Side-on photography for vegetation analysis

Video demonstration of the use of side-on photography for vegetation analysis in salt marsh canopies. The method was originally developed for use in salt marshes by Möller (2000) and in parallel by Zehm et al. (2003) for grasslands, with further application for salt marshes reported by Möller (2006). Analysis of digital images obtained through the use of this method allows relative differences in the density, height, and structure of vegetation within a small area (in this case a rectangle of 0.2 x 0.6 m) to be compared across space or over time. Relationships between vegetation pixed density, as determined using this method, and biomass of salt marsh species have been suggested by Möller’s (2006) and Rupprecht et al.’s (2015) studies.
