FIRE RECOVERY IN THE GROSE VALLEY

A post-fire assessment, vegetation mapping and ecological monitoring framework

ABOUT THE PROJECT

This project will engage scientists and community members in conducting critical post-fire fieldwork that will inform remedial actions and preparations for future fire events.

The field area is the iconic Blue Gum Forest and Grose Valley within the Blue Mountains, where 70 percent of the World Heritage Area was severely impacted by the 2019-20 fires.

Funding from the Australian Federal Department of Industry, Science, Energy and Resources will support researchers in ecology, geomorphology, catchment hydrology and computer modelling to collaborate with volunteer citizen scientists engaged in monitoring the region.

The outcome of the project will be an ecosystem analysis and monitoring data that will help inform decision-making and activate on-ground recovery initiatives by land management agencies and the wider community.

The project will target the following:
1. The ecology of the Grose Valley with an emphasis on the Blue Gum Forest.
2. The ecosystem of the Blue Gum Forest – including mapping of understory components.
3. Landform and geomorphology of the floodplain and fluvial movements.
4. The hydrology of the Grose Valley catchment.
5. A detailed survey of the condition of the plateau, woodlands and forests – these having been extremely altered by the recent fire, the past high frequency of fires and erosion causing soil loss, carbon and nutrient loss.
6. The recovery of endangered species will form part of the program including focus on the plant species Isopogon fletcheri, Lieonema lachaneoides and Zieria covenyi.
7. The role of remnant herbivore populations Grey Kangaroo, Red-necked Wallaby, Swamp Wallaby and Common Wombat in the recovery process, and their contribution to reduction of and patch distribution of understory fuel.
8. Health of the recovering swamp and heath communities on the Lycon to Mt Hay Plateau which impact water quality and quality that flows into the Gross valley.
