Current Methods
Plot establishment
Started: 1991-05-01One plot established at Proctor Maple Research Center in 1991.
Started: 1992-05-01Eight plots on west slope of Mt. Mansfield paired at 4 elevations: 1400, 2200, 3000, and 3800 feet. Used to assess changes in crown condition, injury to crown and bole, growth, regeneration, understory cover.
Started: 1990-05-01One plot established in the Lye Brook Wilderness Area as part of the National Forest Health Monitoring Program at 2300 ft.
Started: 1994-05-01Four plots in the Lye Brook Wilderness Area paired at 1400 and 2300 feet, in addition to the NFHM plot at 2300 feet.
Started: 1997-05-01Six plots established in 1997 on the east slope of the mountain in Ranch Valley paired at 1400, 2200, and 3000 feet.
Past Methods (No longer in use)
- Ice storm effects
Started: 1998-01-30
Ended: 1998-06-01In 1998, conducted special spring survey on plots affected by the January ice storm. Measurements included bole breakage and crown loss (%).

Start Date End Date Note Date Entered 2017-11-29 00:00:00 2017-11-29 23:59:59 Counts from 1991 to 2013 were entered into the CountClass2 field because they followed a protocol that counted conifers if they were taller than or equal to 6 inches in height and hardwoods if they were taller than or equal to 12 inches in height. From 2014 to 2016 seedlings were counted as a whole without consideration for classes based on height. In 2017 a different protocol was followed where seedlings were broken down by Class1 (Conifer =12 in tall). 2017-11-29 10:39:52
