Is Setting aside a marsh as a wildlife refuge is an example of what approach to protecting biodiversity?

Setting aside a marsh as a wildlife refuge is an example of a conservation approach known as habitat preservation or protected area designation. This strategy aims to safeguard specific ecosystems and the species that inhabit them by limiting human activity and development in those areas. By creating designated refuges, biodiversity is maintained, and ecological processes are preserved, helping to sustain both wildlife populations and their habitats.
