The 2008 report card provides information on the catchment indicators that were selected to measure the health of the catchment, as well as the level of repair work being undertaken in the catchment. Through this report card, progress against the targets of the catchment plan can be measured and evaluated. This is the fourth Report Card that has been produced on the catchment.
Catchment Summary: Is the health of the catchment changing?
ALGAL BLOOMS Frequency of non-toxic blooms were lower than the 5-year average
Frequency of toxic blooms were lower than the 5-year average
WATER QUALITY The trend towards decreasing total nitrogen and phosphorus in Seven Mile Creek shown in previous Report Cards has now stabilised to a no change level
All other waterways show no improvement or increasing nutrient levels
REPAIR WORK ON WATERWAYS Level of waterways fencing has been maintained at a steady rate over the last two years. Whilst not all waterways fenced meet the priority category, at 129 kilometres total fenced since 2000, we are only 21 kilometres short of the 2010 target.
PROTECTION OF BUSHLAND The area of bushland protected increased substantially in 2008 to 335 hectares, mainly thanks to three key landholders who have protected substantial blocks of high quality remnant vegetation.
CONTROL OF WEEDS Weed control activity in 2008 was maintained at similar levels to previous years. The Annual Weed Program continues with hopes to extend the program to woody perennials in the future.

How are we doing?     improving     getting worse     no change

Protection of Biodiversity

Control of Weeds
Target for 2015:
Map priority weeds. Achieve a 10% reduction in priority weeds each year

Weed spraying has been maintained at a consistent level with continuing support from the City of Albany, Department of Corrective Services, West Net Rail and the local community. We still require a strategy/program to tackle woody weeds.
