Conifers of Eastern North America


I put this together when I was working on the "Field Guide to Trees of Eastern North America," and the first order of business was to sort out the eastern species, defined roughly as species occurring in the U.S. and Canada east of the 100th meridian of longitude. I prepared this page mostly to help myself with that process.
