a one-year program, aimed at identifying various production levels of both timber and wildlife on northern Vancouver Island and released today from the ministries of Forests and Environment. The program proposal establishes terms of reference for the analysis and gives a comprehensive background to the difficult resource decisions which must soon be made between timber and wildlife on northern Vancouver Island. The procedure by which both resources will be analyzed and the various management options determine dis detailed, and a schedule for analysis and presentation of results is given.

Title: Predator-Ungulate Relationships In Second Growth Forests On Vancouver Island. Problem Analysis.

Year: 1982

Author(s): Ian Hatter

Type: Government document

Description:
The effects and influences of predation on ungulates are reviewed. Predation is a significant source of mortality and influences the distribution and habitat selection of native ungulates. Predation effects and influences on Vancouver Island deer and elk are reviewed and contrasted with those of the rest of North America. Predation on deer is particularly severe due to high wolf population densities and the probable additive effects of cougar and bear predation and human deer harvests. Wolves probably indluence seasonal movements and habitat selection of deer and elk but the available information is inconclusive. The potential effects and influences of wolf predation on ungulate populations in second growth forests is high. It presents a major confounding factor in interpreting deer and elk habitat utilization, animal condition, and population parameters. However, it is suggested that wolves should not be viewed as a confounding influence on intensive wildlife intensive forestry management but as an integral component of a managed predator-ungulate-habitat system. Specific problems and unknowns of predation are also identified. It is recommended that predation studies be implemented immediately.

Title: Coastal Waterfowl and Habitat Inventory Program: Summary Report Appendices

Year: 1982

Author(s): R. A. Hunter, Terrestrial Studies Branch, BC Ministry of Environment; L. E. Jones, Ducks Unlimited

Type: Report (unpublished)

Description:
Introduction: This document is one result of a three-year program designed to evaluate coastal wetlands of British Columbia. It is intended to provide a reconnaissance level assessment of the biological attributes of tidal wetlands and indicate social factors, developmental pressures and opportunity for rehabilitation and enhancement associated with them. To date, 403 wetlands have been assessed. Of these the majority are estuarine areas although selected sloughs, mudlats and freshwater coastal lowlands were included. Ratings for the various wetlands were determined by Rodget Hunter, Ken Summers and the following BC Fish and Wildlife Branch staff: Davies, Harding, Burgess, Cox, Swatcaviatcz, West, Beets, Edie, van Drimmellen. The primary purpose of this evaluation program was to indicate the relative importance of individual coastal wetlands of the province with respect to preservation, protection and enhancement. Potential uses of this information area: 1. land-use planners within various provincial government ministries 2. natural resource managers 3. agencies and private organizations involved in acquisition and/or protection and preservation of wetlands.

Title: Steamer Cover: Marine Biology Report

Year: 1980

Author(s): N. A. Sloan

Type: Report (unpublished)

Description:
On July 2, 1980 a marine biological survey of Steamer Cove, Flores Island consisting of a dive, 2 low tide beach seines, shore sampling and habitat vegetation mapping was completed. This small cove is fringed with a rugged bedrock-bouder shore which has occasional pocket gravel beaches with seagrass beds on their lower shores. Noteworthy environmental concerns are firstly the seagrass beds which are well known and monitored herring spawn deposition sites and secondly, but less important, the rich clam populations in the lower portion of the gravel beaches.

Title: Assessment of 1979 Herring Spawnings in the Meares Island Section of Clayoquot Sound, British Columbia

Year: 1979

Author(s): C.W. Haegele; D.C. Miller

Type: Report (published)

Description:
In the Meares Island section of Clayoquot SOund, herring spawn mainly on extensive beds of eelgrass. A diver survey of herring spawnings was conducted in 1979 to obtain the best possible estimate of egg deposition because estimates obtained from surface surveys seemed unrealistic. The survey showed that 3.7859 x 10(raised to the)12 eggs were deposited on 4.0028 x 10(raised to the)6 meters squared area. The large Elbow Bank had 50% of this spawn on 35% of the area. Sea grasses occupied 94% of the spawn area. Most of the spawn area was subtidal.

