Metro Parks does not allow foraging, collections or removal of any plant, mineral or live materials throughout Metro Parks, with the exception being leaves, mushrooms, fruits and seeds in general picnic areas and other regularly mowed surfaces. The only exception is that mushroom foraging is allowed in the Public Hunting Area at Battelle Darby Creek Metro Park, but only from March 1st-August 31st.
We do sometimes offer programming around Ohio's wild edibles, and for these, collection is permitted for a specific Metro Parks program with a designated team member. You can always view our programs on our website here.
