Florida Forest Facts
 

blbullet.gif (864 bytes)Over 40% of Florida is forested (more than 14.6 million acres).

blbullet.gif (864 bytes)Over 80% of forested acreage in Florida is privately owned.

blbullet.gif (864 bytes)The National Forests in Florida (1,029,500 acres) provide recreational and wildlife benefits as well as timber products and jobs for thousands of people.

blbullet.gif (864 bytes)Emphasis on short-rotation management with artificial regeneration (tree planting) on privately owned land means that there is a constant and high demand for healthy seedlings. There were no significant pest outbreaks reported from any of the 7 forest tree nurseries, though, routine monitoring did detect low level activity for several common nursery pests.

blbullet.gif (864 bytes)Starting in 1997, Florida experienced an unusual southern pine beetle (SPB) outbreak that occurred in Marion and Levy Counties (near the cities of Ocala and Silver Springs). This is the farthest south that SPB has been documented within the state, yet 1997 had record setting losses for the state. SPB killed almost 8,000 acres and the outlook is for continued problems.

blbullet.gif (864 bytes)The incidence and magnitude of pine engraver beetle infestations increased from October to December 1997, following an unusual and prolonged drought. Infestations were larger and more prevalent in stands that had been recently thinned.

blbullet.gif (864 bytes)Florida also experienced tree defoliation by pine sawflies, forest tent caterpillar and the cypress looper in 1996. Each of these outbreaks caused public nuisance, landowner concern, tree growth loss, but only limited mortality. The defoliation by forest tent caterpillar is continuing in 1997.

The Florida Division of Forestry
and USDA Forest Service

In spite of the relatively good health of Florida's forests, a variety of insects and diseases (both native and introduced), and human-caused impacts such as changes in land use patterns, continue to threaten the State's resources. To deal with this constantly changing mix of challenges, the Division 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 Florida's forests.
