Digital Cameras Aid Research

Aerial surveys become a way of routinely checking areas burned by wildfires or invaded by pests or weeds, and digital imagery is a major part of the technique.

Digital image from 300 feet shows arrow-leaf balsamroot on a slope in Wyoming.
Image taken from about 300 feet above the ground. The blooming plant, growing on a slope in Wyoming, is arrow-leaf balsamroot (Balsamorizha sagittata). A photo taken later that year showed that this area had become covered with cheatgrass (Bromus tectorum), an invasive weed that increases the chance of wildfire.
