Corktree Early Detection and Rapid Response

Southern Illinois Weed Watch is working.
By: Sarah Calloway
Nancy Garwood, research professor at Southern Illinois University, identified several Amur corktree plants, Phellodendron amurense, on her property. Several were already mature and bearing fruit in the fall of 2008.
At a Southern Illinois Weed Watch training session in March of 2009, Nancy mentioned finding these trees to Chris Evans, River to River Cooperative Weed Management Area Coordinator. This species, while being listed as an invasive in other parts of the United States, had not previously been reported as present in southern Illinois. In early November 2009, Nancy updated Chris on new specimens she had found.
On November 5th, 2009, a site visit was made to check the cork trees. The following week, Nancy reported that she located more of these non-native trees on neighboring land, as well as several large specimens and many seedlings on the Shawnee National Forest. Chris and Nancy contacted the Forest to schedule a site visit to look at the trees.
In mid November, a site visit was made by Chris, Nancy and several Forest employees. Nancy had previously flagged and GPS'ed the cork trees on her property and those within the Forest. They decided to remove the cork trees by cutting them with a chainsaw or ax, and/or pulling the saplings and seedlings. The trees were removed at the beginning of December, 2009, by Shawnee National Forest employees. The stumps of the cork trees will be monitored for re-sprouts and the area will be monitored to remove seedlings or saplings.
Amur corktree is a deciduous tree named for its thick, corky bark that has a distinctive bright yellow layer of inner bark. It does especially well in forests and wooded areas that have been exposed to human disturbance, where it forms dense stands and crowds out native species, including oaks and hickories. The Amur corktree has been reported as invasive in Illinois, New York, Pennsylvania, Virginia and Massachusetts (
The collaborative effort between the Shawnee National Forest and the River-to-River Cooperative Weed Management Area, developed over the past couple of years, has been highly beneficial not only to the Forest but to all of southern Illinois in protecting ecosystems across boundaries.

Six Million for Cogongrass in Alabama

AFC Announces Key Strategies to Fight Cogongrass Using Federal Stimulus Grant
As announced earlier in the spring, the Alabama Forestry Commission (AFC) was awarded a $6.3 million grant to embark on a cogongrass control program in Alabama. Although this funding provided through a 2009 American Recovery and Reinvestment Act (ARRA) Grant will enable the AFC and its partners to initiate a proactive, coordinated campaign to combat cogongrass, it will not begin to cover the expected costs to eradicate the noxious weed from Alabama. Considering the extensive number of acres already infested, it is estimated that costs would exceed $50,000,000 to minimize the threat of cogongrass throughout the state. In regard to the grant, State Forester Linda Casey said, “Ultimately, we wish to completely eradicate this nuisance, as well as all other non-native invasive species. However, with the welcomed but limited funding provided, it will be impossible to make a significant impact for all landowners where cogongrass is widespread and in the counties where this invasive plant has been allowed to grow virtually unchecked since 1912. All interested citizens need to be aware of this reality. We believe it is possible to convince our state and federal elected officials, as well as the US Forest Service, that given the appropriate funding, we can win the war against cogongrass. This current funding does indeed provide a start, but that is it all it can be.” The following broad strategies have been outlined by the Commission for the campaign against cogongrass: (1) Define a geographic region of the state where cogongrass can and will be eradicated once it has been detected and precisely mapped; (2) Allocate resources such that strategic buffer zones can be established to keep the weed from moving back into areas that are free of cogongrass; (3) Begin a statistically valid detection and mapping program in the most heavily infested areas, so that informed decisions can be made as to how to eradicate the plant across the state; (4) Finally, do everything possible to secure additional funding during this three-year program, such that a full-scale detection and eradication program can be initiated. To begin the first proactive large-scale control of cogongrass in Alabama, Casey announced that the AFC has contracted with the forest management firm of Larson & McGowin, Inc. to provide the critical role of Project Coordinator. Said Casey, “Larson & McGowin’s reputation as a leader in forest management and consulting throughout the South, as well as the fact that the company is Alabama-based, made it a solid choice.” Larson & McGowin, Inc. is a full-service forest management and consulting firm headquartered in Mobile. The company was founded in 1957 and has branch offices in Greenville and Birmingham, Alabama, as well Arkansas, Georgia, Louisiana, and Texas. The firm has decades of experience providing property management services to small and large ownerships. Consulting and large scale project management experience includes forest inventory, appraisal, technical mapping, and analysis. Though focused on the southern United States, the firm has experience in other regions including U.S. Northeast, Pacific Northwest, Canada, Central America, and South America. Its subsidiary, Silvics Solutions, offers natural resource focused software and information technology services. Barrett McCall, RF/ACF and President of Larson & McGowin: “Alabama is a world leader in forest management as a result of decades of cooperative efforts between landowners, the Alabama Forestry Commission, and forestry professionals across the state. Tackling the complex management problems posed by invasive species such as cogongrass is important for us to continue this history of excellence. This grant gives us a much needed boost in these troubled economic times to get started. I am confident our forestry community is up to the challenge and our team at Larson & McGowin very much appreciates the opportunity to be of service in the war on cogongrass.” A website ( has been established to facilitate communication with Larson & McGowin. The website will be updated regularly as the program develops. For further information, contact Ernest Lovett, Project Coordinator, at (334) 240-9348 ( or Stephen Pecot, Communications Director, at Vendors and applicators should submit their contact information to or fax to (334) 240-9388, Attn: Cogongrass Program.

