In the Beginning Early settlers and Native Americans used fire as land
management tool.
Severe fire seasons in the 20th century brought about policies that suppressed every fire that started, but later policies would change.
As wildfire suppression continued, natural fuels from dense amounts of leaf litter and duff layer built up causing wildfires to be even greater when they occurred.
Prescribed Burning Firefighters start and observe fires in order to allow fire
dependent forests to have a chance at regrowth.
Benefits in reduction of hazardous fuels, allows germination of plants, improves wildlife habitat, disposal of logging debris, disease control, and possible decrease in non-native plant species.
Pine Pocosins Coniferous, pyrophitic woodlands
Found in SE Virginia, North Carolina, and NE South Carolina
High and Low Pocosins
Forest consists of Pond Pines and very dense shrubs with large amounts of peat.
Pine Barrens Found in NE United States from NJ to ME
Home to plants such as Pitch Pine, Jack Pine, Wild Lupine and Scrub Oak
Grasslands Shrublands- typically dry and prone to accumulations of
highly volatile fuels
Grasslands- burns readily because fire has to go through stems and leaves of herbaceous plants, lightly heats soil allowing for decomposition and recycling of nutrients.
Savannas- herbaceous level with little to no mature trees, fires suppress tree growth but allow for open landscapes.
