Sue Finn - Secretary

Sue has been interested in all aspects of the natural world since childhood. She spent her 38 year career teaching in primary, secondary, and special needs settings, developing children’s curiosity in their natural surroundings. This did not always go smoothly. Rescuing escaped snails from a classroom ceiling was an interesting challenge!  In 1989, Sue moved to work with the Educational Psychology Service which included running In-Service training for teachers. During the latter part of her career, she worked in nurseries and reception classes, researching the problems of poor language skills and implementing language enrichment programmes.

Since retiring, Sue has travelled around the world with husband, Roger. She remains an enthusiastic bird watcher and monitors a bird box round on the Wyeswood reserve. Sue also enjoys baking and provides cake for Trust committee meetings.

Juliet Holt-Wilson

Juliet has a background in advertising and marketing as well as the Third Sector. She began her career working within creative agencies developing TV, print and radio strategy and campaigns for brands such as McCain and Wall’s, Three Mobile and The Discovery Channel, and has worked in-house with website development, social media content, PR and influencers. She topped and tailed her commercial work with stints at the British Academy of Film and Television Arts and Comic Relief’s volunteering spin off, TimeBank. 

Moving to South Wales with her growing family, Juliet took on the family farm. As an organic farmer, she rears native-breed cattle within a wholly outdoor and grass-fed rotational grazing system. The farm encompasses woodland and wetland habitats, as well as traditionally managed haymeadows and unimproved pasture. A walk around their family farm often demands admiring dung beetles in poo piles, wildflowers and grasses as well as, probably her greatest love of all, fungi. Working with and within nature is a source of continual learning for her as well as demanding adaptability and embracing tacit, observational knowledge.
