Invasive plant observations

Invasive plant observation locations were extracted from three databases: (1) iNaturalist research-grade observations (GBIF 2019), (2) EDDMapS (University of Georgia Center for Invasive Species and Ecosystem Health 2019), and (3) iMapInvasives (NatureServe 2019). Each entry was updated with the currently-accepted and previously-accepted scientific names based from ITIS (2019). Previously-accepted scientific names were retained in the case that an invasive plant record was collected using that name. All common names were also retained. We selected only observations made prior to 2012 from states of CT, MA, ME, NH, NJ, NY, PA, RI, VT.入侵植物观测点位从三类数据库中提取得到：(1) iNaturalist平台研究级观测记录（全球生物多样性信息机构（Global Biodiversity Information Facility, GBIF），2019年）；(2) EDDMapS数据库（佐治亚大学入侵物种与生态系统健康中心，2019年）；(3) iMapInvasives数据库（NatureServe机构，2019年）。每条记录均依据综合分类学信息系统（Integrated Taxonomic Information System, ITIS）2019年版更新为当前公认学名与曾用学名；若入侵植物记录采用曾用学名采集，则保留该曾用学名。所有通用名亦予以留存。本次研究仅选取2012年之前，于康涅狄格州（CT）、马萨诸塞州（MA）、缅因州（ME）、新罕布什尔州（NH）、新泽西州（NJ）、纽约州（NY）、宾夕法尼亚州（PA）、罗得岛州（RI）及佛蒙特州（VT）开展的观测记录。
