Rock Bridge Memorial State Park is being threatened like never before by invasive plants and needs your help! If you haven’t considered doing invasive plant control volunteering before, the attachments will give you a good understanding of what’s involved. While we can’t spray this time of year, it does work to use cut/stump and pulling methods in winter as long as it’s above freezing and the ground isn’t frozen. It’s also a good time to give attention to some species/small projects that don’t get much attention during the growing season.
Attached are two planning docs that give details about locations/species/methods for work that needs to be done. The map shows locations of 3 spots along Clear Creek that need winter creeper pulled. This is an example of maps I can make as needed to help you find a particular location or I can take you out and show you a site that needs work. Notice the instructions doc. Please let me know what task you are willing to tackle and report when it’s done so I can keep this up to date and serve as a coordinator. If you can’t help directly, perhaps you can forward this on to others who can.
I want to thank those of you who have been working on invasive plant control. I’m estimating that we spot sprayed bush honeysuckle on about 300 acres in the Eastern part of the Gans Creek Wild Area this fall after natives lost their leaves! And our SPYC crew worked all summer with various species and methods. Having worked here for 25 years, I know of many locations that are in good shape today that would have become grown up in invasive plants except that we intervened on behalf of our native plants and animals. Let’s keep doing that!

Environmental groups blasted USDA’s Jan. 17 decision to deregulate a genetically engineered creeping bentgrass that has taken root in two Oregon counties.
In a joint news release, the Center for Biological Diversity and Center for Food Safety sharply criticized USDA’s decision to deregulate the grass, which was genetically modified to resist applications of glyphosate, the active ingredient in Monsanto Corp.’s Roundup weed killer.
Scotts Miracle-Gro Co. and Monsanto developed the grass for use mainly on golf courses. —Read the rest of the article.
A 12/8/2016 Capital Press Ag news article documented the decision to deregulate the genetically engineered glyphosate-resistant creeping bentgrass will be made by the USDA Secretary of Agriculture after the close of the final public comment period. Download the rest of the article.

The National Bobwhite Conservation Initiative (NBCI) has taken another significant step in the recovery of native vegetation and habitats on the landscape across the 25 NBCI states with the release of a new decision-making tool, NatiVeg, NBCI Director Don McKenzie announced today.
“With restoration of native grasses, wildflowers and shrubs across the landscape being a critical means to the recovery of bobwhite, grassland bird and pollinator populations, NBCI’s NatiVeg will make it significantly easier for landowners and resource managers to select the right native plants for their specific location and specific purpose,” said McKenzie.
NatiVeg (www.quailcount.org/NatiVeg) is a remote, Internet-based tool that works on desktops, laptops, tablets and mobile phones. Developed by NBCI and University of Tennessee Institute of Agriculture Information Technology Service and beta-tested by a variety of outside reviewers, NatiVeg is a database that, within the 25-state initiative’s range, delivers the proper native plant choices for a specific location and the user’s specific purposes, whether wildlife, forage, biomass, pollinators, critical area planting, restoration or soil conservation. That location can be specified either manually or by a connected mobile device’s GPS system. And the provided recommendations discriminate, for instance, between a big bluestem grass adapted to Texas and one adapted to Alabama based on location.
An eight-month project, NBCI first captured the database for the 126 Natural Resource Conservation Service’s (NRCS) Major Land Resource Areas (eco-regions) for the 25 NBCI states and secured the NRCS database of plant materials identified as suitable for conservation purposes. NBCI deleted from that list all non-native species, tree species and other species not applicable to the NBCI states, leaving only native grasses, shrubs, forbs and legumes in an eventual 306-species menu. NBCI then folded in a plant hardiness zone database into the mix. Also provided is a species “Location Assistance” button that delivers information from the respective state wildlife agency, including contact information for experts.
“There are still shortcomings to overcome,” McKenzie said. “For instance, there are many plants that NRCS has not done any work with, so are not included. In addition, there won’t be as many choices east of the Mississippi River because NRCS has worked more on western species. So, NatiVeg is a work in progress.
“We encourage landowners and resource managers to check out this new tool,” McKenzie said, “to help improve their native grassland restoration efforts, and we ask for feedback from users, to help NBCI continually improve this unique wildlife conservation service.”

LAWRENCE, Kansas – Research featured in the latest edition of the journal Invasive Plant Science and Management shows that the weed downy brome has developed fire-survival traits that are changing local growing conditions and making it impossible for native competitors to survive.
Downy brome has invaded millions of acres of arid grasslands in the western United States. As a winter annual, it finishes its life cycle by spring or early summer – several weeks before native grass species. The dried downy brome offers a large horizontal mass that can fuel frequent fires and help them quickly spread.
Researchers in the U.S. and Europe compared downy brome from the fire-prevalent U.S. Great Basin with populations of downy brome in Central Europe, where fires are rarely experienced. They discovered that U.S. populations of the weed produce seeds with a greater fire tolerance. The seedlings perform better in post-fire environments, produce more above-ground tissue and are more flammable than populations of downy brome in Central Europe.
“The increased flammability of downy brome in the U.S. and its greater aboveground plant mass promote earlier, more frequent fires of low intensity,” says Annamária Fenesi, a senior lecturer at Babeş-Bolyai University in Romania. “While downy brome thrives under those conditions, native species that have adapted to a much longer interval between fires are simply unable to recover. As a result, downy brome is able to thrive and spread, free of competition.”

An invitation from Eryn Maynard to do Citizen Science:
I lived in St. Louis for a couple of years doing invasive plant research at Washington University. I went on a few native plant walks with your WGNSS-Botany Group. It came up in conversation fairly regularly that invasive shrubs tend to leaf out earlier and keep their leaves later than native shrubs. I’m now working on my PhD at Penn State exploring the occurrence and potential impacts of this extended leaf phenology of invasives. I’m trying to get a regional perspective on this, and so have started a citizen science data collection campaign called Shady Invaders through the National Phenology Network. The landing page contains the species lists and links on how to start collecting data. Datasheets can be printed or there’s also an app for mobile devices. Please help spread the word.
