Mountain Hemlock (Hm)

This species is important in reforestation of coastal and southern interior wet high elevation forests, although it is susceptible to drought, Armillaria, and branch and stem breakage from the combined effects of snow and vegetation. The major limiting factors that stock type selection can address for Hm is vegetative competition and snowpress. Hm may have a higher incidence of foliage disease than other species due to the tender shoots and dense foliage. It may be better to order larger container types to minimize the problem.
