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.<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, fruit, and biofuel 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 mission of TREC was recently expanded to include agroecology, which investigates the production, diversity, and resilience of agricultural systems relative to surrounding areas. Identifying TREC plant species is a first step in establishing this context for agricultural systems. Although many partial lists of vascular plant species have been made for TREC, there has been no comprehensive list. We report a comprehensive inventory of plant species diversity 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 707 species including 240 native; 237 established, non-native; 190 non-established, cultivated; and 40 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 will support agroecological research into the effects of plant diversity and surrounding areas on crop physiology and production.

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、农业以及观赏植物、蔬菜、水果与生物燃料作物领域的研究、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，同时还保护了原生的松岩地（pine rockland）与罗克代尔林隙地（rockdale hammock）。该中心近期拓展了使命范畴，新增农业生态学研究方向，该方向旨在探究农业系统相较于周边区域的生产能力、物种多样性与恢复力。明确TREC的植物物种名录是构建该农业系统研究背景的首要步骤。此前虽已针对TREC生成多份维管植物物种的部分名录，但尚无完整全面的官方名录。本研究报告了过去十年间完成的全面植物物种多样性清查成果，对应数据集为`TRECflora.csv`。所有植物物种均通过植物分类检索表进行鉴定，并借助在线标本或权威来源的既往报告完成确认。当前该清查名录共收录707个物种，其中本土物种240种、已归化外来物种237种、未归化栽培物种190种、未知物种40种。研究团队为每个鉴定出的物种收集了详细信息，包括植物用途、典型生境、杂草性、具体分布位置以及除本研究团队外的鉴定来源。本数据集将为农业生态学研究提供数据支撑，用于探究植物多样性与周边区域对作物生理及产量的影响。
