These ecosystems support some demonstrates that the Boreal Forest Region is vital to the of the greatest abundance of wildlife on the continent, abundance of bird life in the U. S. and Canada, and also including massive caribou herds, intact predator-prey contributes in a significant way to the abundance of birds in systems with healthy populations of top predators like Mexico, the Caribbean, and [...] In fact, the Boreal Forest Region represents 26% of the land area of the The study's findings demonstrate that the Boreal Forest U. S. and Canada - yet this report shows that it supports Region is critical to the well-being of many species of nearly 50% of North America's bird species. [...] Thirty-five of Approximately 30% of all shorebirds (7 million) and 30% of 44 waterfowl species (80%) in the U. S. or Canada breed all landbirds (1-3 billion) that breed in the U.

[...] For waterfowl in particular, a more accurate estimate of the proportion of continental 1) The first is Digital Distribution Maps of the Birds populations that occur in the Boreal Forest Region should of the Western Hemisphere (Ridgely et al. [...] Data from the 1990s decade were analyzed to provide an alternative measure of the proportion of breeding birds of each species in combinations of jurisdiction and BCR within the United States, and within Canada south of the arctic.

Intended to provide a recipe for successful development of wildlife habitat models and their implementation in conservation planning, the book could be used in studying wildlife habitat models, conservation planning, and management techniques. Additionally it may be a supplemental text in courses dealing with quantitative assessment of wildlife populations. Additionally, the length of the book would be ideal for graduate student seminar course. Using wildlife habitat models in conservation planning is of considerable interest to wildlife biologists. With ever tightening budgets for wildlife research and planning activities, there is a growing need to use computer methods. Use of simulation models represents the single best alternative. However, it is imperative that these techniques be described in a single source. Moreover, biologists should be made aware of alternative modeling techniques.-
