Daly River Vegetation mapping project: updated final report

1:100,000 scale map of the native vegetation in the Nothern territory, Project report to NT NRMB, Luke Peel, 2009. Technical Report 08/2009D.

This project was successful in researching and developing a suitable method by which native vegetation can be mapped at a refined scale in a more rapid and cost effective way than previous methods allowed. An intermediate map product of the Daly Catchment was produced at 1:100,000 scale depicting broad structural vegetation community types.

Daly Basin Vegetation Mapping trial methodology completed by CDU eCognition group

Charles Darwin University, Tropical Spatial Sciences Group (2007?)
This trial was to ascertain the capabilities of eCognition to classify remotely sensed data and other products to identify land types and classify them into groups based on vegetation, lithology and location in the landscape.

Daly basin draft vegetation mapping

Report to Dept. of Natural Resources, Environment and the Arts, Northern Territory and Greening Australia, Northern Territory by Bernard Fitzpatrick, Spatial 31 Pty Ltd, 25 Sept. 2006.

Spatial 3i Pty Ltd was engaged to produce a draft map of the vegetation communities of the Daly Catcahment based on LANDSAT TM imagery provided by the Northern territory Dept. of Natural Resources, Environment and the Arts.

Daly River Catchment ? towards an integrated catchment management

Andrew S. Wygralak
ASEG Extended Abstracts Volume 2006 Number 1, ASEG2006 - 18th Geophysical Conference
The Daly River catchment has good soils and is earmarked for the future agricultural development. The NTG placed a Moratorium on major developments, pending completion of an Integrated Regional Land Use Plan. The aim, based on analysis of hydrological, biological, environmental and social studies, is to develop a balanced holistic catchment management approach. Most of the multidisciplinary studies of the catchment completed till now were conducted without sufficient attention paid to the interconnection between economic, environmental, social and cultural aspects of the river catchment management. As a result no integrated catchment management plan has as yet been proposed. Further research is needed to fill the existing knowledge gaps.

Monitoring savannah riparian zone condition in north Australia using image and field based assessment methods

Australasian Remote Sensing and Photogrammetry Conference, 2006
Government agencies responsible for riparian environments are assessing the combined utility of field survey and remote sensing for mapping and monitoring indicators of riparian zone condition. The objective of this work was to compare the Tropical Rapid Appraisal of Riparian Condition (TRARC) method to a satellite image based approach.

Comparison of image and rapid field assessments of riparian zone condition in Australian tropical savannahs

Comparison of the Tropical Rapid Appraisal of Riparian Condition (TRARC) method developed for rapid on-ground assessment of the environmental condition of savannah riparian zones and an image based riparian condition monitoring scheme. Measurements derived from these two approaches were compared and the cost-effectiveness and suitability for multi-temporal analysis of the two approaches were assessed. Results showed that the TRARC method was more cost-effective at spatial scales from 1km to 200km of river in relatively homogeneous riparian zones.

Linking riparian vegetation spatial structure in Australian tropical savannahs to ecosystem health indicators:

semi-variogram analysis of high spatial resolution satellite imagery
K. Johansen and S. Phinn
Canadian Journal of Remote Sensing 32, 3, 1-16, 2006
The objective of this work was to determine if the structural attributes of savannah riparian zones in northern Australia can be detected from commercially available remotely sensed image data. Two QuickBird images and coincident field data covering sections of the Daly River and the South Alligator River- Barramundie Creek in the Northern Territory were used.

Inventory and risk assessment of water dependent ecosystems in the Daly basin, Northern Territory, Australia

G. W. Begg, R. A. van Dam, J. B. Lowry, C. M. Finlayson and D. J. Walden
Supervising Scientist, 2001
The specific aims of this inventory and risk assessment were to map and store in a Geographical Information System (GIS) the area, location and extent of a range of water dependent ecosystems in the Daly basin; establish threats to these ecosystems from forecast and existing water use and land management practices and overlay this information on the GIS-based map; identify which ecosystems are most at risk and where possible provide an assessment of the extent of this risk; and provide a mapping-base describing habitats critical for other key indicator species being investigated in the Daly basin.
