Adequacies and deficiencies of alpine and subalpine treeline studies in the national parks of the western USA

Auteur(s) et Affiliation(s)



Description :
The AA. performed a content analysis on previous research that examined alpine treeline in national parks and classified each treeline study as anthropogenic, orographic/edaphic, or climatic according to the primary factor attributed to treeline control. Results indicated that the 3 types of treeline are not uniformly studied. Climatic treeline is most commonly studied whereas anthropogenic and orographic/edaphic studies are often lacking. Furthermore, several western national parks are entirely devoid of anthropogenic and orographic treeline research. More research in protected places is required to broaden the understanding of multiple treeline processes across both regional and worldwide extents.
