Find out More
Matt started his current role as Fishery Habitat Officer in October 2021 after being with the trust since 2017, initially joining in a community engagement role. His role involves looking at how fish passage can be improved within the catchment, taking on fish passage projects – be it technical fish pass or weir removal, as well as ensuring maintenance of our fish passes and that of other stakeholders. This includes looking at where in the catchment habitat improvements can be made to help fish populations thrive, by installing large woody debris. Monitoring is an important aspect of fishery work and Matt will soon be embarking on electrofishing surveys to search the catchment for salmon fry/parr, helping to establish how successful fish passage schemes have been and whether the habitat requirements are adequate. Matt also runs community engagement activities, allowing people to volunteer and learn more about the Don’s fishery.
In previous roles Matt enjoyed going out regularly with volunteer groups which he helped establish in Chesterfield as part of the Hidden Heritage Secret Streams project, and loved working in the beautiful Moss Valley on Natural Flood Management and habitat improvements. A particular proud point for Matt is the delivering of Mayfly in the Classroom sessions to primary schools in Rotherham and Doncaster.
After leaving the University of Leeds with a bachelor of science, Matt started his career on placement at the Sheffield and Rotherham Wildlife Trust within their reserves team. After which he worked at the River Stewardship Company for five years delivering flood risk, habitat improvement and community engagement activities.

Our Trustees
David Rowley
Chair Of Trustees
Find out More
David became involved in the Rivers Trust movement through his passion for fly fishing. It was through fishing that he first became interested in fly tying and invertebrates. He fairly quickly realised that without protected rivers there may not be a future for invertebrates, fish or fishing.
He attended one of the early meetings of the group who were trying to form a rivers trust for the Don catchment and stayed. He was one of the three founding trustees of DCRT.
After working in the banking and IT industry when he retired he devotes time to DCRT, fly fishing and invertebrate monitoring. He is a keen watercolour painter and dog walker. David is the chairman of the South Yorkshire branch of Salmon & Trout Association and an executive vice president of WildFish, the new name for the S&TA national.
Chris Firth MBE
Trustee
Find out More
On his retirement in 2004 Chris helped form the Don Catchment Rivers Trust and became a Director and Trustee when the Trust received its charitable status in 2010. His experience and knowledge means that he can provide invaluable contributions to many aspects of the Trust’s work, personal highlights of this have been the Living Heritage of the River Don and Hidden Heritage Secret Streams.
Chris was born in Doncaster close to the banks of the River Don and early in life developed a passionate interest in the river. Although he began his working career in engineering, in 1975 he took up a post as a Fisheries Bailiff working in the West Cumbria area of the Lake District. In 1977 he moved to Beverley where he began work with the Yorkshire Water Authority as a Fisheries Inspector. Here his responsibilities included all aspects of fishery management including the management of the licenced salmon net fishery along the Yorkshire coast.
In 1983 he was promoted to Fisheries Officer based at Doncaster and began work on the rehabilitation of the River Don and its fishery. This included one of the first ever re-meandering schemes of an industrial river (the River Dearne) and the hugely innovative Crimpsall Rock Ramp fish pass on the River Don. In 1999, following dramatic improvements in the environment and ecology of the Don system, the Environment Agency published his book ‘Doomsday to the Dawn of the New Millennium’ an account of the demise and recovery of the fish populations of the river. In 2000 he was awarded an MBE for services to the Environment and Community.
Chris is a lifelong fitness fanatic and played for the Doncaster’s premier rugby league side ‘The Dons’ and was an active member of Doncaster Athletics Club. An avid angler, he can be found on the riverbank or spending time with family.
Peter Worrall
Trustee

As a consultant hydro-ecologist and Director of Penny Anderson Associates Ltd (Consultant Ecologists) Peter has worked with rivers and wetlands in many parts of the UK as well as other countries including Portugal, Italy and Saudi Arabia. He was involved in the diversion of the Twin Rivers around Heathrow Airport’s Terminal 5, and the ecological enhancement of the River Bollin as it passes beneath Manchester Airport’s second runway. In recent years he produced The Mersey Life Portfolio for the Environment Agency which is a compilation of schemes for ecological improvements to the River Mersey and its catchment.
Educated at Sheffield and Manchester Universities, Peter has always had an interest in the River Don. In the 1980’s, as a documentary radio programme maker for the BBC he produced a series about fishing in which one episode dealt with the early attempts at restoring a game fishery to the Upper Don; later he spent much time volunteering in the restoration of Wortley Top Forge, following another of his interests in industrial archaeology.
Wherever there is water there is wildlife and Peter has become an expert ornithologist with a particular specialism in the behavioural ecology of wetland birds. This passion has led Peter to be involved in the creation of ponds, lakes, marshes and reedbeds in both rural and urban areas. Peter believes that by restoring our rivers, together with their associated floodplains and catchments an opportunity exists to establish approaches to natural flood management which would have multiple benefits for people, wildlife and flood risk.
Now partially retired Peter hopes to be able to use some of his time to support the work of the Trust.
