The removal, loss or disturbance of individual organisms of a specific species results in loss of biodiversity. Biodiversity is the variety of life forms: the different plants, animals and microorganisms, the genes they contain and the ecosystems they form. Maintaining biological diversity is about the sustainable use of biological resources and safeguarding the life-support systems on earth.

Water Bug Survey. This page has results of water bug surveys used to calculate a Stream Pollution Index for a waterway.
EHMP - Coral Monitoring measures the change in biological structure of coral reefs in Moreton Bay over time. Results for 2001 and 2002 coral monitoring are available from this site.
Fish kills . This page has information on fish kill incidents reported to the EPA since March 2002.
Seagrass depth range and distribution. The EHMP website has information on seagrass depth range and distribution in Moreton Bay, southern Queensland.
StrandNet - Marine Wildlife Strandings. The EPA maintains a database of marine wildlife strandings and deaths, called StrandNet. This records information on where injured, dying and dead marine cetaceans (whales and dolphins), pinnipeds (seals and sea lions), dugong and turtles have been found in Queensland.
