Conservation. Although there has has been a decline in extent and loss of important local sites in Barnsley, there are still opportunities to protect and conserve this habitat.
Factors causing loss or decline
Open Mosaic Habitat on Previously Developed Land (OMH) does not necessarily have legal protection .
OMH is however listed under Section 41 of the NERC Act as a habitat of prinicipal importance for conservation. As a result public bodies have to take it into consideration when managing their estate and making decisions.
An OMH site may be designated as a Site of Special Scientific Interest, Local Nature Reserve, Local Wildlife Site or another local or national designation.
It is also important to note that an OMH site may also be indirectly protected where it provides a habitat for a legally protected species under the Wildlife and Countryside Act 1981 (the Act), or the Conservation of Habitats and Species Regulations 2010.

Positive Conservation Management
Although an absence of management is often a key factor in the high biodiversity in brownfield sites, management will be necessary at some point to maintain the early successional habitats required.
Without management sites will in time be overgrown by dense scrub and secondary woodland. The aim should be to maintain open, sheltered and sunny areas, with a mosaic of herb-rich early succession habitat and bare ground. This involves:
