In 2005, Brown brought a legal case against Forestry Tasmania in the Federal Court, in an attempt to protect Tasmania's Wielangta forest from clearfell logging. The 1997 Tasmanian Regional Forest Agreement (RFA) exempted logging operations from endangered species laws but required the protection of endangered species. Bob Brown brought a case against Forestry Tasmania citing threats to endangered species like the Swift parrot and Wielangta Stag Beetle. In December 2006, Judge Shane Marshall awarded the case in Brown's favour. On appeal to the full bench of the Federal Court level, the case was lost, without rejecting the earlier judgement that logging would further endanger these species. In May 2008 the High Court denied leave to appeal that decision after the wording of the RFA was changed.
