GRIPP Yukon Draba

Endemic plants are defined as species whose habitat is restricted to one location in the entire world. It is estimated that Canada is home to 93 endemic vascular plants. Of these species, many are found in Northern parts of Canada (i.e. Yukon, Northwest Territories, and Nunavut) and suggests that Tundra, Taiga, and boreal regions of Canada are hotspots for endemism. Unfortunately, these habitats are also under significant pressure due to global warming. GRIPP is committed to helping protect species which are either endemic to Canada or a specific eco-region in Canada through development of in vitro technologies.

Yukon Draba is endemic to Canada, being found only in one meadow complex in southwestern Yukon.

GRIPP Yukon Draba
  • Yukon draba has an extant of occurrence of 1.01 Km2 (smallest imaginary border drawn around all presently known, inferred, or project sites of occurrence)
  • This species is believed to be a relict species (likely once widespread in the past) being associated with ancient beaches and spits.
  • Populations can fluctuate significantly ranging from 32,500-88,200 individuals in high population years, to as low as 1,500-2,100 individuals during a low population year.

Hairy Braya is endemic to the Northwest Territories with 13 populations being located on the northern portion of Cape Bathurst and nearby Baillie Islands.

GRIPP Braya pilosa
  • Hairy Braya was first reported in 1826 during expedition Sir John Franklin͛’s with further collections taking place in 1848 and 1850.
  • Recent estimates suggest that 12,000-16,000 mature individuals are still in the wild.It is believed.
  • that this species played may have played an evolutionary role for other Braya species.
