IMPROVING SURVEY METHODS FOR THE DETECTION OF GIANT HOGWEED INPENNSYLVANIA. I.D. Bowers*, M.A. Bravo, and J. Zoschg, Penn State University, UniversityPark, PA (1)ABSTRACTGiant Hogweed (Heracleum mantegazzianum Sommier & Levier) was first recognizedby the federal government as a noxious weed in 1983. It originated in the caucusmountains of Asia. The infestation in the United States is the product of homeownersgrowing the plant in their gardens as an ornamental. The seeds then spread intoroadside ditches, streams, etc. via water dispersion and birds. Populations have beenfound in 16 states. The Pennsylvania Department of Agriculture, in conjunction with theUnited States Department of Agriculture, started its Giant Hogweed EradicationProgram in 1998. Since then over 500 sites have been found and treated inPennsylvania in 17 counties. More than 55% of the populations are located in ErieCounty. In March, 2010 Pennsylvania had identified 296 sites for declaring officiallyeradicated. Many of these sites were known to be inactive for more than 7 years. PDAhas adopted a three year negative seedbank followed by three years of follow-upsurveys as the standard for officially releasing a site as eradicated.Each season, the PDA hires a seasonal giant hogweed (GH) field position for ErieCounty and surrounding counties. This person is responsible for 1) managing the stategiant hogweed hotline and 2) surveying all known active sites and 3) surveying as manyreleased sites and hotline call locations as possible between May and August for thepresence of the noxious weed. Many of the sites are in very difficult to reach locationsand the plant, in its cotyledon and early rosette stage, can be easily overlooked. Toassist the surveyors in locating GH, a database of addresses, property owners contactinformation, GPS coordinates, and site descriptors has been compiled. However,addresses change, landowners move, and in some cases, the landscape itself iscompletely changed. These factors and the lack of site location knowledge in new hiresmake finding the correct locations very challenging. State-wide, 162 active and 262released sites were visited. Fifty-two of the 166 active sites were positive for gianthogweed plants and 10 new sites were detected. In addition, 14 released sites were rediscovered to be active.Given that a single GH plant can produce more than 10,000 viable seeds the PDA isworking to improve its survey and detection methods to address the correlation of time(7-12 years since site was released) and re-discovering a released site with the dataavailable. This paper summarizes the materials and methods used by the Erie CountyGH hire to find 88% of 279 released sites through follow-up visits and 98% of 101 activesites in the assigned 4 counties and the relationship between surveying methods andsuccessful eradication of spatially related populations. By improving and expandingupon the survey methodology used to re-locate released sites of GH and to detect newlocations, 9 released sites were rediscovered that were still active and 6 new sites werefound that were spatially related to known active sites. This information will be used toprioritize surveys of released sites in 2011 and in developing future survey methodologyfor noxious weed detections.1
