For her series Index, Deanna M. Witman collects plant samples from a riverbank near her home on the coast of Maine and creates cameraless photographic documents of life that will one day be lost to climate change. Witman has written, "Reminiscent of herbarium records, the flora are memorialized and serve as a baseline against the impending change of increasing temperatures and rising waters. My small area of intertidal marsh will not be spared and will bear impact of these changes."
