1. Explain what a natural, constructed and managed environment is.

managed environment

In Design and Technologies, an environment coordinated by humans, for example, a farm, forest, marine park, waterway, wetland and storage facility.

Natural environment

The Natural and Built Environment. Background: As cities grow, the natural environment becomes transformed, from the native vegeta- tion into a diverse assemblage of built materials, including buildings, parking lots and roadways. This has impacts on all organisms, native and non-native, including humans.

Constructed environments

This dataset includes a variety of constructed features, (e.g, fences, bridges, culverts, buildings, communication systems, gates, etc.) and non-constructed features which may include natural barriers and other features that need to be maintained spatially.
