Cambium Sustainable delivers high quality Forest School Training, Curriculum Based Outdoor Learning Training, Coastal School Training and more; empowering people to enrich their lives through engaging with their local natural environment.

We facilitate the UK’s most connected and progressive network of Forest School and Outdoor Learning Training Providers. Our vision is for a professional community of practice that is empowered to create meaningful change, both in the learners they work with and ultimately in the wider communities they serve.

We believe that we are all part of nature. Everyone needs access to natural spaces for play and learning, this is a fundamental right. The natural world needs eco-literate young people with an emotional connection to and respect for nature. Quality training, resources, networking, and support are key to manifesting this future.

We will achieve this by:

  • Developing efficient, streamlined systems that are clear, secure, easy to use and understood by all.

  • Empowering all staff and associates to do their best work in a way that suits their individual situation and character.

  • Maintaining open communication and a responsive approach, putting people and the natural world at the centre of all we do.

  • Listening to feedback and being open to change.

  • Dealing with people as individuals, not statistics.

  • Focusing on quality training and delivery and striving for a culture of constant improvement and development.

  • Growing the Cambium Trainers Network in a sustainable way, ensuring that staff and systems are in place to support any expansion.
