methods of maintaining biodviersity

What is insitu

Within natural habitats

What is exsitu

Not within natural habitats

What are the benefits of INSITU to o with diveristy

The genetic diveristy is maintained - individuals arent bred captive lay

What are the benefits of INSITU to do with interdependence

All organism interdependant so preventing extinction of one species helps preserve other species

What are the INSITU methods of maintains biodiversity

Marine conservation zones + wildlife reserves

The marine - areas for wildlife to recover and repopulate (e.g areas where fishing + tourism’s arent all over)

Wildlife reserves - same concept but on land

• e.g controlled grazing and restricting human access

What is the main idea of EXSITU

Removing organisms from natural habitat to try and protect them

What are the methods of exsitu with botanical gardens and seed banks

Botanical gardens

• a wide range of plants species can be grown in botanical gardens providing with optimal conditions for growth

Seed banks

• store of genetic material - seeds are stored in water + temperature controlled environments to keep viable for longer

• They’re stored as a backup for endangered plant species

What is the method of captive breeding?

Programmes - reproducing animals in zoos and aquariums

The aim is to increase the number of endangered species

Individuals reintroduced to wild

Provide animals with shelter and supply of food

In terms of captive breeding what organisms born in captivity may not be able to be suitable for release

Diseased

Bad Behaviour

Genetic races ( no interbreeding)
