Download or read book Predicting Canopy Closure for Habitat Modeling written by Great Lakes Forestry Centre and published by Sault Ste. Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1995 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a project to develop quantitative models that could be used to estimate crown cover density of forest stands from available data in the Ontario Ministry of Natural Resources Forest Resource Inventory information system. The investigators developed and tested models in two areas: the Algonquin Provincial Park and the Shining Tree Crown Management Unit in the Gogama District. The testing included the potential role of the Forest Resource Inventory working group and stand variables such as stocking, height, volume, site class, and age. The possible influences of geographic location and the photo interpreter who carried out the original Forest Resource Inventory classification were also analysed. The factors which provided the strongest estimates of crown cover density or which added to the predictive power of the model equations are noted.

This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.
Download or read book Ungulate Management in Europe written by Rory Putman and published by Cambridge University Press. This book was released on 2011-04-28 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers a number of problems posed by ungulates and their management in Europe. Through a synthesis of the underlying biology and a comparison of the management techniques adopted in different countries, the book explores which management approaches seem effective - and in which circumstances. Experts in a number of different areas of applied wildlife biology review various management problems and alternative solutions, including the impact of large ungulates on agriculture, forestry and conservation habitats, the impact of disease and predation on ungulate populations and the involvement of ungulates in road traffic accidents and possible measures for mitigation. This book is directed at practising wildlife managers, those involved in research to improve methods of wildlife management, and policy-makers in local, regional and national administrations.
