Biodiversity: What is it and why is it important

What is it?

Biodiversity (biological diversity) means 'the variety of all life forms'.

Biodiversity refers to the variety of living organisms associated with land and water - the different plants, animals and micro-organisms, the genetic information they contain, and the ecosystems they form.

Why is it important?

Biodiversity underpins the processes that make life possible. An intact biodiversity is critical to the functional integrity of all ecosystems. Healthy ecosystems are necessary for maintaining and regulating atmospheric quality, climate, fresh water, marine productivity, soil formation, cycling of nutrients and waste disposal.

Biodiversity also supports economic activities, with Australian plants and animals attracting tourists and providing food, medicines, energy and building materials. Our biodiversity is a reservoir of resources that remains relatively untapped.

Biodiversity has spiritual and recreational significance for most people and is central to the cultures of Aboriginal people.

Biodiversity is of great value within the Dry Tropics region, although its values and services also extend well beyond the regional boundary to include national and international benefits.
