Submitter does not have a specimen
EDRR Status: Population assessed
Large heart shaped leaves with stems and runners that wrap around, and climb over the underlying plant, completely covering it so it is no longer distinguishable. I have not seen any flowers on it.
Thank you for submitting your report to the Oregon Invasives Hotline. I apologize that it has taken so long to get back to you regarding your hotline report. We recently were out on site to identify the weed in question and it has been identified as an infestation of Field bindweed, (Convoluvulus arvensis).
The Clackamas Soil and Water Conservation District is working with regional partners to map and catalog known infestations of invasive weeds and your report will help prioritize future control efforts.
Unfortunately, the resources required to control this invader are limited in relation to the overall need. As such we must rely upon landowners to initiate control on property they own or manage. We currently offer technical information and assistance to local landowners to help them develop a management strategy that is effective for their particular site conditions and needs.
I encourage you to work with your neighbors to address this invasive weed.
Please take a look at the links below for more information about Field bindweed.
