Husqvarna 535 FBx Backpack Chainsaw - New Purchase and Initial Assembly
Since 2016 we have used this amazing tool for all kinds of thinning, cleaning, understory removal, and invasive species control. This tool has never been sold directly in the US; until about 2020, they were available in Canada, but then Husqvarna stopped importing to North America. For a couple years, a few Maine landowners bought them from a Swedish supplier but in 2022 they stopped carrying them. I had feared that they had gone out of production, but this is not true. They remain available from the following company:

Drill and Fill for Tree Injection - Spray Bottles (Husqvarna, Solo), Drills and Herbicide Mixing
Просмотров 3244 месяца назад
Drill and fill is a new alternative to the old tried-and-true “hack-and-squirt” method for injecting herbicide into a tree’s vascular system. Hack-and-squirt uses a small ax to make an incision into which the applicator injects a small dose of concentrated herbicide into each slit. Ergonomically it can be damaging to the user’s wrist and can lead to carpal tunnel problems. See another video on ...

Here Bob Seymour decides to cut off autumn olive stems that have invaded a log landing (last used in 2016) we are about to mow with our DR 26Pro 14 HP walk-behind brush mower. If we just mowed these off, they would resprout into many stems, making matters worse in the long run. So here Jess Leahy is snipping them off about a foot tall with pruning shears, spraying the stumps with a 25% glyphosa...
Gap-based restoration silviculture - beech control and enrichment planting white pine and red oak.
Просмотров 676Год назад
Bob Seymour describes a succession of silvicultural treatments made in a harvest gap created in a 2015 partial harvest. This stand was dominated by diseased beech; all merchantable trees were harvested, along with some very large bigtooth aspens and scattered UGS of maple and ash. In 2016, we planted bare-root white pine and red oak from the NH state nursery. Many oaks were eaten by deer, but a...
Planted American chestnut tree in Mariaville, Maine.

Ten years ago, we planted a few chestnut seedlings on our woodlot we call Black's Grove in Mariaville, Maine. The trees were planted in small gaps created during a harvest by the previous landowner. All are alive, but this one, in particular, is thriving, now nearly 30 feet tall and 4 inches dbh. We protected it from deer using a wire fence collar, and surrounded it with a 4-foot brush blanket ...

Thinning hardwood stump sprouts to a single stem using the Silky Big Boy - Black Cherry Example
Просмотров 692Год назад
Most hardwood species spout vigorously after harvesting, especially younger and smaller trees, forming multi-stem clumps that are not ideal from the standpoint of future timber quality. It is very simple to cut all but one stem, leaving a single tree to become a future crop tree. But how do you choose? Like a lot of content on this channel, there is much written about this topic, but precious l...
White Pine Weevil Control II - Treating Tall Trees
Просмотров 997Год назад
This is the fourth year we have been treating white pines planted in 2016 to protect them from attack by the white pine weevil (Pissodes strobi). These are the same trees featured in the first installment of this video filmed in 2020, which are now 10-15 feet tall and far more difficult to spray effectively. This year I discovered that Solo (the sprayer brand, made in Germany) makes a telescopi...

