Until very recently, there were too few women in conservation or the natural sciences. Steph Tyler was one of the few, a pioneer. Her professional career took her from Gwent Wildlife Trust to the RSPB as Wales Conservation Officer, but she has been involved with the Gwent birding scene continuously since 1981. With Professor Steve Ormerod, she authored the standard volume on Dippers, and wrote numerous papers that highlighted the impact of acid rain and forestry on water quality, insects and Dippers in the Welsh uplands. That was a huge environmental issue in the 1970s and ‘80s, and Steph was central to gathering the evidence that brought about change for the better.
