Although examples are rare, conflicts between species of conservation concern can result from habitat restoration that modifies habitat to benefit a single taxon. A forest restoration program designed to enhance habitat for endangered red-cockaded woodpeckers (Picoides borealis) may be reducing available habitat for the eastern spotted skunk (Spilogale putorius), a forest-adapted sympatric spec...
Despite increasingly more comprehensive policies for forest management, the lastforty years in Mexico has witnessed a continuing pattern of mismanagement. While somehave pointed a finger at underlying factors such as population growth and poverty,focusing on these factors tend to “blame the victim.” Political elements such as acentralized government, a dominant political party, ...
Land cover and forest mapping supports decision makers in the course of making informed decisions for implementation of sustainable conservation and management plans of the forest resources and environmental monitoring. This research examines the value of integrating of ALOS PALSAR and Landsat data for improved forest and land cover mapping in Northern Tanzania. A separate and joint processing ...
Habitat fragmentation increases seed dispersal limitation across the landscape and may also affect subsequent demographic stages such as seedling establishment. Thus, the development of adequate plans for forest restoration requires an understanding of mechanisms by which fragmentation hampers seed delivery to deforested areas and knowledge of how fragmentation affects the relationship between ...
Despite a marked increase in the focus toward biodiversity conservation in fragmented landscapes, studies that confirm species breeding success are scarce and limited. In this paper, we asked whether local (area of forest patches) and landscape (amount of suitable habitat surrounding of focal patches) factors affect the breeding success of raccoon dogs (Nyctereutes procyonoides) in Tokyo, Centr...
BACKGROUND Despite empirical support for an increase in ecosystem productivity with species diversity in synthetic systems, there is ample evidence that this relationship is dependent on environmental characteristics, especially in structurally more complex natural systems. Empirical support for this relationship in forests is urgently needed, as these ecosystems play an important role in carbo...
Several recent EU documents deal with forests and forestry. Some of them also foreseen the launch strategic plans for at national level. The paper presents procedural requirements contents that supposed to be addressed in plans. In a brief analysis drafts forest management regions, we found were prepared accordance existing regulation, which is likely fulfilled future. main headings consistent ...
Participatory forest management, as a model for sustainable forest development, prepares local people to play an effective role in their fate and they enable to participate in the process of sustainable forest development. Present research looks to the gap of between the current status and the ideal status of the forest Bankoul area as a fundamental concern. So, this research has done with the ...
In the Phase IIEcosystem Management Research Program in the Ouachita and Ozark National Forests, an interdisciplinary group of scientists are evaluating the effects and trade-offs ofpartial cutting methods in a replicated stand level study. Information from approximately 2,000 plots is being collected by more than fiftyresearchers during this five-year project with plans to continue data collec...
