TORBAY CATCHMENT REPORT CARD 2009
The 2009 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 fifth 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 averagee
Frequency of Toxic blooms was greater than the 5-year average
WATER QUALITY Total Phosphorus though in the 'very high' category for Five Mile Creek is starting to decrease and the low levels of Total Nitrogen in Marbellup Brook are being maintained.
All other waterways have continuing high or very high nutrient levels
REPAIR WORK ON WATERWAYS The level of waterways fencing was significantly down on previous years and not all waterways fenced met the priority category. However, we now have a total of 136km ofwaterways fenced since 2000 and are only 14km short of the 2010 target.
PROTECTION OF BUSHLAND A moderate amount of remnant bush was protected in 2009 (9.4ha)over and above the huge area that was protected in 2008. The target for remnant bush protection and other targets will be reveiwed in 2011 prior to production of the 2010 Report Card.
CONTROL OF WEEDS Watsonia spraying in 2009 was maintained at similar levels to previous years. With funding and the assistance of volunteers and trainee work crews we have started to remove and treat some of the other significant weed species in the catchment such as Sydney Golden Wattle, Taylorina, Typha and Victorian Teatree.

Protection of Biodiversity
Target for 2010:
All priority remnant vegetation patches greater than 1 hectare are fenced and managed to best practice standards
      Hectares of remnant vegetation protected
Following the exceptionally large area of remnant bush protected in 2008, several smaller projects were implemented in 2009, totalling 9.4 hectares.
Control of Weeds
Target for 2015:
Map priority weeds.
Achieve a 10% reduction
in priority weeds
each year

The Watsonia spray program was continued with support from the City of Albany, Department of Corrective Services, West Net Rail and the local community. Future sites for Watsonia eradication need to be prioritised. Removal of woody weed species in road reserve areas around Elleker commenced in 2009.
