Ewan was Artist in Residence at the Nature in Art Gallery and Museum, Gloucester in 2015, 2016 and 2017. He is also Tree Artist for the Durham Wildlife Trust and Artist for the Sidmouth Arboretum.
He gives his drawings for the production of cards to support the following charities:

- York Museums Trust
- Sidmouth Arboretum
- Nature in Art Gallery and Museum (Twigworth, near Gloucester)
- Benefice of Debenham and Helmingham, Suffolk

If tree drawings can be supportive, Ewan is happy to help other charities.