Expanded Programs to Eliminate Pythons from Everglades

Secretary Salazar Announces Renewed Commitment, Expanded Programs to Eliminate Pythons from Everglades

WASHINGTON, D.C. - Secretary of the Interior Ken Salazar today announced today that the National Park Service and U.S. Fish and Wildlife Service, in partnership with the State of Florida and other stakeholders, are renewing their commitment and expanding existing programs to eliminate Burmese pythons from the Everglades.

"Burmese pythons are an invasive species that have no place in the Everglades and threaten its delicate ecosystem," Salazar said. "We are committed to aggressively combating this threat, including having trained and well-supervised volunteers hunt down and remove snakes."

"I have also directed my staff to look at the possibility of allocating additional federal resources this fiscal year and I have asked federal and state agencies to work with us to quickly develop an action plan to control this invasive species," he said.

The Burmese python (Python molurus), a large exotic snake, is well-established in the Everglades. Everglades National Park, Big Cypress National Preserve, and the Water Conservation Areas, represent the core areas of the python infestation.

As effective predators, pythons are having negative impacts on native species in the Everglades ecosystem. Because of the serious threat posed by pythons, the National Park Service (NPS), Fish and Wildlife Service (FWS), and U.S. Geological Survey (USGS), along with the Florida Fish and Wildlife Conservation Commission, the South Florida Water Management District, and many other partners are actively engaged in a large variety of potential python control efforts.

Pythons are cryptic animals - they blend into their environments extremely well - making them difficult to efficiently locate and capture. Most python sightings and captures occur in developed areas, such as roads and canal levees, which comprise only a small percentage of potential python habitats.

Pythons have been observed within the largely inaccessible and remote mangrove forests of the parks. Conservatively, scientists believe that only small fractions (0.1-5%) of pythons present on NPS lands are detected. Given these challenges, the National Park Service and Fish and Wildlife Service have recognized the need to consider and implement a comprehensive, multi-pronged approach to python control. These efforts include:

Expansion of an authorized agent python capture program - For several years, NPS has partnered with up to a dozen experienced and highly motivated volunteer authorized agents that have removed hundreds of pythons. Data from these captures has been invaluable to park biologists in developing other control tools and assessing impact this invasive snake is having on native resources. The NPS is working on expanding the authorized agent program to provide more thorough and regular efforts to remove pythons. The Park Service is also working closely with the Florida Fish and Wildlife Conservation Commission to evaluate the State's pilot bounty permit system and consider its appropriateness for NPS lands.

Pilot "Partner with Hunters" Program in Big Cypress National Preserve - The NPS and Florida Fish and Wildlife Conservation Commission are working together to partner with licensed hunters that hunt game species within the Preserve under Florida state law. The "Partner with Hunters" program will allow trained, qualified, and licensed hunters the opportunity to terminate pythons, a non-game species, with the use of their firearm if they come across one during the course of their normal hunting activity. The snakes will be collected by the NPS and data gathered will be used for research/ monitoring and control efforts. Existing hunting activities and supporting infrastructure, including law enforcement, hunting check stations, and use of off-road vehicles, makes the Preserve an appropriate location for piloting this program in partnership with the hunting community.

Everglades invasive animal response team - NPS is actively working with FWS and USGS to establish a Federally-funded invasive animal rapid response and control team that would provide full-time coordination among the south Florida natural resource management agencies, including field operations, science support, and educational and outreach efforts.

