The catchment is located within the Southwest Australia Ecoregion, an internationally recognised biodiversity hotspot (Conservation International, 2017). This was the first biodiversity hotspot identified in Australia, with 15 currently registered (Lambers, 2016; Hales, 2014). Learn more about Biodiversity Hotspots here See more about our:
The picturesque Oyster Harbour is highly valued for its role in tourism, commercial and recreational fishing and oyster and mussel farming. Fish traps built near the mouth of the Kalgan River in Oyster Harbour approximately 7000 years ago remain sacred to the Menang people.
The ecosystem collapsed in the 1990s with significant seagrass loss. It has been recovering since, but there is need to boost the active management of waterways and increase actions to improve water quality in the region.
Willyung Creek has a catchment area of about 35 km² which has been almost entirely cleared. The dominant land use is cropping and mixed grazing which covers nearly half of the catchment. The western edge of the suburbs of Albany fall in the southern portion of the catchment along with a large number of lifestyle blocks. In the agricultural areas, waterways mostly retain their natural form whereas they have been converted to drains in the urban areas. Fringing vegetation is missing or poor in most of the catchment. Most of the catchment has soils with a high phosphorus binding capacity, though there are areas of soils near the creek with a low phosphorus-binding capacity. In these areas, any phosphorus applied to the soils can be quickly washed into drains and other waterways. See nutrient report: willyung_creek_2019
Yakamia Creek Living Stream Management Plan. “A Living Stream Management Plan starts with a degraded and fragmented urban waterway and considers ways to introduce ecosystem attributes that are compatible with the multiple constraints that urbanization has created.” by Steve and Geraldine Janicke A reduced quality version has been provided here, divided into three parts.
