Download Guidebook on Management of Invasive Plants & Pests of Illinois

by Tina Casagrand

A comprehensive guidebook on Management of Invasive Plants & Pests of Illinois is now available online as a free download:

The book includes clear and direct recommendations for management of ubiquitous and emerging invasive species, including Japanese Hops, Tree of Heaven, Multiflora Rose and many, many more!

Though the guide is for Illinois, the vast majority of these species occur in our region.  As to specific control recommendations, the authors use precise language and clear instruction (clearly stating percentages as v/v as opposed to % active ingredient, clearly differentiating between triclopyr ester and triclopyr amine, etc).

A phenology calendar is available in a special pull-out section.

We are grateful to SIU-Carbondale, Morton Arboretum and University of Illinois Extension for creating this fabulous resource!

Mizzou Botanic Garden Cuts Down Pear Tree & Takes the Pledge to Stop the Spread of Invasive Plants

The Missouri Invasive Plant Task Force, a resource of the Grow Native! program, invites communities, campuses, businesses and other entities to follow Mizzou Botanic Garden’s example and take the pledge to control the spread invasive species on their property.

Jefferson City, MO (September 28, 2018)—This morning, the first of eight Callery pear trees on the Columbia campus of the University of Missouri was cut down—not by vandals, but by university officials. During the invasive plant awareness and educational event, officials not only removed the invasive, non-native tree, but also signed a pledge signaling the Mizzou Botanic Garden’s continued commitment to control other invasive plant species on campus. The remaining seven trees will be removed the week of Oct. 1, 2018.

            “These pear trees, located in the College of Agriculture, Food and Natural Resources (CAFNR) courtyard, were planted in 1998 as part of the landscaping for the new Anheuser-Busch Natural Resources Building for their profusion of spring blossoms and brilliant fall foliage,” said Pete Millier, Director of Mizzou Botanic Garden, a designation for the campus. “Now, however, we know better,” said Millier, “and the Mizzou Botanic Garden is committed to stopping the spread of this pretty but highly invasive tree and other non-native invasive plants that threaten native biodiversity and are problematic for farmers and other landowners. We are proud to have taken this step, and to be the first entity in the state to have signed the Missouri Invasive Plant Task Force pledge to stop the spread of invasive species.” For more than two years, Mizzou Botanic Garden has carried out other invasive plant projects, including the removal of five Callery pear trees at the Memorial Union, replacing them with non-invasive trees, and the organization of a mass bush honeysuckle/winter creeper removal along a portion of Flat Branch Creek.

“Mizzou Botanic Garden is to be commended for publicly demonstrating its dedicated effort to stopping the spread of invasive plants,” said Carol Davit, Executive Director of the Missouri Prairie Foundation, the nonprofit conservation organization and land trust that operates the Grow Native! program, and serves as Chair of the program’s Missouri Invasive Plant Task Force (MoIP), a multi-disciplinary, multi-agency group working as a united front to foster greater statewide early detection and control of invasive plants. “We invite other educational institutions, corporate campuses, municipalities, neighborhood associations, and other entities to take the pledge as well to signal their commitment to joining the fight to control invasive plants and mitigate the serious threats they pose.”

MoIP Task Force members developed the pledge with a number of benefits in mind. First, it lets the stakeholders of a campus, business, community, or other entity who may be concerned with invasive plants on that property know that the entity, by taking the pledge, has committed to developing a plan and dedicating resources to the control of invasive plant species. Second, it helps stakeholders understand that controlling invasive plants on that property will take time. Additionally, when a community or other entity lets its stakeholders know it has signed the pledge, it provides an opportunity for stakeholders to get involved in the effort.

“Invasive plants are serious threats to Missouri’s native ecosystems, as well as many native plants and animals, the built environment, and many facets of the state’s economy, including cattle production, the timber industry, and many aspects of outdoor recreation, including fishing and hunting industries,” said Davit. “Missouri will control invasive species only with the concerted efforts of many entities, including private citizens working together. Our state is a long-time, nationwide leader in natural resource conservation, and by leading in invasive plant control as well, we can further safeguard Missouri’s habitats, fish, wildlife, and other cherished aspects of our natural heritage.”

            Entities wishing to sign the pledge may do so via a Google form available at www.moinvasives.org. The Missouri Invasive Plant Task Force (MoIP) can also provide a pledge document suitable for signing ceremonies and framing. Many resources on the identification and control of invasive plants, including native alternatives to invasive plants, are available from MoIP as well.

2nd Annual Invasive Species Day at Missouri State Fair 2018

by MoIP 0 Comments

The Missouri Invasive Plant Task Force (MoIP) had a great time at the MO State Fair on Friday, August 10! We were thrilled to be among other important organizations participating in last week’s invasive species collaboration/education event. Thank you to the steady stream of people who came to learn about invasive species causing economic or environmental harm in Missouri.

This Facebook Live video by MDC is a tad choppy, but it captures the essence of the collaboration!

Invasive weeds will no longer have “the right of way” for over 700 miles of southeast Missouri roads.

CAPE GIRARDEAU, Mo. – The Missouri Department of Conservation (MDC), Missouri Department of Transportation (MoDOT), and the Missouri Prairie Foundation (MPF) have partnered to work with contractors to eliminate invasive plants along roadways from the top of Ste. Genevieve County, all the way to the southern border of Missouri. According to Nate Muenks, MDC’s habitat management coordinator, 723 miles of roadways will be spot treated for invasive plants, in a phased approach.

