I had some like that, along the river boundary. Slowly got rid of them especially the wire gaps. I hated them, from the days of my youth.
Trees worked ok ....... until a tree fell in the river and took the whole fence with it.
(A minor point of contention (no pun intended)
The barbed wire in the pictures I posted is 4pt, not 2 pt. Pretty sure it came from a local place called McCoys that is also a Preifert distributor. The net wire tho, probably came from TSC as I remember when the original fence was built b-i-l had to drive to the next town to get some as there wasn't a TSC in Cleveland at the time and McCoys he said was too expensive. The company that built the original fence didn't bother calling about underground stuff and they drilled right thru a 6" rural co-op water line that served the whole area, and they had to shut it off for several miles. )
I'm not a fan of the barbed wire they used. Low carbon and it got loose everywhere and sagged after a couple of years. Both my B-I-Ls refused to use gaucho type HT barbed wire.
