Testing the forage preference of the American pika (Ochotona princeps) for use in connectivity corridors in the Washington Cascades
One of the aims of the Snoqualmie Pass East Project (SPEP) in the Cascades of central Washington is to construct nearly 30 wildlife crossing structures along a 15-mile stretch of Interstate-90. American pikas (<em>Ochotona princeps</em>) are being monitored for the SPEP because they have specific …
