Impacts of agriculture | - Agricultural ecosystems controlled by humans
- Farmers select species, reducing genetic variety of alleles
- To be economic, no. of individuals in species needs to be large
- And any particular area can only support a certain amount of biomass |
Factors that reduce biodiversity | - Woodland clearance, trees, animals die, migrate
- Hedgerow removal
- Pesticides, kill organisms
- Herbicides, reduces plant biodiversity, killing them
- Monoculture, farmers growing 1 type if crop |
Conservation techniques | - Maintaining hedgerows
- Maintaining existing ponds, create new ones
- Reduce use of pesticides
