Exposing seeds to extreme prolonged heat (such as boiling/simmering for an hour) kills them, right? Or is this an over generalization/something that I made up?

I was just listening to the In Defense of Plants podcast on pawpaws and was encouraged to hear their report that pawpaws are such good colonizers that they can outcompete invasives like stiltgrass and bush honeysuckle.

We all know nature abhors a vacuum, and this seems like it could nicely (and natively!) fill a woodland understory in a large portion of the US, while providing delicious fruit! Deer don’t seem to browse it, either. This seems like a real powerhouse of a plant.

I don’t live in an area it grows, but I’m heartened by the news wanted to share.

When trying to get rid of JH, do I need to bag and or burn the JH? Or can I throw on brush pile in the woods? Also dealing with some Asian Jasmine and wonder the same. Or if I let it dry up then can I throw on pile?

Warm greetings to all - I'm in a group of volunteers working to control invasives in a large tract jointly owned by several conservation minded land trusts. Most of the land is redwood forest in coastal central California. It's been logged since the late 1800's, and was occupied by native people for thousands of years prior, so there are clearings on the property that are prone to invasion by non native thistles, among other things. We are trying to interrupt these thistles' life cycles at all stages, by any means necessary.

Have you ever used a portable vacuum cleaner or similar device to capture seeds from ripe thistle heads? I'd like to try it later this year. We have some big monocultures of annual/ biennial Italian and milk thistle, and Urospermum picroides has just arrived in the past couple of years :-(((. There are large backpack style vacuums, used by office building janitors, that might work well.

All thoughts and opinions welcome, especially if you've tried this.

Edit: We do dig them up, cut off flower heads, and even use herbicide, sparingly, when it's a dense monoculture. Herbicide is being phased out, which is just as well in my opinion. But we can never get to them all before they go to seed, so we're looking for ways to address that part of their life cycle. Willing to consider just about anything, especially to stop the U. picroides before it reaches critical mass.

i know that it's recommended to pour boiling water on them or soak them in vinegar, but oftentimes i see them when i'm far from home. i've been smearing them across the sidewalk to try and ensure no splitting-- is that a good way to get rid of them, or is there a better one?

i've caught a few lizards in my time and i've only recently found out they were invasive. i also recently discovered a corn snake living near my house in south FL. if i catch any brown anoles, is it efficient to drop them into the bark where he lives?

I have about 40 acres of mountainside and creek bottom in the southeastern United States. The main species I’m fighting are barberry, multiflora rose, bittersweet, and stiltgrass. There are smatter amounts of Japanese honeysuckle and autumn olive, and a couple patches of tree of heaven. Some barberry is at 6’ tall, for age reference.

I spoke to the department of forestry, and they told me they can prescribe burn for me at $25/acre, which seemed imminently reasonable.

I know a burn won’t eradicate anything, but may give me some breathing room. What I don’t know is if any of these species react positively to fire.

Can someone help me identify this plant, please?

Concerned that it’s Japanese knotweed as it is hollow and looks like photos online. Old photos from outside the house suggest it could be a rose bush?

Thanks in advance!

From what i heard prisons don't feed inmates very well and cheap out on their meals where Ramen has become currency worth much more than it does on the outside so it makes me wonder can we just unload a large portion of captured green crabs on them in bulk for cheap as it seems like it would help both causes as it seems wasteful just to kill them when so many people are going hungry

I've been curious about invasive species for a while and I am specifically interested in how their native (non-detrimental) role in an ecosystem changes into something pretty ugly when they show up in a new place where they don't belong (I've also been reading about green mountain on ascension Island) and I got a wild idea.

What if a researcher were to find/make an isolated island in the middle of the pacific ocean with no native plant or animal species (i.e. no existing ecosystem to destroy) and introduce a whole host of the most notorious invasive plant species? Then once those plants are established, introduce a bunch of the worst invasive animal species as well.

Basically then you just sit back and observe and report. What happens when species with a penchant for invasion are the primary colonizers in a new location instead of the invaders? And what happens when ALL the species in an area have the chops for invasion? Do you think it's possible that a functional ecosystem of some kind might emerge? Or would you simply have some kind of battle Royale that would end with all animal life erased from the island and a single plant species taking over? Or the world's most intense evolutionary arms race?? Something else?

(let me know if any of you are a crazy curious person with deep pockets and have a desire to fund this).

(Edit: To be clear, this is intended to be a thought experiment primarily, Im aware of the issues with containment, suitable locations, and the probable R.O.I. I understand that just setting a bunch of known invasive species loose in a new place is playing with fire. I know this would need to be "done in a sandbox" of sorts, or even simulated with computer models, if it was ever going to happen. But still, I'm curious as to thoughts about how this might play out, or if anyone is aware of anything even sort of analagous to this)

I live in Vancouver. I recently tried ice plant at a restaurant in China on a trip abroad and loved it. I would love to plant some in my garden but don't want to introduce a potentially invasive species into my area.

The seeds I'm looking at online are listed as Mesembryanthemum crystallinum or Delosperma floribundum. Are these invasive in Vancouver?

On other posts, I've read only the carpobrotus edulis variety is invasive, and not other breeds (link: https://www.reddit.com/r/gardening/comments/13373a8/trailing_ice_plants_in_our_garden_are_in_full/ )

Thanks for your input!

Has anyone successfully girdled buckthorn? I have several of this size and am hesitant to use herbicide. Any suggestions would be appreciated, thank you.

I’m a Forest Ecologist working in New England. I was doing fieldwork yesterday and saw this monstrosity of an Asiatic Bittersweet. iPhone 12 for scale. Right part of the trunk is over 12” in diameter. Can’t imagine the age, not to mention how many scions it has produced. Tragic really. Will be back to murder and collect a cookie of the base as a trophy.

I’m going to be tackling a significant infestation of Japanese barberry and multiflora rose, and this stuff is just tearing my clothes apart. I’ve just been wearing typical work clothes—denim, red wing boots, carhartt. But I need something that offers more protection.

Does anyone have suggestions for clothes that can handle this stuff? I’d also appreciate suggestions on gloves. Even thick leather ones don’t seem to be enough.

Edit: I’m not sure why I mentioned the boots, I don’t need suggestions on footwear. My feet are the one place I’m not getting scratched to pieces

We acquired land and have a forested section overrun by English holly. It is mostly under 3 ft high but pretty dense. We can't walk through it. And the area is something like 0.20 acres.

We are planning on going through with a power tool and cutting it down at the base, raking up and disposing of the waste, laying coffee bean bags down (I have an abundant supply) and then mulching very thickly with wood chip mulching (I have an abundant supply of these as well). Coffee bean bags and mulch are free so it's really just a matter of how much time I want to spend laying it down; I much prefer that to pulling holly out.

Our goal is to get rid of this holly problem for good. I know that even with the most effective methods of removal I will have to maintain areas that have resprouted. Any thoughts on how effective this method might be? I don't see this method talked about online so I'm concerned it's going to be a waste of time and the holly will just grow right through the decomposed coffee bags and mulch.

Thanks!

hi! Im new here but my class has a project about Alien/invasive species and i have to unterview an expert. I do not have or know anyone in my personal life that is educated enough on the topic to interview and it would be such a great help! If someone knows anyone or you yourself are a scientist that knows a thing or two about the topic please contact me through instagram or Facebook. You will of course be credited and memtioned at the presentation of our Project at conference in Instabul, Turkey on the 26th of March!
