For our EcoMyths segment, Kate Sackman joins us to talk with Robert Fahey from Morton Arboretum. They want us to know that &ldquo;treehugging is cool&rdquo; for us and the environment. Fahey studies forest ecosystems and urban forestry and admits to hugging trees, but clarifies that it&#39;s &quot;usually for research purposes.&quot;</p><p><iframe frameborder="no" height="450" scrolling="no" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/155848109&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;visual=true" width="100%"></iframe></p><p><strong><u>Urban Trees Cool Chicago Saving $44 million annually</u></strong></p><p>What&rsquo;s cool depends on who you&rsquo;re asking. James Dean was definitely cool, <a href="http://www.metrolyrics.com/cooler-than-me-lyrics-mike-posner.html">Mike Posner</a>, not so much, and tree hugging &ndash; well, again, it depends who you are asking.</p><p>Today on <em>Worldview</em>, Jerome McDonnell and I explored the topic of how trees cool our homes, our cities, and our planet. We invited <a href="http://www.mortonarb.org/science-conservation/scientists-and-staff/robert-t-fahey">Robert Fahey PhD</a>, an expert in forest ecosystems at the Morton Arboretum, to tell us about the amazing things that trees do as well as the threats to trees caused by the warming planet. As many know, carbon dioxide (CO2) occurs in the atmosphere naturally as part of the cycle of life on earth. But excess CO2 emitted into the atmosphere causes planetary temperatures to rise. Fahey explains that forests and trees absorb much of that carbon from the atmosphere, store it in their wood, and emit oxygen in return, making forests extremely important for mitigating climate change.</p><p>He described how forests around the world, including in Borneo, the Amazon, and Siberia, suffer the impacts of global temperature rise, such as fire, severe storm damage, and drought. In the Midwest and Eastern U.S., many of our native trees, such as oaks, are hearty in a broad range of temperatures, but remain vulnerable to insects and pathogens that thrive in warmer climates. These living threats include emerald ash borer in the Midwest and the mountain pine beetle which is devastating forests in the Mountain West. Fahey says that the management policy in large forests is to let trees adapt naturally. But in urban settings, we can select trees that are more resilient to various urban stresses.</p><p>In cities such as Chicago, &ldquo;trees are extremely important for reducing energy costs and cooling the city&rdquo; Fahey says. He said a recent study &ldquo;estimated that the urban forests in the Chicago region reduce energy costs by about $44 million per year&rdquo; in addition to reducing the amount of carbon released into the atmosphere due to less fossil fuel burned that would have been used to create that energy.</p><p><u><strong>One Green Thing</strong></u></p><p>Plant a native tree!

Actual size of adult ranges from 3/8 to 5/8 inches. The invasive beetle has destroyed tens of millions of ash trees over the past decade. (AP Photo/Minnesota Dept. of Natural Resources, File)" /></div><p>Emerald ash borer (EAB) is an exotic insect native to China and eastern Asia. The bug hopped a ride to the U.S. in cheap wood packing material more than ten years ago. First detected in Michigan in 2002, today EAB infestation is a problem in 19 states. Most recently in <a href="http://myemail.constantcontact.com/For-Immediate-Release--Save-Your-Ash-Trees---Learn-to-ID-EAB--.html?soid=1109594220206&amp;aid=hPdylZ4kTmU">New Hampshire</a>, the state&rsquo;s department of agriculture confirmed detection on April 5<sup>th</sup>.</p><p>Aside from feeding on leaves, the adult beetles do little harm. Ruin occurs when in larva stage, EAB</p><div class="image-insert-image ">&nbsp;</div><p>chew through trees and damage its vascular system &ndash; the tissue right under the tree bark that&rsquo;s responsible for transporting water and nutrients from the roots to the top leaves and branches.</p><p>Scientists say its continued spread across the country is most likely due to the sale of firewood from <a href="http://www.aphis.usda.gov/plant_health/plant_pest_info/emerald_ash_b/quarantine.shtml">quarantined</a> areas across state lines. Even worse: Stress from climate change, namely drought, makes the trees more vulnerable to EAB. North American ash trees have no natural resistance to this foreign guest.