1977. Rare and local trees in the National Forests. U.S. Dep. 

 Agric, Conserv. Res. Rep. 21, 14 p. 



The National Forests contain and preserve trees of many species 

 that are classed as rare or local in distribution within the country. 

 These include 40 species and several varieties within continental 

 United States and 90 tropical tree species within the Caribbean 

 National Forest of Puerto Rico. Nine tree species and 6 additional 

 varieties on preliminary lists of proposed endangered and threat- 

 ened plant species of continental United States grow wild within 

 National Forests. This report is the third in a series on rare and 

 local trees.