Pine Paradise Tree Farm - Ponsse Scorpion King Harvester Work Techniques in Dense White Pine Stand
Thanks for vid. I treated 150 white pines on my property this spring and only had (1)!!! Leader killed!! Many more the previous year. I need a bigger wand like you’ve got
Looking forward to seeing it in action. I reference your videos often. Thanks
I was a classmate of Mac Hunter at UMaine in the early 70s. The comment was made that he wasn’t a forester, but a wildlife ecologist. This is true, but students in the wildlife degree program in that era had a strong forestry course component. You could almost say forestry was a second area of specialty for the wildlife mgmt. majors. UMaine was a premier university to study forestry and wildlife mgmt,
Such a shame that beeches are being ravaged by bark disease all over New England. They were always one of my favorite trees and I have fond memories of being out in pure stands of beech that were absolutely magnificent. Of course it has enormous ecological importance too. One more tree species being removed from our forests.
What are you going to do when the trees are 10 feet tall? I have a small tree being attacked by them and I don’t know what to do.
See my other 2 videos about treating tall trees
Every time I did it this way they died.
thanks BOB
How did they take with the candles so far developed?
Bob, please wear a microphone so we can hear you.
Hi; is anyone having any luck finding one of these saws. They aren't available in Canada- so i'm told.
What insecticide works best?
Right ????
I love trees, and own a tree preserve, but not sure why this is video worthy. You act like this is unique. There are over a million American chestnut trees this size or smaller in the US alone. They just die from blight by age 15 or so. If this tree grows into a foot diameter or wider, then you'll have something. The trunk protectors are not some "Cadillac" thing. I do that for every tree I plant, lol.
I am so envious of the markets you folks have few lower value products(less desirable species). We largely can only sell red spruce with side deals for small amounts of hemlock or pine at sad prices no matter the quality. A clear pine or hemlock butt log is worth the same as a crocked top(sells by the ton). Unfortunately hemlock out competes most species growing on my woodlot(seriously) and we now have hemlock adelid within a mile of us. The idea of a timber sale....wishful thinking. The few contractors left all pretty all much cater to one big mill with little interest/ability to work on small private woodlots other than flatten them and walk away with no follow up. 0 market for any kind of pulp or hard wood logs. A sad place to be...kevin veinotte . Nova Scotia .
There are plenty of American Chestnuts in the Maryland mountains, it's just that few reach maturity before getting knocked back to the stump with blight. Still, there's a very good chance that there's a burr dropping specimen on a nearby ridge within pollinating distance. Good on you for helping to restore these magnificent trees.
OMG you supposed to keep the root dirt on it not pull em up dry roots, you ain't got but a few minutes to transfer those before you lose them
Oh shit ….
Agree, It may Still early enough there bursting with energy still not the best idea by far and not all will survive that's for sure! Definitely the wrong time for lifting or repotting white pine when any new growth has started! The candles at that length are ready for pruning not root Disruption! Hope he's got alot sphagnum and mycelium fungi for the root stress that's for sure! Amateurs man hurts everytime see a tree die!
Great to see you planting Bur oak Bob, I have planted some at my home from seed I collected in Dover-Foxcfroft. They are very slow growing trees and I find they prefer full sun. Good luck with this planting, I hope they do well!
Glad to see!!
I have never seen this and being a fan of pole saws anyway and suffering with my back nowadays I'm sold now just I have to find one in the UK.
See the description for two options. We just ordered one.
Starts at 1:52...
GOD bless U if those are PURE AC
Yay! I am glad you are doing this. Don’t believe the naysayers. I wish I had a cutting and could do the same. I remember the American Chestnuts near Philadelphia when growing up and loved them.
That's a good specimen , but the blight can live on other trees . Good luck and keep us posted !
A part of Maine I myself will never see, so thanks for taking me there. Love big trees/unique natural areas.
I was thinking of planting a few chestnut trees in the Dover Foxcroft area on my property. Where can I get some nuts(seeds), and tip and suggestions on growing would be most appreciated! Thanks, Mark
I was looking that up the other day and had no luck.
but why would you think it would escape because no other chestnuts are around? I think the blight affects oaks and other trees so the fungus is everywhere
Yes it lives on oaks and hickories but doesn't kill them. The tree in this video will die if it's not an American-Asian hybrid chestnut or one of the Darling genetically modified trees.
do they survive in Maine because of the colder winters? kills most of the blight so it has to restart all over the next warm season
