OakMapper - Sudden Oak Death Mapping

Welcome to OakMapper! Here you can find the most up-to-date data on locations of p. ramorum (the pathogen that causes sudden oak death (SOD)) in California. These official confirmations are shown in red on the maps. This site also functions as a citizen science portal and we would like you to help us collect information on the possible locations of sudden oak death in California. You can create a login, and once registered, you can tell us about possible SOD via the map interface, or by using the iPhone app. Your contributions will appear in yellow on the map. You can also create your own custom maps of the locations of sudden oak death. Please explore the site, and sign up!
