Photograph via snooOG

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.

    Teasel removal?

    I am working on a property owned by my University, and there is a large amount of teasel and callery pear (both highly invasive for my area) on it, and I was wondering what would be the best method of disposing of it. I was thinking of putting all the clippings into a burn pile and burning it. There is so much that bagging it and transporting it to a landfill would be far too many trips and I don’t want to use plastic trash bags. Any suggestions will be helpful!!

    Will topsoil from a big box store contaminate my garden with invasive jumping worms?

    I'll soon be putting in raised beds for several different varieties of plants native to my part of the us and i need to level the land (with dirt), most likely from home depot or another big box store. I live in the southern usa where jumping worms are a problem (to my knowledge not in my area) and it made me wonder if the bagged soil could contaminate the surrounding area. I dont want my dirt turning to coffee grounds. If there is a substantial risk, how do i prevent their introduction?

    Is removal worth it?

    I have a very large patch of stiltgrass in a creek area on my property. I planned on removing it but have now read it takes at the very least 5 years. I also will be moving roughly in 3-4 years, making this situation very tricky. Is it worth it to go ahead with removal and attempting to plant vigorous natives a year or two in?

    Side question-will i track stiltgrass's seeds to other areas by walking through it, even when it hasn't seeded yet?

    Large Wintercreeper (Euonymus fortunei)

    I found this while doing invasive species removal in my town. Its about 10" in diameter. For reference, my chainsaw has a 10" bar. It is actually several vines that have grown together. the top of that tree was a mess!

    Best, readily available product for homeowner for buckthorn

    I am working on removal of buckthorn, honeysuckle, TOH, and knotweed from my property. For winter, I am focusing on the buckthorn and honeysuckle. I would like to cut and treat the stumps. I’ve done this in a volunteer capacity with local eco organizations. We used garlon and typically worked on this during later fall into winter.

    As a consumer walking into a place like Home Depot, ace hardware, what am I looking to purchase? I can find triclopyr but the label directions don’t match how I’m used to using it. They seem to want you to spray them on the plants when they are leafed out.

    Am I headed in the right direction with these? I don’t know if this sub allows links, but I’d love to know exactly what I should/can buy locally as a homeowner that will do the job.

    Thanks.

    The attack of the earthworm

    I have seen this board in our botanical gardens and forest's hiking trail, and infect i have encountered some very strength earthworm as they are bigger and more " jumpy " , I never know earthworm are introduced species and never thought they are bad for the forest. This is in Burlington, Ontario, Canada.

    Any ideas on how to keep squirrels out of my sparrow trap

    I built a sparrow trap for this winter hoping to reduce numbers in my area. When I leave the trap out, they just get raided by squirrels and sparrows don’t go in.

    I built mine similar to this one here with the elevator mechanism https://m.youtube.com/watch?v=dW2gboV8XHA&pp=ygUWU3BhcnJvdyB0cmFwIHJlcGVhdGluZw%3D%3D

    European Starling help

    Hello,

    I’ve tolerated the starlings that flock to my property each winter (about 40) for two years. This morning I watched them kill a red bellied woodpecker at one of my bird feeders. I’ve ordered a trap.

    My question: is dispatching them using the cervical dislocation method the easiest way to humanely kill them? I’ve read the co2 chamber method takes time and I don’t want to prolong the experience.

    Curious about post-PhD job prospects worldwide in the field of biological invasion ?

    Having just completed my PhD in India, where my research focused on invasive alien fishes, my chapters involving Species Distribution Modeling (SDM), molecular biology (mt & microsat), and a policy-oriented approach. Now, besides considering postdoc i am wondering what sort of job opp available globally!

    What tool would you recommend for girdling Bradford pear trees?

    There are some Bradford pears in my area that are too big to cut down. Even so, I want them dead. I was thinking of stripping a ring of bark from the trunk, then poisoning with tordon. What tool would do best? I've seen girdling knives that make a tiny strip & are namely for little trees/branches, & I've seen draw knives for stripping bark from logs. Is there another tool I'm unaware of?

    What is spotted lanternfly's role and impact in its native range?

    Does anyone know of any good sources about the role SLF plays in its native range? All I get from google is a bunch of university extension pages about their invasive ecology, but I'm specifically interested in their native ecology.

    What is Happening to my Himilayan Blackberry Plants?

    Noticed that many of the blackberry plants on my property are dying recently. Don’t get me wrong, this is a wonderful development, but curious as to why it would be happening.

    Best of my knowledge no one has sprayed any herbicides on them and other leafy bushes in same vicinity are spared. Plants look like the picture then go fully brown and dead on a few weeks.

    Ideas?
