Methods
The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Current Methods
Tree metrics
Started: 1988-06-01Permanently tagged trees are evaluated annually for crown condition, injury to bole and crown, taphole closure, seed production, regeneration and early and late season defoliation. Plot consists of 5 subplots, 20 X 20 m size. Trees are permanently tagged. Protocols follow international NAMP methods manual.
Past Methods (No longer in use)
- Injury assessment after ice storm
Started: 1998-01-30
Ended: 1998-06-01In 1998, special spring survey was conducted to assess injury from the January ice storm. Addition of regeneration counts was also added.
