Mangrove Coast Collaborative Project, Post-hurricane Irma mangrove forest structure data, Rookery Bay NERR, February 2022 - March 2023

The dataset describes the structure, composition, and condition of mangrove forests in Rookery Bay National Estuarine Research Reserve (NERR) assessed Feb 2022 - Mar 2023, approximately 5 years post Hurricane Irma (2017) and concurrent with Hurricane Ian (Sep 2022). The dataset includes information on each stem greater than or equal to 1 cm DBH (diameter at breast height) rooted within 69 100 m2 circular plots. Information collected includes site ID, location, species, DBH, status (live or dead), damage associated with the hurricane, presence/absence of regrowth, presence/absence of adventitious roots, whether or not stem is part of a multi-stemmed individual, and the canopy conditions (whether the tree has a canopy or is only sprouting at the base of the tree or trunk). This dataset is associated with the Mangrove Coast Collaborative project (2020 - 2024).

本数据集记录了2022年2月至2023年3月期间，对罗克利湾国家河口研究保护区（Rookery Bay National Estuarine Research Reserve，缩写NERR）内红树林的结构、组成与健康状况的调查评估结果。此次调查距2017年艾尔玛飓风（Hurricane Irma）过境约5年，且与2022年9月的伊恩飓风（Hurricane Ian）发生时段重合。数据集涵盖了69个100平方米圆形样地内，所有胸径（DBH，Diameter at Breast Height）≥1厘米的木本茎干的相关信息。采集的调查指标包括：样地编号、地理位置、物种名称、胸径、存活状态（存活或死亡）、飓风相关损伤情况、萌枝存在与否、不定根存在与否、该茎干是否属于多茎个体，以及冠层状况（树木是否具有完整冠层，或仅在树干基部萌发新枝）。本数据集隶属于2020-2024年的“红树林海岸协作项目”（Mangrove Coast Collaborative）。
