What role may fire play in ecological succession and how may fire be used in the management of certain ecosystems?
What will be an ideal response?
Periodic fire will favor some species over others, just like any other abiotic limiting factor. Grassland and pine forests are ecosystems that depend upon fire. "Fire is being increasingly used as a tool in the management of" grasslands and pine forests. "In pine forests, if ground fires occur every few years, relatively little deadwood accumulates. With only small amounts of fuel, fires usually just burn along the ground, harming neither pines nor wildlife significantly." In forests where fires have not occurred for many decades, however, deadwood accumulates and if a fire does break out, it will almost certainly become disastrous.
