that sucks, but sadly, its just a bear trying to live, food is food to them, they could care less if you don;'t want them to eat it?
live where bears are, and you have to expect some damage at times
here in PA< on my one farm, if I fenced tree's like that, the deer would push them right over too, and do damage like that too!
lost so many tree's on the one farm I gave up, never got to the size, a bear would damage, darn deer wouldn't let them get there ??
better fencing is about all I could suggest, that or adding some power to the fence, bears really DON"T like getting zapped
might help you, they sell decent solar powered units too if remote ?
you might also do well with a few cheap harbor freight wire less alarms, what's nice about them is they all trip the same , so if you have one set up any where it will trigger all the alarms you have
so you can place a base in a few rooms or ? and get to hear it go off, there like 10 bucks or less on sale
Other wise, its just part if living in bear area's
you have to think the bears were there before you and there only trying to live, food is food to them, easier is always better too/
I will never blame a bear for doing damage, its only being what it is
I have LOTS of them here, and to be honest DEER are way more problem for me, at the one farm I couldn't get a apple tree to grow, deer would eat them to the ground or every limb on them, spent a small fortune truing, and they will shove a fence down like your's too
go taller or wider around the tree, and they will jump over a 8 ft fence and get in side ?? I gave up on fruit tree's there,
bears there never got a chance to do damage LOL
AT my hunting place, I have a TON of bears, almost daily at this time of yr, most at once has been 9
and in 30+ yrs of having the place, never a lick of damage , minus a small branch or so getting busted
but I think its in part to a LOT of food, they tend to stay out of the tree's and eat what's on the ground, as the tree's there normally produce a ton of apples, and by the time there all gone, many bears have denned up for winter!
But there on the deck there all the time, to date ONLY one female bear has figured out my bird feeder pulley system, and she has never even damaged it to open it, I think she is a VERY smart bear, or smarter than the rest! HAHA
but living in bear area's, you have to take the good with the bad, sorry?
