  Have you got any old photos of the Foss carefully (or even carelessly) stashed away?   Would you like to share them with the RFS and through us with the wider world? (Not essential – we can just keep them in our archive if you prefer.)   We’ve got three reasons for asking you.   One is for a … Read More

I’m sure you’ve seen and heard quite a bit about otters and mink, recently regarding Covid in farmed mink, but also over many months concerning the effect each of them has on the environment. We have both of these mammals along the Foss from time to time, and have had quite a few reports, as well as photos and videos, … Read More

We’ve got three new videos on the site for you to enjoy, have a look under “The River” 1) Water Monitoring – carrying out the monthly check of water quality 2) Litter picking – a glimpse of the last water-borne pitter pick 3) Slow ‘TV’ – a trip along the Foss from Huntington Road in a kayak.

The RFS has for quite a while been trying to get the waymarking of the Foss Walk improved and the path maintained. Council budgets did not allow for such activities before Covid, thanks mainly to government cuts, so now it’s going to be impossible for the foreseeable future. We’ve been talking to NYCC for a while and the culmination of … Read More

A lot of members collect litter as they walk alongside the Foss, either as a useful adjunct to their walk, or as its main purpose. Without these efforts I can’t imagine what state the riverbanks would be in. Tim went one stage further and used a grapnel to haul out a selection of old bikes and supermarket trolleys – the … Read More

Water Voles. A couple of years ago a group of members together with volunteers from St Nicks waded up most of the Foss from Yearsley baths to Towthorpe and found recent or active water vole traces in several places. We intended to repeat the exercise this summer, particularly as the water levels were very low, but Covid put a stop … Read More

The photos here were taken by Lynne Kinder along Huntington Road recently. It just goes to show that invasive non native species can be pretty – you can see why they are bred for their fur But their voracious appetites and the absence of predators to control them is dangerous It’s no coincidence that we have had no reports of … Read More

Have you seen the terrapin swimming around in the Earswick area? We had quite a few reports and photos from members walking along the banks in the area. One can only assume that someone had it as a pet and disposed of it in the river. It’s apparently quite a common phenomenon and they can survive UK winters and thrive. … Read More

We’re running sessions regularly with teams of no more than six and fully socially distanced. If you’d like to know more let us know via info@riverfosssociety.co.uk . If you’d rather try it en famille or as a small group and would like more information on where to look and how to go about it, ask us your questions. It’s around … Read More

There have been several questions recently about weed in the river. There is a lot of a filamentous alga growing and in some places a surface covering of duckweed is developing. Duckweed, though the individual plants are tiny, is a flowering plant, unlike the alga. Both these are quite normal and tend to occur when flows are low, as now. … Read More
