Keystone Plants:Plants that have maximum ecological value
Keystone plants are native species that provide the maximum ecological value within an ecosystem, supporting more wildlife than almost any other plants. They serve as the foundation of local food webs by hosting abundant insects, providing food and shelter for birds, mammals, and pollinators. Examples include oaks (Quercus), willows (Salix), cherries (Prunus), birches (Betula), as well as native perennials like goldenrods (Solidago).
Because so many caterpillars and other insects depend on these plants, keystone species indirectly sustain a wide variety of wildlife year-round.
Planting keystone species is one of the most effective ways to restore and enhance wildlife habitat. Even in small yards or fragmented landscapes, these plants produce far more ecological benefits than ornamental or non-native species. By supporting insects, they feed birds, small mammals, and predators, creating self-sustaining ecosystems. Whether restoring a woodland, meadow, or backyard garden, keystone plants help rebuild resilient habitats that ensure wildlife thrives for generations to come.
