These impacts, driven by climate change – which is mostly caused by burning fossil fuels for power plants, cars, heating and industry – are affecting all aspects of these heritage landscapes, from trees and plant collections to paths, terraces and lakes. And while all sites are responding in practical ways where they can, for example prioritising actions that will help adapt to climate change, they warn they are spending more time on emergency responses and maintenance. The report stated: "A major finding is that strategic planning undertaken by parks and gardens is not keeping pace with climate change pressures. "Although about three quarters of interviewees say their sites have conservation plans, many of these plans are outdated and do not consider climate change in practical terms. He added: "It’s clear our historic parks, gardens and cemeteries are facing unprecedented challenges due to climate change, and without urgent guidance and advice, many of these precious landscapes will suffer and change beyond recognition.
