This booklet titled Derwent River Wildlife Guide, by Veronica Thorp and published in 2000, is a 73 page listing with colour photographs and basic information about all the environments, the flora and the fauna which can be seen at some point along the Derwent River. The booklet is available for loan through the Tasmanian State Library system.
I am sorry that my discovery of this information has come after I have walked so far – it would have been most useful for me to walk with this booklet from day 1 of the entire project. Having said this, there is only one photograph per item and a tiny paragraph of information so that identifying plants and fungi correctly would have been a challenge. While some entries indicate a location where a plant could be expected, most do not have this information. I have a sneaking suspicion that the listings in the booklet may only cover the areas that I have walked which are easiest to access. I suspect that intensive investigation of the Derwent River shoreline and general vicinity between Gretna and Lake St Clair might not have been studied so rigorously.
A Visitor Guide (http://www.parks.tas.gov.au/file.aspx?id=16546) to Tasmania offers a limited selection of animals and environments compared to the comprehensive catalogue available in the Derwent River Wildlife Guide. The Visitor Guide covers all Tasmania which is much broader.
