Ingrebourne Marshes, Nature reserve and Site of Special Scientific Interest in Hornchurch, London Borough of Havering, Great Britain.
Ingrebourne Marshes is a nature reserve running along both sides of the River Ingrebourne, featuring wetlands, woodland, grassland, and riverbank habitats. The site contains a mix of these different environments that support a wide range of wildlife.
The reserve sits adjacent to the former RAF Hornchurch airbase, which served as a vital airfield for Spitfire fighters during World War Two. Military structures from that period remain visible throughout the area.
The Nature Discovery Centre offers guided walks and workshops where locals and visitors learn about the plants and animals living here. These activities help people develop a closer connection to the natural world on their doorstep.
You can reach the public sections through Hornchurch Country Park and Berwick Pond Road, with parking located at the northern end on Hacton Lane. Walking and cycling are good ways to explore the site, though paths are easier to navigate in drier weather.
The site hosts over 60 breeding bird species and rare invertebrates such as the hoverfly Anasimyia interpuncta and scarce emerald damselfly. This variety of life makes it particularly rewarding for birdwatchers and nature enthusiasts.
