How are things going in the Torbay catchment? Since the development of the " Watershed Torbay project ", a lot of work has been done, but what is the impact of that work?

The following catchment indicators were chosen by the community as providing a meaningful measurement of catchment health and whether we are meeting the targets set in the catchment restoration plan.

improving getting worse no change

Catchment Summary: Is the health of the catchment changing?
ALGAL BLOOMS Frequency of non-toxic blooms were above the 5-year average
Frequency of Toxic blooms were lower than the 5-year average
WATER QUALITY Seven Mile Creek is the only waterway with a clear decreasing trend with both N & P.
Other creeks show no improvement or increasing nutrient levels
REPAIR WORK ON WATERWAYS Level of fencing of waterways in the catchment has been maintained at a steady rate
CONTROL OF WEEDS Level of weed control activity in the catchment has been maintained at a steady rate
PROTECTION OF BUSHLAND 36 ha of bushland protected

How are we doing?   improving    getting worse    no change

Repair Work on Waterways
Target for 2010:
Fence and revegetate
150kms of priority
      Km's of waterways fenced2000 - 200420052006
68.5 km17.5 km17.5 km
All waterways foreshore condition mapped and prioritised for fencing
Protection of Biodiversity
Target for 2010:
All priority remnant
vegetation patches greater
than 1 ha are fenced and
managed to best practice
      2006: 36.5 ha of remnant vegetation protected
All remnant vegetation has been mapped and prioritised for protection through
a model which analyses the remnant by: size, connectivity to other vegetation,
and representation of vegetation type in conservation areas.
Control of Weeds
Target for 2015:
Map priority weeds.
Achieve a 10% reduction
in priority weeds
each year
Km's of road verge sprayed2002200320042005
Weed spraying is at a consistent level. Great partnerships developed between
the City of Albany, Department of Corrective Services, West Net Rail and the
community to achieve this. Mapping and monitoring still needed.
