On Hannah Fields is a short animated documentary by Lewis Heriz, responding to a community garden in Littleover - a suburb of Derby - in the middle of England. 

The film follows the trajectory of recovery, of both the land itself and the people who frequent it and tend to it. It is a representation of the cyclical and symbiotic approach to care, in contrast to the institutionalised system that the founder - an ex-NHS Psychiatric nurse - had experienced burnout within.
 
Lewis’ film includes black and white celluloid film, hand-processed in nettles which were weeded from Hannah Fields, and phytograms – images made through a chemical reaction between plants, photographic emulsion and the sun – made as part of a workshop with the garden's users and collaborators. The soundtrack comprises voices from members of the Hannah Fields community and sounds from the environments within the space.

Expanding on the drawn animation technique, Lewis says: 
 
“Much of the animation was created with just water, painted on 'magic paper' (originally used for Chinese calligraphy practice). You create a brief, dark line, which disappears quickly as it evaporates. I would photograph the image at different stages as I add to it, and as other elements naturally disappear... As well as being a metaphor for the transcience of life, it’s a gesture towards leaving no trace, and of not contributing to the unnecessary accumulation of stuff in the world.”
