Guided walks and wildlife surveys saw people of all ages getting closer to nature.
The Wildlife and Wetlands Trust (WWT) in Welney was a hive of activity on Sunday to celebrate World Wetlands Day.
An open day was held which included everything from small mammal surveys to bird ringing demonstrations.
Wildlife lovers and families were also able to enjoy commentated wild swan feeds, owl pellet dissections, guided walks and informative talks.
Sam Lee, the reserve’s public engagement officer, said: “Our World Wetlands Day open day was a great success.
“Wetlands are one of the most biodiverse habitats on earth. They are home to more wildlife and plant species than any other habitat, yet few people realise just how important they are even for us humans.
“Wetlands provide ecosystem services which we rely on and take for granted such as filtering water, flood protection, food, raw materials and carbon storage.
“Visitors were not only able to get closer to nature with the activities we put on but they were also able to enjoy the sense of wellbeing that connecting with wildlife and being outside in a beautiful landscape can offer.”
Floodlit swan feeds are held at the reserve every Thursday to Sunday throughout February at 6.30pm.
