Derek Pretswell is a zoology graduate of Aberdeen and started working on forestry and landuse with Ron in 1982/3 while both of them were fishery biologists with the Department of Agriculture for Scotland. A founder member of the Loch Garry Tree Group and Perth Bat Group, he served on the management committee of the Scottish Wildlife Trust reserve at Loch of the Lowes and was a Trustee of Scottish Native Woods for 10 years. In addition, he was a member of the Cairngorm Community Circle and a member of the SNP environmental policy group which, along with Ron and under Roger Mullin’s leadership, formulated the SNP’s main policy document.
Together with Ron, Derek founded Natural Resources Scotland in 1992 and developed the New Caledonia Project which is a holistic long term project that encapsulates the three tenets of sustainable development to bring about the ‘blossoming’ of our biological, social and economic landscape. Derek now teaches environmental education to schoolchildren from North Lanarkshire at an outdoor centre in Oban and during the summer takes to the lochs with Ron to research Arctic Charr populations.
