Mastering the river environment

Rosie Nelson – Masters Student

I’m Rosie and I’m two months in to my research masters at Durham University, kindly sponsored through the North York Moors National Park Authority with funding from Biffa Award. Since my second year of university, I’ve known I wanted to work with (or in) rivers, and this masters should help me get one step closer to achieving that.

I’m investigating the water quality of three hotspot tributaries of the Esk: Danby Beck, Toad Beck and Great Fryup Beck, in the hope to identify point source pollution and its cause/s. Ensuring good water quality is crucial for the health of the river and paramount for the Freshwater pearl mussels that live there. The key contaminants I will be looking at are Phosphate, Nitrogen and Ammonium. The Esk currently exceeds the thresholds for these three elements/compounds which pollute the river environment and damage freshwater systems. I hope that through my data collection and analysis I can identify point source pollution issues and help reduce the contaminants entering the Esk. Hopefully making the Freshwater pearl mussels a little bit happier!

Being based in the Authority’s Conservation Department for at least one day a week is proving to be very helpful. Not only am I extremely productive, but I’m also learning what it’s like to work in a conservation environment – something I definitely hope to be doing in the future.

At the start of May, I got to join in with the Salmon in the Classroom project alongside Simon the River Esk Project Officer and Alex the Catchment Partnership Officer. Simon taught me how to kick sample, something I really wish I’d known how to do before. You get into a safe watercourse with a fishing net, place the net downstream of you and kick the river bed. After several kicks, you empty the net into a bucket of water and hope you’ve found things, like invertebrates and potentially even fish! After several kick samples, we had collected enough living invertebrates for the children and me to identify.

Last week I went out with Alex in Glaisdale in the Esk Catchment, and aside from us both getting stuck in the mud I had a great day (luckily I was holding a spade and could dig us out!). In the morning we visited a farm which is perfect for bank stabilisation work to lessen the amount of sedimentation. In the afternoon at a different site in the dale we planted trees and sowed grass seed to re-vegetate where a new drinking bay had been installed (to provide water for stock which are now fenced off from the river).

Well that’s just a snippet of the things I’ve been getting up to in the past couple of months, not forgetting reading as much as physically possible about anything and everything river related!