Cooperative workshops - FWS has organized and facilitated multi-agency workshops to address the threats posed by pythons and help prioritize and coordinate management efforts. NPS and FWS provide leadership to the Everglades Cooperative Invasive Species Management Area, a multi-agency team, to better coordinate and pool resources.

Risk Assessment and review of control methods - FWS and NPS are funding a USGS risk assessment project to help define the nature of the threat and develop biological/management profiles for nine large constrictor snakes. The risk assessment will contain information that has broad application to the management of pythons and other large exotic constrictors in the U.S.

Study of python movements and habitat use - NPS is working with USGS, University of Florida, and Davidson College to understand python movement and habitat use in the Everglades. These efforts, including radio tracking snakes to allow scientists to follow them, often finding other snakes, and providing critical information to formulate effective control programs.

Python trap and attractant development - NPS and FWS are funding development of an effective python trap and lure along with USGS, University of Florida, and the U.S. Department of Agriculture. In addition, NPS is cooperating with an NGO to conduct preliminary research on python pheromones which may someday be used as an attractant for trapping. Prototype traps are deployed in North Key Largo in hopes of halting the spread of pythons to the Florida Keys and traps will soon be deployed in known python concentrations around Everglades National Park.

Unmanned aerial vehicles and thermal imaging - NPS is working with USGS and the University of Florida to test small, remotely operated airplanes and heat-detecting sensors for use in detecting pythons in the Everglades. These technologies may be useful to detect and aid in the capture of pythons in their natural habitats.

Diet Studies - NPS, in conjunction with the University of Florida and the Smithsonian Institution, is analyzing gut contents of captured pythons and identifying prey items to better understand the python's impacts on native species.

Mercury bioaccumulation studies - NPS has partnered with USGS to understand mercury concentrations in python tissue because high mercury concentrations may pose a risk to human health if pythons are consumed. This information is critical to inform the current development of python collecting and hunting programs.

Reporting mechanisms - NPS established a python hotline for public reporting of python observations.

Education and outreach - NPS and FWS have worked cooperatively with our partners at the Fish and Wildlife Conservation Commission and the South Florida Water Management District to develop signs that remind the public that release of snakes and other exotics is a crime. We have implemented the "Don't Let It Loose" public and school education campaign and endorsed Habitatitude to promote responsible pet ownership. NPS recently printed and distributed over 450,000 copies of "Florida Invaders" to educate the public about the threat of invasive nonnative plants and animals. The FWS and NPS participated in the recent State-sponsored Non-native Pet Amnesty Day event held at the Miami Zoo educating the public about pythons and other non-native invasive wildlife.

"The removal of invasive pythons from the Everglades in a key step in our larger ecosystem restoration efforts," said Dan Kimball, superintendent, Everglades National Park. "Our success will fully depend on how well we can cooperate, partner, learn from each other, and maintain a high level of commitment to addressing this problem in the long term."

"Eliminating these exotic pythons in Florida will require a full partnership between federal and state agencies and with the assistance from trained members of the public," said Pedro Ramos, superintendent, Big Cypress National Preserve. "These joint efforts will provide vital information on the animals' movement, habitat use, food sources and other information which will aid in future improvements of eradication methods."

"Addressing the python threat requires a broad partnership with many strategies," said Paul Souza, South Florida Ecological Services field supervisor for the U.S. Fish and Wildlife Service. "There is no one silver bullet. We are committed to continuing our work with our partners in the State of Florida to make headway on this
significant challenge."

Together, the NPS, FWS, and their partners will continue their efforts to implement a variety of python management efforts to control and hopefully eradicate the Burmese python in south Florida.

Support for the enemy-release hypothesis of invasive species

A very interesting article has come out on black cherry and why it is more aggressive in Europe than the US. Apparently it is because the US has a more virulent strain of soil fungus that keeps them in check. This seems to support the enemy-release hypothesis of invasive species.

Florida Cogongrass Cost-Share Program

Florida Agriculture and Consumer Services Commissioner Charles H. Bronson announced today that the department’s Division of Forestry will offer a pilot Cogongrass Treatment Cost Share Program to eligible non-industrial private landowners in several north Florida counties beginning next week.
The initial focus of the program is to impede the spread of cogongrass (Imperata cylindrica), one of the world’s worst weeds, from Florida into Georgia. Therefore the nine counties sharing borders with Georgia - Baker, Columbia, Gadsden, Hamilton, Jackson, Jefferson, Leon, Madison, and Nassau - will be the first priority. If funding allows, the program may be expanded to include Wakulla, Suwannee, Union, Washington, Calhoun, Liberty, Clay, Duval, Bradford, Holmes and Taylor counties.

