Mapping Distribution in Oklahoma and Raising Awareness: Purple Loosestrife (Lythrum salicaria), Multiflora Rose (Rosa multiflora), and Japanese Honeysuckle (Lonicera japonica)
Main Article Content
Abstract
This paper includes updated Oklahoma distribution maps and informational fact sheets for purple loosestrife, multiflora rose, and Japanese honeysuckle to promote awareness of invasive plant issues. The current information on the Internet contains discrepancies concerning the county-level distribution data of these three invasive plants in Oklahoma. To gain a more accurate dataset, the authors created a survey and sent it to Oklahoma State University Extension Educators, Master Gardeners, Oklahoma Association of Conservation Districts, and other knowledgeable, credible parties across Oklahoma. Once survey data were compiled, 3 distribution maps were created and 6 unique fact sheets were produced with the updated information. From the 22 survey responses, 7 new county records were documented and mapped. Two new sightings were documented for purple loosestrife in Canadian County and Rogers County; 4 new sightings were documented for multiflora rose in the counties of Atoka, Johnston, Payne, and Pushmataha; and 1 new sighting was documented for Japanese honeysuckle in Garfield County. The findings in this research detail the need for updated distribution maps and increased education to prevent the spread of problem species and provide the public with methods of eradication.
