Our Story

Our Vision

To enable people to become “agents of connectedness” in their inner and outer worlds, together creating a global network of care.

Our Mission

To provide widespread access to a global online community with local in-person hubs, based around nature’s principles, to foster positivity and emotional resilience for the future.

Our Roots

Qualitative research after a psilocybin trial showed that participants felt more connected to self, others and world (particularly nature). However, that feeling of connectedness diminished after a few weeks or months. Our founder, Dr Rosalind Watts, wanted to put in place a framework and a community that would help to nurture and maintain that sense of connectedness over a much longer period of time. 

After successfully testing this process with a group of participants from the Imperial Psilocybin for Depressions trial, which was hosted by the Synthesis Institute, Dr Watts launched ACER Integration to bring the benefits to a much wider community around the world.

Guided by Nature

The Twelve Tree Teachers form a continual cycle of learning, a spiral of deepening enquiry to be repeated year after year. We start off with one of the trees from the Maple or Acer category: the Field Maple. This tree teaches us the fundamental principles of the ACER approach (Accept, Connect, Embody, Restore) and then we move into the cycle of meeting a new Tree Teacher every month. 

The idea for the Twelve Tree Teachers came after Dr Watts had a profound experience of connectedness with a Field Maple tree during a ‘dark night of the soul’. She became immersed in the wisdom of trees, finding her way to the Celtic Tree Calendar, the work of Glennie Kindred, Ian Siddons Heginworth and John O Donahue. As working with trees gradually revitalised her, she created a Twelve Tree Cycle that could guide others on an ongoing journey of reconnection.

A fated meeting with Philip Carr-Gomm enabled Dr Watts to align the ACER Cycle with the ancient wisdom of Druidry, and the Eightfold Wheel of the year. The current Twelve Tree Cycle includes Trees native to the British Isles, USA and Canada, but the spiral of enquiry they provoke can be embarked on by anyone, anywhere.
