The use of transects to monitor changes in vegetation over a period of time has been practiced for decades. The methodology includes obtaining information about the species present, their health and percentage cover of foliage. With the advent of digital technology many researchers use cameras to record and analyse vegetation. Generally saltmarsh vegetation is relatively low in height (10 to 30 cm) and lends itself well to this approach. The methods in this section cover the set up of a transect, recording data and camera techniques.
