History of Plant Appraisal Bible – 1st recorded documentation of and effort to
place a value on a tree. 1901 Univ. of Mich. - $5 + compound interest at 5%
for 25 years. 1900’s Univ. of Mass – Dr. George T. Stone –
calculate tree values based on their size, location and condition.
1930’s Dr. E.P. Felt, director of Bartlett Tree Research Lab further refined Dr. Stones technique. This method considered species and residential land values in addition to size, condition and location.

Species
Ratings vary geographically Judged by aesthetics and general
functional value, climatic and soil tolerances, resistance to insects and diseases, growth characteristics, maintenance requirements and allergenic properties.
NDUCFA developed ratings for ND
