Alpine vascular plant biodiversity at Spray Park, Mount Rainier National Park
Status and trendIn 2012, we were able to confidently relocate five of the eight pairs of transects sampled in 2002. Along these transects we recorded the same data that we collected in 2002 (e.g., percent cover of all vascular plant species in 20cm x 50 cm quadrats every 5m (Fig. 1), elevation, slope, substrate, and stability). In 2013, we plan to analyze the data making comparisons between the 2002 and 2012 data to see if there have been any changes in vegetation along the sub-alpine and alpine transition zone in Spray Park over the past decade.
DiscussionLong term ecological data can provide insights that short term data may not capture. The data gathered from this decade long comparison of plants at Spray Park will enable us to better understand how vascular plant distributions are changing (or not) in response to a changing climate. This information will help park staff to make more informed management decisions in the face of global climatic change.
