blbullet.gif (864 bytes)Almost 50% of the entire state of Louisiana is forested (13. 8 million acres).

blbullet.gif (864 bytes)Over 90% of forested acreage in Louisiana is privately owned.

blbullet.gif (864 bytes)The southern pine beetle is Louisiana's most important forest insect pest. In 1995, a significant outbreak affected a large proportion of the State. Beetle populations declined in 1996, but losses continued in the Florida Parishes and the northwestern portion of the State. In 1997, beetle population continued to decline, with 601 SPB spots affecting approximately 109,000 acres. The outlook for 1998 is for populations to increase slightly.

 blbullet.gif (864 bytes)In 1997, the forest tent caterpillar defoliated over 230,000 acres of, primarily, tupelo gum in forested wetlands.

 blbullet.gif (864 bytes)The fruittree leafroller defoliated baldcypress over an area of 525,000 acres in southeastern and south central LA in 1997. Although the predominant impact is loss of growth, repeated annual defoliation has resulted in significant crown dieback and mortality of sapling/pole-sized cypress.

 blbullet.gif (864 bytes)Defoliation of loblolly pines by the loblolly pine sawfly occurred on approximately 3,000 acres in the spring of 1997. Caldwell parish was most heavily affected, with lesser amounts in LaSalle and Winn Parishes.

blbullet.gif (864 bytes)The larger elm leaf beetle again affected approx. 3,500 acres of mixed elms in the Sherburne Wildlife Management Area (Iberville Parish). Wildlife biologists report tree mortality apparent related to the defoliation.

In spite of the relatively good health of Louisiana's forests, a variety of insects and diseases (both native and introduced), and human-caused impacts such as air pollution, continue to threaten the State's resources. To deal with this constantly changing mix of challenges, the Office of Forestry and the Forest Health Protection unit of the USDA Forest Service cooperate to prevent, detect, suppress and manage this multitude of threats. The partnership between the two agencies has worked for three decades to maintain and improve the health of Louisiana's forests.
