Books on bog ecology

Hey everyone! I was wondering if anyone had any recomendations for books on bog ecology? I'm located in Wisconsin so I'd like to learn more about bogs in the Northern US, but a general one will do as well. I guess ecology books on wetlands would do just as well....

Thanks y'all

I found tons of information on the internet. Just go to a search engine and look up building a bog. Most of the information is the same except for the depths of the bog and whether or not to punch holes in the lining. I went 14 inches deep and did not punch the holes in. My bog is doing very well.
