TREES AND SHRUBS IMPORTANT TO WILDLIFE 



Alaska's 30 species of trees, along with many of its shrubs, are important 

 to wildlife. Visitors will find relatively few unfamiliar trees. All ex- 

 cept three scrubby willows and two paper birches occur also in some other 

 part of the United States. Nineteen of them grow wild in parts of Cali- 

 fornia, and seven are widely distributed in the "north woods" across 

 Canada and south into the northeastern United States. The following 

 list is from the United States Forest Service's Pocket Guide to Alaska 

 Trees, Agriculture Handbook No. 5, United States Department of 

 Agriculture.
