Hi, Dave-
Did the damage to the Beeches occur just in the last few days, that is,
was there no damage before the recent very cold nights?
You may want to consider the Beech Leaf-mining Weevil, /Orchestes fagi/.
It has killed many beeches here in the Waverley area. Surviving beeches
in my neighbourhood are all showing obvious leaf damage this Spring.

<div>Hi All,</div>
<div> Further on cold injury; by mid afternoon on June 5, Beech
leaves from ground level to beyond head height had appreciable
brownish patches in that Beech grove at about the highest point
of Beech Hill road. I am sure they will shrug it off.</div>
<div> Today along the east end of Brooklyn St. Five-fingered
Ivy damage ranged from crisp brown to unaffected and just east
of where the rail bed crosses the road a fairly large patch of
Spreading Dogbane was noticeably browned. With its extensive

inconvenience. Several small patches of Japanese Knotweed also
