New ponds and management of existing ones are increasing plant species around Pitsford Reservoir.

Conservationists have said the number of uncommon plant species around a reservoir doubled in just two years thanks to a pond creation project.

The Freshwater Habitats Trust (FHT) also revealed wetland plant species across the whole landscape around Pitsford Reservoir in Northamptonshire were up by nearly a quarter.

A total of 22 new clean water ponds have been created and 10 existing ponds have been managed.
