Above the treeline, fire is less common than in foothill forests. Post-fire recovery times also tend to be shorter  because of the dual influences of low flammability traits coupled with the fact that most alpine plant species exhibit strong resprouting strategies that have evolved in response to harsh climate conditions . However, fires in alpine treeless landscapes can still have long-term and catastrophic impacts on fire-sensitive vegetation types such as groundwater-dependent wetlands dominated by hygrophilous plants and peat soils . Similar impacts can be severe on long-lived, slow-growing vegetation such as coniferous heathlands  and highly restricted and threatened fauna  that depend on these plant communities . Such fires have even been found to significantly impact sub-alpine treeline mortality rates  and in some cases have resulted in treelines shifting to lower elevations .
