These crabs are the perfect storm for an invasive species, able to survive upwards of a week or more out of water, low salinity (allowing them to go further into estuaries), and water temperatures down to -1°C. They have decimated local Dungeness populations, destroy eelgrass habitat, and have done massive damage to the mussels and barnacles along with other bivalves in the area. They cannot be eradicated once established, but large scale trapping efforts can mitigate the impacts. In my area of northwestern Vancouver island they were trapped by the tens of thousands and their population has since gone down, but they’re very much still a threat to local species.

Earlier this year in April, I learned that we have Japanese Knotweed growing in the front of our house and before I knew how to manage it, I pulled and trimmed a bunch of it. After learning from my mistakes, I’ve been leaving it to grow and waiting to spray it with glysophosate.

My father in law sent some of his workers to do some yard clean up for us, and I made sure to tell them to leave it and I will be spraying it, and even though they said okay, I came out to it all gone.

The worker said he got all of the roots up but I know that is unlikely and now i will be dealing with the consequences, and now with it being mid-late August, that flowering window is likely gone and I don’t know what to do. The first picture is a month ago, and the second picture is today. Is there any hope left for me? This is Long Island, NY, for reference.

Was a brutal day on the fire line, tho.....

I was walking my property earlier today and while I have plenty of small walnut trees, I noticed something that looked out of place since this hill was bare last year. Rubbed the leaves and got that rancid peanut butter smell.

Could I use any old glyphosate or triclopyr spray since it's not too large and doesn't have any apparent suckers? I do have some desirable plants nearby, which leads me to understand that glyphosate is probably better.

22 invasive green iguanas we took out on our last hunt in SW Florida, including this 12-pound five and a half foot behemoth.

Green Iguanas are an invasive species in Florida. Their burrowing collapses and erodes sidewalks, canal banks, seawalls, and building foundations. They poop all over docks, decks, and in swimming pools. The poop carries salmonella which is dangerous to children and pets. Iguanas also eat native plants (including endangered species food sources) and compete with native wildlife like burrowing owls.

We humanely euthanize iguanas using high powered air rifles and single precise shots the head. I eat all of the iguanas I hunt, so they don’t go to waste.

Emptied my pond earlier this year and waiting for the gardener to come and fill it. Spotting this ToH growing 2 days ago. It rained this morning so I pulled it now hoping the damn ground would help a clean pull. Is it okay? What should I do next?

Would this scare you away from a dealership??

Haven’t seen this many in one place, these things have been taking over our dealership and just today got really bad! Here’s a video and if you have any advice on how to get rid of these things please leave a comment..

Book" by Menno Schilthuizen, pg. 156-157

I’ve read everywhere that you should spray with Glyphosate solution in late summer once Japanese Knotweed has flowered. Is to too soon to spray now? I want to get a few good sprays in before first frost.

See pics for what it looks like now, seems like buds are starting to form

for context, i do have several mature walnut trees on my property. struggling to identify if this is walnut, poison sumac, or TOH. I fear the worst!

If all goes well moving in this week, so should be an opportune time to hit whatever I need to with glyphosate / tricyclopyr.

Taking all the suggestions.

I did hack and squirt a month ago. One of the trees looks pretty yellow, other 2 are showing signs. Should i do another round of hack and squirt or do i have to wait until next year? Thanks
