If you have hemlock trees, please check them for hemlock woolley adelgid. If you don't have any lower branches, you clip a couple small branches and take a peak. When there is snow, you can try using bionoculars or zoom camera lenses! #HWA #hemlockwoollyadelgid #foresthealth #trees #InvasiveSpecies

Nope that's not snow. It's #hemlockwoollyadelgid aka #HWA which flourished from last winter's warm weather but hopefully the extreme #polarvortex knocked the population back this year!

DEC, OPRHP, and New York State Hemlock Initiative Announce Major Milestone in Hemlock Woolly Adelgid Biological Control
“Hemlocks are a foundation species in New York’s forests, providing critical habitat for wildlife, supporting water quality, and stabilizing soil on steep slopes,” said Justin Perry, DEC’s Invasive Species and Ecosystem Health Bureau Chief. “Their conservation is a priority for New York State, and successful biological control efforts like this collection strengthen ongoing, science-based work to manage HWA through integrated pest management strategies.”
