Thus the
collections made at Mt. Aeolus and around the Homestead (1965 - 2004) have added
15 county landsnail records (total now 42 of the state's 54; a little over 77%),
of which five are new Vermont state records, which now makes 20 of these Vermont
species "unique" to Bennington Co. These addenda further dwarf second-place
Windsor (42 and 20 vs. 20 and [now] 3 respectively).
While the obvious cause to this geographic inequity is bias
in collection effort, this account demonstrates the scope of poverty in
knowledge of a part of natural history - and that a practical remedy is
available. Further, it chronicles the process and outcome of a strategic
collection plan - in this case based on the anticipated recycling of a calcium
resource that lay biologically dormant for nearly half a billion years.
