The U.S. Department of Agriculture Forest Service is a Federal agency that manages public lands in national forests and grasslands. The Forest Service is also the largest forestry research organization in the world, and provides technical and financial assistance to state and private forestry agencies. Gifford Pinchot, the first Chief of the Forest Service, summed up the purpose of the Forest Service—"to provide the greatest amount of good for the greatest amount of people in the long run." |

| 4723041 | brown tree snake | Boiga irregularis | The Island of Guam had no snakes of any kind until this species was introduced, probably during the American invasion of Guam in 1944. War material (tanks, trucks, howitzers etc.) were moved to Guam from the New Guinea and Solomon Islands campaigns, and it is likely that some snakes were aboard the equipment. They now number in the millions on Guam, and have been responsible for the extirpation of ten native bird species. This captive snake is about 8 feet long. Brown tree snakes are rear-fang poisonous, and not dangerous to humans larger than baby size. Ca. 1987. |
