Finds One-Time Herbicide Use Decreased Native Plants, May Have
Increased Invasive Plants (Sep 29, 2009)
Montana State University.
A new study shows that the application of a herbicide on the invasive weed leafy
spurge 16 years ago had reduced the level of native wildflowers -- including
Missouri goldenrod and yarrow and the targeted invasive weed (leafy spurge) had
potentially increased. The study Control
Effort Exacerbates Invasive-Species Problem is published in Ecological
Applications (Jan 2009).
the Country, Invasive Pest Species Are Causing Problems (Sep
National Pest Management Association.
Conservative estimates by the Smithsonian Institution put the number of known
insect species found in the United States at more than 91,000 – not including
an additional 73,000 unidentified species. These numbers are likely to climb
as increased international travel and shipping provide a means for foreign insects
(invasive species), to more easily infiltrate the country. The National Pest
Management Association urges vigilance against invasive species.
Species on the March: Variable Rates of Spread Set Current Limits
to Predictability (Sep 17, 2009)
National Science Foundation.
In a paper published in this week's issue of the journal Science (see abstract;
full access requires subscription), biologists report a previously unknown
high variability in the rates of invasive species spread. Although more
research is needed, the uncertainty the biologists found may place more
species at risk in a changing climate: flora and fauna may not be able
to march one step ahead of the pace of global warming.
Hurricane Havoc: Environmental Teams Tackle the
Invasive Plants and Weeds that Impede Flood Control During Massive
Storms (Sep 14, 2009)
Weed Science Society of America.
If left unmanaged, invasive plants can promote flooding by jamming pumps and
blocking water flow, following a massive storm. Environmental officials are using
routine maintenance controls to prevent reoccurrence of the species, which include water
hyacinth, water lettuce, hydrilla,
and other fast-growing water plants.
Light Brown Apple Moth for Eradication, Quarantine Is Justifiable
In Draft Response by APHIS to Petitioners (Sep 14,
National Academy of Sciences.
A new report from the National Research Council finds that the U.S. Department
of Agriculture's Animal and Plant Health Inspection Service is within its broad
regulatory authority to classify California's invasive Light Brown Apple Moth
as an "actionable" pest, which the agency asserted in a draft response
document to two petitions questioning the classification.
of Irish potato famine pathogen decoded (Sep 9, 2009)
A large international research team has decoded the genome of the notorious organism
that triggered the Irish potato famine in the mid-19th century and now threatens
this season's tomato and potato crops across much of the U.S. Phytophthora
infestans, also known as the late blight pathogen,
remains a major threat to world food security. This sequencing is a major breakthrough
that will accelerate the design of more sustainable control strategies to combat
one of the most challenging pathogens threatening global food security.
Secretary Vilsack Announces Economic Recovery Projects for Forest
Health Protection: 78 Projects in 20 States and The District Of
Columbia Will Receive a Total Of $89 Million To Address Problems

Time, an Invasive Plant (Garlic Mustard) Loses its Toxic Edge (Sep
University of Illinois.
A new study on garlic mustard shows
that its primary weapon, a fungus killing toxin injected into the soil, becomes
less potent over time. The study, Evolutionary
Limits Ameliorate the Negative Impact of an Invasive Plant (2009; PDF | 1.3 MB),
in Proceedings of the National Academy of Sciences, is one of the first
to show that evolutionary forces can alter the attributes that give an invasive
plant its advantage. This study was funded by the Agriculture
and Food Research Initiative (ARFI) at the U.S. Department of Agriculture
and by the Illinois Department of Natural Resources.
Your Ports Against Invasive Species (Sep 1, 2009)
International Union for Conservation of Nature.
A new report Neighborhood
Watch: Early Detection and Rapid Response to Biological Invasion Along US Trade
Pathways (2009; PDF | 9.4 MB) says accidental introductions of pests and
pathogens threaten economic, environmental and public health. The report offers
recommendations to improve biosecurity measures at U.S. ports,
as well as a possible funding mechanism based upon the "polluter pays" principle.
Recommendations include improved coordination between agencies and greater international
cooperation. Neighborhood Watch follows an earlier volume "Denying
Entry: Opportunities to Build Capacity to Prevent the Introduction of Invasive
Species and Improve Biosecurity at U.S. Ports" (2007; PDF | 4.6 MB) which
addressed the challenges of "regulatory exclusion" of potentially invasive
species through trace pathways.
