Wild Nuts in Canada
Nuts are the hard-shelled fruits of flowering trees or shrubs. Within each shell are one or more seed kernels that are easily separated from the outer shell. Most nuts are edible and nutritious, and are sought after by many animals as well as people. There are about 20 edible nut species native to Canada. Most of these species are found in the Great Lakes-St Lawrence and deciduous forest regions of southeastern Canada, including the American hazelnut (Corylus americana), American beechnut (Fagus grandifolia) and black walnut (Juglans nigra). Nuts found in western Canada include the beaked hazelnut (Corylus cornuta), whitebark pine seeds (Pinus albicaulis), and garry oak acorns (Quercus garryana). Virtually all are known to have been used as food by Indigenous Peoples. Some are still harvested and used today, but most have been replaced in peoples’ diets by imported nut species such as European filbert (Corylus avellana), English or Persian walnut (Juglans regia), American pecan (Carya illinoinensis) and cashews (Anacardium occidentale).
