Provest Creek Ecological Restoration

Our client Wild Habitats Inc. received funding through the Federal CEP (Community Environment Program) to restore Provest Creek in Hornsby Heights Sydney back to a healthy creekline.

Provest Creek is fed primarily by stormwater collected in the local urban catchment. At the top of the catchment is Montview Oval which was created from an old landfill site. A quarry operation mining clay shale and fireclay was also in operation from 1960 to 1975.

The restoration will focus on the areas of the creek that are part of Berowra Valley National Park with the permission of NPWS (NSW Parks and Wildlife Service.)

We will be attempting to do the restoration by applying the SERA (Society of Ecological Restoration Australiasia) standards.

The challenge is that we need to incorporate knowledge which is normally difficult to obtain for Bush Regenerators. The grant will allow us to use the services of an ecologist so that we can try and make sure that our regeneration benefits the local fauna.

SERA standards require us to assess the site based on the following attributes with a one to five star rating. This allows us to create a Recovery Wheel and is a good measure of our progress when viewed at the beginning and end of a project.

Dense ground cover of Eragrostis curvula (African Love Grass) and Ageratina adenophora (Crofton) crowding out native grasses.
Zantedeschia aethiopica (Arum Lily) crowding creekline. They are absorbing excess nutrient and possibly providing habitat. Should they be removed?