Title: The Long Beaches

Year: 1979

Author(s): Ian MacAskie

Type: Book

Description:
Back cover copy: Fogbound in the mountainous regions of a west coast inlet, and tossed in the treacherous and unpredictable waters of the Pacific Ocean, Ian MacAskie has written a compelling book based on these and other adventures. For many years, MacAskie, a marine researcher, explored the coasts of Alaska, British Columbia and Oregon in search of the Pacific fur seal. His research has increased our knowledge of the fur seals and of marine life in general. During his extensive travels he developed an interest in the history of the many remote coastal towns, villages and outposts he visited. His writing shows us that he is a keen observer of the people who inhabit these isolated ports: Indian, homesteader, whaler and fisherman who contribute to the history and unique personality of the Pacific northwest. From Indian tales, old manuscripts and diaries of early explorers, and the reminiscences of the inhabitants, he gives us a fresh and informative view of the history and locale.

Title: Winter Ecology of a Black Oystercatcher Population

Year: 1979

Author(s): E. B. Hartwick; W. Blaylock

Type: Newspaper Article

Description:
The movements and foraging of Black Oystercatchers were studied during winter. Many birds concentrated in mudflats during daytime where they fed on mussels (Mytilus edulis). The birds ignored other potential prey but had little impact on the mussel beds. More time was spent foraging in beds with higher densities of mussels and this behaviour is discussed in relation to a model of optimal foraging.

Title: Distribution and Movements of the Salamander Aneides ferreus (Cope, 1869) on Cleland Island, BC

Year: 1978

Author(s): Renata Jaremovic

Type: Academic Thesis

Description:
Very few studies have been carried out on the ecology of the Plethodontid salamander Aneides ferreus (Cope, 1869). The purpose of this study was to examine the distribution and movements of this species in relation to environmental variation on Cleland Island, BC. The microdistribution of Aneides is basically the result of behavioral strategies which tend to buffer variation in moisture and temperature. This study consisted of collecting mark-recapture data, monitoring micro- and macroclimatic conditions, and displacing individuals varying distances from their homes. Homing behavior and home site tenacity increase the probability of encoutering favorable conditions by increasing familiarity with a localized area. Under very dry conditions, salamanders may move into underground shelters where conditions are more favorable. Coiling and aggregation function to keep salamanders in one place during severe conditions by reducing evaporative surface area and thus the risk of desiccation. Behavioral strategies may vary with habitat type and salamander size. My data indicate either that home range size is smaller or that home site tenacity is greater in salamanders living in a wet habitat that those living in a dry habitat. Behavioral strategies may differ in large and small salamanders and probably relate strongly to physiological tolerance limits and dispersal capabilities. The seemingly flexible nature of salamander behavior keeps Aneides finely attuned to its microenvironment and thus allows this poikliotherm to modify its surroundings to a limited degree.

Title: Recovery Rate in Three Exploited Sea Urchin Populations from 1972 to 1977

Year: 1978

Author(s): P. A. Breen; B. E. Adkins; D. C. Miller

Type: Report (published)

Description:
Three sites near Tofino were examined in order to determine the rate of recovery of red sea urchin populations after harvesting. At all sites, harvesting had taken place in 1972. At two sites, the number now present is much less than the number that were removed in 1972. On the third site, the number removed is not known, but there are still large areas of empty sea urchin habitat. From size distributions observed in 1974, 1976, and 1977, we conclude that the number of juveniles recruited annually is only 5 to 10% of the present population. The effect of harvesting on the algal communities is variable, depending on the area and the intensity of harvesting. At one site, harvesting appears to have had no effect, while at the other two sites Nereocystis and Pterygophora have increased in abundance. The effect on other invertebrates cannot be determined.

Title: Predation on Nesting Glaucous-winged Gulls by River Otter

Year: 1977

Author(s): Robert G. Foottit; Robert W. Butler

Type: Journal Article

Description:
First paragraph: "Although ther eis evidence that birds constitute a small portion of the diet of the river otter, few cases of predation upon nesting seabirds have been recorded. During the summers of 1967, 1970, and 1973, direct and indirect evidence of predation on nesting Glaucous-winged Gulls (Larus glaucescens) was observed on Mitlenatch Island, British Columbia.
