Description / Abstract: Summary: The Northern Territory occupies approximately 18% of Australia and covers a large range of environments and climatic regimes. Native vegetation defines the character of most of this landscape. The only presently available NT wide standardised vegetation mapping is derived from the 1:1 million scale vegetation map completed in 1990. This earlier mapping has been updated with more recent mapping of most of the closed forest types in the NT (NVIS ver 3 present and Pre-european dataset). The vast majority of NT vegetation communities still remain mapped at a broad scale (1:1K). The current NT wide mapping, while useful for providing an overall ecological perspective of the NT, is inappropriate for regional or catchment level planning issues presently emerging with the increased development and modification of the NT environment. A workshop was held in March 2007 to scope the need for more detailed vegetation mapping than currently available It was attended by a number of agencies and non-government organisations including Qld Herbarium, DPIFM, the Australian Defence Department, Greening Australia NT, Charles Darwin University, private consultants, as well as various branches of NRETA itself. Participants all agreed that finer scale mapping is needed and that the rationale for such a system needs to be clearly presented to potential funding bodies. In addition participants thought that any finer scale mapping system/program that is developed should aim to: Have the capacity to be updated with new information. Maintain IBRA bioregion uniformity by mapping whole bioregions at a time. Keep relationships between land and vegetation mapping units close (ecosystem rather than pure vegetation mapping). Be an adaptive system that enables even finer scale mapping to be conducted in the future. Provide for engagement of Indigenous Land holders. A scale of 1:100,000 was deemed the most appropriate and practicable scale at the workshop. On consideration of patterning within the vegetation types in the NT and current NRM needs, the simplest and quickest approach for future mapping would be: Task 1 1:100,000 mapping of the broader patterned vegetation in the Top End. Retain current 100k mapping of MVF, melaleuca, mangrove etc Task 2 Separate mapping of important, discrete vegetation types such as wetlands, paleo drainage channels, and riparian vegetation in the Arid region (100k-50k ?). Task 3 Separate mapping of seasonally inundated floodplains of Top End coastal (100k-50k scale). Indicative costings to complete Task 1 are in the order of $3-5 million. The report is divided into five sections Section 1 Background material. Section 2 Possible Approaches with indicative costings. Section 3 Funding sources. Section 4 Current Initiatives and projects which complement a mapping program. Section 5 Protocols, mapping standards, procedures etc. (to be developed prior to any mapping).
