Evaluate longleaf pine seedling container sizes and types, field nutrition trials, and influence of prescribed fire on seedling physiology.
Assess the effects of prescribed fire, herbicide application, and fertilization on the growth and stand structure of young longleaf pine plantations. Assess the effects of harvesting and regeneration practices on long-term productivity of pine stands through multiple rotations.
I am currently working with Susana Sung (Southern Research Station), Mary Anne Sayer (Southern Research Station), the Texas-Louisiana Longleaf Pine Taskforce, and the Kisatchie National Forest to help restore longleaf pine on private and government lands.
Why This Research is Important
Longleaf pine ecosystems are essential for the preservation of hundreds of plants and animals dependent on them for quality habitat. Currently, longleaf pine forests cover only 4.2 million acres across its native range from East Texas to Virginia. With our best efforts, it is hoped that 8 million acres of longleaf pine will eventually be restored. Most of these additional tracts will have to be on private lands. Longleaf pine forests provide a unique set of values that are of interest to private landowners. It is more windfirm than loblolly or slash pine. It grows on droughtly low nutrition sites where loblolly and slash pine are less productive than longleaf pine. It is fire tolerant and is the species of choice in arson-prone areas. It can be managed easily with fire to provide open forest habitat for many animals that require low brush and herbaceous plant cover. Longleaf stands produce a higher percentage of utility poles than other southern pines, and poles are a product that maintains it value even in poor timber markets. Longleaf stands also produce other preferred market goods such as pine straw for landscaping and weaving of high quality baskets, native herbs, high end furnishings and furniture, and forage for livestock. Landowners who desire values other than maximizing wood fiber production may want to regenerate with longleaf pine.

1978 - Current
I have conducted silvicultural research for the Southern Research Station in Pineville, Louisiana since 1978. Initially, I worked with herbicides to control vegetation in lobolly and slash pine stands. I also conducted research on mechanical and chemical site preparation methods, and the use of fertilizers to boost loblolly and slash pine growth. In 1990, I initiated a cooperative research program with the Kisatchie National Forest on the use of prescribed fire in longleaf pine stands. That work continues, and has expanded to include how the establishment of high quality nursery-grown seedlings leads to better survival and boosts sapling longleaf pine development and how nutrient amendment and prescribed fire affect seedling and sapling longleaf pine physiology and growth.
