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'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.

Did a quick Google search on this and not quite sure what it is. Some searches suggested Knotweed amongst other plants. Could anyone help identify this please? I'm in the UK if that helps.
I'm so tired of this plant. I would love to give some native plants a fighting chance by spreading around native seeds but I'd rather not play god in fear of making the issue worse, or creating an entirely new problem. Talked it over with a couple peeps and the takeaway is that these efforts would be futile, and that we ought to adjust to their presence. Im young naive and in denial because come on there has to be something I can do, right?
Any ideas?

I was appalled at the number I saw. We need a sort of Johnny Appleseed in reverse, who goes around cutting down Bradford pears. If you’ve got one on your property, PLEASE get rid of it.
hey y’all! not sure if this is the right place, but i thought i’d ask anyways. i’m from california, and i saw a mediterranean house gecko outside in my backyard. from my research, it seems like they’re not as big of a pest here as they are in other states, but i’m sure i should probably still do something with it. keeping it is not an option. should i leave it be, or do i need to euthanize it? please let me know!
Acclaim can't be used near water, and I want to avoid non-selective herbicides that will kill other plant species. Are there wetland safe herbicides that will leave native grasses intact? Right now I have a big problem with Stilt grass on stream margins and swampy areas where the fluctuating water levels spread the seeds and disturb the soil.
I'm in northeast Ohio, heavy clay soil, urban environment, old house with lots of perennials. This established itself since fall and wasn't visible then. The roots are fat (1/2" or more), white on inside, sometimes whitish, or purplish on outside, and only 1-2 inches down, sometimes less. Spread quick, purple buds that almost look like hosta buds come up just above surface. Grew quick and needed a fork to pull. Seems to like partial sun. Tried to get parts but tough to get all the tubers.
it’s growing through power lines and right on the property line too. seedlings coming up everywhere.
