The CFS does not have
a G&Y program.
… but …

We do have:




G&Y expertise;
Data/models on stand dynamics
associated with insects and diseases;
Long-term silvicultural trials;
National Forest Inventory (NFI);
Strong emphasis on carbon stocks and
carbon dynamics.

relative categorical frequencies. Environmental Monitoring and
Assessment 105: 391-410.
2002. An inverse gaussian distribution of tree frequencies based
on tree size. Environmental and Ecological Statistics 9: 27-42.
2002. Evaluation of probability proportional to predictions
estimators of total stem volume. Canadian Journal of Forest
Research 32: 92-102.

National Forest Inventory (NFI):




Designed for 10-yr monitoring interval
photo-plot and ground-plot
components
20-km grid for 2 km x 2 km photoplots
Ground plots at 8% of sites, in
support of CCFM C&I, C budget
monitoring, etc.
