Study Shows Stiltgrass Invasion May Facilitate Invasion by Garlic Mustard

Photo by S. Luke Flory
New results provide experimental evidence that an initial plant invasion associated with suppression of resident species and increased resource availability can facilitate a secondary invasion. Such positive interactions among species with similar habitat requirements, but offset phenologies, may exacerbate invasions and their impacts on native ecosystems.

A study conducted by S. Luke Flory and Jonathan Bauer used a long-term field experiment to test for indirect facilitation by Microstegium vimineum (stiltgrass) on a secondary invasion of Alliaria petiolata (garlic mustard). These species represent two of the most widespread and problematic invasive plant species in eastern North America. They found that Alliaria produced seven times more biomass and nearly five times more fruit in plots that had previously been invaded by Microstegium­. In addition, Microstegium-invaded plots had substantially less resident biomass than controls, and very little Microstegium early in the growing season when Alliaria is most productive, presumably due to the direct effects of Microstegium in prior years.

The study experimentally demonstrates that Microstegium can facilitate Alliaria across a range of disturbance regimes. Greater growth and reproduction of Alliaria in Microstegium-invaded plots may be indirectly facilitated by Microstegium’s suppression of shared resident competitors and associated increases in resource availability, although other mechanisms are possible. Understanding how direct and indirect interactions among species, particularly non-native invasive species, might structure communities is a primary need in ecology.

Tawny Crazy Ant Found in Southwest Georgia

A UGA Today article by Sharon Dowdy reports that the tawny crazy ant, Nylanderia fulva, has been reported in Dougherty County by the County Extension Agent, James Morgan. They have already been found in Texas, Florida, Mississippi and Louisiana, but this is the first report of an occurrence in Georgia.

They have also been called crazy raspberry ant. They are referred to as crazy, because they travel in an irregular pattern. Tawny crazy ants have been known to displace all other ant species, including fire ants, in areas they infest. They cause damage by killing small livestock and shorting out electrical systems. In addition they become a nuisance for homeowners, limiting use of  outdoor areas by both people and their pets.

Natural Resources - Division of Forestry,
The invasive forest insect emerald ash borer (EAB), Agrilus planipennis, (Order Coleoptera: Family: Buprestidae) has been found in DeKalb and Fulton counties. The attached announcement from The Georgia Forestry Commission provides an overview of the situation in Georgia. The Center for Invasive Species and Ecosystem Health, University of Georgia, is a member of the Georgia Invasive Species Task Force and has been involved in the development of the announcement and will be providing educational information and educational programming as needed and appropriate.

EAB is a serious tree pest that has caused havoc and has killed multiple millions of ash trees across a wide swath of the upper U.S. mid-West and Canada. EAB kills trees in both rural and urban forests. EAB is a Federally Regulated Pest and thus, there are several actions related to transport of wood products and materials containing wood that are regulated by Federal and State-laws that may be of more significance to Georgia than the potential loss of ash trees.

Video - Cultivating Awareness: Ornamental Plants Invading Natural Areas

Midwest Invasive Plant Network  and Great Lakes Early Detection Network published a video "Cultivating Awareness: Ornamental Plants Invading Natural Areas" on Jul 15, 2013. Well done and very informative.

"Invasive plants are species that are non-native and cause or are likely to cause harm to the economy, the environment, or human health. Some popular ornamental plants are becoming invasive in natural areas. This video demonstrates the impacts of these species on natural areas in the Midwest and provides information on how to make good choices for landscaping." by Midwest Invasive Plant Network.

Although this video targets the invasive species problems in the Midwest, the issues are the same or very similar in other regions. A lot of information is packed into just under 14 minutes.

The smartphone app 'Landscape Alternatives' is now available for iPhone and iPad with the Android version available very soon.

