Available in PDF, EPUB and Kindle. Book excerpt: "With continuing concern over declines in numbers of Black Ducks (Anas rubripes), efforts to monitor breeding populations of this species were renewed in the Atlantic Provinces, beginning in 1983. Helicopter surveys in spring were begun in New Brunswick in 1985, and extended to Nova Scotia and the island of Newfoundland in 1986. These pilot projects were proposed to continue for 5 years (through 1990). Observed breeding densities were highest in N.B. and lowest in Nfld., presumably reflecting a temperate to boreal/subarctic trend. Densities increased each year in N.B. but less consistently in the other provinces. The apparent increases may reflect general recovery of populations following harvest restrictions in the U.S.A. since 1982, but the trends are not (yet) conclusive"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Audubon Wildlife Report 1987 covers important events that highlighted wildlife conservation in 1986. This book is an attempt by the National Audubon Society to gather together much of the diverse data about federal wildlife-policy administration, providing a vast array of data on federal wildlife management and comparative tables on the budgeting process. This text also examines many federal wildlife programs, from the migratory bird protection program, which in a sense gave birth to the federal role in wildlife conservation, to the endangered species program, called as the most important wildlife conservation effort in the world. This publication is valuable to conservationists and individuals interested in federal and state wildlife management.
