Large scale impacts of herbivory on vegetation

This WP differs from the others by being focused on a method, which allows us to move from the inevitably small scale of experimental studies to the scales relevant for the larger spatial scales at which the phenomena we ultimately wish to study operate. This is thus a service WP, connected to most others. The connection to large scale vegetation patterns, ground albedo and snow melt are the most obvious ones, but even issues related to animals or rare plants, which can only be detected in field at close range, can be approached by remote sensing techniques, since the vitality of plant and animal populations is often connected to such vegetation characteristics, which can be detected from satellite images, if ground truths tell which vegetation types are favorable resp. unfavorable for the organisms of interest.
