Although the ecosystem is heavily fragmented at present, it still carries a great diversity of plant and animal species, many of which are endemic. A range of techniques, including planting longleaf pine seedlings, introducing prescribed burning regimens, managing native ground cover, and controlling invasive species within the ecosystem, are ...
The diversity of animal genetic resources includes diversity at species, breed and within-breed level. Known are currently 8,800 different breeds of birds and mammals within 38 species used for food and agriculture. [8] The main animal species used for food and agriculture production are cattle, sheep, goats, chickens and pigs. In the livestock ...
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
Invasive species seem to increase local (alpha diversity) diversity, which decreases turnover of diversity (beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, [ 187 ] but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North ...
Afforestation protects the biodiversity of plants and animals which allows the sustenance of ecosystems that provide clean air, soil fertilization, etc. [61] Forests support biodiversity conservation, providing habitats for about 80% of the world's biodiversity and contributing to ecosystem restoration and resilience.

For larger animals, these may include spotlight counts, track counts and roadkill counts, as well as presence at monitoring stations. [2] In many plant communities the abundances of plant species are measured by plant cover , i.e. the relative area covered by different plant species in a small plot. [ 3 ]
Biodiversity is the measure of biotic and abiotic diversity in an ecosystem, described by heterogeneity. [1] The loss of biodiversity in agriculture has been an increasing issue since the global increase of food demands and success of popular crops. [3] [4] This loss of heterogeneity declines species biodiversity on agricultural lands. [5]
Polyculture increases local biodiversity. Increasing crop diversity can increase pollination in nearby environments, as diverse plants attract a broader array of pollinators. [6] This is an example of reconciliation ecology, accommodating biodiversity within human landscapes, and may form part of a biological pest control program. [15]
