• Growth Response of White Spruce [Picea glauca (Moench) Voss] in Denali National Park under Warming Climate

      Bret-Harte, Syndonia; Okano, Kyoko (2012)
      In subarctic mountains such as Denali National Park and Preserve(DNP), vegetation shifts from alpine tundra to boreal forests caused by recent climate change are a potential threat to plant conservation and indirectly to animal habits and diversity, which could affect the experience of visitors who wish to see wildlife.  The growth rate of Picea glauca (white spruce) could decrease by climate change due to drought stress, which might lead to species elimination.  The shift of P. glauca towards a higher elevation would require its seedlings not only to adapt to new abiotic harsh conditions, but also to compete with other plant species that are already present.
