This plan has been prepared to define recovery actions necessary to protect and recover the Nova Scotia population of Blanding's turtle. The introduction presents background on the conservation status of the species and the biology of Blanding's turtle in Nova Scotia. Section 2 discusses factors affecting the vulnerability of the species, the role of the turtle in the Nova Scotia Atlantic interior ecosystem, and the recovery potential of the species. Section 3 outlines the recovery plan, including goals & objectives, strategies, and a sequence of actions. Additional information is provided for each step of the plan: determination of habitat requirements and availability, implementation of habitat protection, clarifying understanding of the turtle's life history, stabilizing population age structure through increased recruitment, investigating population genetics, and providing data storage and access. The final section contains a plan implementation schedule.

The Harlequin Duck (Histrionicus histrionicus) is a small sea duck, which travels inland to breed on fresh water streams. Harlequins breed in western North America from Alaska and the Yukon south through western Montana to California (Harlequin Duck Working Group 1993); in eastern North America, they breed from Baffin Island south to eastern Quebec and Labrador (Goudie 1993). In the Palaearctic, they breed in Iceland, Greenland and Siberia (A.O.U. 1983). Approximately 110-150 pairs of Harlequins currently breed in Montana (Reichel and Genter 1994), with most located in the following areas: 1) tributaries of the lower Clark Fork River; 2) tributaries of the North, Middle, and South forks of the Flathead river; 3) streams coming off the east front of the Rocky Mountains; and 4) the boulder River (Miller 1988, 1989, Kerr 1989, Carlson 1990, Fairman And Miller 1990, Diamond and Finnegan 1992,1993). During the breeding season, Harlequins are found along fast mountain streams (Bengston 1966). In many areas, harlequins use streams with dense timber or shrubs on the banks (Cassirer and Groves 1990), but they are also found in relatively open streams along the east slope of the Rocky Mountains, Montana (Markum and Genter 1990, Diamond and Finnegan 1992), and the arctic tundra (Bengston 1972). In Idaho, 90% of observations occurred near old growth or mature timber stands (Cassirer and Groves 1990). Mid-stream rocks, logs, islands, or stream-side gravel bars serve as safe loafing sites and appear to be important habitat components. Most of the ducks arrive on their inland breeding areas in mid-April to early May; unmated males typically arrive before pairs (Kuchel 1977). The females and young remain on the streams until August or early September. This chronology is influenced by elevation and by the timing of spring runoff, it may vary up to several weeks between years. The U.S. Forest Service, Region 1, lists the Harlequin Duck as Sensitive (Reel et al 1989). The species is listed as a Species of Concern by the Montana (Montana Natural Heritage Program 1994) and Idaho (Idaho Conservation Data Center 1994) Natural Heritage Programs. The eastern and western populations are both listed under Category 2 as candidates for protection under the Endangered Species Act by the U.S. Fish and Wildlife Service (U.S. Department of Interior 1991). The Montana Natural Heritage Program began surveying Harlequin Ducks in 1988. The survey data gave rise to questions involving site fidelity, productivity and mortality. We began individually marking Harlequins to a limited extent in 1991; through 1995, a total of 249 Harlequins were marked on 9 streams, representing the largest population of marked Harlequins from breeding streams. Birds marked in Montana have subsequently been captured and observed on the coasts of Oregon, Washington and British Columbia, with most reports coming from Vancouver Island. During that time, we observed 20 previously marked adults returning to Montana streams.

Voisey's Bay Nickel Company proposes to mine nickel and some other metals at a site located 35 kilometres south of Nain in northern Labrador. This report presents findings of a federal, provincial, and Inuit/Innu panel that reviewed the environmental, social, and economic impacts of the proposed mine project. The introductory sections discuss the project review process, the overall nature of the project and its effect on sustainable development, the need for the project (with reference to nickel markets), and mine resource stewardship. Subsequent sections cover effects on Native land claims, air quality, management of tailings and other waste, contaminants in the environment, freshwater fish and fish habitat, marine environment and mammals, shipping, terrestrial environment and wildlife, birds, Aboriginal land use and historical resources, employment and business opportunities, family and community life, public services, and environmental management (including reclamation and monitoring). Recommendations made throughout the report are also listed in the final section.

"Politics of the wild details the 353 species at risk in Canada and considers both the intrinsic and the instrumental reasons for protecting biological diversity, with chapters examining the need for habitat protection, terrestrial protected areas such as national parks, marine species at risk, and the various legislative and interest group attempts to preserve biodiversity. Public policy on endangered species is considered from both historical and comparative perspectives, as is Canada's role in establishing international agreements--and the government's failure, in recent years, to meet the obligations that they entail."--Cover.
