Boundary Brook Nature Park on a warm and sunny October Saturday. Helen hosted and we were joined by Lucy and Andrew who volunteer at the nature park. Andrew trapezes (is that a verb?) in Flo Park. Always interesting people and high fliers at GG Oxford. Two tasks were on offer. Lucy and Andrew raked and tidied some recently mown meadow while Helen and I dug up overgrown sedge around a pond to let the light back in. We also felled a willow tree. It was one of those really satisfying "before and after" tasks.
