The book and exhibition include research papers and ephemera, all sorts of things that I collected on my travels—for example, interesting rocks, maps, quirky memorablia, and x-rays from when I slipped and broke my wrist in Sri Lanka when going to visit a tree there. All are culled from a whole decade’s worth of research, travels all over the world, and thousands of negatives. It was important to me to illustrate the layers of the project—some of the messy underbelly, if you will, and not just formal, final images on their own. The photographs themselves, mostly 44x54-inch prints and some smaller-sized editions, are art objects that are one component of this layered work. I approached the photographs of the organisms themselves more as portraits than as landscapes.