Soybean Rust and Kudzu: An invasive species tag team

For the first time, soybean rust (Phakopsora pachyrhizi) has been documented as overwintering on kudzu (Pueraria montana) without any break in detection in Alabama, Georgia and Louisiana. Scientists are still exploring what the full effect of this may be, but it is possible for infected kudzu in these areas to act as a primary source for the disease.

For more information, take a look at the full story in The Gleaner. For the latest information on the distribution and spread of soybean rust, see the Soybean Rust ipmPIPE.

New Diagnostic Book for Insects and Diseases of Woody Landscape Plants

There is yet another book coming out on woody ornamentals. Mary Kay Malinoski and David Clement at the University of Maryland have written a diagnostic field guide on broad leaved woody ornamentals coming out in March. It is based in part on the Maryland plant diagnostic web site and has color keys to symptoms and causes of problems. Here is a link to get more information.

It was primarily geared toward the northeast region, but may work for other regions. They worked really hard to make this thing practical and useful for just about everyone. Eventually, they plan to put out companion field guides on needled evergreens and herbaceous ornamentals. If you have any questions, feel free to contact David Clement.

Tennessee Invasive Weed Awareness Week

Tennessee Invasive Weed Awareness Week

Governor Phil Bredesen has issued a state proclamation declaring Feb. 22-28, 2009, as Invasive Weed Awareness Week (IWAW) in Tennessee in conjunction with the 10th Annual National IWAW in Washington, D.C. The Tennessee Exotic Pest Plant Council (TN-EPPC), an all-volunteer, nonprofit organization, is working closely with various local, state and federal organizations and agencies to promote public education on the harmful impacts of nonnative, invasive plant species through several ‘pest plant removal events’ around the state. Events are planned in Memphis, Jackson, Nashville, Murfreesboro, Chattanooga, Knoxville, and Great Smoky Mountains National Park. (Details on separate page.) We are pleased to acknowledge our list of supporting groups and organizations in this statewide education effort. (See separate list.) Several of these supporters have organized a plant pull in their area and have invited local citizens to participate.

Throughout both urban and rural areas, invasive, non-native plants pose numerous threats to the Tennessee landscape, especially public lands such as parks and state natural areas. Invasive plant species overrun a variety of habitats, displace native plant populations, disrupt plant/animal associations, deprive wildlife of needed food sources, significantly reduce plant and wildlife diversity, imperil rare and endangered plants and animals, support nonnative pathogens and pests, and can alter ecosystem processes such as fire frequency/intensity, water and nutrient availability, soil chemistry and erosion. In addition, invasive plant species have a significant negative impact on agriculture and forestry. Nationally, costs associated with control as well as crop and land losses reach into the tens of billions of dollars annually. Gardeners, farmers, boaters, hikers, wildlife watchers, landscapers, hunters, anglers, landowners, and many businesses, all have a stake in recognizing and doing what they can to combat the most troublesome plant species.

TN-EPPC’s volunteer role is to monitor invasive species in the state, provide advice and counsel to local, state, and federal government entities as well as private land managers and landowners. Our Web site,, features a list of plants exhibiting invasive behavior in Tennessee, along with information on the best control methods and alternative native plant species for landscaping. A board of directors meets quarterly to identify and develop invasion response protocols, important partnerships, and education and outreach opportunities.

National Invasive Weed Awareness Week, now in its tenth year, features events focused on educating our federal policy makers and elected officials about the environmental and economic losses caused by invasive weeds. State, regional, and national invasive plant organizations across the country participate. TN-EPPC sends a representative each year.

Top Five Invasive Plants Threatening Southern Forests in 2009

Scientist Names Top Five Invasive Plants Threatening Southern Forests in 2009

New Maps Show Spread of Nonnative Plants across Southeast

Asheville,NC -- U.S. Forest Service Southern Research Station (SRS) Ecologist Jim Miller, Ph.D., one of the foremost authorities on nonnative plants in the South, today identified the invasive plant species he believes pose the biggest threats to southern forest ecosystems in 2009.

"Cogongrass, tallowtree, and Japanese climbing fern are among the fastest moving and most destructive nonnative plant species facing many southern landowners this year," said Miller. "Rounding out the top five invasive species that I’m very concerned about would be tree-of-heaven and nonnative privets. While our forests are besieged by numerous invasive plants, these and other nonnative species present serious financial and ecological threats to the South and its forests in 2009."

