Clean your boating equipment to prevent the spread of hydrilla

It is important that we clean our boating equipment to prevent the spread of invasives like hydrilla.

Garlic Mustard control on the Vinton Experiemental Forest

These past few weeks the AOWCP has been working with OSU-Extension and the USFS Northern Research Station to control garlic mustard at the Vinton Experimental Forest.


This garlic mustard has already been sprayed and has noticeable signs of stress.  Most plants will take several days to weeks to finally die.

This time of year is also a great time to spray garlic mustard seedlings that germinated this spring.

Invasive Phenology Update: Multiflora Rose, Canada Thistle, Poison Hemlock, and Chickweed

There are a lot of plants coming up, too many to document.  Here a few I found the other day.


Poison hemlock (Conium maculatum) – basal rosettes


multiflora rose (Rosa multiflora) – leaf out


Canada thistle (Cirsium arvense) – emergence


Chickweed (Stellaria media) – flowering

Invasive Phenology update- garlic mustard and stinking pennycress

Looks like Garlic mustard (Alliaria petiolata) as begun to bolt and has some developed buds.



Stinking pennycress (Thlapsi alliaceum) is flowering and seeding alongside roadways and open areas

Escaping Ornamentals…Is your garden spreading into the countryside?

Burning bush excaping

Burning bush excaping

We all want our yards to look nice and many of us enjoy planting and caring for the plants that enhance our landscapes. Gardeners do important work, but can be unknowing spreaders of some dangerous non-native invasive species. From bush honeysuckle, barberry, burningbush and ornamental grasses, gardeners are often responsible for the spread of these invasive species into Ohio’s natural areas.

Burningbush, or Euonymus alata is one of our most popular landscape shrubs. Burningbush is nicely shaped and attractive all year, but in the fall, it sparks to life with vibrant red foliage. This shrub’s color and because it seeds well and is easy to dig make it popular among gardeners.

But burningbush has a dark side. It is an invasive species; a non-native species whose introduction causes economic, human, and/or environmental harm. In the case of burningbush, it spreads out beyond our yards into the surrounding woods displacing native shrubs and tree seedlings. Once established, burningbush grows so densely that it out-competes most native plants. With native plants diminished, the wildlife suffers and the ecosystem starts to unravel.

Japanese barberry

Japanese barberry

Several other gardening favorites have the same bad habit of spreading into natural areas. These include bush honeysuckle, privet, Japanese barberry, autumn olive, and ornamental grasses like Miscanthus

Bush honeysuckles are prolific shrubs with fragrant spring flowers and red fall berries. They blanket roadsides, waste areas, and many wooded yards and parks. Japanese barberry is a small shrub with purplish foliage and small thorns, tending to grow in shady woodland sites. Autumn olive is a large shrub that can reach 15 feet and infiltrates woodland edges. Ornamental grasses create thick mats in waste areas and prairies and create fire hazards.

Some might question the damage that invasive species cause. Green is good, right? But in nature not all plants are created equal. While these invasive species have berries that are eaten by wildlife, research shows that the nutrient content in honeysuckle and autumn olive fruit is inferior to native fruit like viburnum, Virginia creeper, sassafras, and spice bush. 

So if you have these invasive species in your garden, consider removing and replacing them with native plants. Several native shrubs have beautiful fall color, nice flowers, nutrient rich berries, and ecosystem benefits. These include Virginia sweetspire, smooth or fragrant sumac, nannyberry viburnum, arrowwood viburnum, blackhaw viburnum.

The good news is that invasive species are controllable. They typically pull out of the ground easily after a rain. Big ones can be cut down and their stumps treated with an approved herbicide. The best way to keep them from returning is to fill the spot with desirable vegetation. As with all things, it is easier to deal with them when they are small and few and far between as opposed to waiting until you have an infestation.

Training Webcast: New Schedule April 2


Apologies for the technical issues that prevented us from holding the Great Lakes Early Detection Network (GLEDN) Mapping Webcast on Tuesday as planned. We learned that the server at Purdue that runs Adobe Connect was down for about an hour, right at the time our webcast was scheduled. We should not have this same problem again, unless we have extraordinarily bad luck twice. Here’s to better luck next time.

We have rescheduled the webcast for April 2 at 11:00 Eastern/10:00 Central. The webcast will be recorded and posted on the MIPN website for those who are not able to listen in. I encourage you to attend the webcast if possible, though, because you will have the opportunity to ask questions about how to use GLEDN.

The meeting URL is below. Please contact Kate Howe if you have any questions.
