Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels.
A fir tree snag among living fir trees. In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches.In freshwater ecology it refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris.
Habitat destruction through natural processes such as volcanism, fire, and climate change is well documented in the fossil record. [2] One study shows that habitat fragmentation of tropical rainforests in Euramerica 300 million years ago led to a great loss of amphibian diversity, but simultaneously the drier climate spurred on a burst of ...
The resilience of human food systems and their capacity to adapt to future change is linked to biodiversity – including dryland-adapted shrub and tree species that help combat desertification, forest-dwelling insects, bats and bird species that pollinate crops, trees with extensive root systems in mountain ecosystems that prevent soil erosion ...
Climate change showed an impact on the mortality of some dominant tree species, as observed in the Korean pine. [45] Climate change also showed an effect on the composition of species when forests were surveyed over a 10- and 20-year period, which may disrupt the overall productivity of the forest.
Coarse woody debris (CWD) or coarse woody habitat (CWH) refers to fallen dead trees and the remains of large branches on the ground in forests [1] and in rivers or wetlands. [2] A dead standing tree – known as a snag – provides many of the same functions as coarse woody debris. The minimum size required for woody debris to be defined as ...
Wildlife management is the management process influencing interactions among and between wildlife, its habitats and people to achieve predefined impacts. [ 1 ] [ 2 ] [ 3 ] Wildlife management can include wildlife conservation , population control , gamekeeping , wildlife contraceptive and pest control .
Climate change has a direct impact on the productivity of the boreal forest, as well as health and regeneration. [15] As a result of the rapidly changing climate, trees show declines in growth at the southern limit of their range, [ 62 ] and are migrating to higher latitudes and altitudes (northward) to remain their climatic habitat, but some ...
