Public Reminded to Report Giant Hogweed Locations,
Especially as Plants Begin Blooming in WNY
New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos today announced that statewide efforts to control giant hogweed are making substantial headway in eradicating this large, invasive, and dangerous plant. The Giant Hogweed Program, managed by DEC's Division of Lands and Forests, is in its twelfth year and has eradicated the plants from 623 sites, with another 448 plant-free sites being monitored.
- Crews visited 1,993 sites to survey for or control giant hogweed;
- No plants were found for the third consecutive year at 118 sites, bringing the total number of eradicated sites to 623 - an increase of 25 percent from 2017;
- Of all sites previously treated for infestation, 43 percent (1,071 sites) had no plants in 2018;
- Crews removed approximately 678,000 plants from 1,271 sites during the 2018 field season;
- Stream surveys were conducted for the first time last year. Crews searched upstream for additional infestations that may have contributed to known giant hogweed locations from seeds being carried downstream. A two-person crew visited 317 stream-side properties, surveyed 37.6 miles of stream frontage, and found 76 new infestations;
- Of the sites statewide that still had plants, 71 percent (1,005) had less than 100 plants and are considered small sites that can be eradicated relatively quickly. DEC expects many more of these sites to have no new plants in the next few years; and
- Larger sites are responding well to control. Many larger sites that required herbicide treatment are now small enough to be treated by root cutting. Fewer sites have large flowering plants and, in general, sites are patchier than in previous years.
