About the reserve

A small but perfectly formed pocket of wildness, Milton Locks nature reserve is a coastal oasis on the border of Portsmouth’s urban sprawl. It’s the last natural section of coastline on this on this side of Langstone Harbour and is packed full of different habitats and wildlife.

The small wood provides much needed shelter to birds such as starlings and house sparrows, and the nectar-rich flowers that grow in the dappled sunlight provide food for painted lady and small copper butterflies. The path snakes through tall grass, which buzzes with an orchestra of grasshoppers and crickets, before opening out to the shoreline. 

Depending on the tide, you might be lucky enough to spot tiny fish in the shallows, crabs scuttling between clumps of seaweed, or oystercatchers foraging on the mudflats. And don’t forget to look out saltmarsh specialist plants, like sea purslane, sea aster and common saltmarsh-grass.
