Tree Valuation and Ecosystem Services Analysis

The contract requests the valuation of lost trees using the trunk formula method to determine their monetary worth, focusing on trees that have been removed or damaged. Alongside this, it requires an estimation of the lost ecosystem services provided by those trees, including carbon sequestration, air quality improvement, shade provision, and aesthetic value. The work must be grounded in accepted arboricultural and environmental economics standards to ensure accurate and defensible calculations that reflect the true ecological and economic impact of the loss. This is a subcontract under the NAICS code 541620, tied to the Public Works agency in Pennsylvania, with a response deadline of July 21, 2026. The project is intended to support municipal planning or restoration efforts by quantifying the non-market benefits树木 provided before their removal, allowing for informed decision-making and potential compensation or replanting initiatives. Although specific location details are not provided, performance is expected within Pennsylvania, and the analysis must be comprehensive enough to serve as a basis for policy, reporting, or legal purposes related to urban forestry management.
