In addition, functionally healthy and established natural communities are better able to resist invasions by alien plant species. So the use of native plants can help prevent the spread of alien species already present in a region and help avert future introductions. With the large variety of grasses, ferns, wildflowers, shrubs and trees from which to choose, native plants can fulfill any landscaping need, from simple container gardens to showy perennial borders to expansive public lawns and gardens. Native plants provide familiar sources of food and shelter for wildlife. As natural habitats are replaced by urban and suburban development, the use of native plants in landscaping can provide essential shelter for displaced wildlife.
Land managers can use native plants to maintain and restore wildlife habitat.
Native wildlife species comprise a majority of the game and non-game animals we manage habitat for, and they evolved with native plant species. Although alien species are often promoted for their value as wildlife food plants, there is no evidence that alien plant materials are superior to native plants. Dramatic increases in nesting success of both game birds and songbirds have been observed in fields planted with native grasses, which also offer superior winter cover. In addition, warm season grasses provide productive and palatable livestock forage. On a broader ecological scale, planting native species contributes to the overall health of natural communities.
