For more context here, this is an image (from a few years ago) of what I mean by forest dispersing flow. The channel steepens just downstream of this forest (second image) - that looks to me like a headcut arrested simply by obstruction-forced widening upstream.

They do! Holy cow - never even occurred to me. Would take some absolutely beastly giant beaver to move these logs, though - I don't think even Casteroides ever got that strong, haha.

I got so sucked into this yesterday that I ended up editing the Wikipedia page on avulsions to correct the misunderstandings that avulsions are: 1) only full diversion from one channel to another (if so, how could multi-thread channels even exist?), and 2) driven by differences in slope.

Here's another one. Side channels in the floodplain have been there, and much shorter than the mainstem, for close to 30 years (inc. a 50-yr flood). Wood plays a big role here, but so does the vigorous floodplain forest, which disperses flow and inhibits headcuts that would otherwise drive avulsion.

Yes, so good! If the comment's purpose is really to convince the authors to make the suggested change, then making that comment constructive and kind is the most effective way to accomplish that.

But is 90% for seed planting, or planting starts? That sounds like it must be for starts - I'd think seeding, even by hand, would have at least a little bit lower survival rate.

Thanks - both are great companies, but AFAIK only have an employee ownership program, not a cooperative structure. Employees may receive more of their labor value as compensation, they do not have much control over it (i.e., governance is still much more hierarchical than most cooperatives).