</p><p>Arborists explain with such a large food source for the pests, the problem is only expected to grow. According to one of the nation&rsquo;s largest tree care companies, The Care of Trees, Ash trees comprise 10 percent to 40 percent of local urban forests. Many ash trees were planted during the recent housing boom &ndash; creating a monoculture that makes them easy targets for EAB -- and they are natural reproducers.</p><p>So what to do? Initially, many communities took a wait and see approach, says Peter Gordon, city forester for Lake Forest, IL -- where 19 percent of the tree inventory is ash. EAB came to attention during the economic downturn, Gordon notes, and budget-strained municipalities had few resources for tree treatment.</p><div class="image-insert-image "><img alt="" class="image-original_image" height="181" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/AP1110260175558_1.jpg" style="float: right;" title="Forester Jeff Wiegert, of the NY State Department of Environmental Conservation, points out markings left from emerald ash borer larvae on an ash tree. (AP Photo/Mike Groll)" width="240" /></div><p>&ldquo;The strategy was to see how states, count[ies] and towns handled EAB where it was first discovered,&rdquo; he adds.&nbsp; &ldquo;But now we don&rsquo;t have as many options.&rdquo;</p><p>Indeed EAB is an epidemic and can&rsquo;t be ignored, says Fredric Miller, a professor of horticulture at Joliet Junior College and a research associate with the Morton Arboretum in Lisle, Ill.</p><p>&ldquo;If you choose not to do any treatment, you will be overrun,&rdquo; Miller says. &ldquo;What communities have to come to grips with is that either you are going to manage this on your schedule, or the insect will dictate the schedule.&rdquo; And that means, in part, cutting down lots of trees in our neighborhoods in an effort to stop or slow the spread of EAB.</p><p>Arborists explain the alternative for a badly infested tree &ndash; allowing it to die from EAB damage and then cutting it down &ndash; is worse, because it does nothing to prevent the beetle from paying a house visit to a neighboring tree. Also, Miller points out, dead ash trees are a dangerous liability and must be removed &ndash; they&rsquo;re structurally weak and can fall during wind or ice storms. Many of these trees line walkways and paths in neighborhoods and forest preserves.</p><p>But some trees can, and should, be saved with proper insecticide treatment, explains David Horvath, an arborist in suburban Chicago with The Care of Trees.</p><p>Horvath says that homeowners and municipalities are now charged with identifying &ldquo;valuable&rdquo; trees &ndash; generally larger (greater than 12 inches in diameter) that provide environmental benefits such as shade to decrease energy demand, a deep root system that mitigates storm water damage or simply beauty to the property.</p><p>Overall, an integrated approach &ndash; treatment, prevention and some targeted tree removal &ndash; is the best way to put the brakes on EAB, and avoid destroying urban forest, say Horvath and the other scientists EcoMyths interviewed.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/AP03041601077_0.jpg" style="width: 244px; height: 159px; float: left;" title="Crews cut down trees infected with the Emerald Ash Borer, north of Whitehouse, Ohio. (AP Photo/J.D. Pooley, File)" /></div><p>According to a 2011 article in the <a href="http://www.nrs.fs.fed.us/pubs/jrnl/2011/nrs_2011_kovacs_002.pdf">Journal of Environmental Management</a>, prevention and treatment may make more sense economically, too. The estimated cost of treatment, removal and replacement of EAB in all affected states from 2010 through 2020 is $12.5 billion. Prevention tactics (such as destroying egg-laying EAB and targeted tree removal) could slash those costs by up to $7.5 billion, the authors concluded.</p><p>In the Chicago area, for example, municipalities spend up to $1,100 to remove and replace one tree, according to a 2012 survey conducted by Miller and his team.&nbsp; He notes that the same tree can be treated with insecticides for more than 50 years at the same cost.