Targeting threats alone “won’t save our wildlife” … so what would?

I was fortunate to be a co-author on the paper recently published in Frontiers in Ecology and the Environment led by Viv and Ayesha Tulloch, “Why do we map threats? Linking threat mapping with actions to make better conservation decisions.” (see media release PDF).

This is a great thinking piece about why we should probably not use threat maps “as is” to inform conservation decisions and how threat maps should be included as part of the decision process. I would recommend reading this paper if you are new to structured decision making and would like an easy read. The authors have done a fantastic job at explaining the risk of not following a transparent decision making process.

As a side note, our priority threat management work in the Pilbara was highlighted as a good example of making transparent decisions (No doubts they are other good examples in the literature!). It’s always a privilege to be acknowledged by our peers, it’s even better when these are esteemed close collaborators. Thanks for your support!

Free toolbox to solve stochastic dynamic programming problems in R, MATLAB, OCTAVE and SciLab

If you are interested in finding the best decisions over time to save or eradicate the cutest species, then you are probably interested in using Stochastic Dynamic Programming (SDP) or its mathematical model Markov Decision Process (MDP). If you have a burning problem ready to be solved but not sure how to, then good news we have released the MDPToolbox (ver. 4) in R, Matlab, Octave and Scilab. Please spread the word, the toolbox is free! Thanks to Ecography, you can now support our efforts by citing our paper:

Pilbara shows how to save the most species per dollar: report now available!

We are pleased to announce the release of our report on ‘Prioritising threat management for Pilbara species of conservation significance’ (PDF, 10Mo)(The Conversation). This was a very rewarding collaborative project with scientists from CSIRO, QUT, UQ, and WA Dept Parks and Wildlife, with input from 49 experts across land management, policy, industrial, agricultural, indigenous and academic sectors, and was funded by Atlas Iron through the Dept of Environment Pilbara Taskforce.

The work comes at an important time in the Pilbara’s history and we hopeful that it will have a positive impact.

Weeds in the Lake Eyre Basin? Listen to Jennifer Firn on Radio National

Jennifer Firn was on Radio National speaking (Bush Telegraph) about our priority threat management work targeting weeds in the Lake Eyre Basin. You can check our previous blog post on the subject and the report (PDF). Well done Jennifer!
