Vegetation Trend and Connectivity Analysis

2rog conducted spatial analyses to identify 5-year trends in vegetation cover, vegetation connectivity, and private land conservation at NSW and Local Land Services regional scales. We also developed a state-wide refugia layer that mapped out climate and wildfire refuges, and a state-wide revegetation layer that prioritised places in the landscape in which revegetation could be…

UAV landform stability and sediment monitoring

The former Ranger Mine, in the Northern Territory has closed and is currently delivering rehabilitation activities on the Ranger Project Area. Part of the task involves re-creating a landscape that can be integrated back into the local environment. However, reconstructing landscapes can be tricky and when you add in the extreme wet and dry environments of the Top End, keeping the sediment and soil in place requires a lot of experience.

2rog were engaged to develop and implement an approach to monitor sediment movement across recreated landscapes. We worked with ERA to assess the suitability of Un-manned Aerial Vehicle (UAV) imagery to keep an eye on the landform month to month and guide any field assessments or management required.

Our spatial team used specialised software to process​ the UAV imagery to create high definition ortho-mosaic images for each capture time. Our image analysis and hydrology experts then analysed the images in sequence to detect change and highlight any potentially problematic locations.

We reported our findings back to the on-site team who could then target the areas of concern, making landform and structure adjustments to minimise or prevent ongoing erosion. The combination of technology and methods we developed proved to be a valuable monitoring tool for this rehabilitation project.

Areas of concern could be monitored across the entire target site and management actions directed in a timely manner.

Granite Belt Irrigation: Project Conditions Variation and Offset Strategy

Granite Belt Water Limited commissioned 2rog to help them vary the conditions of Commonwealth approval for the Granite Belt Irrigation Project. Variation to the approval was necessary to accurately quantify and reflect the ecological values present within the project area and ensure that compensatory measures were commensurate with the impacts of the project. Discussions with…