</p><p>Insecticides may sound nasty, but remember the alternative: cutting down the tree or letting it die anyhow, while giving that nasty beetle a free pass for its next meal. Plus, when used correctly and responsibly, experts say, insecticides targeting EAB are not likely to harm humans or the environment.</p><p>How else are government and science addressing the spread of EAB? Interstate regulation prohibits the sale of firewood from <a href="http://www.aphis.usda.gov/plant_health/plant_pest_info/emerald_ash_b/quarantine.shtml">quarantined</a> areas. Also any wood packing material used for international trade must be fumigated or heat-treated, explains Kerry Britton, a national pathologist with the U.S. Forest Service who studies invasive forest pests.</p><p>Another strategy: Britton notes that researchers are trying to breed ash trees with natural resistance to EAB by crossing Asian ash trees that fight off the pest with vulnerable North American ash species.</p><p>&ldquo;By the time the beetle was detected, it could not be eradicated,&rdquo; Britton says. &ldquo;The goal now is to slow it down.&rdquo;</p><p><strong>One Green Thing You Can Do: </strong></p><p>Don&rsquo;t move firewood from <a href="http://www.aphis.usda.gov/plant_health/plant_pest_info/emerald_ash_b/quarantine.shtml">quarantined</a> areas. One study showed that EAB can establish on a credit card-size piece of bark.</p><p>Keep an eye out for EAB, whether in your yard or your neighborhood. Here&rsquo;s a <a href="http://www.extension.iastate.edu/pme/Publications/EAB/FAQSUL21AshTrees.pdf">helpful guide</a> to identifying ash trees and distinguishing between EAB and other problems. Realistically, your best bet is to call an <a href="http://www.tcia.org/">accredited tree care company</a> since early evidence of EAB damage occurs at the treetop level, where it&rsquo;s not visible to most folks. <strong>Now</strong> is the time to act. Treating trees by mid-May minimizes the damage by adult beetles, which emerge in the spring.

But earlier this week Cahan ran up against a real head-scratcher that hit close to home. Literally &ndash; the case in question began under a tree in her backyard.</p><p>And so Cahan arrived at the office on Monday with what she thought might be a telling piece of evidence: a seemingly once-beautiful maple leaf covered in pitch-black spots the size of quarters.</p><p>&ldquo;It looks like it got burned,&rdquo; said one WBEZ reporter. &ldquo;It looks sick,&rdquo; said another.</p><p>It was a disturbing sight, indeed.</p><p>Between <a href="http://www.wbez.org/news/low-water-lake-michigan-could-cause-problems-shipping-industry-104121" target="_blank">low water levels</a>, <a href="http://www.wbez.org/blogs/bez/2012-08/what-does-drought-do-ranch-full-grass-fed-cattle-101629" target="_blank">extreme drought</a>, and the fact that it reached nearly 70 degrees on December 3, it wasn&rsquo;t a stretch to imagine that some environmental funny business might be behind the splotchy-leaf dragnet of 2012. Plus, Cahan recently experienced the loss of most of her garden to what she described as an oozing, yellow mold. So there was reason to be worried.</p><p>It turns out the coal-colored stain on our city&rsquo;s autumnal gem is a) harmless, and b) not all that unusual.</p><p>The black spots on maple leaves, aptly named tar spots, are evidence of the fungus known as&nbsp;<em>rhytisma.</em></p><p>&ldquo;It looks awful, and it makes people concerned,&rdquo; said Sharon Yiesla, plant clinic assistant at the <a href="http://www.mortonarb.org/" target="_blank">Morton Arboretum</a>. &ldquo;But it&rsquo;s more of a cosmetic problem than a health problem. It makes the leaves look ugly.&rdquo;<img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/RS6778_007-scr.JPG" style="height: 150px; width: 200px; float: right;" title="Maple leaf with tar spots (WBEZ/Lewis Wallace)" /></p><p>She did say tar spots have been showing up more frequently in the region in the last few years, but did not recommend any treatment for the fungus. The best thing to do is thoroughly rake up and dispose of the afflicted leaves, Yiesla said. Otherwise, the fungal spores that stick around all winter may float up onto the fresh leaves come spring.