Stocking small brook trout streams is obviously a problem, but I think another issue we have in PA is we have no medium to large streams/rivers that are brook trout streams without stocked trout or wild nonnative trout. Seeing some of the streams in the video the OP posted in WV is awesome. We have nothing like that. To be fair, I don't know if those streams are stocked or have nonnative fish present, but I wouldn't be surprised if they're allopatric brook trout streams, either.
I truly believe the number one issue in PA is nonnative trout. The reason I say that is because all of the other negative impacts to brook trout are being addressed are openly discussed and aren't controversial. Nonnative trout are the elephant in the room.
I think this map (from EBTJV) tells that story.

Then compare that to this (my map):

Notably, the area in the eastern Adirondacks, which is blue on the EBTJV map, is where NY DEC conducted hundreds of reclamations. Aside from Vermont (another state lagging behind other states in terms of brook trout protections) PA has the widest distribution of sympatric populations.
Even comparing WV and PA in terms of stocking shows how much more stocking PA does.

It seems like every medium sized stream in PA is stocked. All the small streams that get stocked or have wild nonnative trout or are stocked privately or by co-op nurseries isn't represented in that map. That's just PFBC stocking.
Compared to WV (green lines are stocked).

The problem with PA now is we've ignored this issue for so long that in order to create a special management area for brook trout would mean removal would be required. Best case scenario they could establish aggressive angling regulations like no closed season and no daily limit on nonnative trout, but I doubt that would result in any meaningful reduction in nonnative trout. Maybe if it was combined with annual manual removals. There's no appetite for any of this in PA so it will likely never happen.
I personally think these special management areas serve as an educational tool more than anything. They also promote the species to anglers. Referencing the recent letter from the outgoing steering committee chair, "Many states have designated high quality eastern brook trout fisheries that have special management regulations to protect these fish, and to improve and promote recreational fishing opportunities..." Pennsylvania isn't included in "many". In fact, we're 1 of 4 states that have no brook trout management area.
I don't think nonnative trout are the biggest cause for the lack of allopatric brook trout populations, but our avoidance of even admitting it's an issue is going to continue to become a bigger and bigger problem. Again, in my opinion, it's the biggest issue facing brook trout in Pennsylvania, not because nonnative fish are the biggest threat, but because nobody is addressing it at all.
This issue was listed in the trout management plan:
I can say that in the three years, since that plan was published, the only thing that has occurred relative to this issue is a meeting was held last year to discuss designing a study. That shows this issue has no priority at PFBC.
I know this is a controversial subject in angling communities. That just further reinforces how far off the rails we are.
