[Tweeters] heat dome & invertebrates

[Steve Hampton]

Excellent point. I would guess there are water restrictions that would also
affect ag, wildlife areas, etc., depending on their water source.  I have
heard that the Yolo Bypass Wildlife Area near Sacramento is doing their
usual "shorebird fields", which can create shorebird habitat for thousands.
Also, some stormwater retention ponds are getting so low that they are
creating mudflats suitable for shorebirds.

It will be interesting to see how the invertebrate biomass and shorebird
foraging is around the Salish Sea this month. Are there any places with
annual surveys and data?
