The P/V Basin is characterized at Level III as the Willamette Valley – Ecoregion 3. At Level IV it is 3a. The major distinguishing feature is in the soil structure as a result of glacial alluvium deposits.
I traveled the bottomland areas of Scappoose and took my first hike around the Oak Island trail since it opened in May. There weren’t any surprises but i did observe my first Purple Martins of the year and got to hang out with a couple of territorial Chats. Out in the open in the Crown Z marshes was a Bittern — too far away for any more than a documentary (read bad) photo.
I did come across what i believe to be Blue Mustard (Chorispora tenella) which seems a bit out of place as it is known more as an east side invasive.
I only saw a few Cabbage Whites and a lone Tiger Swallowtail. Out at the Oak Island trail and Sturgeon Lake interface there were quite a few California and Blue-eyed Darners, but neither would settle down for a photo. This area is usually pretty good for quite a diverse odonate population — just not yet i guess.
