Longleaf Pine (Pinus palustris)

The IUCN lists this species of pine tree native to the Southeast United States as endangered, but they say it may qualify as critically endangered if the time frame for assessing the threat level was expanded. The declining population of this species is mostly due to logging.

"Longleaf pine ... was heavily exploited since Europeans settled in the Coastal Plains and served a major forest industry in the region. Its wood is used for sawlogs, stage flooring, plywood, pulpwood and produces poles, fence posts, and piling as it makes straight stems largely free of branches when grown in closed stands. Turpentine and other chemicals can be distilled from the chipped wood," the IUCN says.

This tree likes a warm, humid climate and tends to hug the coastline, but extends into the foothills of the southern Appalachian Mountains.
