Distribution of slash pine as related to certain climatic factors

Abstract

THE CONCEPT THAT CLIMATE determines the geographic distribution of vegetation is generally accepted among ecologists. Seasonal variations in temperature and rainfaII are considered the most important climatic factors limiting the geographic distribution of a given species (Daubenmire, 1956). Because of its rapid growth and value for timber and naval stores, slash pine ( Pinus elliottii Engelm.) is one of the most important commercial tree species in the southern pine region. Most of the seedlings planted in reforestation programs in the South are slash pine (Mergen, 1955). The natural range of the species extends from southern South Carolina westward through the Atlantic and Gulf Coastal Plains to eastern Louisiana, and southward to the Gulf of Mexico and central Florida. Seed source and racial studies indicate that slash pine is susceptible to variations in climatic conditions even within its natural range, but the species has been successfully grown in some areas outside of, hut ad jacent to, its natural range (Hebb, 1955).
