Why Conserve Plants and Invertebrates?
- maintain biodiversity and wildlife corridors
- food source
- Biological Resource
Wildlife Corridors:- a route or pathway allowing movement of insects to sites fo refuge or habitats
Biological Resources:- A living organism that is renewable and of use to humans
- food source
- help to pollinate plants
- Preservation of organisms/environments that are at risj from human actvityy, over farming, pollution, building, introduction of new psecies. Protecting areas of land, currently unaffected by humans in their unused form
- Requires management to poissbly reclaim an ecosystem or create a new habitat
- resolves conflict between local inhabitants, tourists and legislations - National Parks, SSSIs, CITES and EIA.
SSSI - sites of special scientific interest
CITES - Convention on International Trade in Endangered Speciies of wild fauna and flora
EIA - Environmental Impact Assessment
...products are harvested at levels which leave suffficient orgnaisms to grow and repriduce - it can be carried out indefinitely and similar quantities of products are harvested every year...
- Native trees planted - sustainable in the environment
- saplings are spced to reduce competition
- Young trees are supported and protected to prevent damage from grazers
- Confiers (planted for fast growth) and decidious broadleved species are planted to create/protect different habittats and increase aesthetic effects
Deciduous plants lose leaves to reduce water loss and reduce wind damage
Pollarding and Coppicing
Pollarding:- cutting higher up trees to avoid deer and grazers eating the stems - they produce wildlife corridors
Coppicing:- cutting trees close to the ground so new growth forms - produces small diameter stems for fencing, firewood, furniture
Different area are coppiced or pollarded each year to allow regrowth and provide different habitats, increasing biodiversity.
