Biology

Estimate the monetary value of a landscape tree using the Council of Tree and Landscape Appraisers (CTLA) trunk formula method.

Formula

Value = (π × r²) × base cost × condition% × location%
  • CTLA Trunk Formula Method: trunk cross-sectional area × replacement cost × condition × species/location factors.
  • Basic cost per sq in represents replacement cost of an equivalent nursery tree.
  • Condition rating: excellent 100%, good 70–90%, fair 40–70%, poor <40%.

12-inch DBH tree, good condition

Inputs
  • Trunk Diameter (DBH): 12 in
  • Basic Cost per sq in: 27 $/sq in
  • Tree Condition Rating: 70 %
  • Location/Species Factor: 80 %

Area = π×36 ≈ 113 sq in. Replacement = 113×27 = $3,051. Appraised = $3,051 × 0.70 × 0.80 ≈ $1,709.
