Ted - Thanks for the response. We are north of the tulip poplar range here in Vermont, but I was forwarding a question to the list from a contact in North Carolina. In helping train a forest health survey crew in the high elevations of North Carolina back in June I saw serious dieback and death of several high elevation species, but did not have the opportunity to observe tulip poplar at lower elevations. Putting Denny Haldeman's question out to the list is one way to solicit observations to indicate whether or not his observations are local or indicative of a more widespread problem. So far three reports have come in (including yours) and none have indicated a problem with tulip poplar. My interest was also heightened by the fact that in Vermont I have been observing episodic leaf curling in several species of hardwoods and steady, light needle and leaf drop in almost all species since July of last year. When this was first noticed the ground was very wet and growing conditions were excellent so that it is very unlikely that the symptoms were drought related. Episodes of leaf curling have become more frequent and severe this summer while rates of leaf and needle drop have remained about the same. We are now experiencing what could be considered the start of drough conditions, but the leaf curling is still episodic and can be seen on a wide range of sites. Normally drought stess symptoms first appear on shallow soils on rocky ridges. Thanks again for your response. - Gerry Hawkes Woodstock, Vermont At 03:52 PM 8/8/97 -0700, Ted Kegebein wrote: >Gerry Hawkes wrote: >> >> Can anyone provide observations and/or explanations (see below). >> >> - Gerry Hawkes >> Woodstock, VT >> >> >Date: Sun, 3 Aug 1997 12:16:24 -0400 (EDT) >> >From: Denny Haldeman <denny@voyageronline.net> >> >To: Multiple recipients of list <da-general@essential.org> >> >Subject: Tulip poplar problems >> > >> <snip> >> >> >. . . .Can anyone tell me what in the hell is going on with >> >the Tulip Poplars.
