Tips for Conducting a Mast Survey
1. Consider only species listed and only trees with dominate or co-dominate crowns large enough to produce nuts.
2. Examine a minimum of 50 trees in a county. Ideally, include information from several woodlots in the same county.
3. Use binoculars if possible. Scan each tree and evaluate the crop in each as to relative abundance.

HEAVY: Nuts in clusters evenly distributed, entire tree bearing nuts.
MEDIUM: Some clusters with scattering of single nuts evenly distributed over the entire tree or clusters of nuts only on half of the crown.
LIGHT: Scattering of single fruits over entire tree or a few clusters in 1/4 of the crown.
FEW TO NONE: Less than two dozen nuts on entire tree.
