Rat eradication on South Georgia – what a fantastic effort by an NGO on a shoestring budget

Do Environmental Offsets deliver for Carnaby’s Cockatoo?

February 7th, 2018

Brooke Richards (2016) submitted an honours thesis titled ‘Do Environmental Offsets Deliver for Carnaby’s Cockatoo?’ and we thought the findings of this thesis may be of interest to a wider audience. Environmental offsets are applied when there is a significant residual environmental impact for a proposed development (Government of Western Australia 2011). The Western Australian […]

Retreating glaciers in the Antarctic and implications for penguins

January 24th, 2018

This time last year Graham and I were lucky enough to have spent about three weeks visiting the Falkland Islands, South Georgia and the Antarctic Peninsula.

Terrestrial Ecosystems gets a wildlife conservation detection dog

October 26th, 2016

Wildlife or conservation detection dogs are now widely used in Australia and overseas to locate native and feral animals, their scats and retreats. They are also used to find particular plants and for locating drugs and explosives (Wasser et al. 2004, Smith et al. 2005, Arnett 2006, Long et al. 2007, Cablk et al. 2008, […]

Assessing disturbance impacts using a bio-indicator

August 10th, 2016

After receiving multiple queries about the Rehabilitation and Degradation Index (RDI) discussed briefly in last weeks post I thought I would provide a bit more information. More frequently, state and commonwealth government environment ministers have required development proponents (i.e. land developers, mining companies etc) to monitor on-going potential impacts on the biodiversity in areas adjacent […]

However, data are only comparable when the same protocol has been used. Baseline data Most fauna impact evaluations compare aspects of the fauna assemblage or the abundance […]
