Leslie Holdridge arboretum tree census, La Selva Research Station, Organization for Tropical Studies, Sarapiquí, Heredia, Costa Rica, 1972-2017.

This database is a collection of dendrometric and structural measurements for all the trees in the arboretum, it was compiled through the assessment of 10 census from 1972 to 2017 by O. Vargas and E. Castro for the Organization for Tropical Studies.
The 3.5-hectare Holdridge Arboretum is located at La Selva Research Station. Leslie R. Holdridge, the original owner of the property, created the arboretum in 1968. Initially, it was a small cacao grove with an exceptionally rich overstory of native shade trees. To facilitate research in the arboretum, staff later removed the cacao. In 1970, Gary Hartshorn continued to plant seedlings of many native tree species. OTS continues to plant, tag, and measure trees. OTS maintains the arboretum by regular mowing and pruning to facilitate safe access. Courses, natural history visitors, students, and researchers use the arboretum for a wide range of observational studies, manipulations, dendrological practices, and taxonomy classes.

本数据集收录了该树木园（arboretum）内所有林木的测树学度量（dendrometric）与结构特征数据，由O. Vargas与E. Castro于1972年至2017年间针对热带研究组织（Organization for Tropical Studies，OTS）开展的10次普查评估整理编制而成。
这片占地3.5公顷的霍尔德里奇树木园（Holdridge Arboretum）坐落于拉塞尔瓦研究站（La Selva Research Station）。该园地的最初所有者莱斯利·R·霍尔德里奇（Leslie R. Holdridge）于1968年创立了这座树木园，其最初为一片小型可可种植园，原生遮荫树种的上层林冠极为繁茂。为便于在树木园内开展研究，后续工作人员移除了园内的可可植株。1970年，加里·哈茨霍恩（Gary Hartshorn）继续栽种了诸多本土树种的幼苗。热带研究组织（OTS）持续开展林木栽种、标记与度量工作，并通过定期割草与修剪维护该树木园，以保障通行安全。各类课程、自然历史研学访客、学生与研究人员均可利用该树木园开展各类观测研究、操控实验、树木学实践以及分类学课程相关活动。
