Boyagerring Brook Catchment
Boyagerring Brook rises in the east of the Toodyay Shire. It flows south-west through mainly cleared farmland, past the Toodyay District High School, and into the Avon River opposite the Toodyay town site. The Brook ceases to flow in summer but does retain a number of pools fed by springs, a valuable refuge for wildlife.Much of the area is dominated by yorkgum jam soils, so named from the vegetation found growing there. Only a few scattered remants remain as most areas have been extensively cleared for farming. Wandoo (Eucalyptus wandoo) grows with yorkgum on the hilly areas where quartzite rocks are found. Flooded gum (Eucalyptus rudis), Swamp Sheoak (Casuarina obesa) and the Needle Tree (Hakea preissi) dominate the winter wet depressions and water courses.
Boyagerring Brook Catchment Group was formed to initiate projects to protect areas of existing vegetation and fence off and revegetate other areas along the Brook.
In February 2007, a large bush fire raced across the catchment on a day of temperatures around the 50 degree celcius mark, fanned by extremely strong winds. The resultant damage in the catchment has been catastrophic, with rising water tables and salinity replacing stands of remnant vegetation.
Issues in the catchment are being evaluated, but will need long-term planning.
