Plant Diversity of the Tropical Research and Education Center, University of Florida, Homestead

This dataset (`TRECflora.csv`) and accompanying metadata file (`TRECflora-metadata.doc`) were first presented in the 2018 Proceedings of the Florida State Horticultural Society and updated April 2019, Dec 2022, and Dec 2025.<br><br><i>Abstract</i>. The Tropical Research and Education Center (TREC) is the southernmost campus of the University of Florida and is in Miami-Dade County, FL. TREC is dedicated to research, teaching, and extension in natural resources, agriculture, and ornamental, vegetable, and fruit crops. As part of this mission, a large diversity of cultivated plants was established at TREC, while also preserving native pine rockland and rockdale hammock. The research at TREC includes agroecology, which investigates the production, diversity, and resilience of agricultural systems relative to surrounding areas. Identifying TREC plant species is an important step in establishing this context for agricultural systems. Although many partial lists of vascular plant species have been made for TREC, there had yet been no comprehensive list. We report a comprehensive inventory of plant species completed over the last decade (`TRECflora.csv`). Each plant species was identified with botanical keys and confirmed with online specimens or a previous report from a trusted source. The inventory currently has 895 species including 301 native; 311 established, non-native; 233 non-established, cultivated; and 50 unknowns. We gathered detailed information for each species identified, including plant use, general habitat, weediness, specific location, and identification sources other than the authors. This data supports agroecological research into the effects of plant diversity and surrounding areas on crop physiology and production.

本数据集（`TRECflora.csv`）及配套元数据文件（`TRECflora-metadata.doc`）首次发表于2018年《佛罗里达州园艺学会会报》，并分别于2019年4月、2022年12月及2025年12月完成更新。

摘要：热带研究与教育中心（Tropical Research and Education Center, TREC）是佛罗里达大学最南端的校区，坐落于佛罗里达州迈阿密-戴德县。该中心致力于自然资源、农业以及观赏、蔬菜与果树作物领域的研究、教学与推广工作。为践行这一使命，中心不仅培育了种类丰富的栽培植物，同时还保护了原生松岩地与罗克代尔汉莫克生境。该中心的研究涵盖农业生态学，后者聚焦于探究农业系统相较于周边区域的生产能力、物种多样性与系统恢复力。确定TREC范围内的植物物种，是构建农业系统研究背景的关键一环。尽管此前已针对TREC生成多份维管植物物种的局部名录，但始终缺乏一份完整的综合名录。本研究报告了过去十年间完成的植物物种综合名录（即`TRECflora.csv`）。所有植物物种均通过植物分类检索表完成鉴定，并经在线标本或可信来源的既往文献记录予以确认。当前该名录共收录895个物种，其中本土物种301种、已归化外来物种311种、未归化栽培物种233种，另有50个物种的归属暂未明确。研究团队为每个已鉴定物种收集了详细信息，包括植物用途、生境概况、杂草化特性、具体分布位置，以及除本研究团队外的其他鉴定来源。本数据集可为农业生态学研究提供数据支持，用于探究植物多样性及周边区域对作物生理与产量的影响。
