Later, Staab wiped all color from his palette to focus on highly refined geometric line drawings on paper.Since 1983, he has worked exclusively in and with nature, making ephemeral environmental site installations that incorporate reflections and shadows, shifting light, and changing seasons.Bridging land and sky, the scope of the work reflects the artist's arm span, his upward reach, his stride, his size and strength.[4] One such example of this work is 'X' Intertwining, a public piece formerly located in Riverside Park in Milwaukee, Wisconsin, made of stinging nettles woven into ropes.Staab has since been invited to create installations in the United States, Canada, Brazil, Denmark, Japan, and Italy.
