This survey describes the vegetation over Nitmiluk National Park in the Northern Territory. The 3 main objectives of the survey were to: 1) To create a vegetation map for Nitmiluk National Park to guide targeted land management. 2) To describe the patterns in vegetation types and significant species in the Park 3) To test and compare methods for generating vegetation maps. The survey analysed more than 1500 vegetation plots between 200 and 2002. Two separate analyses were undertaken, one concentrating on describing the patterns in the floristic data and the other using GIS data to derive a vegetation map. The resulting landcover map describes 13 vegetation classes; distinguishing the substrate (soil and rock) and structure of vegetation and provides mapping at three different scales, 1:50 000, 1:100 000 and 1:250 000. Nitmiluk National Park covers an area of 1,000 km2 of mostly rocky country enclosing the upper reaches of the Katherine River. The main park entrance is located approximately 30km from the townsite of Katherine.
