Abstract:
Includes the metadata and inventory measurement data for all TSQs of Site A and B recorded in separate campaigns of TreeDì cohort two and three in 2023 and 2024 respectively. The data includes the positions, species and conditions of shrub and tree individuals of each TSQ. Additionally inventory measurements of shrubs and trees are included.
Design:
A TSQ ideally consists of four adjacent trees in a 2x2 pattern, with a shrub in the middle. TSQs were selected based on a set of target shrubs. Namely Ardisia crenata, Camellia chekiangoleosa, and Distylium myricoides on Site A, and Distylium buxifolium and Viburnum setigerum on Site B. TSQs were then selected to cover the shrub and tree diversity range and have as many alive tree members as possible. Also a set of no-shrub and no-tree TSQs were selected. In total 284 TSQs have been selected. 151 on Site A in 2023 and 133 on Site B in 2024. All TSQ individuals were then determined and measured. Namely diameters or circumferences were determined for trees at 10 and 130 cm and for shrubs at basal height. Additionally maximum height and crown width via two perpendicular measurements was determined. For the detailed measurement procedure, please refer to the attached protocol

Dataset column
Name:
measurement_num
Definition:
If there are multiple measurements of the same type for the same individual this column gives them a unique number. E.g. multiple DBH measurements in case of a multi-stem tree. There is also a total row for individuals where multiple measurements are present. Dead or missing individuals still have a total row, where they could theoretically be present (not on control plots).
