Gerhardt has written about walking and experiential learning, civic engagement and citizen science; about human-animal-environment entanglement; about petro-cultures and petro-landscapes, e.g. plastic and the Pacific; about sea level rise and islands; and about future shorelines.
She has led walking tours, with both classes and the public, revealing the past histories of urban landscapes, considering how the present-day environment came to be shaped, and imagining possible futures.
