I know for certain because I've seen it, that when trees get covered with lichen, the next thing is their bark starts falling off, and before you know it, it's dead. Most lichen are indicators of clean air, but there are some that thrive on nitrogen pollution, which is what I believe we're seeing. Here are some posts with links to lichen research:<br /><br />http://witsendnj.blogspot.com/2011/03/balding-syndrome.html<br /><br />at the end of the video in this post are some shots of lichen in California that are really funny:<br /><br />http://witsendnj.blogspot.com/2011/12/harvard-forest-being-eaten-alive-by.html<br /><br />another:<br /><br />http://witsendnj.blogspot.com/2010/04/lichen-schmiken.htmlGail Zawackihttps://www.blogger.com/profile/01800944469843206253noreply@blogger.comtag:blogger.com,1999:blog-5549306427964459740.post-61288428084083846062013-06-16T15:07:39.259-04:002013-06-16T15:07:39.259-04:00I googled whether lichens are harmful to trees and...I googled whether lichens are harmful to trees and did not find any consensus. Some said that the presence of lichens indicated good air quality and not harmful to trees. Others claimed that the presence of lichens on tree bark were an indication of failing trees. No reasons given. Do you know of any credible research on this topic Gail?Ravi V.

So old he claims it must have lived through the Civil War. He was the only one there on a sunny warm day, it just fell down in a mighty collapse, like a collapsing wrestler letting gravity pin him to earth. <br /> My father saw that tree as his personal omen. Witnessing the fall gave it some poignant grace. rpaulihttps://www.blogger.com/profile/00016149709193595632noreply@blogger.comtag:blogger.com,1999:blog-5549306427964459740.post-24702522487182892712013-06-14T21:51:46.231-04:002013-06-14T21:51:46.231-04:00Oh, yes, I remember that study well, Michele!

In the case of emerald ash borer, vast numbers of trees are dying in urban and semi-urban areas as a result of this invading insect species. My personal guess is that the dying trees cause substantial level of anxiety among residents in these areas and that the cardiovascular symptoms are related to that anxiety. I’m certainly not an expert on medical matters but I understand that relationships between anxiety and these sorts of disorders are known to exist. Nevertheless, I would acknowledge that there might be other possibilities too…."<br /><br />Which strikes me as utterly idiotic. Stress from not having trees around is more of a medical factor than the increase in pollution from the huge amounts living trees absorb?<br /><br />grrrrrr...<br /><br />Catman, I have very similar impressions so far this season.<br /><br />Thanks again, David!Gail Zawackihttps://www.blogger.com/profile/01800944469843206253noreply@blogger.comtag:blogger.com,1999:blog-5549306427964459740.post-52005238806045402252013-06-14T21:33:13.994-04:002013-06-14T21:33:13.994-04:00Here in Georgia, with the very cool and wet spring...Here in Georgia, with the very cool and wet spring, the trees are attempting full foliage. Or at least fuller foliage. The ozone level has also been lower, I can tell because the leaves look greener and healthier than they have for years.<br /><br />But all of those green, heavy leaves put stress on the roots, trunks, limbs, and branches. With all the disease, and after the last 5 years of drought conditions, the trees are weak and something has to give. Two 30 year old oaks went down in past two weeks in a neighbor's wood lot.catman306https://www.blogger.com/profile/04670081770711560337noreply@blogger.comtag:blogger.com,1999:blog-5549306427964459740.post-9000535848545378902013-06-14T21:32:16.156-04:002013-06-14T21:32:16.156-04:00hi Gail,
from an article:
Comment 2, from NewsHour...hi Gail,<br />from an article:<br />Comment 2, from NewsHour viewer mollycruz: It strikes me that when trees go, roads and cars come, and I suspect air pollution could be responsible for the curve upward in diseases long associated with exhaust fumes. Did you look into the link between pollution and the death of both trees and humans?<br /><br />Donovan: I agree that the loss of trees may result in worse air quality. That's why we looked at two causes of death (cardiovascular and lower respiratory disease) that are influenced by air quality. However, I don't think this is because of increased development. That said, our results don't tell us for sure what mechanisms link trees and health. I can speculate, but this is a question that needs more study.<br /><br />THIS IS A QUESTION THAT NEEDS MORE STUDY????

They have lost their elasticity,the very thing that kept them alive and in the ground. For they can no longer "bend with the wind".<br />Earth's winds have not gotten stronger, over the past few years, but trees are obviously weaker.<br />what has become stronger, or more prevalent,is toxic, and phytotoxic air pollution.<br />David Lange<br />WindSpiritKeeper Wind Spirit Keeperhttps://www.blogger.com/profile/08593821563591272476noreply@blogger.com
