There has been a population explosion of amber snails in the 2009 tree area. They are climbing all over the grass and meadow plants. There are so many you have to watch where you step. It's strange that they only seem to be in that area and in the adjacent bushy area. There is no noticeable concentration in the 2010 or 2011 or 2013 areas or in the grass across the road. I tried to estimate how many there must be in the concentration by counting the number in three test areas chosen at random. In one one meter square area in the strip normally mowed but not yet cut this year (close to the forest) there were 23 snails, in a second in the bushy area there were 50 and in a third in the 2009 area there were 10. The total area is about 2000 square meters so there are probably tens of thousands of amber snails climbing all over the meadow.
One that climbed to the top of the flowering kentucky bluegrass. In the background are two snails that might be mating.
A fairly clear picture of one on a dandelion leaf.
A whole group at one of their typical hangout spots: a clump of fescue.
