Many rare herbaceous plants and insects occur on the island. The west coast of the island supports over 200 plant species. Rare species such as Long’s braya ("Braya longii") and Fernald’s braya ("B. fernaldii"), are endemic to Newfoundland. Brayas are small perennial herbs of the family Brassicaceae. They are only found on a narrow strip of land extending approximately on the extreme western portion of the Great Northern Peninsula, a limestones barrens habitat. The braya population is low due to habitat loss from gravel quarrying. Researchers have only found three populations of Long's braya, and 14 or 15 populations of Fernald's brayas. Researchers have focused on how various types of disturbances affect the long-term viability of these populations. The Province of Newfoundland and Labrador, with many partners, is studying the rare plant flora of the island of Newfoundland and in 2002 announced a recovery plan for the braya species.