In addition to the 'Landscape Alternatives' smartphone app, a smartphone has been created for collecting and reporting data on invasive species in the Midwest. Smartphone apps have been created to make it easy to collect and report data on invasive species for many regions across North America. The apps here send the data to EDDMapS, Early Detection and Distribution Mapping System. EDDMapS provides a picture of the distribution of invasive species across the U.S. and Canada. EDDMapS cooperates with and aggregates data from other invasive species mapping projects such as GLEDN (Great Lakes Early Detection Network) and

NAISN Launches New Informational Website

NAISN Launches New Informational Website – 

The North American Invasive Species Network (NAISN) has launched a new informational website (, which provides a wide variety of invasive species management and research resources, links to a multitude of potential partner organizations, and access to streamlined data-sharing platforms for users throughout the USA, Canada, and Mexico. 

NAISN website development and design was undertaken by three of the eight NAISN member hubs: the Center for Invasive Species Management, Montana State University; the Center for Invasive Species and Ecosystem Health, University of Georgia; and the Center for Aquatic and Invasive Plants, University of Florida

NAISN is an American 501(c)3 non-profit, science-based organization that was formed in 2010 by university and government scientists and invasive species specialists from across North America. Mexico and Canada participate as NAISN members through a Memorandum of Understanding. 

Because invasive species cross governmental jurisdictional boundaries, NAISN aims to unify and connect existing regional invasive species management and prevention efforts into a single network to improve communication, collaboration, and overall coordination in North America. Its overall goal is to enhance multi-jurisdictional responses to biological invasions across the continent. NAISN membership is targeted toward regional university centers and institutes, government institutions, non-profit organizations, research labs, and/or other groups and individuals with invasive species interests and qualifications that are valuable to the mission of NAISN. 

In addition to serving as a North American focal point for invasive species management, policy, outreach, and research information, the NAISN website also (1) showcases the NAISN organization and the services it offers; (2) provides direct links to the Global Invasive Species Information Network (GISIN) and the Early Detection and Distribution Mapping System (EDDMapS) database systems—platforms for viewing existing and uploading new invasive species data; and (3) provides a compendium of North American invasive species organizations.

We encourage you to visit, share your work and data, and consider joining NAISN as a member. Feel free to email suggestions or feedback to

Cogongrass Invades the South

It grows on every continent except Antarctica and has earned a reputation as one of the worst weeds on earth. Now, according to U.S. Forest Service emeritus scientist Jim Miller, cogongrass (Imperata cylindrica) is one of the most threatening invasive species in the South.

Worldwide Cooperation Fighting Invasive Species

Center Co-director, Dr. Keith Douce recently completed a trip to France and Switzerland where he met with and discussed ongoing programs and collaboration opportunities between The Center for Invasive Species and Ecosystem Health and:
  • The leadership of The European and Mediterranean Plant Pest Organization (EPPO);
  • Dr. Alain Roques and other members of The Forest Entomology Section of the National Institute for Agricultural Research (INRA), Station de Zoologie Forestière, Orléans, France;
  • Dr. Marc Kenis, Head of Forestry and Ornamental Pest Research, and other CABI project leaders and associates at the CABI Delemont, Switzerland station.
While in Europe Dr. Douce had a chance to review the newly released, Insects and Diseases Damaging Trees and Shrubs of Europe which was edited by Milan Zùbrik (Head of Department of Forest Protection and Game Management, National Forest Centre, Zvolen, Slovak Republic); Andrej Kunca (Head of Forest Protection Service, Forest Research Institute, Banská Štiavnica, Slovak Republic); and György Csòka (Head of Forest Research Institute, Department of Forest Protection, Mátrafüred, Hungary).

Prominent forest protection experts from across Europe joined together to create this book: a comprehensive atlas to the world of insects and diseases damaging trees and shrubs in Europe.

The book is easy to use and the pests are arranged by the tree species on which they occur.

Information about each pests include: scientific name; common English name; life cycle; description of the life stages; significance (importance in Central Europe); and known distribution.

