Abstract
This document includes taxonomically-organized lists of all vascular plants, amphibians and reptiles, birds, and mammals recorded from the 350 ha Koffler Scientific Reserve of the University of Toronto, in King Township, Regional Municipality of York, Ontario, Canada (44° 01' N, 79° 31' W). These lists were initially compiled by C.S. Blaney and were published as an appendix to his M.Sc. thesis (Blaney C.S. 1999), conducted under the supervision of P.M. Kotanen. They subsequently were formatted for the web by P.M. Kotanen and made available on the Koffler Scientific Reserve website (http://ksr.utoronto.ca/), where they were revised periodically to reflect additions and taxonomic changes. A major revision in 2020, led by T. Babar, reflected recent phylogenetic and nomenclatural changes and added additional species. These revised lists included numerous additional observations of birds contributed by T. McKenzie and G. Reed. Additional information on each list is provided in that particular section.
These lists are current as of 21 June 2024. Additional species (e.g., Passenger Pigeon, Black Bear) undoubtably occurred at this site prior to European settlement, but are not documented in the existing record. Information on any additional species (preferably with photographs or specimens) should be directed to the correspondence author. These lists document the existing biodiversity of this rapidly urbanizing area. Both current users and future researchers should benefit from the permanent availability of this unique resource.
