Hi Rogelio Rodriguez, These are perhaps more general in scope and limited in areas covered than you wanted, but for plant distributions in rhe US and Canada, by states and provinces, the following are useful.
http://plants.usda.gov/ (US and Canada) for species that are rare in some part of their range in US or Canada http://www.natureserve.org/explorer/servlet/NatureServe?init=Species Pat ---------------------------------------------------------- Patricia Swain, Ph.D. Community Ecologist Natural Heritage & Endangered Species Program Massachusetts Division of Fisheries & Wildlife 1 Rabbit Hill Road Westborough, MA 01581 508-389-6352 fax 508-389-7891 http://www.nhesp.org ____________________________________ from: ECOLOG-L Digest - 7 Oct 2009 to 8 Oct 2009 (#2009-278) Date: Thu, 8 Oct 2009 13:36:17 -0500 From: Rogelio Rodriguez <[email protected]> Subject: Database & Maps for Plant Distributions >Hi I'm trying to find a good source for plant distributions but for either single species or groups. I'm familiar with similar resources for a nimals such as MaNIS but I was wondering if there is one for plants that some herbariums have compiled where you can download data and map the specimens. Maybe any GIS layers for single species or groups I have layers on vegetation classification but looking for something more specific. Thanks Rogelio Rodriguez
