The long-term implications of a warmer global climate, coupled with more frequent and/or severe fires in mountain ecosystems, are expected to be transformative for mountain biota. Fire-sensitive montane forests, such as Australia's alpine ash , are expected to become highly susceptible to population collapse and local extinction as intervals between fire events contract and become too short for species to reach reproductive maturity -an impact that will likely be further exacerbated by recruitment failure caused by post-fire drought and moisture deficiencies . Fire and climate change are also likely to act synergistically in mountainous ecosystems, via positive feedbacks that increase fire frequency by changing vegetation composition to more flammable fuel types, thereby increasing landscape susceptibility to future fire . More frequent fires in these ecosystems will also exacerbate native and exotic species invasions , faunal population declines , poor air quality  and soil erosion and landslide risk  and reduce freshwater catchment volumes and quality , all of which will impact negatively on human health and well-being .
