| Another butterfly visitor is the crowberry blue, which frequents coastal bogs and while in its larval stage eats black crowberry. |
| Some areas colonized by the aster and crowberry have already been disturbed, particularly on the east side of East Pond. |
| Wiry ankle-high shrubs are interspersed with mounds of diapensia and mats of creeping crowberry, bearberry, moss and lichens. |
| They seemed to be feeding to some extent on the patches of crowberry and dwarf birch. |
| Many of the shrubs are berry plants, such as low bilberry, mountain cranberry, bearberry, and crowberry, and bears graze on these in late summer. |
| However, the leaves of the mountain heath have finely toothed margins, whereas those of the crowberry are smooth. |
