    the landscape vs natural succession. That's the debate here. The argument for it is that burning small patches increases biodiversity both for plants and animals. If done properly, it promotes native plants over invasives too. A lot of the grass out at Iceberg is nonnative, sheep forage deliberately planted and accidentally spread by early ranchers here. Burning would reduce those and favor the natives. When the Ndns did their burning, everything was "native" vegetation, so it was a matter of moving things around, and doing what nature does (forest fires, windstorms) but focused in certain places.

    The Ndns burned these bluff areas every 5-10 years. They also cultivated perennial plants, like the chocolate lily bulbs you mention, from what I have read.

    As you can tell, I favor modest controlled ecologically-informed burning. One of the realities we have to consider is that nothing is truly "natural" anymore, at least in these parts. People have been modifying the land for thousands of years. It becomes then a choice about what our modifications should be going forward. Doing it with knowledge can be an overall benefit to native wildlife and vegetation.

    Your USFS replanting situation up there - Old growth forest carbon is mostly in the trees, so if you cut timber and take it away, it's not surprising the remaining soil is infertile. Soil has to build up with rotted vegetation there before it will regrow vegetation successfully.

      We have a weird situation here with the nutrient cycle. Mostly it's sea to land, salmon runs, duck poop, bears and even deer who eat kelp during the hard times spread nutrients inland. 12 to 16 feet of rain washes it back down. The ice hasn't been gone here as long as one might think. I'm trying to find a link to Capt. Geo. Vancouver's chart of S.E. Alaska. Best as I can remember, Glacier bay isn't on it and the top 2/3rds of Lynn Canal is missing and missing something isn't what old George did a lot of. So, rock and peat fertilized by the sea.

      Baby trees grow real good, the young growth from natural reseeding is called "dog hair" because it's stem spacing is about the same.
