Well, I am going to try out posting some mussel stuff because I am pretty excited about this tidbit of information. Ohioans and anyone interested in freshwater mussel conservation will be pretty excited about this I think.

Yesterday, while surveying out in Swan Creek, Lucas County OH, I came across a new live population of rayed beans. For those who do not know, the rayed bean is endangered throughout much of its range and is currently a federal candidate. To my knowledge, this is the first time the rayed bean has been found alive in Swan Creek. And, in addition, I found A LOT of fresh dead and weathered beans. I am hoping that this population may be more than a few isolated individuals, but it will require a lot more work to determine that. The bean is about an inch long and takes a lot of patience and attention to detail to survey accurately.

A professor had tipped me off this past year that beans might still exist in Swan Creek as he had found some fresh dead shells-in-a site in the late 1980s. Yesterday was only my 2nd survey and I covered only 200 feet in 2 hours. So who knows what the future holds, hopefully a lot of beans!
