The primary purpose of this sampling method is to capture broad changes in the landscape and vegetation communities over seasons or years or to visually track restoration trajectories over time. This method collects georeferenced photos for use in site management (e.g., invasive species tracking) and long-term data collection. Each year (or seasonally), photograph(s) taken at fixed locations and bearings (e.g., Figure 1) are taken to ensure comparability. Panoramic photographs taken at a fixed start bearing can provide supplemental, landscape view, photograph comparison over time. If annually, the targeted time is during mid- to late summer during the peak wetland growing season, or during the appropriate peak growing season for the habitat being surveyed (e.g., spring for annuals).
