/r/invasivespecies
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.

I have some rhododendron and Holly that have been overtaken by Multiflora Rose. I crawled in there and identified many sources. I cut those stems ... Some were 2 to 3 inches in diameter, some were more young canes.
It is hard to know if I got them all. Hard to see where everything actually originates. Hoping that eventual dieback will tell me if I got all of them or not.
I plan to go back in and recut and apply an herbicide to the cuts.
Thanks!
We just moved to a property with a pond; horsetail ferns have taken up residence in and around it.
If they’re not hurting anything right now, should I just leave them? Or should I try to intercept them before they start seeding/breeding more?
Opinions welcomed
This is kind of a silly question but I was up all night wondering about it. I know certain fungi like Ganoderma cause root rot on living woody plants. I have 6 mature honeysuckles on my property that have been there since I moved in. They're a pain in the ass to remove because they just keep coming back. I've tried local herbicides to no avail. What if? - and this is just speculation, I'm no scientist- you found a dead part of the honeysuckle and implanted spores in there? Would the fungus be able to take hold and be a parasite on it? I found a local news article about a college student using Reishi mushrooms on buckthorn to kill them, but I can't find the link right now.
This may not be the right subreddit, but I was hoping someone could offer speculation on this idea.
I’m in Missouri and rent a house near a woodsy area. I’ve got a wall of shrubs with mulberry trees, boxelder, eastern red cedar, some grape vine, European cranberry, and a whole lot of bush honeysuckle. I rent so I can’t exactly go full destructor mode and chop it all down but it’s starting to strangle the trees and decimating my ground cover. Any advice to keep it under control given that I rent and shouldn’t make drastic changes to the property? Pruning recommendations, or native plants that might compete better? Thanks!
Hi! I have some Callery Pear Tree clippings on my windowsill from some trees I cut down (because they are invasive) and I noticed my cat chewing on the leaves. I can’t find much information on whether the leaves are toxic or not. I found that the fruit is safe in moderation and that the seeds aren’t great for consumption, but this isn’t very helpful considering that the clippings I have will not produce fruit so I don’t have to be worried about that. I know this is more about my cat than an invasive species but I thought I might as well ask here just in case. I just want to know if I should be worried for my cat’s health at all. Any information is welcome!
Do Nutria ever slap the water like a beaver? What i saw didnt have a wide paddle tail - it seemed the same width from base to tip but it slapped the water
I'm just wondering if anybody here can ID it, if it's an invasive grackle or an endangered one.
My theory is that Asian bush honeysuckle (ABH) is a choice habitat for mosquitoes during the day. It creates extremely dense cover which protects them from sunlight and predators. It also blocks wind, which helps mosquitoes since they are weak flyers. Finally, it allows trash to accumulate which provides a place for mosquitoes to lay their eggs. These are just my observations but have there been any studies?
There is a large grove of young bradford pear trees by my work and I really want to get them out before they are too big to be removed without machinery! Best way to remove without them coming back?
I also have some full grown bradfords by my home and would love some tips to prevent further growth/invasion to encourage the city to remove them. they’re very obviously for aesthetics and not function.
I’ve had a couple of stems of JKW each year for the last 5 in my garden. I’ve always painted foliage with glyphosate to the appropriate dilution during flowering. I’ve just found a small shoot about 2-3m from where it has previously been (no regrowth here yet). Is it worth treating this stem now or wait until flowering in August? I’m in UK
They cause erosion by digging their burrows which causes millions of dollars of structural damage, they spread salmonella through their feces, they eat nickerbean which is the host plant of an endangered butterfly, and some snails were found in the stomachs of a few iguanas in one park.
But none of that seems THAT bad from an ecological perspective. Besides the butterfly, it doesn't seem like they're endangering any species?
My wife and I have been waging a slash and burn war (without pesticides) for the past few years. This year, we have some plants sprouting up that could be knotweed but don't look like our usual first sprouts. The first two photos (with the big green broadleaf plants) are what has been popping up all over the spot. Can you help identify the plants in the first two pictures? The second two (with the little reddish sprouts) are what we usually see sprouting up around this time of year.
There are definitely some similarities but it's still different than what we're used to. Naturally, we want to start clipping the knotweed, and will start where we recognize it, but we also want to encourage other plants to grow. Honestly, we'll let just about anything grow as long as it isn't the knotweed. Thoughts and input are appreciated.
Edit: We are not looking to use pesticides at this time.

Im portuguese and these fucking trees are everywhere, I’m considering ways I could wipe them out en masse without harming the rest of the ecosystem, Any eucalyptus diseases or other methods that wouldn’t require spending hours on each tree would be excellent
In regards to the legality of this I only mean to affect the ones on public land which aren’t the property of someone
Hello, I am currently studying about Signal Crayfish and there impacts on the UK environment and I need acknowledgeable people who have a passion for Signal Crayfish to participate in my questionnaire. It would be highly appreciated. https://forms.office.com/Pages/ResponsePage.aspx?id=Hg4R8gzHJkuDOc_OaZtztQaQTf5c2G1EpwyfAKSB_c1UQ0FCVTVKSzE3NTlGWEpYSkVDMU84N0FESi4u
Just read about Red and white Mulberry do this. I also seem to remember that perhaps native wild grape and porcelain berry maybe do this? Eradicate or no?
Saw this growing out of neighbor 's backyard and Google reverse image search returns Japanese Knotweed. The stem doesn't look red like pictures i foumd online so can't really tell if it is what I think it is.
