The list of vascular plants for the city of Toronto

Urban areas have become epicenters for applied ecological and conservation research and policy. Yet, most urban areas have surprisingly little consolidated information about their biota, including species-at-risk and invasive species. I used multiple data sources to compile a list of vascular plants for the greater metropolitan Toronto region. This data not only includes taxonomic information, but also global and national status ranks, growth from, native status, threatened status, abundance estimates and year of first observation for non-indigenous species. The list includes 1937 taxa from 146 families, of which 822 are non-indigenous. The majority of native species were ranked as abundant and widespread both globally and provincially. However, non-indigenous species ranks were bimodal, likely to be either extremely restricted in the province, or very widespread. This database provides a robust list of plant taxa in Canada’s largest city. It will inform global urban ecology an...城市区域已成为应用生态学、保护研究与政策制定的核心枢纽。然而，绝大多数城市区域的生物类群整合信息仍极为匮乏，涉及濒危物种（species-at-risk）与入侵物种。 本研究通过多源数据汇编了大多伦多都会区的维管植物（vascular plants）名录。该名录不仅包含分类学信息，还涵盖全球与国家级状态等级、生长型、本土性状态、受威胁等级、丰度估算，以及外来物种（non-indigenous species）的首次观测年份。 该名录共计收录146科1937个分类单元（taxa），其中外来物种822个。多数本土物种在全球及省内均被评定为丰富且广布；然而外来物种的等级分布呈现双峰模式，要么在省内极度受限，要么分布极广。 本数据库为加拿大最大城市的植物分类单元提供了一份可靠名录，将为全球城市生态学及……
