Two possibilities. Get some "deer corn" from a feed store and place it where they will do no damage. My grand daughters have a tree house and I built bird and squirrel feeders on nearby trees so they could feel like they were out of the city. They also put out yarn and cloth strips for the birds to put into their nests but I did see squirels carrying this also. If this fails then go to a feed store or Home depot in the gardening section with the chemicals you will find large green or yellow cylinders about 1 inch in diameter and 1.5 inches long with a hole through the middle just nail these about 4 ft off the ground and replace when gone until the squirrel population is controlled. Last year I had a bumper crop I counted 8 to 12 in my trees several times and 5 was the normal number. They dug up everything within 3 ft of the trunks. After a week of the spools I was down to 3 squirrels and I could tolerate the small amount of damage that they did. Put the spools where any dogs will not be able to get to any remains, at some point small pieces will fall to the ground but these are usually eaten by the squirrels. Bill

HU bunch of numbers, I am having a hard time understanding why you signed up only to post this misspelled and hard to read diatribe on a thread that has had no activity for 3 years! First oaks.......and many other tree species........are wind pollinated. The presence, or lack, of acorns has nothing to do with any perceived decline in insects! And there is no lack of birds in my garden and the surrounding woods - finches, woodpeckers and sapsuckers, robins, chickadees, hummingbirds, blue jays, flocks of starlings, crows, eagles....even owls. The beach is only a block away and at low tide the flats and sandbars are covered with herons, gulls and cormorants. Local parks are plagued by Canadian geese. Pigeons perch on phone wires and businesses put up defensive measures to keep them from roosting in the eaves and soiling walks and entryways. Birds........and their food sources........are everywhere. Let's not get too carried away!!

The arborist who treated my trees here in the dfw area commented they are really going after the live oaks this year. My most afffected were mesquite, Mexican White Oak and Cedar Elm. But they went after Chinese Pistache, Pecan, Japanese Blueberry, Bur oak and Chinquapin as well. Mirrors and reflective objects did nothing to stop the ones attacking my trees. Nor did and noxious spray. He said the trees are stressed and have increased the sugar production due to the stress and the woodpeckers sense it and go after those trees under the most stress.

Norbert, that map of your hardiness zones IS CONFUSING TO ME. I am likely wrong, But, I can't help but wonder how HUNGARY is zone 7a and zone 7b, BUT, everyone around them seems to be zone 6b, and possibly zone 6a in some places. Norbert, I am really only able to grow the Quartz mountain Live oak. AND, it is ONLY QMLO trees that have trunk girths of about 3/4 of an inch or more, NOT, those little whips with tiny little trunks that are way smaller than measurement worth measuring. This QMLO I have, It is Extra hardy, and only recently my area has been getting some REALLY hot summers. Is it from global warming? Maybe, or maybe not. BUT, Norbert, IF you really want to grow a Evergreen oak, the Hybrid of Q. Robur ( English oak) and the Q. Ilex ( Evergreen oak) ummmm..... yeah, I can't remember the name of that hybrid oak. I had gotten one to plant about 4 years ago, kinda illegally, BUT, it had died here in my zone 6a winter. Okay, it was called the "Turner's oak". Norbert, if you are really in a a zone 7a area. AND, you can get a "Turners oak" or even a Q. ILEX, Q. ILEX is an evergreen oak that can do great in an area that doesn't have a ton of sunlight in summer and heat. REALLY, the Q. ILex is likely going to be MUCH easier to find in Europe at nurseries to plant. And it IS an Evergreen oak, and it is zone 7a hardy. It is really impressive in old age. NOT, LIve oak tree impressive, BUT, it is a nice tree in old age. I replied to your message Norbert. BTW Norbert, I have my big yard in thanks to my family, I could never afford to buy this OVER 3 ACRES of nice rural property. Since my dad passed away, I am the 1 who cuts the grass and tries to fight back the weeds, and cuts around all of those damned trees I planted. MY dad was super pissed about all of my trees, I had made big mulch circles around them, so it would be easier for him. I miss my dad, he passed away, BUT, ANYWAY, I have been using "GLYPHOSATE" or "GLYPHOSPHATE" which of the 2 means "I"VE BEEN USING "ROUNDUP", and I am hoping that "Glyphosate" or however you say it doesn't prove to be a big cause of cancer, because #1 I use it alot, I don't want cancer #2 It does well to stop weeds from taking over places #3 It is great in Lue of burning weeds to make for garden plots.
