This is the southern edge of the Old woods, the open field under the purview of AAFC. At one time it was full of goldenrods, asters, grasses, dogwood shrubs, common milkweed, etc. and attracted all types of insects including monarch butterflies, as well as birds. But it also had thickets of the highly invasive pale swallowwort/dog-strangling vine and this is probably why it is now kept mowed.
