Conservation Management Plans

Conservation Management Plans are valuable tools in the management of historic parks and gardens.

See the Historic England advice at:

They are evidence-based and take into account the history and current state of the landscape. They set out in detail, actions and strategies for conserving and enhancing the historic fabric and set out a day-to-day management framework. These are typically designed to last for five years with ongoing reviews and critical reviews at the end of the period, leading to a subsequent CMP. The continuity of management practice this gives means that changes in ownership or interim projects can be accommodated without impacting adversely on the landscape.

More details on CMP can be found on The Gardens Trust website at:

Ideally all our 44 sites on the Historic England Register and the majority of our Locally Important sites (see Local Listings) should have such plans and should be kept up-to-date.

They are invaluable weapons for guarding our landscapes as inevitable decay and degradation happen over time and housing and other development pressures increase

Information on the existence and whereabouts of these plans is often difficult to locate but the attached list details those of which HGT is aware. Those where a copy is held by HGT Conservation and Planning are denoted by *, others are held in the Hertfordshire Local Studies and Archives at Hertford. Many of these are out of date and need revising and updating.
