No place, even heavily urban areas can –nor should they– be fully developed or left with barren land.

Even heavily developed islands, such as Manhattan or peninsulas, such as San Francisco possess natural areas (open spaces) characterized by native and introduced vegetation.

Central Park, the Brooklyn Botanical Gardens, or the Bronx Botanical Gardens in New York, or Golden Gate Park in San Franciso are examples of refuges for natural features, surface water and native vegetation to flourish beyond the pavement, structures and buildings of any urban setting.

Urban spaces can of course be enhanced by natural and cultural additions to the features of any place.
