Subject: [obol] farmland transition
As Lars mentions, much of the regional agricultural land, especially at
least in the northern half of the Willamette Valley, is transitioning into
long-term perennial crops such as hazelnut orchards, grapes, blueberries
and hops in the last few years, and nursery stock before the 2008 economic
crisis. This use is mostly coming from grass seed and declining vegetable
acreage such as corn, peas and beans.

This is a contributing reason for the regional decline in Meadowlark,
Horned Larks, Northern Harrier, SE Owls, American Pipits, etc .... which we
pretty much missed all on our Silverton CBC last Friday.

BTW, I had a flurry of kinglet and chickadee activity, along with an
aggravated Hermit Thrush yesterday, obviously trying to harass a small owl
(IMO) that I could never see, in some dense brush at our place.
