Today Steph and I identified and measured the DBH of trees inside our plots. We noticed that the cemetery tree population is predominately older white pine, and the homestead is mostly young red maple trees. We think that this is because the white pine had a mast year at the cemetery site, while the red maples had a mast year at the homestead. A mast year is when a tree produces an enormous amount of seed, and only occurs once every few years.
I don't have any pictures of Steph and I measuring DBH, so here is a picture of Katherine measuring the DBH at her site.
Tomorrow we will head out into the field to build the cairns at the five sites. The cairns will serve as markers for our tour of the Barrington Headwaters.
Enjoy the sun!
Katie

The difference in tree species at the two sites is fascinating. What else could explain the difference?
Great photo! I can't wait to see these cairns you are building! -Rena
