Scientist Advocates Tree Selection for Ecofunctions

Diana Beresford-Kroeger says there are many unseen chemical relationships between trees, chemicals they produce, pollinators and pests are going on in the world around us.

She refers to herself as a "renegade scientist" "[trying] to bring together aboriginal healing, Western medicine and botany to advocate an unusual role for trees"

Bioplanning uses natural chemicals rather than synthetic ones by reforesting cities and rural areas with trees according to the medicinal, environmental, nutritional, pesticidal and herbicidal properties she claims for them, which she calls ecofunctions.
