Bristol Food for Free is an online database of edible plants in Bristol. The website generates a map of any of the 113 species identified by its authors. Plants rooted in private lots are included if they branch into public space. The website also contains photo-documentation of potential planting sites selected for suitability. Bristol Food for Free allows inexperienced foragers to find fresh fruits and vegetables quickly and safely.
