Okay, here we go. This is a quick read since I'm going to address some other stuff on page 4 as well. Given that 354 is a blood forest kinda thing, I'm guessing it's the first tab. Here are my thoughts:
So uh… right from the beginning, you've got some pretty shaky tone and wording. "SCP-XXXX is to be isolated via a 7m tall electrified fence, referred to as Site-XXXX-1" is confusing because it's not clear what the entity is being isolated from, what kind of perimeter the fence is supposed to be setting, or why the fence needs to be both taller than a two-story building and electrified. That's a heck of a lot of electrified fence. Also, why is the fence itself designated Site-XXXX-1? Why the XXXX-1? Why does the building inside the boundary of the fence get designated as a separate Site? It's also confusing to think about a forest breaching containment.
I recommend reading this guide on containment to get a feel for how to write more logical, resource-conserving procedures.
The description is similarly clumsily-worded. For example:
SCP-XXXX is a large section of forest located in the northern part of Alaska, nearby the Canadian border. Its epicenter is located at ██, ███, ██, and spreads up to 5m every three months. At the current time of writing, SCP-XXXX spans 150m2 from its epicenter to its border.
You can probably be more specific than "northern part of Alaska". Also, it'd be "near" the Canadian border, though if I recall my map correctly, Canada is closer to Alaska's southeast border than the north. Furthermore, the way the epicenter is described, it's confusing because seems like the forest center itself spreads, which is kind of hard to visualize, especially since at that point it hasn't even been established how this thing is anomalous. Forests typically grow. That's normal. Also, if the epicenter itself spreads, then why hasn't the area of the epicenter itself gotten bigger? I think you mean to say that the area of SCP-XXXX itself spreads, not just the epicenter.
The rest of the article is similarly strewn with confusing, unwieldy language like that.
Ultimately though… this is kind of bland. It's a dangerous forest and there's blood involved for… some reason. Also, I'm kind of sick of the whole "also and then staff went in but SOMETHING TERRIBLE HAPPENED TO THEM!!" addition at the end, with the "a containment team was sent to the forest's epicenter, where the team [DATA REDACTED]" bit. Did they have a mad dance party? I recommend reading over this guide on interesting expungment for some tips. Same goes for the excessive explanation of just how violent this thing can get—doesn't matter if you just say it hurts people or you mention the "violent amputation". It's still fundamentally just a thing that hurts people. And we have a lot of that already.
I also don't see why there was so much trouble happening with the plants. Just send a couple drones to dump an herbicide or some sort of chemical growth stunter thing.
Did you get this concept checked in Ideas and Brainstorming before drafting this?
That is where the idea came from, actually. Here's the thread.
Hm… it doesn't look like an experienced author gave you a "yeah, this is ready to draft" go-ahead. Granted, it's not a requirement, but it's generally a very good sign if you have it. I personally feel like the conceptualization could be a lot stronger here.
