Wilderness managers and rangers use a variety of monitoring techniques to document changes in vegetation, soil, and resource impacts over a period of years. Repeat photography is one effective method to document site conditions. Taking photographs from the ground at eye level limits the camera's view (figure 1). When the camera is 8 to 14 ft above the ground, the view can encompass more (figure 2). This tech tip describes two systems for accurately raising the camera to better view site conditions.
