Plants of Northwest Arkansas, U.S.A.

Northwest Arkansas is now recognized as the 14th fastest growing metropolitan area in the United States. The population of the region doubled between 1990 and 2010 and is now adding more than 1,000 people per month. Most of this growth has occurred in Benton and Washington counties. As a result of this rapid growth, there is unprecedented interest in incorporating conservation-related information as the region plans for future growth.

It is already known that Benton and Washington counties are among the most biologically diverse in the state, but no comprehensive inventory has been conducted for either county. The Arkansas Natural Heritage Commission (ANHC) is embarking on this inventory now, with the ultimate goal of identifying the highest priority areas and/or habitats for conservation. The first step in this process is to gather all available information on what lives where. A treasure trove of herbarium specimens exists from these counties but very little of the label data have been digitized. That’s where you can help the scientists of the ANHC as they explore the biological diversity of Northwest Arkansas.
