During the most severe burning conditions practically all of the living understory vegetation on pocosins may be consumed by fire (9). Even under less severe conditions leaves and branch tips are readily consumed. Whether the moisture content in the living vegetation is high, as it is in the spring, or low, as in the winter, exerts a strong influence on fuel flammability and fire behavior. The moisture content in live pocosin fuels is generally higher than in dead fuels; however, the moisture content of individual plant species and the seasonal moisture changes are not known.

The fire problem in the organic soil (pocosin) areas of eastern North Carolina centers a round the frequent and costly blowup wildfires occurring there and the use of fire as a management tool. Under certain combinations of fuel and weather, low intensity fires will suddenly and often unexpectedly multiply their rate of energy output many times . In almost all instances these fires have been virtually uncontrollable until the weather has moderated or the fire has run out of fuel. Efforts at control are often greatly hampered by inaccessibility and the poor soil trafficability in much of...

Our knowledge of successional relations in tidewater river swamps is scant. In an effort to increase our knowledge, the vegetation in a virgin stand of baldcypress (Taxodium distichum), swamp tupelo (Nyssa sylvatica var. biflora), and water tupelo (N. aquatica) was compared with the new growth in an adjacent 8-year-old clear-cut. area in the Chowan River swamp in Hertford County, North Carolina. The soil, a dark brown muck, was 6 to over 10 feet deep, and numerous buried trees made it difficult to measure depth to the sandy clay loam subsoil. Estimates of the organic matter, using the loss...

The Blacklands occur in two areas of Mississippi, the northeastern and east-central parts. They are found within the much larger Coastal Plains land area, but because of their prairie-like nature and characteristic color, they are grouped separately.
