Trees

Pine

     Pine trees are a common evergreen in this forest.  There are about 115 species of Pines world wide.  They can grow in a variety of environments including poor soil conditions.  Their needles help them to survive in arid conditions by minimizing evaporation.

     The Monterey Pine in California, Pinus radiata, is seriously threatened by an introduced fungal disease, Pine Pitch Canker.  This has left them very sensitive to dry periods causing a browning and loss of needles.  Another problem in North America are the Mountain pine beetles.  They inhabit the Ponderosa Pine, Lodge-pole Pine, Scots Pine and Limber Pine.  They normally only attack trees under stress or poor site conditions.  If the environment  is compromised or population of the beetles increase they will attack the larger trees.

     My belief is that global warming, water and air pollution are major factors in hurting this sensitive ecosystem.  My hope is we will change our ways and stop the decline before we only have pictures.
