Fire in the Kimberley
July 21st, 2008 by Liz | Click to leave a comment »The Department of Environment and Conservation (DEC) is responsible for management of Western Australia’s State Forests, National Parks, Conservation Parks and Nature Reserves. The Department uses planned fire to manage these natural ecosystems in order to maintain the biological diversity of habitats and species richness, and to protect life, community assets and natural resources from damage by uncontrolled fire later in the season.
Edward Hatherley, Regional Fire Coordinator (DEC) for the Kimberley Region recently sent out the annual notification of the end of the DEC burn program, and I asked him to elaborate on the reasons behind fire in the Kimberley.
“The objectives of the burning is to create fuel reduced buffers that may limit the extent of wildfires and create a mosaic of different age vegetation that will assist in maintaining the biodiversity of the area. DEC also works closely with adjoining stakeholders in the interest of developing a strategic fire plan to address the issue of large late dry season wildfires that are having a significant impact across the Region. Generally DEC operations run over a 12 week period commencing around April 2008 through to late June and an aircraft may be used to ignite these burns.
Over the past 12 months an increased number of DEC resources have been directed towards engagement and training of indigenous people in order to increase capacity and knowledge across the Kimberley region. DEC, with the assistance of the Kimberley Land Council (KLC) is actively engaging and involving Traditional Owners in the planning and implementation of its prescribed burning program. This has been a significant step towards engaging aboriginal people in how fire is managed across the Kimberley.
DEC has been developing its fire program to include “landscape mosaics” or “patch burning” as well as strategic buffers. Such burning allows for mosaics of burnt and unburnt patches to be developed in the landscape. Mosaics in the landscape provide refuge for native fauna during late fires, strategic buffers are designed to try and limit the size of large fires. Fires lit in the early part of the dry season are generally less intense, and of a more “patchy” nature owing to the diversity in vegetation structure, curing rates. Fires that burn late in the dry season consume a greater percentage of the combustible vegetation, run for several weeks, and burn under far more extreme intensity and conditions.
- Mosaic burn pattern
- Cool, early Dry Season fire
- Hot, Late season fire
In 2008 we also saw the further development of a close partnership with “Ecofire” a National Heritage Funded project aimed at strategic fire management of Pastoral leases. DEC’s prescribed burning program which covers the conservation estate, unallocated Crown Lands and some Aboriginal Lands surrounding the Ecofire project area, was closely aligned to ensure truly strategic approach. This aims to limit the size and extent of wildfires, which impact on the Kimberley Region each year.
For the second year in a row the Kimberley received widespread rainfall in June with falls of up to 47mm being recorded. This rainfall not only promotes the quick recovery of the early dry season fire areas, but has the added advantage of extinguishing most fires across the Region, effectively creating a distinct end to the Prescribed Burning Season.
Fire is and always has been a part of the Kimberley environment, however the contemporary regime of large, intense, late fires are impacting on the ecological and aesthetic values of the Region. With vast inaccessible areas, limited resources and a fire prone environment the best approach is to work strategically with all stakeholders towards a mutual outcome.”
