The TLC has developed an Environmental Account for Five Rivers Reserve, using an asset condition accounting method created by the Wentworth Group of Concerned Scientists. This is the first case study to be developed on a private reserve in Australia that could convert ecological monitoring data into a common unit of measurement – called Econd.

The TLC uses Open Standards to produce Management Plans for each of our permanent reserves, and has installed ecological monitoring across our entire reserve estate. Monitoring enables us to track the health and condition of our lands over time and better understand how they respond to major change events including our management work.

In 2015, the TLC adopted the Wentworth Group’s ‘Accounting for Nature’ methodology as a way of recording, presenting and interpreting our monitoring data in a consistent way. In 2016 we determined basal reference condition for our Five Rivers Reserve (total of 11,113 ha) and in 2017 converted our monitoring data for key assets into Econds on a scale of 0 to 100 to show relative change over time.

Environmental accounting allows us to compare the health and condition of all our reserves using a valid reference point for condition. As land managers this enables us to track the effectiveness of our management actions and to identify and prioritise which of our reserves, or which of their conservation assets need more attention, and plan our work accordingly.

We are intending to adopt this methodology for monitoring data collected from other private protected lands in Tasmania as it can be up-scaled to provide regional environmental accounts for consistent and comparable state-wide reporting frameworks in the future.
