- Neglect is one of the most common risks. It might show up as litter, overgrown paths, damaged signage, or deteriorating planting schemes. Even when loved by the community, signs of neglect can make a place feel forgotten and reduce public enjoyment.
- Vandalism, including graffiti, damaged features, or trampled planting beds, not only causes physical harm but can have emotional and financial impacts—restoring historical elements is costly and often difficult.
- Development pressure is another threat. New roads, housing, or commercial buildings near or within historic landscapes can disrupt views, layouts, and ecological balance. However, historic parks and gardens can help to support appropriate, good quality development by providing accessible green space for local residents and vital refuges for nature. Development can therefore also be a positive opportunity.
- Climate change is having growing effects—more frequent flooding, droughts, or storms can damage planting schemes and threaten long-established trees.
- Poor maintenance funding often leads to reduced staff, equipment, and planning, making it harder to care for these complex spaces.
- Invasive species and pests also pose a significant challenge, affecting plant health and biodiversity.
