Project Description
The terrestrial ecosystem baseline studies for the Beetaloo Sub-basin SREBA produced a fine scale vegetation map for the study area, described the biogeographic patterns of flora and fauna in representative vegetation communities and habitat types and surveyed for target significant and sensitive fauna. These studies identified species and habitats of high conservation value, and developed recommendations for future monitoring. These studies were undertaken by the Northern Territory Government Department of Environment Department of Environment, Parks and Water Security, Flora and Fauna Division.

Abstract
The distribution of broad vegetation groups was mapped across the Study Area at a scale of approximately 1:100 000 using an Object Based Image Analysis (OBIA) approach. Field survey data were used to train a random forest model, along with a set of image data layers that are likely to discriminate between the classes and predict their distribution across the Study Area.
Detailed methods and results for the vegetation mapping are provided in the Terrestrial Ecosystems Baseline Report. Technical descriptions of broad vegetation groups and communities are provided in the attachment file (5 SREBA Terrestrial Ecosystems Chapter 3 Flora Appendices E.pdf).
