Yeah, we had good rain here in the north. We became the refuge for those running from the southern fires.
The heat melted the glass windows of the chicken coop at the ranch just before the whole thing went up in smoke.
Wildfires are so natural here that the pines are serotinous.
Seed cones for regeneration will not open without the heat from fires. They don't open.
So, you need to comprehend that this whole place, in patches, burns to the ground every 70-100 years.
Don't panic. This is normal.
The only really strange place is The Ancient Forest. A region in a "lightning shadow" where weather conditions never generate thunder & lightning storms.
From the 14C dating in soil pits, the place has not experienced fire for more than 4,000 years.
If you think you know what the climax seral stage vegetation is in the ICH Biogeoclimatic zone is here, be my guest.
Birch is not replaced in any seral stage in western Canada. Water and nutrient levels in recently glaciated soils spoil your suggested sequence.
Spruce for the most part, cannot replace birch for bio geoclimatic reasons. If anything, spruce replaces pines replaces alders and aspens
but water retention and shade tolerance in nutrient-poor glacial soils are determining factors.
As I said, Angie travels from BC to Manitoba for birch bark for her art. Birch bark is not in short supply.
Even for flint, copper and abalone shell, those things are not available everywhere.
On Isle Royale for example, there is a lump of copper, biger than a grand piano. Big deal.
I can buy copper nodules dredged from west coast rivers.
Somehow, the city scrap metal yards are so much closer!
