Weeds

Weeds

The risk of weed invasion increases after a bushfire as it provides a window of opportunity for competitive weeds to take advantage of extra light, space, nutrients and moisture caused by the absence of desirable plants such as native vegetation, crops or pasture. Weeds can also increase as a result of fire suppression, fire recovery and environmental events.

ACTIONS

1

Monitor for new   weed outbreaks.

2

As imported   hay can carry in weeds, feed stock in small and localised areas so they can   be regularly checked.

3

Take the   opportunity to treat new weed growth that was previously difficult to access   prior to the fire.

FURTHER INFORMATION

In 2009, the Department of Primary Industries (DPI) produced a report called ‘Recovery after fire. Practical steps for landholders’. This document covers many topics and may be useful.

Pest Animals

There is an increased window of opportunity to control pest animals post fire, as their food source has been disrupted.

ACTIONS

1

Fire removes groundcover, so there is an opportunity   to map where rabbit burrows exist. A baiting program is appropriate for large   numbers. A warren ripping and fumigation program should follow.
