It is well-understood that fine-scale habitat characteristics such as rock size, talus area, and availability of high-quality forage within and in the immediate vicinity of talus play an important role in pika occupancy and population persistence. These metrics are difficult to impossible to gather from satellite imagery and are both physically challenging and time-consuming to accurately quantify in the field. This pilot study aims to use multispectral drone imagery to overcome many of these challenges. Specifically, we assess whether it is feasible to effectively characterize rock size, habitat area and configuration, amount of vegetation within the talus and its immediate vicinity, as well as whether we can distinguish among the plant functional groups (forbs, graminoids, shrubs, and trees) well enough to accurately quantify abundance of each. High resolution drone imagery has the potential to greatly increase our ability to assess fine-scale American pika habitat quality. | |||
