Abstract
Two Peoples Bay Nature Reserve in Western Australia has a long history of ecological studies and adaptive fire management. This provides an excellent opportunity to assess the effects of fire management, including fire exclusion, on the ecosystems and threatened species of an important nature reserve.
To review the fire history of the Reserve and the complexity of managing fire for the conservation of threatened species and communities.
In this paper, we reviewed data from personal consultations, historical records of fire management, analyses of fire regimes, long-term Djimaalup/noisy scrub-bird monitoring, camera-trap surveys, botanical surveys, and quadrat analysis, dating from before to after a large fire in 2015.
Fire sensitive ecosystems at the Reserve are identified. Senescing flora species recruited following the 2015 fire and fire-stimulated species were recorded for the first time. The exclusion of fire was a key factor in the conservation of the Djimaalup/noisy scrub-bird, but has implications for the conservation of other species.
While introduced fire was excluded from the granite headlands for >60 years to conserve fauna habitat, this may not have been an optimal strategy for other conservation dependent fauna, and fire sensitive communities.
The exclusion of fire was an effective management tool for 60 years to conserve fauna habitat, initially driven by conservation of the Djimaalup/noisy scrub-bird, but adaptive management must consider the range of species present as well as a changing climate. Long-term studies and monitoring of threatened species are invaluable to allow informed decisions on adaptive fire management.
Keywords: fire history, fire sensitive communities, habitat management, long-term fire exclusion, noisy scrub-bird Atrichornis clamosus, obligate seeder, strategic fuel reduction.
