 Lichens cover the bare, wave-washed rocks while the herbs are restricted to cracks and crevices in the rocks where soil has been able to accumulate.Many of these plants such as the butterwort, the three toothed cinquefoil, crowberry and bird’s eye primrose are not found elsewhere in the park and are part of a vegetation association known as an Arctic disjunct community, that is, the discrete association isolated from its main geographical location.Source
