Bee BioBlitz

Oswego Lake Watershed Council sponsored a Bee BioBlitz to identify as many pollinators in our community as possible over a three hour period from 9:00 am to noon on May 11, 2024.

They used iNaturalist (link below) to organize and help identify bees and other insects or animals that are found on flowers during the BioBlitz.  

Plans for that morning:

  • Meet at the outdoor classroom at Lake Oswego High School at 9:00
  • Get instructions and form groups to canvas an area – you pick where you want to go
  • Spend the next 2 ½ hours looking for flowers with bees with your group
  • Return to the outdoor classroom to share your best finds

Orange Hawkweed

Weed of the Month: Orange Hawkweed

Orange hawkweed (Hieracium aurantiacum) is a relatively new invasive weed in Clackamas County and we are working to keep it from becoming a common problem for landowners!

Orange hawkweed is a class A noxious weed here in Oregon, which means it is a “weed of known economic importance which occurs in small enough infestations to make eradication or containment possible” Class A noxious weeds are of such importance that you are required by law to report them to the Oregon Department of Agriculture, Noxious Weed Program within 48 hours of discovery.
