Focused on the very important environmental issue of noxious exotic species from around the world invading, degrading and destroying native ecosystems and costing nations billions.

Our submission content consists of news, educational resources, discussion and photos of field sightings.
The goal of the sub is to better inform and educate our subscribers on the critical topic of invasive species.


An invasive species is an organism not native to a specific location, with a sustained population and which damages the environment, human economy and/or human health

This is an important topic, since many organisms, especially island populations, are threatened or already extinct at the hands of these noxious invaders.

    Tree of heaven samaras/seeds and leaving leaves

    I’m in the process of flipping my lawn to make more native beds along with improving my clay. My plan was to mulch some leaves and leave them as they fall in some sections. I’ve been battling thousands of TOH samaras from a 60’ female tree in a public easement that I’ve been trying to kill. Thankfully they are removing it next year for a sidewalk, though they haven’t done proper mitigation. At least I can watch for seedling as they sprout over there if nothing else. This is the first year it’s done this and it’s been the scourge of my existence. I’ve literally vacuumed the rock beds around my house so they didn’t sneak by my foundation. I’ve disposed of a good majority, but I am losing time before winter and need to mulch. Am I in for a TOH field in the spring if there are some mixed in? I mean, there is no way I can they every single one, though I’ve obsessively tried. Anyone have experience with this?

    Y'all got any advice for clearing multiflora rose?

    Hello, y'all, I've recently been helping clear the invasives from my parents' 6 acres. I've been able to deal with the honeysuckle easily enough, but the multiflora rose has been taking me longer to get through than expected because of how dense and thorny it is. Is there any specific equipment (clothing, tools, et cetera) or techniques that y'all recommend to get through it faster?

    Killing Buckthorn Creatively

    I have a house with a shrub privacy barrier between myself and my neighbor. All of the plants are on my property and unfortunately the once all lilac barrier has become riddled with buckthorn(some are essentially full trees at this point) I want to kill the buckthorn and replant the lilac that was originally there but my wife doesn't want to have to see the neighbors for a short time. However....if the buckthorn was to just, "die on its own" then we could move past that issue, remove the invasive species, and improve the look of the yard. What would you recommend to have the buckthorn, "die on its own"? I've tried drilling a hole with a 45° downward angle and filling it with glyphosphate with limited success. Thinking of trying and filling it with gas or any other harsh chem, but would be open to ideas!

    App says Wisteria. Cant be sure. Help please.

    East Tennessee. Zone 7b. Photo taken last week. I need to know if I should remove this and follow the trail to remove the rest of it. Thanks

    How can I deter cats from hanging out in my yard without deterring foxes?

    Basically the title. Midwest USA, half acre suburban lot in a neighborhood with big, old oaks and maples, adjacent to a greenbelt. We like to see the foxes but how do I keep the cats away?

    Is it realistic to start a service for kudzu removal and soil recovery using famine crops?

    I'm considering starting a service that not only removes kudzu but also plants famine crops to aid soil recovery and offset removal costs. The idea would be to use a mobile setup that combines a bioplastic production plant and a food processing plant, making it possible to sustainably harvest and utilize kudzu on-site. The reason for a mobile plant is the vast scale of land in U.S. states, which makes centralized facilities impractical. In traditional Japanese methods, efforts were community-centered, but here, mobility is essential.

    We’d also plan to utilize ground-penetrating radar and drones for efficient monitoring, with a focus on producing and using our own bioplastic mulch sheets as part of a closed-loop system. Do you think this is realistic? Are there examples of similar services or business models? I’d love to hear any thoughts or advice

    Invasive Alien Species innovation challenge (tech/solutions/capabilities)

    We’re exploring established and emerging IAS capabilities for a global mining business and their efforts in post mining rehabilitation.

    The innovation challenge can be found here: https://unearthed.solutions/u/challenges/eramet-biodiversity-challenge

    Please sign up and explore the examples and details further via this link.

    Key opportunity areas are as follows:

    Detect & Monitor IAS: Solutions may look like robotic/sensor survey technologies, inspection protocols, or other novel detection techniques. Contain IAS: Solutions may look like biosecurity measures, novel physical or environmental barriers. Control IAS: Solutions may look like novel environmentally friendly biological sprays, targeted eradication strategies, or other mechanical/chemical treatment protocols.

    Drop me a line here or feel free to share those in your network who may be applicable.

    Thanks!

    Help with neighbor’s buckthorn

    Hello! I’m a new homeowner with 3/4 acre land in suburban Chicagoland and I want to create an eco-friendly yard. My back neighbor has buckthorn that hangs over the fence onto my property. I am working on getting friendly with them so I can broach the topic of getting rid of it. In the meantime, I have some questions about what I can do.

    -There’s a thick layer of berries on my property. Should I dispose of them and what’s the best method?

    -Should I cut the branches hanging in my property? If I do, how can I dispose of them without spreading seeds? (My city doesn’t allow me to burn them.)

    -Pretry much nothing (except poison ivy 🥴) grows along the fence line under where these branches hang. Is there anything I can do with that land? Something native that will grow there? I’m also thinking of making a compost pile there, but would it be damaging when buckthorn berries fell in?

    There is so much information out there and I feel like I’m not finding practical answers I can use. It’s overwhelming. Any advice is appreciated!

    Are we losing the war? :(

    My immediate area is all being overrun by invasives. Honeysuckle, European buckthorn, burning bush and lots of invasive weeds like Canada thistle. It feels like we are losing the battle and losing the war and it feels hopeless.

    Oriental Bitterroot mitigation -- glyphosate a problem for nearby trees?

    We have loads of bitterroot that grows along the fenceline of a nearby park. The parks dept. does not have the resources for invasives mitigation and just hits it with a string trimmer. But inevitably it grows big enough to shrug it off and then it gets bushy.

    I try to prune it all once a year, but I'm considering using glyphosate this year. The problem is there are trees within 15' of where the bitterroot is rooted, and this being a canopy-starved city I'm much more concerned with protecting the trees than I am with fighting this dumb vine.

    So my question is, is a foliar application of glyphosate any risk at all to any of the nearby trees (liriodendron, white oak, baldcypress, london plane, sweet gum)? If it is, I'd rather just hack it back until it starves for light. But if not, I'll go with the blue stuff.

    E: lol, Bittersweet, sorry.

    Japanese knotweed minimum unit of stem to grow?

    Looking to get my facts straight about how this plant grows. We have some in the hood and I saw that someone mowed through it. Would bits of the shrapnel from that be a regrowth risk?
