Biodiversity
- Biodiversity is the variety of organisms in an area. It can be considered on a local or global scale.
- Species richness is a measure of the number of different species in a community.
- An index of diversity measure biodiversity taking into account species richness and the number of individuals in each species
- Index of diversity =
N = total number of organisms of all species
n = total number of organisms of each species
n = total number of organisms of each species
- Farming techniques reduce biodiversity. E.g. monoculture, use of herbicide & pesticides, hedgerow removal and woodland clearance
- Conservationists protect biodiversity with methods such as: giving endangered species legal protection, creating protected area & The Environmental Stewardship Scheme.
- A balance between conservation and agriculture is needed
