Project Officer: Tim Longstaff 

Tim joined the Trust in September 2018. He has a lifelong interest in rivers and is an occasional fisherman.  Prior to joining RTCT he worked for over seven years at the South East Rivers Trust as a senior project officer. He brings with him a wealth of experience in managing both large and small fish passage and habitat improvement projects through from idea to delivery.  He was instrumental in the award-winning restoration of the Carshalton arm of the River Wandle in South London that culminated in the successful recruitment of trout in the river for the first time in 80 years.  The river also became the first urban heavily modified water body in the UK to reach ‘good ecological potential’ (GEP) for the purposes of the EU’s Water Framework Directive.

Project Officer: Hannah Worker

Hannah joined the Trust in April 2018. She has a background in biology and freshwater ecology from undertaking a Biology degree from Sussex University. She joins us from Freshwater Habitats Trust where she worked as a project assistant on their national People, Ponds and Water project. Through this she was able to expand and explore her love of freshwater creatures and plants, and was able to visit some of the most stunning ponds and freshwater landscapes in the country. One of her favourite creatures is medicinal leech and a much loved plant is Pillwort, a small aquatic fern.

She hopes to use her skills to help set up recording networks for freshwater plants and animals across the catchment, as well as getting stuck into practical habitat creation projects and to raise awareness of the River Thame’s amazing freshwater wildlife.
