Yukon Conservation Data Centre Vascular plant watch list Updated February 2019 This is a list of vascular plants for which more information is needed before a conservation status can be determined, but which may be threatened or endangered in Yukon or throughout their range. The Yukon Conservation Data Centre is not mapping these species in our database at this time, but is actively seeking reports on known populations so that in future we may be able to make an informed assessment of their conservation status. Some species on this list may be eventually placed on the Track List, while others will be removed from the list as more populations are reported. We encourage all to report sightings of these species to us but do not require detailed information. A simple location and date with your contact information will suffice. Documentation, such as a specimen or a photograph, is required to confirm identification.
