100 distinct wood species

Peter Raven, past president of American Association for the Advancement of Science, states, “We have driven the rate of extinction, the permanent loss of species, up several hundred times beyond historical levels, and are threatened with the loss of a majority of all species by the end of the 21st century.

Each puzzle piece was cut from 8/4 material (2 inch). In creating this piece, The completed puzzle has 100 pieces (minus 1). In creating this piece, I collected over 100 distinct species of wood. A small number were purchased from hardwood retailers (in these limited cases care was taken to insure sources were from sustainable harvest (FSC or plantation grown). The bulk of these specimens were gathered in small numbers from individual collections of wood workers, shipwrights, arborists, millers, and urban loggers.
