Houston Arboretum - urban forest remnant within the city

The Houston Arboretum & Nature Center (a roughly 155-acre nature sanctuary) preserves a mature hardwood forest and diverse habitats inside the built environment of the Memorial area, making it an ecological island within metropolitan Houston. Its existence as a contiguous patch of native forest within city limits is notable for biodiversity, environmental education, and as a green refuge amid urban development. The site demonstrates a distinct geographic contrast between natural ecosystems and surrounding urbanization.
