National Park Service
The National Park Service manages wildland fire to protect the public, communities and infrastructure, conserve natural and cultural resources, and restore and maintain ecological health.
Cumberland Island exhibits abundant vegetation and wildlife habitat, although much of the island's vegetation was altered by human activities before the National Seashore was established in 1972. In addition, vegetation and habitat have been altered through the general practice of suppressing all wildland fires, which has continued during NPS management on the island.
Longleaf pines are just one important ecosystem found on Cumberland Island. Longleaf pines and associated organisms evolved to not only withstand fire, but to be dependent on it for their survival. In order for longleaf pine seeds to germinate and grow, they must fall on open bare mineral soil, typically cleared by fire. In the absence of fire, pine needles and other forest debris will build up as ground litter and keep longleaf seeds from sprouting. Also, shade from a thick understory can kill longleaf seedlings. If this happens, as the mature longleaf pines die -- at an age of several hundred years -- they are replaced by broadleaved trees, such as oaks or hickories, and the whole ecosystem changes. This is the well-known ecological principle of succession.
Many plants and animals depend on the longleaf pine for their survival, thus making the longleaf pine habitat one of the most diverse habitats found in North America. For example, the gopher tortoises are important, for as many as 300 other animals use their 15-20 foot deep burrows. These include snakes, frogs, foxes, spiders, and beetles.
