CLEARING

Loss of trees for new and infill development. Removal of dead trees also has the potential to reduce habitat for local fauna by removing nesting sites for birds and possums.

MOWING

Creeping loss of bushland through expanded mowing.

FRAGMENTATION

Isolating native plants communities and making them vulnerable to weeds.

ALTERED DRAINAGE

Runoff from roads and drains adds nutrients and moisture to bushland.

INTRODUCED SPECIES

Weeds thrive in disturbed environments and can damage native vegetation.

ALTERED FIRE REGIME

Changes in the patterns of bushfires can lead to loss of biodiversity and local extinction.

CLIMATE CHANGE

The greenhouse effect is changing climate which may affect plant distribution.

FERAL ANIMALS

Can remove important small native animals from isolated bushland reserves. These animals are important for pollinating native plants and spreading seed, as well as for other reasons.