</p><p>The emerald ash borer, on the other hand, &ldquo;that&rsquo;s a more serious problem,&rdquo; Yiesla said. Ash borers have devastated the ash population in Michigan, and they&rsquo;ve been digging away at Illinois ashes since 2006. The larvae of the ash borer get under the bark of ash trees and gnaw away at it, slowly cutting off ash trees from their water supply at the roots. In just two or three years, your ash can be grass.</p><p>Yiesla said ash borers can be stopped if you catch them early &ndash; but catching them isn&rsquo;t easy. They make a small hole the shape of a capital D in the trees bark, but other than that, they&rsquo;re invisible. A weak-looking ash, loss of leaves, or a sudden influx of hungry woodpeckers (who dig under the bark to eat the borers) can all be telltale signs.</p><p>Salt damage from ice melters used on roads and sidewalks is another concern this season.</p><p>&ldquo;As cars are going by, you&rsquo;ll get it spraying up onto the needles of an evergreen, and it can do physical damage to the needles,&rdquo; Yiesla explained. &ldquo;But then it also gets into the soil, and can do some harm at the root level.&rdquo;</p><p>The salt in the ground makes it harder for trees to absorb water.</p><p>Water absorption is particularly pressing given this summer&rsquo;s drought, which will likely affect next year&rsquo;s plant growth.</p><p>&ldquo;We might see reduced growth, reduced flowering, and weaker plants,&rdquo; Yiesla said. &ldquo;We&rsquo;re not getting much additional rain this fall, and who knows what snow will come this winter.&rdquo;</p><p>In other words, maple leaves with black spots are the least of her worries.</p></p> Mon, 03 Dec 2012 12:47:00 -0600 http://www.wbez.org/blogs/bez/2012-12/great-maple-leaf-mystery-104161 Morning Rehearsal: Chicago theater 4/26 http://www.wbez.org/blog/onstagebackstage/2011-04-26/morning-rehearsal-chicago-theater-426-85688 <img typeof="foaf:Image" src="http://llnw.wbez.org/blog/photo/2011-April/2011-04-26/ElNogalar_C.jpg" alt="" /><p><p style="text-align: center;"><img alt="" class="caption" src="http://llnw.wbez.org/blog/insert-image/2011-April/2011-04-26/ElNogalar_C.jpg" style="width: 400px; height: 292px;" title="The set of El Nogalar (Brian Sidney Bembridge)"></p><p>1.

Their average lifespan is less than ten years. That's compared to fifty or sixty years for their suburban cousins.<br> <br> Bryant Scharenbroch is a soil scientist with the Morton Arboretum. He said all those city roads and buildings make soil too dense.<br> <br> "When you compact the soil to make it suitable for infrastructure, you're also making it kind of a hostile environment for trees," he said."<br> <br> So scientists are testing out biochar, a sort of super-heated charcoal made from plant matter. Ancient Amazonians were using biochar on their crops centuries ago, but its affects on trees haven't been widely studied, said researcher Kelby Fite, with Bartlet Tree Experts.<br> <br> Biochar adds nutrients into the soil, like compost, but lasts a lot longer.<br> <br> "So compost may degrade in a matter of a handful of years, whereas biochar could be stable for hundreds, or even thousands of years," Fite said.<br> <br> The researchers will monitor sample trees in the Bucktown neighborhood for the next couple years.</p></p> Tue, 12 Apr 2011 18:39:00 -0500 http://www.wbez.org/story/scitech/environment/chicago-researches-look-lengthen-life-city-trees-85088 Conserving the tree canopy http://www.wbez.org/episode-segments/conserving-tree-canopy-0 <img typeof="foaf:Image" src="http://llnw.wbez.org/N15 Cloud forest.jpg" alt="" /><p><p>Rainforests are recognized and valued for their astounding biodiversity. They play an important role in reducing carbon in the atmosphere. Environmentalists continue to fight hard for rainforest conservation. But while most people like trees, it's hard to feel a connection with the vibrant world of rainforests.</p><p><a href="http://academic.evergreen.edu/n/nadkarnn/">Dr. Nalini Nadkarni</a> thinks making that connection is crucial for the rainforest's survival. Nadkarni is one of the world's leading tree forest ecologists. She teaches at Evergreen State College in Olympia, Washington. She also co-founded the <a href="http://academic.evergreen.edu/projects/ican/ican/">International Canopy Network</a> to help people engage with the canopies all around us.</p></p> Wed, 22 Dec 2010 15:00:00 -0600 http://www.wbez.org/episode-segments/conserving-tree-canopy-0
