Climate Change Threatens England's Historic Gardens

Climate change presents a significant threat to over 2,800 historic parks and gardens across England, with green spaces in London, including the Royal Parks, already showing negative impacts.

Recent extreme weather, such as the driest July on record, has led to "flash droughts." These hotter, drier summers stress plants and soils, causing losses of mature trees and shrubs, even in areas not typically prone to drought.

Compounding these issues, outdated drainage systems struggle with intense winter rainfall. Waterlogged soils contribute to erosion and instability, with some sites experiencing flooding for the first time.

In response, site managers are adapting by incorporating more climate-resilient plant species, often sourced from warmer or drier regions. Strategies are being learned from European parks facing similar conditions.

Innovative water management is also being trialled, including the revival of Victorian underground reservoirs to reduce reliance on mains water and reuse captured water across the network.

Furthermore, many conservation plans for these sites are outdated and do not account for climate change, largely due to time and staffing pressures. A more unified approach among heritage organizations is called for to address these urgent challenges.
