They practiced controlled burning of patches, which promoted the growth of a variety of berries including Vaccinium (bog blueberries) and salal berries.
Elizabeth Coleman White (October 5, 1871 – November 11, 1954) was a New Jersey agricultural specialist who collaborated with Frank Coville to develop and commercialize a cultivated blueberry.
The foodplants of this genus are not too well known, but appear to be limited by availability rather than being restricted to a particular lineage of plants; recorded are for example Bidens (beggarticks) and Vaccinium (blueberries and relatives), which are both asterids but otherwise unrelated.
The three varieties are solid chocolate; chocolate with macadamia nuts and dried cranberries; and chocolate with cranberries, blueberries, pomegranate, and almonds.
Heath plants common to this ecology include mountain-laurel, Kalmia latifolia, various blueberries, genus Vaccinium, huckleberries, genus Gaylussacia, sourwood (or sorrel-tree), Oxydendron arboreum, and azaleas and rhododendrons, genus Rhododendron.
In Alaska, snowshoe hares consume new leaves of blueberries (Vaccinium spp.), new shoots of field horsetails (Equisetum arvense), and fireweed (Epilobium angustifolium) in spring.
