Biological survey-based programs

Biological surveys are a key method for collecting information. DEWNR collects detailed information on the size, distribution, abundance, growth, birth rates and mortality for species of plants and animals - threatened or common, pests or endemic - in marine and terrestrial environments.

Terrestrial

Since 1971, DEWNR has been systematically surveying and mapping the distribution of vascular plants and vertebrate fauna of the state in the Biological Survey of South Australia.

Marine

Understanding coast and marine habitats is essential for managing the marine environment. Marine habitat mapping and biological surveys for baseline information have been performed in locations throughout South Australia in collaboration with other various organisations. This significant undertaking can be viewed as a series of 19 baseline reports.

Wetlands

DEWNR has been working on regional scale wetland inventories for a number of years.

Coastal, dune and clifftop

The Coastal Dune and Clifftop Vegetation Survey of SA describes and measures the structure and composition of coastal dune and clifftop plant communities and their relationship to regional and environmental factors. Conducted 1996-1999, this survey added over 22,000 plant records to DEWNR's Biological Databases of SA and nearly 7,000 specimens to the State Herbarium of SA, over 200 of which have conservation significance. This valuable resource is used to help ensure ecologically sustainable development along the coast as well as guide revegetation programs on which local plant species should be used for restoring and stabilising damaged dune systems.

Threatened and abundant species

Research and survey efforts are critical for the management of species and populations. Programs are designed specifically to gain a more detailed understanding of species and populations of concern. These data are used to develop plans to recover threatened species or to ensure abundant species are managed sustainably.
