Leaves are retained year-around, which enables the plant to photosynthesize even when the temperature drops sharply. With little sun, water evaporates slowly, making more available for plants or animals to use.

Bearberry plants can reach between six and eight inches in height. Tundra organisms are opportunistic. The larger and taller they grow, the more they can influence soil temperatures and thaw the permafrost layer, or even change the soils nutrient cycle and carbon levels (affecting decomposition and the amount of CO2 released into the atmosphere).
