Woolland Woods, Dorset. Landscape photographer of the year 2020. “Taken in spring of 2018 in a wooded area close to Milborne St Andrew in Dorset, this was the third visit to the area in a matter of days.

The low shooting position allowed more emphasis to be placed on the wild garlic and pathway”. (Photo by Chris Frost/UK Landscape Photographer of the Year 2020)
