Demographic estimation methods for plants with dormancy
M. Kery, K.B. Gregg
2004, Animal Biodiversity and Conservation (27) 129-131
Demographic studies in plants appear simple because unlike animals, plants do not run away. Plant individuals can be marked with, e.g., plastic tags, but often the coordinates of an individual may be sufficient to identify it. Vascular plants in temperate latitudes have a pronounced seasonal life–cycle, so most plant demographers...
