How that works out in practice is basically you as the owner of the tree have to document it's healthy each year. Then, if it falls and you can prove it was healthy you're fine. Hopefully neighbors insurance pays. If you didn't document the health of the tree, your neighbor can press charges and you (or your insurance) have to pay.
Unless negligence is involve (like an arborist being hired to condemn a tree), they’re generally considered and act of god. They’re the responsibility of the property they fall onto.
So, in the case of OP, the situation is unfortunate, but it’s on him to maintain his properties and his fence lines within his properties. It’s convenient the state has a fence along part of his property, but it’s not their responsibility to fix it for adjacent lots.
Practically you’re right of course, but they are probably technically responsible given the circumstances the poster laid out.
It would boil down to their degree of plausible deniability, ‘state priviledge’, and the specifics of the law and precedent in their state of course.
Good luck
I maintain timberland, a percent of dead and diseased trees are normal. It is highly unlikely, at least in the species I’m familiar with, that a tree will just fall over.
Evolution tends to select against that kind of thing.
Notably, parks get sued pretty frequently when trees drop limbs on people or trees fall on folks stuff, under exactly this principle. It works too.
See my comments above regarding some other factors that make it unlikely they could actually get damages (or it would be worthwhile even trying) in this case.
But it doesn’t remove the technical liability, most likely.
The most common claims that do actually get paid out is for things like public parks, street trees, etc.
Someone gets hit by a falling branch at a public park, or their car gets totaled by a falling tree, they tend to get sue happy.
This is correct when the trees are bordered on all sides by more trees. On the forest edge - which is what this seems to be - things tend to be different though and the occasional tree does fall due to storm, rock slides, wildlife activities, water erosion and more. Especially when the forest edge is relatively new, i.e. the bordering land has been cleared somewhere within the last 40-50 years these edge effects can be sizeable. Eventually the forest edge thins out once the larger trees have all fallen to create a more gradual progression from open land to forest and there will be fewer large trees to fall on bordering land.
I think I unintentionally brought Tree Law to HN.
Now that I think of this may be the first time that I've seen Tree Law on here.
We're only a hop, skip and a jump from getting some vigorous discussion about Bay area Tree Law now.

The Trees
Available on Hemispheres
Music: Geddy Lee and Alex Lifeson
Lyrics: Neil Peart
There is unrest in the Forest
There is trouble with the trees
For the Maples want more sunlight
And the Oaks ignore their pleas.
The trouble with the Maples
(And they’re quite convinced they’re right)
They say the Oaks are just too lofty
And they grab up all the light
But the Oaks can’t help their feelings
If they like the way they’re made
And they wonder why the Maples
Can’t be happy in their shade?
There is trouble in the Forest
And the creatures all have fled
As the Maples scream ‘Oppression!’
And the Oaks, just shake their heads
So the Maples formed a Union
And demanded equal rights
‘The Oaks are just too greedy
We will make them give us light’
Now there’s no more Oak oppression
For they passed a noble law
And the trees are all kept equal
By hatchet,
Axe,
And saw…What they are noting is the State is it’s own beast, and good luck getting it to do what you want.
This also is not a city type situation, where the density and value of something makes certain types of situations play out differently.
In the city, if a neighbor’s diseased tree falls on your house, you might have a legitimate legal claim, depending on the circumstances.
Your homeowners insurance will figure that out.
If one of the million random trees on state property falls on your fence? It doesn’t much matter what the law says, good luck.
Depending on the size of the tree and your home you might have enough to sell to the neighbors too.
I'm assuming the state doesn't come around asking for payment for their fallen trees.
I also wouldn't expect the fence to hold up well if the yard had anything that would attract deer or bears.
