Hemlock Legacy Project (HeLP) : A paleoecological requiem for eastern hemlock

Auteur(s) et Affiliation(s)



Description :
The loss of eastern hemlock is of particular concern because hemlock is : (1) a foundation species; (2) one of the longest-lived tree species over much of temperate eastern North America; and (3) sensitive to climatic variation and ecosystem disturbance, making it an ideal species for the reconstruction of environmental history. In this progress report, the AA. review the extensive body of science derived from this paleoenvironmental archive and urge scientists from eastern North America to sample and archive old-growth hemlock while living and dead material remain. They describe a community-based approach to salvaging paleoenvironmental archives that could serve as a model for collections from other foundation species currently threatened by exotic forests pests and pathogens (e.g. whitebark pine, ash).
