These plants look completely dead but come back in the same spot the next year. This was also the experience of a land manager at a county prairie restoration visited during the Grassland Restoration Network workshop at Fermi Lab. At Nachusa Grasslands, they have been spraying bird’s-foot trefoil in a former pasture for 30 years and have not been able to eliminate it. <br /><br />In contrast, when I removed these species from a native plant garden by digging up the entire root, after the third year not one plant has come back from root fragments and no new seedlings were produced. These plants have not been seen in this garden since I did this work.<br /><br />Digging up plants by the roots would not be acceptable in remnant prairie. However, I have used foaming glyphosate using Greenshoot’s foaming agent and dispensers with good success. I’ve found four percent active ingredient to be the minimum amount that will kill most of the crown vetch, ~95 percent, on the first pass. I had previously covered the entire plant with this concentration of herbicide. Next year, I will be trying to apply herbicide to varying amounts of stem length just above ground level to see what is the minimum amount of herbicide that will be effective.<br /> <br />Entire handfuls of stems can be treated all at the same time by squirting foaming glyphosate into the center of the bundle and squeezing a few times with a glove covered hand until all the stems are covered with herbicide. This is much quicker than treating stems individually. <br /><br />If the canopy of untreated leaves is maintained above the stems, then this will help prevent rain from splashing herbicide onto adjacent plants. My experience has been no damage to adjacent plants is visible if the portion of the stem covered with herbicide is under a canopy of untreated leaves. This method will likely be the best way to eliminate crown vetch from high quality areas without adversely effecting adjacent native species.James McGeehttps://www.blogger.com/profile/12813312887957290703noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-19203664175251809052018-03-02T06:28:50.749-08:002018-03-02T06:28:50.749-08:00Yes, it is not that difficult for a skilled and de...Yes, it is not that difficult for a skilled and dedicated person to control crown vetch - especially on just an acre or so, as at Palatine Prairie. I'd recommend cutting all the stems of conservative legumes and composites before spraying with Transline - or other narrowly focused herbicide. <br /><br />A number of people with skill (and Illinois herbicide certification) volunteered to help, back early in the history of this infestation. The problem at that time seemed to be that no one in authority seemed to be willing to authorize them to go ahead.<br /><br />Does anyone if the problem there has been solved?Stephen Packardhttps://www.blogger.com/profile/01811489977185760340noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-22220530827497489562018-02-28T11:21:53.613-08:002018-02-28T11:21:53.613-08:00Tom Vanderpoel recommended the following strategy ...Tom Vanderpoel recommended the following strategy for this prairie.

Despite our vigilance, however, we have seen how quickly a few "missed" sweet clovers can proliferate. <br /><br />We routinely acknowledge that our restorations will always require "some" management, but we haven't squarely addressed how our considerable successes will be sustained over the coming decades. Honest thinking about the future is likely to impact how we organize our work today. For example, it might cause us to more or less aggressive about some weed species that we now manage; or it might lead us to initially be more adamant about eliminating internal (former) fence row contours which complicate management. Management will have to become simpler to be sustainable.<br /><br />At our site, a small part of the solution may be to dedicate a portion of future distributions of the endowment we are building to a structured long term management plan. Admittedly, endowments are not realistic for many sites.Berniehttps://www.blogger.com/profile/17440075433908583442noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-51126864549366901152015-08-08T09:10:00.251-07:002015-08-08T09:10:00.251-07:00I really think with some organization a lot of the...I really think with some organization a lot of the work could be completed this year. The key is to focus on the edges with the cut and herbicide method until the seed drops then work on the interior after the seed has dropped. Of course as much seed as possible should be bagged, removed from the site, and preferably burned.<br /><br />I do not think it would take thousands of hours. I have cleared heavy infestations by hand before without the help of herbicide and I typically am able to progress over 100 sq. feet in an hour. An acre is 43,560 square feet. From your map it appears that 60 % of the 2.5 acre preserve is heavily infested which calculates to one and a half acres of dense crown vetch. The math follows.<br /><br />1.5 acre * (43,560 sq. ft/acre) / (100 sq. ft/hr) = 650 hrs (rounded)<br /><br />I think the work might progress twice as fast with the use of herbicide, which requires much less effort than digging.<br /><br />This amount of time commitment is impossible for the steward. This is the reason the battle is being lost and now appears overwhelming. However, if the stewards as a community come together this problem could be tackled.James McGeehttps://www.blogger.com/profile/12813312887957290703noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-91928351076477589752015-08-08T06:50:43.271-07:002015-08-08T06:50:43.271-07:00James, thanks for finding this interesting method....James, thanks for finding this interesting method. Sadly, since the seeds have already formed, it wouldn't work this year. The "cut stem, herbicide, and remove" approach that is recommended at the end, in theory, would. Unfortunately, it would probably represent thousands of hours of work. I wonder if there would be willing volunteers or funding. Sadly, from what I've heard, most of the many people who volunteered to help earlier (but couldn't get approval) now look at the problem as overwhelming. It probably would need a quick contract crew to "hand combine" the seeds out of there before they fall. Perhaps even that isn't worth it, except in the "outliers" and edges - as the seeds have been dropping in the heart of the infestation for many years. They could be cut and herbicide, with a lot of work. But if the prairie is to be saved, the effective work in 2016 and 2017 would probably have to start much earlier in the year.Stephen Packardhttps://www.blogger.com/profile/01811489977185760340noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-34735045164581260972015-08-08T01:06:28.460-07:002015-08-08T01:06:28.460-07:00Here is another method that you will probably like...Here is another method that you will probably like better.