Unfortunately oak trees act as a reservoir for the blight.
We're seeing Japanese knotweed, autumn olive and buckthorn here in southern NH. The knotweed is the worst though.
It’ll be interesting in the coming years to see what happens after beech leaf disease and EAB blows through.
We have those and the hemlock wooly adelgid here in southern NH. Black birch seems to be taking over the forests because deer leave it alone when they have oak and maple seedlings to eat.
what just one piece of paper will stop the deer?
Great video thank you.
Have you ever investigated the silver maple floodplain on the Pleasant River near KI? It's ethereal.
Yes, but only briefly on an AMC forestry tour this past May. Apparently silver maple was not valued for charcoal, so it was the only species not cut during the iron smelting era of the late 1800s. How interesting!
Hmm there are chestnut trees in my area that have leaves that look a lot like those but I dont know what type of chestnut trees they are but they are very old, at least 50 to 70 years old, but they are in the UK. what are the distinctive differences between the american chestnut tree and the european ? I looked up some information showing the leaf shapes and it fits the american or european but its still not clear to me.
there are many differences posted on the internet, but main thing is American Chestnuts used to grow tall! the tallest in the eastern forests and had large leaves and small chestnuts, wood was good for lumber since it grew so tall
In the UK you likely have Sweet (European) Chestnut (Castanea sativa). They aren't native. The Romans brought the first ones and Spain sent others from Galicia as a gift on the wedding of Catherine of Aragon to the Prince of Wales. Both sources host the endemic Hypovirus that confers limited protection from chestnut blight. Sweet chestnuts prefer to sprawl like oaks if they have the room. They have large (~1oz), low-fat nuts, often described as mealy. American chestnuts (Castanea dentata) tend to grow tall and straight which made them valuable as timber trees. The nuts are smaller than sweet chestnuts (1/4 to 3/4oz), higher in fat, with a sweet nutty taste. Asian chestnuts were bred as ornamental and orchard trees. They're dwarf, parasol-shaped trees usually with large nuts. The quality of Asian nuts is variable. Many Asian-American hybrids exist in North America as part of efforts to preserve the tree from extinction.
Any continuing ed opportunities online for this type of silvicultural system?
Yes, look at the webinars in my Webinar Playlist. Irregular shelterwood.
Thank you very much@@tmimotf
@@tmimotf Quick follow-up, how to you get continuing education credits after viewing? Thanks and excellent content
Very cool! Love seeing the old untouched forests
Thanks much for this video! My son has a property that he purchased and has about a 4 acre pine planting with some spruce mixed in. Earlier this summer i noticed 1 white pine that the terminal bud was wilting and i didn't know what was going on with the tree until today i seen the tell-tale signs of this little pest. Could you please give me the spelling of what you use and the correct mixture? Thank you so much! Ron
Watch the older weevil video from 2020, and at the end, you will find all the details. In brief, we use bifenthrin (Talstar) mixed in water.
Good work
I suspect that that planting thousands this way might allow natural selection to produce resistance. It couldn't hurt and at least if a few escape long enough to seed then it gives hope for nature to keep hope alive.
I'd like to get my daughter engaged in this. I believe she's very well suited for this
Congratulations! 🎉
I hope you can show us a 1 year update
Nice machine you got there I got AHM126 it's an older one but it works good keep on Cutting🎉🎉
Hi Bob just wondering if there is a blister rust problem there with them growing so tight I'm having a problem with my white pine regeneration in a red pine plantation I think because of too much shade I have to prune off infected branches throughout the year

Beautiful!
I wonder if you could rig up a second pointer more at eye level for the smaller logs. Possibly of heavy copper wire that could be bent out of the way for larger logs. Idk. Really good real time video. Ty
Thanks. I think the new Woodland Mills upgrade will do the job.
Can you share how Andy modified the crank to use drill motor?
Just remove the stock crank and attach the Makita, like it was a drill bit, using its on-board chuck key.
@@tmimotf thank you!
🙏 *promosm*
Looks like you are doing good with the machine and have it figured out. Have you ever thought of getting an automatic feeder so you don't have to push it along? One question. Why was the first cut so deep?
You need to vary the feed rate based on log size, species, etc so a fixed-rate feeder would not be optimal. Plus I don't mind the exercise. Yes, the first slab was a bit thick; I might have got a 4" board from it, but we were trying to finish and I didn't want to fool with any extra edging for such small boards.
@@tmimotf You can them them with variable speed settings but I get the exercise part, thanks.
