The number of forested acres that have been certified as sustainable is growing in the US. Forest2Market recently plotted the acres certified under each of the three major certification schemes–the Sustainable Forestry Initiative (SFI), the Forest Stewardship Council (FSC) and the American Tree Farm System (ATFS)–by state and as a percentage of total forested acres.
what is the date on the informatin provided? Nice graphs of the certfication concentration.
The data was either publically available on the certifying body’s website or was provided to us by the certifying body. It was current as of 09/2011.
My first reaction was great info, I’m glad you took the time to research this data. It’s good to know the status of our forests in relation to the various certification systems.
Then, of course, I have to look at my own state, Maryland. And Maryland is not listed at all. Many don’t think of Maryland as a timber producing state and by comparison to Pennsylvania or West Virginia they would be correct. But we do have over 200,000 acres of our State Forest system certified by both FSC and SFI since 2003. My work is to maintain our certification program for the MD DNR Forest Service, so this is important to me.
So, was the plan for your study to include all states with certified forest lands or did you simply sample some of the states? Without the Maryland data it does skew the Northeast figures. If you have plans to update your information, I would be glad to provide you with our state data.
Again, great work, just wish you had included us in the data.

Nice graphs of the certfication concentration.Any similar graph of chain of custody certification?
