The New England Plant Conservation Program (NEPCoP) regional rare plant list, Flora Conservanda: New England, identifies higher vascular plant taxa (i.e., trilcolpates) in need of regional conservation. The first list, published in the Summer 1996 issue of Rhodora, identified 574 taxa in five divisions. As with the original publication, the data for this update were provided by the New England state Natural Heritage Programs (or equivalents). This update, completed in 2009–2012 by the New England Flora Committee of NEPCoP, is built on data as up-to-date as possible and is comprised of 593 taxa in five divisions: Division 1—Globally Rare Taxa (62 taxa); Divisions 2 and 2(a)—Regionally Rare Taxa (325); Division 3—Locally Rare Taxa (57); Division 4—Historic Taxa (96); and Division Indeterminate—Presumed Rare, but Confirmation Required (IND.; 53).
