bushland is located in small, narrow, fragmented reserves in gullies and along
the foreshore. The reserves are criss-crossed by drainage lines and walking
tracks. There are residential or industrial properties within 100 m of any part
of these reserves. Urban pressures on this bushland are immense.
Some of the threats to bushland Lane Cove
- Clearing of bushland for residential, industrial and road
- Adverse human impacts e.g.
- rubbish dumping
- impact of pets and feral animals on native wildlife
- weed and exotic plant dumping and escape
- residential property encroachments
- illegal emptying of swimming pools and other pollutant
- Structural changes to bushland e.g.
- weed invasion
- removal of habitat such as bush rock, logs and dead
- changes to fire regime
- increased soil nutrient levels
- decreasing species diversity including tree
- Changes to drainage e.g.
- stormwater from catchments surrounding bushland reserves is piped
to outlets on the edge of bushland, generally in areas that were once dry
slopes, and interrupted normal flows to other areas.
- Destabilisation of water courses e.g.
- nutrient pollution
- changes to ground water
- increased sediment loads
The long term survival of bushland in
this urban environment requires an integrated approach incorporating planning,
on ground works and an active community involvement.