I think you do not really want to experiment with broadcast spraying herbicide, even a selective one, on such a high quality remnant. I have done some control of crown vetch by digging it up by the root. When we find the odd off one while walking restoration areas looking for sweet clover I use my NRG Pro Weeder to dig up crown vetch by the root. I have found that digging crown vetch up by the root is difficult, but not impossible. The problem with crown vetch is it is rhizomous and the roots are very brittle. This makes digging it up much more difficult than tap rooted plants. The roots tend to break and you will rarely get all of them. If you dig up the plants by the roots there will have to be follow up for a couple years to make sure all the fragments of roots have been removed. This is also a very labor intensive process. I estimate it will take a minimum of 150 hours of very hard work to initially dig crown vetch up by the root for an infestation of this size with progressively less work required in each subsequent year.James McGeehttps://www.blogger.com/profile/12813312887957290703noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-49848048171757119662015-08-07T13:58:24.669-07:002015-08-07T13:58:24.669-07:00Good thinking, J.Schlesinger.

But it only told us which sites to buy or protect from development. We could use something that highlighted management challenges and priorities. Buying land is no longer conservation's most important challenge. To conserve biodiversity and natural heritage, good stewardship for the lands already protected is very much more important.Stephen Packardhttps://www.blogger.com/profile/01811489977185760340noreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-4872171454886842262015-08-07T06:45:35.362-07:002015-08-07T06:45:35.362-07:00This kind of transparency and accountability is mu...This kind of transparency and accountability is much needed. Back when the dedicated George Fell headed up the Nature Preserves Commission staff, the Commission issued a report every two years on the state of the preserves. It was frank about the problems each preserve faced. Some agency owners resented having such needs "aired in public." But the straightforwardness of the reports helped educate the public and inspire helpful action. Robb, thanks for the reminder.

These prairies are being managed by people who want to preserve these areas as a seed source for nearby restorations.

Perhaps one of the essential questions should be: When stewards, agencies, landowners, or NGOs do preservation or restoration, do they understand the need for continual intensive "search and destroy" efforts against the invasives they currently have and the ones that are on the way? They need to know that the work will never end, and dedicated people need to be on the ground to find and control invasives. <br /><br />Last weekend we took a field trip to Kankakee Sands. They actually have one field of perhaps 100 acres (out of a 7600 mostly prairie restoration) that they put back into agriculture (crops) because they had lost the battle against Bird's foot trefoil! I don't think that most landowners have any idea that this can happen.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-201378124228558245.post-17657283016770579522015-08-06T12:26:39.190-07:002015-08-06T12:26:39.190-07:00Each year the Illinois Landmarks organization rel...Each year the Illinois Landmarks organization releases a list of the state's most endangered structures.

Joel Greenberg's Natural History of the Chicago Region details some of the struggles, including the successes (Goose Lake Prairie), failures (Buffalo Grove Prairie), and instances that were a mix of failure and success (Indiana Dunes). In these days of budget cuts and unending development, when society seems determined to sink under the weight of its own materialism, it is vital that we collectively find the will and insight to address Steven's five questions. In fact these questions strike me as a sound platform for a mini-summit of stewards and land managers who own Nature Preserves. Like Langham Island, Palatine Prairie can still be saved.<br /><br />One final thought: It is a cruel ironic twist that the railroad which likely sustained the prairie for years through accidental burns would become the corridor for the invasives that now threaten it.Markhttps://www.blogger.com/profile/04608850767431630602noreply@blogger.com