“MDC is thrilled to partner with MoDOT, MPF and the contractors to take this proactive approach against the threat of invasive plants,” Muenks said. “When invasive plants are left to thrive, they choke out native plants. The reduction in native plants can destroy valuable habitat and is very hard on our wildlife populations.”

Of the 723 miles of highway that will be spot treated for invasive plants, 165 miles are along Interstate 55. The other 558 miles are along roadways connecting to the Interstate, all near or in Conservation Opportunity Areas (COA). COAs are geographical areas where broad conservation goals are best met. MDC, with the help of conservation partners, identifies COAs throughout the state where investments in the prioritized areas can increase the likelihood of long-term success, maximize effectiveness over large landscapes, improve funding efficiency and promote cooperative efforts with other agencies for benefits that cross property lines.

Muenks said MDC, MoDOT, MPF and the contractors all see the value in working together to combat the prolific spread of invasive plants.

“Our roadways are a major traveling corridor, for not only public transportation but also in the spread of invasive weeds,” said Mark Aufdenberg, a MoDOT roadside manager. “It’s surprising how invasive seeds are spread through vehicle movement, so if we can treat our roadways and stop them before they go onto other properties and conservation areas, that’s a good thing.”

Aufdenberg said the cooperative project supplements MoDOT roadside management and allows MoDOT employees to focus more time on maintaining roadway surfaces and safety.

“Having the help from contractors and other agencies is a big benefit to us,” Aufdenberg said. “We don’t want to give invasive weeds the right of way.”

Aufdenberg said the contractors will not broadcast spray herbicides across the entire roadsides, but will instead spot-spray, targeting only the invasive plants.

“This targeted, specific approach will protect the good plants, while targeting the bad,” he said.

MPF agrees that the state’s roadways provide connectivity across the state, and not just for people. The MPF is a private, nonprofit, conservation organization with a mission to protect and restore prairies and other native grasslands, some of the most biologically diverse habitats in the state.

“We’re very concerned with the control of invasive species on the property we own and we’re very pleased to work in partnership with MDC, MoDOT and the other entities involved in this project,” said Carol Davit, MPF’s executive director. “Invasive plants pose real environmental and economic threats to our state, and collaboration is key in this fight.”

Davit said the project is also important because the work is happening in highly trafficked areas.

“Because this work is very visible along the roadways, we hope to inspire Missourians, and travelers in general, to be vigilant and take action against invasive plants on their own property as well,” Davit said.

Aufdenberg asks drivers in southeast Missouri to watch out for the contractors as they work along the roadways. Drivers will see large, orange, diamond shaped signs that say, “Invasive Plant Strike Team” where workers are spraying.

“Please slow down and give them some room as they work,” Aufdenberg said. “Safety is most important in our roadside projects.”

Muenks said MDC can help private landowners who want to eliminate invasive plants and improve wildlife habitat on their land. More information for landowners is available atwww.mdc.mo.gov/property.

Drivers will see work along 723 miles of roadways as Missouri’s cooperative Invasive Species Strike Team works to spot treat invasive plants. This proactive approach will protect the good plants while targeting the ones that don’t belong in the region. (MDC photo)

Requiem for a Bradford Pear

This shows where the Bradford pear limb broke off from the trunk and apparently other limbs broke from the same area previously. South St. Louis, 2017.

I had inherited my much longed for older sister’s bedroom.  It was a garret-like space that opened into our dusty, but neatly arranged attic with oversized attic fan serving as both focal point and cooling system in the early 1960’s. Here too, was the board where my chalk smudged seven-year-old fingers laid out my future farm.  Lots of horses with paddocks to the west of the house and long southern pastures in the fore were carefully drawn.  The front drive would, of course, be Bradford pears lined up two-by-two all the way to the street.

I was raised on a love of Bradford pears.  Originally sent from China to Europe, their snowy spring dresses came to adorn landscapes in all the most fashionable business parks beginning in the ‘50s.  As subdivisions became popular, so too were these orderly, oval-topped sentries planted throughout neighborhood entries and parks alike.  Their march toward omnipresence had begun.  

As time passed, years of dust settled on the chalkboard with the drawing of my farm.  Bradford pears advanced their hold on whole communities as I was building a career and raising a family.  No horticulturalist, I had not studied the darker side of the pernicious pear.  As I grew, those first pears started to disintegrate in storms.  “Break-away” pears we labeled them as we began to recognize they were neither strong nor long-lived, have lives of usually less than 25 years, with their demise commonly arriving after only 15 to 20 years.

Then, Douglas Tallamy added a tombstone for all of the cultivars of the Callery pear including the Bradford, Cleveland and handful of others.  His studies revealed how poor these trees are in hosting food sources for birds and other wildlife. In a talk for the Missouri Prairie Foundation, Tallamy discussed computations that a single family of chickadee babies will devour 9,000 caterpillars on their way to adulthood.  Those caterpillars like oak trees and other natives – Bradford pears, not so much.

As I wrote this article I contemplated the double row of Cleveland pears the former owners planted on my farm with a rueful smile.  They have fire blight and all must be removed.  I cannot blame myself or you for all the lacy ladies, those Bradford pears planted across our country.  We only went where we were led.  But I can pledge a new allegiance to serviceberry, redbuds and other native trees for beauty along my drive and food in the bellies of birds.  And when a grandchild uses my old chalkboard, I’ll teach them well about the shallow pleasures of a pretty face or flower alone.  Our landscape’s beauty is made of more substantial stuff.
