As our numbers soar, human choices, cultures, habits and desires define more and more of what happens in the earth's ecosytem, which species mutiply, which ones go extinct. My ecosystem work seeks to create an active culture of informed involvement in the living world. It involves exhaustive research about specific human- impacted ecosystems and about the particular needs of certain species. The canvasses I use, such as nesting houses or basking perches, often replace ecosystem infrastructure lost to the needs or the whims of human beings.
