 Grey wagtail ("Motacilla cinerea") and kingfisher ("Alcedo atthis") have also been recorded on the reserve.The reserve is managed by both the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire and Bedfordshire Rural Communities Charity through its volunteer group 'Ivel Valley Conservation Volunteers'.Management tasks performed on The Riddy include the coppicing of the small osier bed which stimulates new growth, grazing with cattle to remove each season's growth and to maintain the grassland habitats, along with the removal ('pulling') of ragwort ("Jacobaea vulgaris") which is poisonous to certain animals, notably the grazing cattle, when ingested.
