During the winter of 1924-25, a count by species of the trees within the city limits of Mt. Pleasant was made by the students of the Biology Department of Iowa Wesleyan College. A recount of the trees in this area was made by the students during the winters of 1945-46-47. All trees over four inches in diameter at breast height were counted.
