The Tiger (Panthera tigris) population in India has undergone a sharp decline during the last few years. Of the number of factors attributed to this decline, habitat fragmentation has been the most worrisome. Wildlife corridors have long been a subject of discussion amongst wildlife biologists and conservationists with contrasting schools of thought arguing their merits and demerits. However, i...
Animals can require different habitat types throughout their annual cycles. When considering habitat prioritization, we need to explicitly consider habitat requirements throughout the annual cycle, particularly for species of conservation concern. Understanding annual habitat requirements begins with quantifying how far individuals move across landscapes between key life stages to access requir...
Critical habitat is defined under Section 2 of Canada’s Species at Risk Act (SARA) as, “the habitat necessary for the survival or recovery of a listed wildlife species and that is identified as the species’ critical habitat in the recovery strategy or in an action plan for the species”. SARA requires the development of recovery strategies for species listed as Endangered, Threatened or Extirpat...

Farmers who participate in the Conservation Reserve Program (a voluntary program that removes highly erodible cropland from proauction) may be able to supplement their annual government payment by renting out their land to hunters, fishers, birdwatchers, or wildlife photographers. Those recreational activities may boost income and employment in the larger region by raising retail spending in ne...
Abstmrr: Past str~dies on the nesting habitat of northern goshawks (Accipiter gentilis) often relied on nests fomid opportunistically, either during timber-sale operations, by searching apparently "good goshawk habitat, or 1)y other search methods where areas were preselected based on known forest conditions. Therefore, a bias in the characterimtion of habitat surrounding northern goshawk nest ...

this time each year, we're asked if there are any advantages to placing Christmas trees or other types of brush piles in lakes for habitat enhancement. To answer that question, we've provided excerpts from an article written by Dr. Mike Allen, Associate Professor here at UF's Dept. of Fisheries and Aquatic Sciences. 1 Dr. Allen specializes in fisheries ecology and has produced numerous studies ...
In the eastern U.S. Coastal Plain and Piedmont region, diverse inland wetlands (riverine, depressional, wet flats) have been impacted by or converted to agriculture. Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these con...
