I am trying to get a grasp on the dynamics of wetland vegetation between wet and dry years. I started monitoring vegetation in a wetland during a dry spell but from the preceding wetter years I have only photographs, even though individal species are recognizable from these photographs. Are there ways in which to use these photographs still in a systematic manner ?
Typha species (found in swamps) show clear differences between seasons in photographs
See my paper:

Hello. Is there perhaps some way that you could map (using GIS) the distributions of the identified plants based on your photographs from previous years, quantify the area they cover, and then compare to current coverage maps?
I am using a different approach with photographs, marked transects where I take photos pointed downwards at defined intervals. Moving zones can then be watched as the wetland dries and wets. In areas away from people I also use remote cameras mounted high pointed downwards which take a photo every day at noon.
