Southwestern Australia is an area of great biological interest which has been subjected to extensive changes as a result of development for agriculture. Widespread clearing of native vegetation has seen the loss of over 90% of the original cover vegetation, most being removed in the last 60 years. This book looks at the effect of these changes on the distribution and abundance of every species of bird recorded in the wheatbelt since the area was colonized by Europeans in the 1800s, comparing current satus and distribution with that recored earlier in the century. Maps are provided for each species, showing the comparative distribution, with seasonal/annual variations also considered. The final section of the work analyses practical solutions to conserving the dwindling species in the belt.
