Seed Size & Predation

Among their many benefits, prescribed fires can protect southeastern pine woodlands from encroachment – the process of fire-sensitive species expanding into fire-maintained woodlands. Because fire is important for longleaf pine regeneration, forest researchers have studied the effects of flammability on the pine woodlands. In a recent study published in in Applied Vegetation Science, USDA Forest…  More 

Guidelines for Producing Quality Longleaf Pine Seeds

High-quality longleaf pine seeds are essential for producing nursery seedlings that perform well in the field, but producing them is not as easy as it might seem. Longleaf pine seeds are unusually sensitive to damage during collection, processing, treatment and storage. In 2002, Jim Barnett, then project leader for the U.S. Forest Service Southern Research…  More 

The Complexities of Longleaf Pine Cone Production

“Longleaf pine forests are among the most important ecosystems in the southeastern United States,” says U.S. Forest Service research ecologist Qinfeng Guo. “However, they have declined dramatically since European settlement and are considered endangered.” Longleaf pine ecosystems once covered an estimated 80 to 90 million acres across the southeastern U.S. – from Virginia to Texas – but…  More 

The Problem with Longleaf Pine Seeds

Do the Math In 1963, from his work on the Escambia Experimental Forest (Escambia), U.S. Forest Service research forester (now emeritus) Bill Boyer developed the formula for longleaf pine seed dispersal that became one of the foundations for the natural regeneration of the species. Natural regeneration—literally allowing seedlings to sprout wherever seeds fall— seems the intuitive choice…  More
