    That is about as far as I got. Client was worried that the trees were not doing well and had to be cut down. Her worries were some kind of borer, early leaf drop, and neighbors advise.

    This is about as far as I got with tree I’d B. Pencils ‘lacinita’ https://landscapeplants.oregonstate.edu/plants/betula-pendula-laciniata

    The bugs look like ladybugs in their intermediate stage, perhaps they were sprayed?

    Yeah lady bug pupa.

    Bronze birch borer is a major problem on imported birches but not sure if its a problem by you. D shaped exit holes

    Didn’t see any signs of bbb, looked for the exit holes. Just saw typical sap suckers. Where on the stem do they tend to exit?

    Start up high, perhaps around 1-2" stems and eventually go after trunks when severe.

    Sweet looks like I do get to climb them after all. Anything other than cultural practices and systemics if they are there?

    Not a fan of summer drought so cultural as you mentioned. I believe pretty susceptible to atmospheric pollution as well

    Be mindful that if Agrilus is the case, sapwood strength loss is likely

    We were very droughty this year, blessed to have good air quality (even though we were choking on wildfire smoke all summer).
    Also these trees are within 50 yards from the sound, on a sand spit. The whole property floods with the winter rains and high tides raising the water table. The water drains in a matter of days (not weeks or months).
    Drainage work is on the books, and I recommended arbor chips/RCX + vertical mulching
