This is a low impact research project that involves a) vegetation surveys to characterize forest overstory structure (tree id, height and diameter) and understory composition (tree seedlings and herbaceous cover); b) measurements of long term stand microclimate using iButton data loggers and c) extracting tree cores to study how climate affects tree growth and mortality.

  • dataset_eml_methoddescription: At each site (i.e., elevation) a sampling transect with 15 points each separated by 15 meters was established parallel to the elevation contour. At each point the point-centered-quarter method was used for sapling (2.54 – 10.15cm DBH) and mature (>10.15cm DBH) living and dead individuals.
