Surprising discovery along the Little Ouse

We have been putting out wildlife cameras for many years along the headwaters of the Little Ouse, especially as part of our Otter and Water Vole studies (Langston, R. & Rivett, A. 2020; Langston, R. et al. 2022), and have collected some lovely video and audio clips of many different species. These clips include Otters feeding, social interactions between Otters, a Fox reluctantly getting its feet wet, wintering Chiffchaff flycatching, Kingfisher “beating” its Bullhead prey prior to swallowing it, and many more insights to the comings and goings of local wildlife.

Imagine our surprise when a recent clip recorded a mammal we had not seen before along the river: a BEAVER! We have no idea where this Beaver has come from. It is possibly an escapee from one of the licensed releases into “secure” enclosures, or it might be an illegal release. We are investigating possible origins.

Either way, it has stayed around for a while now, and we are starting to find feeding signs. Our camera footage includes it feeding on Willow twigs. We first recorded it on camera on 2nd November. Beavers have been extinct in Britain for several hundred years and Otters around now, are likely to have had little or no prior experience of Beavers. We will continue to monitor activity and signs, along with our other mammal recording. Beavers are mainly crepuscular (active at dawn and dusk) or nocturnal, so you are more likely to see signs than the Beaver. Please respect the wildlife that shares the valley with us and don’t try to search for it, which is likely to cause disturbance.

LOHP's Newest Reserve

With the purchase of Prince Freddy’s Meadows, 27 acres (11ha) of pasture and woodland beside the infant Little Ouse at Blo’ Norton, the Little Ouse Headwaters Project has taken on by far its most ambitious project yet. The meadows are named after Prince Frederick Duleep Singh, who lived at nearby Blo’ Norton Hall from 1909 to 1926. This fascinating piece of land would also have been familiar to Virginia Woolf, who stayed at Blo’ Norton Hall in 1906, and who wrote affectionately of the area and even swam in the river.

Over the years the land, and the flow of the river, has been much altered, so the LOHP faces the formidable challenge of restoring it to its former glory. It has interesting wildlife, with otters and water voles, breeding mandarin ducks and visiting red deer, but has the potential to be much richer.

Ellie Beach, LOHP’s Conservation Manager, warns that “It will require a year of intensive study of the topography and existing flora and fauna before any work on the land is undertaken. Our aim is to eventually restore the old meandering course of the Little Ouse and to bring back the rich biodiversity that the meadows must have once had.”

Chair of Trustees, Rob Robinson, commented "LOHP was started by volunteers 23 years ago with the aim of improving the habitat along the headwaters of the Little Ouse, which is nationally very rare. This land is a vital piece in the jigsaw and its restoration, although daunting, has the potential to become a real haven for wildlife."

There is currently no public access to Prince Freddy’s Meadows, but LOHP plans to provide access points where there are good views of the river as part of its plans to restore the site. Join us at our AGM on Friday 5th December to hear more about Prince Freddy's Meadows, or come along and visit on Sunday 11th January 2026 - See Events page for more details or visit Prince Freddy's Meadows webpage.

Donations to help restore Prince Freddy's Meadows can be made to LOHP at JustGiving.

Volunteers Week

As part of Volunteers Week (3nd to 8th June) we hold our annual Volunteer Away Day where we invite our volunteers to have a day off from undertaking volunteering for us and visit other organisations and see what they are doing.

This year we visited Chippenham Fen National Nature Reserve (NNR), in Cambridgeshire. The site is managed by Natural England (NE). Senior Reserves Manager for NE, Chris Hainsworth met us and gave us a guided walk around the reserve.

We were told all about the history and management of the reserve. Which included their recent project to try and improve the peat soils across the reserve by increasing their wetness. This was done by installing a series of dams.

We also were lucky enough to encounter some of the rarer species found on the site such as Cambridgeshire Milk Parsley, Silver Barred Moths and Beruladium procurens a hybrid umbellifer. There were also lots of more common things including Orchids, Sedges, Bog Bean, Bog Pimpernel, along with a Grasshopper Warbler and Marsh Harrier.

Everyone found the morning really enjoyable and informative, a nice change from doing practical work, hopefully everyone will be spurred on to get back to work next week.
