[1][5] Typically, urban wilds are home to native vegetation and animal life as well as some introduced species.
Land tenure of a single ecological area can be complex, with multiple public and private entities owning adjacent properties.
[10][11] Key strategies used in the preservation of urban wilds have included conservation restrictions that keep complex land tenure systems in place while protecting the entire landscape.
[10] The urban wilds prioritized by municipalities tend to be partial wetlands that perform a range of ecological services while contributing to the biological diversity of the region.
[12] There is some discussion about whether natural areas that are not at an appropriate scale to perform significant ecosystem services should instead be categorized as passive parks as opposed to urban wilds.
