Best practice for on-ground property weed detection

Weedy species will continue to enter Australia while existing species expand their range via various pathways of weed spread (the subject of Defeating the Weed Menace Project UNE61, Pathway Risk Analysis for Weed Spread within Australia).

Improving Management of Salvinia in Temperate Aquatic Ecosystems

Freshwater ecosystems in temperate regions in Australia remain under continued invasion by the prolific aquatic fern, Salvinia molesta because control methods have been inconsistent and ineffective. In a case study system, the Hawkesbury-Nepean River, we

Understanding and determining mechanisms to prevent invasion in coastal vegetation

We investigated the effect of richness of different growth forms (functional richness), the arrival order (priority effects) and competitive interactions in mediating plant community resilience to invasion events. We constructed mesocosms composed of dune…

Quantification of the environmental costs of weeds

The purpose of this project was to quantify (a) the environmental impacts and (b) the relative benefits and costs of control of two tropical invasive grasses. The project reviewed the existing studies on the environmental impact of tropical invasive grass…

Importation, rearing and field release of the Cape broom psyllid, Arytinnis hakani

This project, led by the South Australian Research & Development Institute (SARDI), in collaboration with CSIRO Entomology and other partner organisations, sought to complete host-testing on lupin species at the CSIRO laboratories in Montpellier, France….

EWeedMAT:Environmental Weed Management Action Tool

The Yorke Peninsula Case Study

The Environmental Weed Management Action Tool (EWeedMAT) was initially developed in the South East Natural Resources Management (SENRM) region of South Australia.1 Native vegetation in the South East has been reduced to 11% of its original area and is now…

Developing a Model for Environmental Weed Management in Fragmented Landscapes

A case study

The Environmental Weed Management Action Tool, EWeedMAT, was initially developed in the South East Natural Resources Management (SENRM) Region of South Australia (Herpich, 2006). Like much of temperate Australia, remnant native vegetation in this region…

Detection of Pinus radiata wildlings in remnant vegetation in the lower SE of South Australia, and far SW of Victoria

a Pilot Study

This investigation attempted to use fine spatial scale Quickbird imagery and digitised aerial photography to indicate the location of pine wildlings within a selection of vegetation communities.

Control of Pine wildlings in remnant vegetation: Aspects of management in the Green Triangle Region

Radiata pines (Pinus radiata) were introduced into South Australia and Victorian in latter part of the 1800s. The second half of the 1900s saw large-scale plantation development. Breeding for faster growth and greater volume also occurred in this period.

Detecting Pinus radiata in Bushland Technical Report

The primary aim of the projec t is to develop an automated remote sensing system to identify large pine wildlings in remnant vegetation, using satellite imagery. As such it is a preliminary study of a new application of automated remote sensing.
