Weed Management

Common to many urban environments, the presence of weeds can present a threat to biodiversity within our bushland reserves, parks and gardens.

A weed is defined as “a plant out of place”.

Weeds are very context specific. In bushland we consider any plant which is not historically part of a given ecosystem a weed, thus even a non-local native plant may be a weed outside of its natural range. To provide clarity we use the term “indigenous plant” to refer to those plants which are naturally a part of the ecosystems which occur in our area.

Removing weeds forms a large part of what we do to manage and protect bushland. Work priorities are based on the level of threat a given weed may present to the overall functioning of an ecosystem.

Some weeds are considered such a widespread threat that their control or removal is required by law.
