  2. Do trees have a value?

  3. Reasons for tree appraisal • Settlement for damage or death of plants through litigation • Insurance claims or direct payment • Loss of property value for income tax deductions • Real estate assessment purposes • Agency budget justification • Condemnation proceedings • Sale of nursery property • Establishing values of plants that may be damaged during construction

  4. 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.

  5. Council of Tree and Landscape Appraisers Guide for Plant Appraisal • 1947 – National Shade Tree Conf. and National Arborist Assoc. (NAA) form joint committee • 1957 – Shade Tree Evaluation published • 1970’s – Two revisions incorporated a location factor and a replacement method. Species lists were dropped and inform. on Internal Revenue Service regs. and insurance coverage was added. • 1975 – CTLA established

  6. Factors in Appraisal • Size • Species • Condition • Location – Site/Contribution/Placement

  7. Size • Trees are most commonly expressed by their height or trunk diameter. • Shrubs or small conifers described by height or branch spread. • Nursery plants, size is indicated by trunk diameter, height, branch spread or the size of the container.

  8. Size measured as Trunk Diameter • Trunk diam. less than or equal to 4 inches, measure at 6 inches above ground. • Trees larger than 4 in. diameter, yet a transplantable size, are measured at 12 inches above ground. • Trees to large to transplant are measured at 4.5 ft above ground.

  9. 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

  10. Condition • Structural Integrity • Plant Health

  11. Location • Site

  12. Location • Site • Contribution
