Wildfire Suppression In Fire Dependent Forests By Jessica Tancordo
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.
