Agents of Change is an artists’ book, produced in the spirit of an exhibition catalog, as part of Cull.arbor.ation: Culling the Urban Forest. It explores urban forestry practices, environmental policy making, and the parasitic diseases and non-parasitic disorders that destroy trees. Agents of Change is printed two-sided and grows to 194 inches when fully open. It contains observances by the artists and a seven-inch vinyl record with tracks containing chain saw and wood chipping sound art. Photographic images in the book represent a time line of important political changes and speak to the loss of trees in the urban forest.
