| As elevation increases, trees become stunted and above the treeline only shrubs, moss, lichen and herbs are found. |
| Forestry activities within habitats tend to promote homogeneity and result in a depauperate lichen community. |
| In 1980, an old ash tree in Cumbria on which this lichen grew, had to be felled for safety reasons. |
| The outside of the nest is camouflaged with moss, bud scales, leaves, and lichen, and often looks like a bump or knot on the branch. |
| Because of their sedentary character and free grazing habit, reindeer tend to trample and overgraze lichen pastures during summer and autumn. |
| On our moss-covered trails, mats of shrubby gray reindeer lichen and Iceland lichen are common. |
