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.

• Overstory data collection site establishment
  • Started: 2013-05-15
    Ended: 2013-08-31
    
  • Method Description: 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.

• Plot layout
  • Started: 2013-05-15
    Ended: 2013-06-15
    
  • Method Description: 15 subplots with 4 quarters at each one for a maximum of 60

• Overstory sampling
  • Started: 2013-05-15
    Ended: 2013-08-31
    
  • Method Description: Overstory – point centered quarter data. Ran once for mature (DBH>=10.16cm) and once for sapling (DBH 2.54 – 10.15cm) sized trees and included dead standing trees that reached breast height.
