Buckthorn changes the soil nutrients

Similarly (kinda), I believe that Autumn Olive fixes its own Nitrogen, which allows it to thrive in areas with poor soil. Generally invasives will follow a positive feedback. A little of bad leads to A LOT of bad.
 
I read it. I'm not sure what I'm supposed to take away from it. Hope the buckthorn takes over a farmed out area to rehab the soil?
 
Black locust does the same. Invasives not good
 
Here's what I got from the article...buckthorn increases N and Ca levels of soil tested. Neither of those "facts" causes me any concern
I felt it might be improving the soil after reading the article. At least improving the sand where so much of it grows on my place.

I don't think you were "supposed" to get something from it positive or negative. It wasn't so much meant to be a good or bad, but rather just reporting that in fact it does change soil composition, and in what manner.


As far as the "residual effect" (I forgot the exact term that was used) I wonder why the berries didn't germinate in the seed bank. Overall I think it did a really good job of relaying "science" to "everyday people". I use quotes because I'm a firm believer that we can absolutely use and understand science without science degrees, it's just a matter of knowing terminology. There's no reason that "everyday people" can't use science.

My thought as well. The "catch" I suppose is that it improves the soil for further buckthorn expansion/invasion. Sooner or later, some bug or disease will come along and take care of the buckthorn. Then that improved soil will be there for other plants to take advantage of. Of course, that may take a couple centuries

I'm still waiting for that to happen for Autumn olive! From what I've seen if you knock the A/O out and put something in its place, it won't dominate, but will still definitely be present. IME, the problem is when you have mature bushes that put out berries that subsequently get crapped everywhere within a few hundred yards :P

They're certainly good at what they do! Most of these invasives have a short(er) lifespan, but reproduce heavily. It's pretty neat thinking about how different reproductive and survival strategies have evolved. I at least think it's pretty darn interesting!
 
If you spend anytime reading on permaculture forums....or even on NAFEX, you'll find a great number of people who are very interested in AO and who are planting it with enthusiam

Oh yeah, it's all over the Michigan Sportsman forum. I just don't really see where it can grow that natives can't take its place. Wetter areas? elderberries, blueberries, chokecherry, aronia. Dry areas? Hazelnuts, am. plum. I can certainly see the appeal in regards to its hardiness and vigor, but I think that in the long term it's kind of a silly thing to do when we have so many options here in the Midwest.

I thought the article said that in one study, once the buckthon was reduced in numbers the soil reverted back to it's original form. I imagine it depends on the type of soil-sand would revert more quickly.
 
Those varieties you mentioned are not nitrogen fixers, while AO is. I'm not an AO proponent, just saying that there are reasons to grow it. The berries are very high in lycopene too...many more times concentrated than tomatoes. Some interesting research out there on lycopene

That's true, and most of those species, in fact most shrubby fruit producing species desire high N. I understand completely that there are reasons, and I can be sympathetic to them. I think the best word I can use to describe it is silly. I'm not vehemently opposed to anyone planting it, I just think it can be done without.

I would suppose so. I know in our backyard where it's wet, we have seedling every single year. In the next few years I've convinced my parents to let me put in some ninebark and ROD. They kind of like the thick barrier it gives, so they were a bit hesitant.

Some pin head 100 years ago thought the same way when he planted that crap. I'll carry scars the rest of my life from those thorns. The only thing interesting about invasives is their death!
 
This reminds me of the discussion we had about weeds telling us what was wrong with our soil. For example, clover would emerge to dominate a nitrogen depleted soil.
 
Invasives don't grow because of soil issues.

I'm 100% against them, I'm just saying that the concept of a single species changing nutrient cycling in an entire mini-ecosystem is interesting. While I've yet to find Buckthorn on my property (luckily it's A/O, Barberry, and MAYBE multiflora rose), I have the same feeling about AO. I can't tell you the number of times I've had those thorns whip back and then break off in my skin. Not fun.
 
How do we know that buckthorn, AO, MFR, garlic mustard etc. aren't filling a "niche" that is available due to mismanagement of our soil/forests? Now that they're here and well established, does it really matter? I can safely say that none of my neighbors know what buckthorn looks like....if I eliminate it here and they don't, what have I gained?
I know they fill a niche due to excessive deer numbers. The deer browse native and the invasive flourish. If u want a sea of garlic mustard, cause nothing else will grow. I can drop some off to find out?

While that may be true, every landowner owes it to the local ecosystem to do everything in their power to refill that mismanaged "niche" with native species and eradicate any and all non-native invasives. It all boils down to responsible land ownership and management, unfortunately all to many landowners don't care enough to take the time to be responsible owners.:mad: Thus you end up with comments like the last two sentences in stu's post, which are unfortunately spot on.:(
 
I would agree stu, the hypocrisy starts at the highest levels and the state Hwy Depts and DNR's do little to combat this in many situations, so why should the common man concern himself with it. I get sick of contacting the USFWS about flushes of purple loosestrife growth out in the Upper Mississippi National Wildlife Refuge(which I do multiple times a year) and having them do nothing about it. Given it is a Federal Refuge, I will not pull them myself for fear of being reported by some idiot that thinks I'm destroying the plants on the Refuge. The thing with native invasives is that they usually have a natural "control", i.e. something that keeps them from taking over and becoming large monocultures. Granted, many of those "controls" are not present in areas where the potentially invasive species are present, so the "control species" is technically irrelevant in those situations, but it is far easier and more responsible to use those native controls than it is to have to introduce another non-native species to control the non-native invasives that are present, which we do all too many time without knowing the whole of the consequences of the situation years down the road.
 
I'm changing the topic here, but look at the invasive species in our lakes. Once they are here, they are usually here for good.

Recent report was that spiny water flea is eating the zooplankton and might be a reason for young walleyes not surviving in Mille Lacs.
 
I agree with both of you guys. I've contacted a few state parks on their infestations with Phragmites and buckthorn, and from what I've seen, their biggest problem is that it's such a resource heavy (time, equipment, labor etc...) task that they can't get all of it done. They do little sections and then go from there. My view has evolved a little bit in the fact that I no longer see it necessary/possible to eliminate ALL of the Nonnative invasives on my land, but more to cut them back severely enough that through planting and natural regen I get natives to fill their roles of dominance. Like you said, I can do it, but since state land is 300 yards away, and my neighbors love the stuff, I'll always have it. I guess I see it as an impossibility rather than something I don't want to do. That's kind of my focus with the GRIN project I have. Get as many other berry and seed laden bushes out there for the birds to shit out, and eventually I'll have more natives. Once more of them are sprouting, I can cut down the A/O in new places and hopefully they'll transition to a native of some sort.

Don't get me wrong, I'd be 100% ok with eliminating all non native invasives on my property, however I don't see it as an extremely efficient way to improve habitat. I think that at least on my 20 acres, going 1000 square feet at a time is a better and more manageable way to go. Although I still walk through the woods turkey hunting with a little spray bottle of gly in case I find some barberry. I just don't want that stuff to get a huge foothold, and preventing it is easier than trying to do what I'm doing with A/O
 
Sorry to hear that rally. I found out there is one technician to chat invasives in the entire county.
Some parts of the government don't know. I would complain if you know some form of the government is planting invasives. They probably don't know
