As in all regions, prevention is the most desirable and
cost-effective approach to weed control. It is especially critical
in areas that are still relatively weed-free. Unfortunately, there
are currently no restrictions on importing plants into north-east
Arnhem land.
Prevention issues
There is a strong case to develop an approved list of plant
species, and for residents to be restricted to planting these or
local native species. Movement of weed seeds also occurs through
importation of hay to use as garden mulch. In addition, the
numerous low-level creek crossings in the region provide great
potential for weed propagules to be washed off vehicles and infest
currently clean catchments. All these issues need to be
addressed.
Education and awareness
Education and awareness are also vital. The Caring for Country
Unit of the Northern Land Council and Greening Australia's
Aboriginal Landcare Education Program are running culturally
appropriate programs to help Aboriginal people deal with weed
problems. These and similar programs need to be extended, with
particular emphasis on developing suitable educational materials
and training.