The book is richly illustrated by over 4,300 unique colour photographs (many of which were taken by the editors themselves), showing more than 1,100 species of insects and diseases causing damage to tree species and shrubs in Europe. Many of these and other images have been shared with Bugwood Images by the photographers.

The green menace strikes again! Human health effects of Emerald Ash Borer

Steven Valley, Oregon Department of Agriculture,

PBS NewsHour just published a piece on How Removing Trees Can Kill You as related to the loss of ash in Detroit, Michigan as a result of Emerald Ash Borer. 

Geoffrey Donovan noted "Increased rates of death from cardiovascular and lower respiratory mortality in the counties with emerald ash borer. And interestingly, what we found was the effect got bigger the longer you had an infestation, which makes sense because it takes two to five years for a tree to die typically."

I've always touted the fact that trees in urban environments make it a better place to live. It takes something like this to make you appreciate just how important they can be!

Customs Inspectors - On the Front Lines

Dave Munday's recent article in The Post and Courier states, " The notorious big-headed ant was intercepted before it could gnaw its way through the Lowcountry.
The ants, along with a bunch of other insects, were found April 30 in the port of Charleston, crawling around in a container of aluminum scrap metal on a ship from Costa Rica, according to Steve Switzer, spokesman for the local customs office.
The big-headed ant is listed among 100 of the “World’s Worst” invaders, he said. It not only threatens native plants and other insects, it’s known to chew on irrigation pipes, telephone cables and electrical wires.'"

Cogongrass in Georgia: Spring 2013 Update

Cogongrass in Georgia:
Spring 2013 Update from the Georgia Forestry Commission
Cogongrass flowering(seed production) becoming visible.
First cogongrass spot detected in Turner County.

There have been 34 positive cogongrass detections thus far in 2013. Cogongrass has been detected in Turner County for the first time in 2013 bringing a total of 723 known cogongrass spots in Georgia scattered across 53 counties covering 189 acres. The status and treatment for each spot is at varying levels. The Georgia Forestry Commission (GFC) recognizes a spot as eradicated after three (3) consecutive years of finding no cogongrass resprouts. Presently, 224 spots have been eradicated, 137 spots have been negative for two years, 131 spots have been negative for 1 year while the remaining 228 spots are active. Overall, approximately 70% of all known spots are now negative for cogongrass. The GFC will continue making follow-up site inspections and herbicide treatments beginning in May and continuing through the summer and early fall. Any landowner with questions regarding the status of the cogongrass spot(s) on their property should contact their Regional Forest Health Specialist.

How do you identify cogongrass flowers?
Cogongrass shoots in Georgia are beginning to emerge. Therefore, it is time to begin looking for cogongrass in its flowering stage. The flowers are 2-8 inches in length; light, fluffy dandelion-like seeds that are white in color and cylindrical in shape. Flowering time is dependent on the local climate, but is usually present from late March through early June. The cool spring weather in 2013 delayed the beginning of flowering until mid April in much of South Georgia. The photos below show cogongrass flowering at its peak, dispersal period.
What are the top five cogongrass detecting counties in Georgia?

Decatur 163 sites
Seminole 82 sites
Early 65 sites
Grady 55 sites
Thomas 51 sites

Currently in 2013, cogongrass has been detected in 14 counties across south Georgia including: Baker, Brooks, Calhoun, Camden, Charlton, Colquitt, Decatur, Early, Grady, Mitchell, Seminole, Terrell, Thomas and Turner counties. Landowners are encouraged to inspect their property for cogongrass and report any new potential detections to the local Georgia Forestry Commission county office.
Cogongrass identification brochure and pocket ID available from the GFC:
Landowners are encouraged to spend time on their property searching for this invasive grass. Normally, cogongrass grows in circular patches. Identification brochures are available at your local Georgia Forestry Commission (GFC) county office. Personnel from your local GFC office can make a positive identification on reported cogongrass finds. The "Cogongrass in Georgia" video showing the key identification features can be viewed at:

