This dataset combines "key ecological values" within intact forest landscapes in order to identify what can be called "key ecological areas" that is, the most valuable areas from an ecological perspective. Although intact forest landscapes have intrinsic value in themselves, identifying "key ecological values" within intact forest landscapes is challenging due to the limited amount of information on most remaining intact areas. It is also difficult to evaluate trade-offs in various prioritization schemes, as value judgments are required and values vary widely. In addition, the methodologies that have been developed for identifying and prioritizing values may not yet be sufficiently refined in order to receive...
Treed and treeless Intact Forest Landscape Fragments and Fragmented Forest Land within Alberta's forest ecozones.
This map is the first global assessment of intact forest landscapes based on the latest available satellite imagery (2000-2004). It shows the remaining blocks of forest landscapes larger than 500 sq km unfragmented by roads, settlements, waterways, pipelines, power lines etc. These forest landscapes are natural ecosystems from the forest vegetation zone which are mostly forested but also contain swamps and other non-forested ecosystems and which are without significant visible signs of human impact such as logging, burning or other forms of clearings. This map was based mostly on the base of 2000-2002 Landsat images, some areas was updated on the base of 2003-2004 Landsat, IRS and Aster images. This map is prepared...
The sustainable management of Canada's forests is an important policy priority for Canadians and this priority is acknowledged by Canadian governments and by many forest companies that operate in Canada. The anthropogenic (human) modification of forest landscapes - via road building, logging, oil and gas development, etc. - is an issue of significance for sustainable forest management. Knowing the number, locations, areas and concentrations of the remaining naturally-occurring forest landscape fragments can improve forest management and forest conservation decisions at multiple scales. By our definition, a forest landscape fragment is a remnant of an intact forest landscape. It is a contiguous mosaic of naturally...
This dataset displays the boundaries of Intact Forest Landscapes for the Tongass region of the state of Alaska. Intact Forest Landscapes are defined as areas at least 50,000 hectares that are absent of human disturbance visible on satellite imagery (e.g., roads, logging, mining, settlement). For more information, see the full report, available on the Global Forest Watch website (www.globalforestwatch.org), or the Conservation Biology Institute website (http://www.consbio.org/cbi/projects/show.php?page=alaska).
