Book Description
Seasonally flooded land (ephemeral swamps and intermittent tributaries) located on the flood-plain of a west coast Vancouver Island stream (Carnation Creek) was examined for two winters. Seven distinct map units were identified by discriminant analysis, based on environmental and biotic factors. These seven map units were further grouped into three habitat units based on their ability to support over-wintering coho (Oncorhynchus kisufch ) and trout (Salmo gairdneri and S. clarki clarki). The use of these habitat units to identify salmonid off-stream winter habitat was shown to be valid for the watershed in which it was developed.

Book Description
What has happened to the salmon resource in the Pacific Northwest? Who is responsible and what can be done to reverse the decline in salmon populations? The responsibly falls on everyone involved - fishermen, resource managers and concerned citizens alike - to take the steps necessary to ensure that salmon populations make a full recovery. T

Book Description
In 1970, Carnation Creek, a small west coast watershed located on Vancouver Island, was selected for an interagency study to assess the effects of forest practices, including logging, prescribed burning, reforestation and herbicide use on salmonid production and to partition these effects from natural variability caused by factors such as climate, streamflow and nutrient availability. The project continues to the present, and was undertaken in 3 phases: pre-logging from 1970-75; active logging from 1976-81; and post-logging from 1982 to the present. This bibliography contains 147 articles and research papers produced by participants in the project. Article citations are listed alphabetically and include abstracts where available. In addition, manuscripts approved for publication to the date of this document are listed by contribution number.

Book Description
Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management. This book is the most recent major work on the ecology and management of Sitka spruce. The authors describe how this fascinating tree reproduces, grows, and functions in its natural geographic range. They discuss both the ecology of Sitka spruce and silvicultural questions such as original plantation spacing, juvenile spacing, and fertilization to accelerate the harvestability of second-growth coastal spruce stands. Sitka spruce derives its importance not only from its prominence as an international transportable genetic resource but also from its role in riparian systems and its biodiversity values. Here in North America's west coast rainforest, this magnificent tree illustrates the ecology of complex forest ecosystems and their cultural, wilderness, historic, and economic values.

Book Description
The proceedings, representing 17 years of results from the Carnation Creek watershed study, contains 17 technical papers about the physical and biological processes of the Carnation Creek ecosystem. After each session of technical papers, the proceedings contain commentaries from 6 panels of fish and forest agency staff and forest industry representatives. Finally, the verbatim questions and answers of the audience to each session of technical papers and panelists are also included so that the extent of understanding or uncertainties is preserved.
