A historic garden conservator is a specialist landscape professional who leads the restoration and management of historically significant parks and gardens. Working from archival research - maps, estate records, planting lists, paintings and early photographs - they develop evidence-based conservation management plans and restoration masterplans. Historic garden conservators are typically involved in National Lottery Heritage Fund bids, planning applications affecting registered parks, and the ongoing stewardship of registered landscapes for private owners, local authorities and the National Trust.
What they do
- Research and assess the history and significance of historic gardens
- Prepare conservation management plans for historic parks and gardens
- Develop restoration masterplans based on archival evidence
- Advise on period-appropriate plant species and sourcing
- Prepare planning statements for development affecting registered parks
- Support National Lottery Heritage Fund applications
- Carry out NPPF setting assessments for registered landscapes
- Manage ongoing conservation programmes for historic gardens

Frequently asked questions
What is a registered historic park or garden?
A registered historic park or garden is a site on the Historic England Register of Parks and Gardens of Special Historic Interest in England - listed at Grade I, II* or II according to national importance. Development affecting registered parks and gardens is a material consideration in planning decisions under the NPPF.
Who manages historic garden conservation projects?
Projects are typically led by a conservation landscape architect (CMLI) or garden historian with IHBC heritage specialism. They coordinate archaeologists, horticulturists, historians and traditional craftspeople as required by the project.
What research informs a historic garden restoration?
Historic maps, estate records, plant catalogues, paintings, photographs and archaeology are all sources. The aim is to understand the garden as it was at its most significant period and to produce an evidence-based restoration that is distinguishable as new work while being true to the historic character.
