Landscape ecologists say pictures can be deceiving. What may appear pastoral today can%2C with rapid infill of development%2C transform ag and undeveloped open lands into suburbs where wildlife disappears. Huge swaths of the Gallatin Valley and many valleys in Greater Yellowstone have already been subdivided. The only question is if and when homes might appear. Then it becomes extremely expensive to protect what remains%2C despite heroic efforts by groups like local land trusts. Photo by Todd Wilkinson
