Florida torreya [Torreya taxifolia]

Florida torreya is a cone-shaped evergreen tree native to the bluffs and ravines of the Apalachicola River Valley. It reaches a mature height of 18 meters (59 ft.), and has whorled branches. Stiff needles emit a pungent odor when crushed, hence the common name "stinking cedar". Dark green seeds mature from midsummer to autumn. The pollen cones and ovules grow on separate trees, which reach sexual maturity after about 16 years.

The deep river system of the Apalachicola River Valley begins in the headwaters of the Appalachian Mountains. This valley creates a unique and isolated environment that is characterized by a cool, moist climate. Florida torreya grows in the ravines along the eastern side of the valley from Lake Seminole in Georgia to Bristol in Liberty County, Florida. The Georgia population consisted of 27 trees in 1981 and is contained on public land. In Florida, populations occur on both public and private lands. The Torreya State Park and a city park in Chatahoochee protect Florida torreya and other native species. An isolated population occurs near Dog Pond, west of the Apalachicola River on private land.

Disease is the most prominant threat facing Florida torreya. Housing development, dams, and reservoirs also pose a threat to this species but the steepness of the bluffs and revines limit building capabilities. The Fish and Wildlife Service (FWS) is carefully monitoring this species and research projects are investigating disease prevention.
