Raw dataset 14.01.2024 Frediani, Rogers, Screech (2024) University of Dundee Botanic Garden Tree Asset Valuation Report: An i-Tree Eco and CAVAT assessment.

This dataset contains the full tree inventory and associated ecological measurements collected for the University of Dundee Botanic Garden Tree Asset Valuation Report: An i‑Tree Eco and CAVAT Assessment (Frediani, Rogers & Screech, 2024). The dataset was prepared in accordance with the i‑Tree Eco v6 field protocol and includes all variables required for model processing, valuation, and ecosystem services estimation.The dataset comprises:Tree‑level structural data Species identification, DBH measurements, total height, crown dimensions, crown light exposure, crown condition, percent dieback, and land‑use classification.Health and condition indicators Observations of pests, diseases, defects, and management needs, following i‑Tree Eco condition rating categories.Location and plot information Plot identifiers, GPS coordinates (where applicable), and site characteristics relevant to model calibration.Ecosystem service inputs Variables required for estimating carbon storage and sequestration, air pollution removal, avoided runoff, and other ecosystem services.CAVAT valuation inputs Stem diameter, functional value scores, and site‑specific adjustment factors used to calculate Capital Asset Value for Amenity Trees (CAVAT).Derived outputs (where included) Pivot‑table summaries, species composition analyses, structural metrics, and valuation summaries used in the report.Purpose of the dataset: To support the assessment of tree structure, condition, and ecosystem service value within the University of Dundee Botanic Garden, and to provide a transparent basis for the i‑Tree Eco and CAVAT analyses reported in the 2024 publication.Relation to the publication: This dataset forms the empirical foundation for all quantitative findings in Frediani, K., Rogers, K., & Screech, K. (2024). University of Dundee Botanic Garden Tree Asset Valuation Report: An i‑Tree Eco and CAVAT assessment. It includes the raw measurements and classification data used to generate the ecological and economic valuations presented in the report.Format: Microsoft Excel workbook (.xlsx), containing raw data tables, lookup sheets, and pivot analyses.Provenance: Data were collected by trained surveyors following the i‑Tree Eco protocol during the 2022–2024 survey period. The dataset was cleaned, validated, and prepared for analysis by the authors.
