Steve- Actually drought has occurred before in the Southwest, but not as seriously (duration, soil moisture deficit) in the last 600 years, and then quite some time before that. We are way outside of the natural range of variation here. Each region will experience global climate change differently. I'm not speaking for your area, as I don't claim to know much of your climate regime of late. I am familiar with the Southwest's. I don't subscribe to the "Global Warming hysteria", but I am allowing the evidence for global climate change to accumulate...in my view (and not only my view) it has reached the tipping point, and the rest will be reviewed historically. Reviewing our past posts has reacquainted me with how much easier it is to deny something than it is to prove something. They (our previous posts) have been thought provoking, and I agree with you to the point that the issue has become sufficiently politicized that the topic is muddled for most. -Don

Steve Springer From: [email protected] [mailto:[email protected]] On Behalf Of DON BERTOLETTE Sent: Sunday, May 31, 2009 4:06 PM To: [email protected] Subject: [ENTS] Re: ENTS in the news Bob- In the west in general and surely in Colorado, the media I attend to describes the plight of the high elevation forests, particularly the pines, in (what our fellow forum member Steve Springer denies) at least a severe prolonged drought, and perhaps one of the signs of global climate change. Gradient analysis may not benefit much of the eastern forest, but for the western forests where a watershed may contain an entire elevational gradient, forests are differentially subject to moisture stress, and are showing higher mortality than would be found in the natural range of variation. If your travels take you into the higher elevations where whitebark pines are found, I'd be interested in a first hand account of their general health. The high elevation pines I've followed in the high Sierras (foxtail, bristlecone, whitebark, sugar, western white) are taking a hit, with potential catastrophy waiting with each monsoonal wave of lightning storms, due to increased downed and coarse woody debris. In two weeks, I'll be assisting a friend in nominating a Kenai Birch for the Alaska Register, and since the National Register doesn't list one, perhaps we'll be nominating a National champion! -Don Date: Sun, 31 May 2009 19:38:23 +0000 From: [email protected] To: [email protected] Subject: [ENTS] Re: ENTS in the news Don, The day will come when AFs will be lauding the Pennsylvania and Alaska champion tree programs - and for good reason. Well, tomorrow, it is off to Colorado Monica and I go. I hope to report from the field as I go.
