Burwell is an area on the edge of the fens, on chalk and clay soils, which is relatively low in ponds, but has several interesting water features.
The castle itself is long since demolished and the moats are no longer filled, alhough they are still boggy. However the moats were spring fed and the springs are still active. They feed a small stream that drains into Burwell lode.
The spring at the moats (hence the 'Spring Close' name) feeds a typical chalk stream quite different from anything else I'm aware of on the fen borders. But the stream soon becomes a fairly typical fen drain which joins Burwell lode.
More information on the site is available from the East Cambridgeshire District County Wildlife Sites Register 2005.
There is also woodland, where Ramsons are now naturalised.
Other aquatic wildlife includes
The two photos show the spring from below and above: it's the same large tree in both. The children are my daughter, Rachel and son Michael. Click on the thumbnails to download a full size picture.
Burwell lode joins the river Cam at Upware, at the back of Wicken Fen. Upware is itself very interesting to aquarists, for here abound Bitterling (Rhodeus sericeus) by the thousand. The books I have on European fish claim that the bitterling is not native to the United Kingdom, and indeed it's listed on eFishBusiness. However, it's certainly been in Burwell lode (as well as in the adjoining Ouse and Cam rivers) for some years now (I first noticed it in the late 1980s) and is doing very well!
For anyone keeping a coldwater aquarium, the bitterling is an ideal fish and has a very interesting biology, using freshwater mussels as host for its young, which makes it symbiotic - as the young of the freshwater mussel are parasitic on fish!
So if anyone in the fish trade wants wild-caught indigenous bitterling, please contact me and I will be glad to supply!
I believe that Zander also are present in the lode.
Amongst plants that may be found, at the Upware end, are:
North of Burwell, on Poor's Fen, there are several pits, market at map refernce 577 690. These are where the clay was dug to make the local bricks, Burwell whites. They are pleasant ponds, but are on private ground so not accessible.
Shown on the map is a lake: this too is a flooded claypit and not easily accessible. It's clear and deep and the remains of a pit railway and other buildings can be seen underwater.