Running Bamboo Invasive in Connecticut

James Moshier writing for the Bulletin posted this story about bamboo in Connecticut, "Terri Groff, a retired nurse who is field researcher for the Institute of Invasive Bamboo Research, gave a briefing to the Preston Board of Selectmen on Thursday, noting that she has located two species of running bamboo — Yellow Groove Bamboo and/or Running Timber Bamboo — at 11 locations in the town. Groff lives in Preston."
Caryn Rickel,Seymour founder of the Institute of Invasive Bamboo Research has been working hard to get regulations passed for the control of running bamboos. She has written papers and trained volunteers to gather and report data on these invasive plants to EDDMappS. There have been 168 reports of Phyllostachys aureosulcata in Connecticut alone with many other reports of species in the genus, Phyllostachys, being reports in several states.

Dr. Robert Eugene Eplee, Sr., Remembered

WHITEVILLE, NORTH CAROLINA, USA -- Dr. Robert (Bob) Eugene Eplee Sr., 79, passed away on Wednesday, Jan. 30, 2013, at the New Hanover Regional Medical Center in Wilmington, North Carolina.

Bob is best known and remembered for his research on the biology and control of Witchweed [(Striga asiatica (L.) Kuntze], a parasitic weed that is native to Africa and Asia, that was first discovered in southeastern North Carolina, in July, 1956. Thanks in large part to his 30 year research program to develop methods and equipment for the USDA-Carolinas Witchweed Eradication Program, the infestation has been reduced from 432,000 acres in the North and South Carolina Coastal Plain (1970) to 1,542 acres (end of 2012).

The principles and practices he developed in the Witchweed Program also contributed greatly to the development of new approaches for invasive species prevention in the U.S. and elsewhere. Some examples include:
  • Weed Science Society of America Liaison for Passage of the Federal Noxious Weeds Act of 1974
  • Science and Technical Support for Federal-State Weed Eradication Programs (e.g., Goatsrue in Utah, Common Crupina in Idaho, Hydrilla in California and Florida, and Japanese Dodder in South Carolina – 1981-2000)
  • Original member - U.S. Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) (1990)
  • Development of Interagency Approaches for Early Detection and Rapid Response to New and Emerging Invasive Plants through State Invasive Species Councils and Committees (e.g., Wyoming Weed Team – 1998) and Invasive Plant Task Forces (North Carolina Giant Salvinia Task Force - 2002)

Disease Deadly to Bats Confirmed in Georgia


ATLANTA (March 12, 2013) – The disease that has killed millions of bats in the eastern U.S. has been confirmed for the first time in Georgia.
The Georgia Department of Natural Resources, the National Park Service and the U.S. Fish and Wildlife Service announced today that bats with white-nose syndrome were found recently at two caves in Dade County.
A National Park Service biologist and volunteers discovered about 15 tri-colored bats with visible white-nose symptoms in a Lookout Mountain Cave at Chickamauga and Chattanooga National Military Park in late February. On March 5, a group led by a Georgia DNR biologist also found tri-colored bats with visible symptoms in Sittons Cave at Cloudland Canyon State Park.
A bat from each northwest Georgia site was sent to the Southeastern Cooperative Wildlife Disease Study in Athens. Histopathology confirmed both bats had white-nose syndrome.
The name describes a white fungus,
Geomyces destructans, often found on the muzzles, ears and wings of infected bats. White-nose, or WNS, spreads mainly through bat-to-bat contact. There is no evidence it infects humans or other animals. But spores may be carried cave-to-cave by people on clothing or gear.

Tree Health and Human Health Linked

From an article by the USDA Forest service: "Evidence is increasing from multiple scientific fields that exposure to the natural environment can improve human health. In a new study by the U.S. Forest Service, the presence of trees was associated with human health.
For Geoffrey Donovan, a research forester at the Forest Service’s Pacific Northwest Research Station, and his colleagues, the loss of 100 million trees in the eastern and midwestern United States was an unprecedented opportunity to study the impact of a major change in the natural environment on human health."
