Current Methods
Recording and monitoring methods
Developmental stages for sugar maple are recorded based on a published guide. Guidelines for monitoring developmental stages for other species were developed as part of this project.
Specimens
Started: 1991-04-01Five healthy dominant or codominat trees and five saplings used as replicates.
Started: 1991-04-01Sugar maple monitored at Proctor Maple Research Center.
Started: 1992-04-01Three hardwood species (sugar maple, yellow birch and American beech) monitored at two elevations (1400 and 2200 ft.)
Started: 1995-04-01Red maple and white ash added in 1995, at 1400 ft., only.
Started: 1996-04-01Upper elevation site discontinued.
Started: 1996-04-01Yellow birch and American beech monitoring discontinued in 1996.
Visual ratings
Started: 1991-04-01Visual ratings of bud development are made twice weekly on each tree and sapling using a high powered spotting scope. Developmental stages are recorded for 10 buds per tree. Flower bud development is recorded separately from vegetative buds.
Added data collection from randomly selected regeneration of each species to compare to permanently marked regen. Plan is to replace the permanently marked regen with random sampling in the future.
Started: 2003-04-01Only sugar maple trees are monitored; discontinued red maple and white ash.
