Mira Lehr, a versatile Florida artist who helped found an early cooperative for women artists, and whose paintings, sculptures and installations often reflected her concerns about environmental degradation, died on Jan. 24 in Miami Beach. She was 88.

She was adventurous in her artistic explorations. Some of her work used Japanese rice paper. She created mangrove labyrinths out of rope and steel that exhibition visitors could walk through. Some of her more recent works involved fire. She would burn holes in canvases or ignite strings of gunpowder on them to create the appearance of vines and other effects. Her work frequently drew on the natural world, invoking foliage, birds, jellyfish, reefs, the ocean — the beauty of nature and the threats to it.
