Austin Peay State University Botanical Garden showcases area’s rare and endangered plants

 

Austin Peay State University - APSUClarksville, TN – A few years ago, three tall, flowering cherry trees grew on the western side of Austin Peay State University’s Sundquist Science Complex. They provided a nice, welcoming entry into the building, but in 2007, Tennessee suffered from a record-setting drought.

Temperatures reached 113 degrees Fahrenheit that summer, and by the fall, the 20-foot tall trees were dead.

NASA scientists study changes to Earth’s Ozone levels

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth’s atmosphere probably won’t be affected much by projected future strengthening of the circulating winds that transport ozone between Earth’s two lowest atmospheric layers.

The finding is good news, since human and plant health are harmed by exposure to ozone near the ground. Significant increases in ozone in Earth’s lowest atmospheric layer, the troposphere, would also lead to additional climate warming because ozone is a greenhouse gas.

Astronauts aboard the International Space Station captured this photograph of Earth's atmospheric layers on July 31, 2011, revealing the troposphere (orange-red) to the stratosphere and above. Earth-observing instruments in space allow scientists to better understand the chemistry and dynamics occurring within and between these layers. (NASA/JSC Gateway to Astronaut Photography of Earth)

As of August 27th, CAL FIRE (California Department of Forestry and Fire Protection) reports that the fire, which started August 17th, had consumed nearly 180,000 acres, making it the seventh largest wildfire in California’s recorded history.

The fire is one of 10 active major wildfires burning across California as of August 27th.

Visible image of California's Rim Fire acquired Aug. 23rd, 2013 by the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra spacecraft, showing extensive, brownish smoke. The imaged area measures 236 by 215 miles (380 by 346 kilometers). (Image credit: NASA/GSFC/LaRC/JPL, MISR Team)

Tennessee Department of Agriculture says Emerald Ash Borer findings continue to spread

 

The Tennessee Department of AgricultureNashville, TN – Emerald Ash Borer, an invasive insect that destroys ash trees, has been found in Jackson and Scott counties. The identification was made recently and has been confirmed by USDA.

Both counties will now be placed under quarantine. Earlier this summer, Hamilton County was also placed under quarantine when EAB was found in trees near a rail hub in Chattanooga, TN.

Tennessee Department of Agriculture Division reports Emerald Ash Borer found in Hamilton County

 

Tennessee Department of AgricultureNashville, TN – Emerald Ash Borer, an invasive insect that destroys ash trees, has been found in Hamilton County. The identification was made recently and has been confirmed by USDA.

The find in Hamilton County is of particular concern because it is not adjacent to the already quarantined areas in East Tennessee. At least a dozen trees adjacent to the rail lines in Chattanooga and an EAB trap located in a park near the rail hub tested positive for the insect.
