BMZ 1-3:

The purpose of the Biodiversity Management Zone is to provide a refuge for waterfowl (including a high tide roost) and a focus for biodiversity conservation, education and training in a relatively intensively managed environment.

BMZ 4:

Every winter nearly one quarter of the world's population of the endangered Black-faced Spoonbill come to Deep Bay and roost in this part of Mai Po. Management will ensure that these ponds continue to attract Spoonbills.

BMZ 5:

The Mai Po reedbeds are the largest in Hong Kong and amongst the largest in Guangdong Province. This habitat thus needs to be maintained, especially for the rare insects and birds that it supports.

BMZ 6:

Traditional management of the shrimp ponds will be maintained to provide an example of the 'wise use' of wetlands. These ponds produce delicious gei wai shrimps and also support valuable stands of mangrove and their associated wildlife.

BMZ 7:

The long-term intention is to maintain and improve the Education Centre and its associated wildfowl collection.

BMZ 8:

Rainwater will be used to create a series of open freshwater marshes to complement the brackish water ponds elsewhere in the Reserve, and will be managed to attract waterbirds - especially ducks and Little Grebes.

BMZ 9:

An open tidal area with islands will be created to provide a high tide roosting habitat for migratory waterbirds, especially shorebirds that use Deep Bay.

Freshwater marshes

BMZ 10:

A series of freshwater marshes will also be created in this zone, but management will be geared to attracting a greater diversity of wildlife into the Reserve, such as dragonflies.
