Although most remaining forest cover in Europe consists of intensively managed plantation woodlands, no studies have examined the influence of management practices on moth communities within plantations.
"In certain areas, people don't even get clean drinking water, and in some areas you can see that most of the forest cover has been destroyed.
However, the non-linear relationship between S. nigritus density and number of patches suggests that even the species that are most tolerant to forest cover changes seem to respond positively only at an intermediate level of habitat fragmentation, being dependent of both a moderate degree of forest cover and a high quality matrix.
The original natural vegetation of Southern Ontario consisted of hardwood forests with great stands of white and red pines on the lighter soils, but, during the 19th century, land clearing and lumbering removed most of the original forest cover.
The most established benefit of forest cover is in controlling erosion and downstream sedimentation.
Although many studies advocate a species-specific response to habitat loss and fragmentation, Sapotaceae as a whole experienced a dramatic decrease in richness in landscapes with reduced forest cover, most likely due to a common response to deleterious effects triggered by the reduction in habitat, and defaunation.
While it has been realised that for ecological security 33% of the land should be under forest cover, in most developing countries it is below 20%.
The results show the KGBRP rehabilitation fence technique delivered tree diversity, plant diversity, tree density and forest cover that most closely resembled old-growth areas.
The results of this sampling approach indicated a decline of forest cover for most US cities at a rate of approximately 7900 ha/year, or 4 million trees per year.
Non-forested ecoregions were assigned SEP values of 0.0 for all tree species under contemporary climate based on the assumption that most area capable of supporting forest cover is currently occupied by trees or mountain shrubs (e.g., in recently disturbed areas) and these generally arid ecoregions have unsuitable climates for trees.
