Remnant Patch Size

Remnant Patch Size

The fragmentation of native bushland reduces the availability of habitat and resources, the ability of organisms to move, colonise and reproduce and makes communities susceptible to disturbances such as fire, drought, grazing, feral animals, weeds, clearing and climate change. Many organisms are considered threatened in our region as they only occur in, or rely on, small fragments of remnant vegetation. The number of threatened species in our region can be influenced by managing for these threats by; creating vegetation corridors and buffers, fencing bushland fragments and waterways to reduce grazing pressure, reducing weed and feral populations, implementing sustainable fire regimes and designing replanting areas to be resilient in a drying climate

How can we monitor progress?

At Wheatbelt NRM Inc. we have searched for data that can help us monitor the status of bushland fragmentation at several levels. At the top level we can directly measure the number and size of remnant patches and revegetation efforts. At a deeper level we can monitor the number of species considered threatened across the region and the density of feral animals and examine patterns in fire occurrence.