Nonnative species often out-compete native forest plants and may degrade forest productivity, wildlife habitat, recreational values, and water quality. Invasive species also greatly increase expenses as public and private land managers work to combat their spread and deal with their effects (such as increased wildfire risk and severity).

Nonnative plants can be introduced and spread by wildlife or through other natural means. Humans also spread invasive species by planting them in their gardens and yards and by seeds hitchhiking on their clothes. Additionally, tractors and mowers used in multiple locations without being cleaned often spread nonnative plants.

In an effort to inform forest managers, landowners, and others about where the most threatening invasive plants are in the South and to help them prepare for these threats, Miller collaborated with SRS Forest Inventory and Analysis (FIA) scientists to develop maps showing the spread, county-by-county, across the Southeast of more than 30 of the most serious nonnative plant species. The invasive plant data were collected on FIA plots throughout the southern United States in cooperation with State forestry agencies. In partnership with the University of Georgia’s Center for Invasive Species Science and Ecosystem Health, SRS researchers recently posted the maps and occupation levels online.

Maps posted at show the number of acres in a county covered by each nonnative species. Maps posted online at show the percent of subplots analyzed in a county that have each invasive species. A spreadsheet found at shows the total acreage of 33 invasive plant species in 12 Southeastern States (data for eastern Oklahoma is missing as SRS FIA just

completed this part of the State’s inventory this month). Users can access the maps and spreadsheet via Current plans are for researchers to update the information annually.

Miller hopes government agencies, forest managers, natural resource professionals, landowners, students, and others will use the information to help combat the spread of nonnative plant species in southern forest and grassland ecosystems.

Details on the five invasive plants mentioned above can be found online via: The Web page features Jim Miller’s book titled Nonnative Invasive Plants of Southern Forests: A Field Guide for Identification and Control, published in 2003. Request a copy by e-mail at or by calling 828-257-4830.

Based in Auburn, AL, Miller is a scientist in the SRS Insects, Diseases, and Invasive Plants of Southern Forests unit.

New Book - Economics of Forest Disturbances: Wildfires, Storms and Invasive Species

Book Breaks New Ground in the Study of Economics and Forest Threats Management

Asheville,NC -- U.S. Forest Service Southern Research Station (SRS) Director Jim Reaves today announced the publication of The Economics of Forest Disturbances: Wildfires, Storms, and Invasive Species . Edited by three SRS scientists, the book offers a synthesis of new approaches to understanding the economics of large-scale forest disturbances.

"This book comes at a critical time when America 's forests face increasing stress and damage from wildfire, pests, natural disturbances, and climate change - and when agencies face increasing demands for resources to tackle these threats," said Reaves. "I believe this book offers vital information that can assist decision makers and forest managers in developing strategies and making choices that will help them mitigate today's major stresses and ensure healthy forest ecosystems in the future."

The Economics of Forest Disturbances is the first book of its kind to present a comprehensive framework for analyzing the economic effects of large-scale catastrophic events such as wildfires, hurricanes, and invasions of non-native pests. With contributions from leading government and university scientists, the editors show how existing and new scientific techniques can be applied to identify the causes and consequences of forest disturbances. The editors emphasize that economic behavior matters, both in the production and mitigation of forest disturbances. Each chapter clarifies this general theme and shows how physical factors, such as climate, interact with economic factors, such as technology or management incentives, to produce economic damages. The book, which includes several case studies, resulted from the editors' belief that standard methods for evaluating economic impacts are often inadequate for addressing issues affecting forests and provide limited guidance for improved decision-making. The book's 19 chapters seek to describe the state-of-the-art in understanding the economic dimensions of forest disturbances.

The Economics of Forest Disturbances consists of four sections, which reflect the editors' view that: (1) economic analyses of forest disturbances go hand-in-hand with ecological understanding; (2) forest disturbances are random variables that are amenable to new statistical analysis; (3) consistent accounts of timber and non-timber economic impacts (such as disturbance effects on recreation or residential property values) are pre-requisite to planning and decision-making; and (4) economic models can be used to improve decisions and set priorities. The 422-page text is academically focused and written for forest economists, policy makers and analysts, land managers, graduate students, and others in the forestry arena.

Research Foresters Thomas Holmes, Ph.D., and Jeffrey Prestemon, Ph.D., and Research Economist Karen Lee Abt, Ph.D., compiled and edited the book. The scientists are part of the SRS Forest Economics and Policy unit based in Research Triangle Park , N.C. The book is published by Springer.
