Western hemlock
Tsuga heterophylla (Raf.) Sarg.

Distribution and Protected Areas – from Hamann et.al. 2005

Conservation Status Summary – from Krakowski et. al. 2009

“Western hemlock is well represented in all levels of protection with the exception of inter situ trials containing Maritime high SPU material. Additional protection and sampling from outlying and remote populations at the margin of the species’ range would add more comprehensive representation to all aspects of hemlock genetic conservation. Periodic seed testing and replenishing ex situ reserves should be a component of this species’ genetic conservation to mitigate the effects of seed deterioration.”
