I came across a great field book on trees. Its called the " Sibley Guide to Trees". It has helped me with my research studies on the GoZero carbon sequestration plots here at Marais des Cygnes NWR in Kansas.
I am not from the area and have not seen many of the trees here in my life. To be able to grab my book and narrow down to the exact species of tree I am looking at within seconds is a time saver and has greatly expanded my ID skills.
