Parks / Nunavut
In the gravel-like outwash of the glaciers,
little vegetation exists aside from the lichens
on the glacial moraines and the cushion plants
such as campion, saxifrage and mountain avens
sheltered at their base. Tundra species grow
on wind-blown sand that can support dwarf shrubs
- birch, willow, heather and blueberry - and
tufts of grasses called thufor.
On the edges of fjords and the coastline of
the Davis Strait, some tidal flat plants have
developed. The sparse vegetation growth and
its limited diversity result from thin, nutrient-poor
soils, harsh winters and short summers. Many
arctic plants grow in clumps, creating their
own warmer micro-climate, and in tussocks built
up by their own root systems over many summers.
Cotton grass sedge grows in boggy areas and
the pink and purple Broad-leafed Willow herb
and yellow arctic poppy survive in quite barren
areas. In all, 112 species of vascular plants,
129 bryophytes and 97 lichens have been catalogued
in the park.
