In our study, only a fuel load (dry litter or dead material) similar to natural levels found in the Fynbos biome was used (van Wilgen et al .…”

Fire is an important environmental disturbance in Mediterranean-climate regions; however, its intensity and frequency are predicted to increase under climate change scenarios with unknown implications for ecosystems in these regions. Temporary wetlands, with their periodic wet and dry phases, are considered one of the most productive systems in the world and their invertebrate communities form a crucial diet component for higher trophic levels. The effect of fire on the hatching success of invertebrate propagules from temporary wetlands in the Cape Flats Sand Fynbos (Cape Town, South Africa) was investigated. Homogenised soil samples from these wetlands were either experimentally subjected to vegetation fires (treatment samples) or were left as is (control samples). The results revealed that fire had a significant negative impact on invertebrate hatching success, as revealed by analyses of the different diversity measures (e.g. taxon richness, Shannon diversity and Pielou's evenness) and community composition. Proper management of fire, especially in the Mediterraneanclimate regions, which replicates the natural fire intervals typical of the area (10-15 years) and avoids unregulated or accidental fires, is essential to ensuring future protection of these critical biodiversity hotspots created by the temporary wetlands.

Understanding species’ responses to fire regimes, particularly rare or threatened species, is important for land managers tasked with managing for biodiversity. Hickman's Allanaspides (Allanaspides hickmani, Anaspidesidae) is a rare, primitive, shrimp‐like crustacean, with high conservation value. It is restricted to a single catchment in the island state of Tasmania, Australia, where it occurs within moorland pools typically containing crayfish (Ombrastacoides spp.) burrows. Although its moorland habitat has a long history of firing, adverse fire regimes are a potential threat to the species. A large part of its range is subject to planned burning to help manage the detrimental effects of high‐intensity wildfires. The resilience of A. hickmani to low–moderate‐intensity fires was investigated over 13 years using a replicated before‐after‐control‐impact design. The fires resulted in an initial reduction in vegetation cover and surface water and an increase in water temperature. There was no effect of fire on A. hickmani captures 4 months after small‐scale, low‐intensity autumn burns. However, 5 months later, following an unintended larger‐scale, medium‐intensity spring burn, there was an 80–90% reduction in A. hickmani captures and their numbers did not recover until 6–9 years post‐fire. It is not known whether the reduced catch was due to a reduction in the number of A. hickmani or their movement from pools into crayfish burrows. These findings together with evidence of a varied fire history, including high‐intensity wildfires, within their range suggests that A. hickmani and its habitat are resilient to a range of fire frequencies and intensities provided that the fire regime does not degrade or lead to a complete loss of peat. Climate change predictions for warmer and drier summers in western Tasmania will increase the risk of peat loss. Planned burning is likely to be important for the protection of A. hickmani habitat from predicted adverse fire regimes.
