Great responses! I'm actually surprised people are managing such meaningful comment on just two pictures showing a lapse of time.
I basically shared it because the natural transition was a surprise for me and inspirational.
Here, among permies, we probably recognise the importance of observation. Ben Waimata sees very different things when he looks around than I do, and needs to learn from his own observations rather than mine. So the pictures I posted are relatively meaningless to others when they don't live in this area.
And I don't really know what to learn from what I see as well. Roberto gives a solid explanation of what's going on; the strength of a well established perennial system of native vegetation. And yes, also the speed of growth belonging to a short season climate, as Ben noted. I do feel strengthened in some
permaculture principles that I've embraced; especially the one about having a good base of perennials.
On my allotment the perennials still need to get established more. It takes time, years, to get from crap compacted clay to airy nutritious Hügelbeets covered with a base of thriving perennials. I won't be too harsh on myself and will allow the time.
About the pictures I like to remark there's no creek; that word means a naturally flowing stream, right? I live in The Netherlands, already at sea level, so no natural creeks anymore. Narrow lines of
water here are man-dug. Canals form the borders between plots and are used drain water away from the
land, into the sea with the aid of mills and turbines. It doesn't make much difference to what we're on about here, but I have to admit the word 'creek' irked me a bit. Also this is not my property, I'm registered homeless even, although I do have this place to stay and I hope to be able to stay here for longer. Otherwise there's not much point in spending much
energy in it, although I have already done so. On the waterside you see I removed willow, and put in some edibles like rhubarb, lettuce, courgette, cherry tomato and a berry bush. Also useful plants for insects like comfrey, lupin and poached egg plant. Nothing that would alter the character of the place too much, I wouldn't want it to look like an allotment plot, although probably quite a lot of edibles can be put in without that happening. I'm curious to see where it can go.
I'll leave you with a view on an allotment plot neighbouring mine. It hasn't been tended for long, nothing was put in this season, but rather than an unsightly mess of weeds, it has actually turned into a pleasing display of self seeded flowering kale, poached egg plant and some long grasses. Sorry for my bicycle crate on the left, and my neighbour's garden is behind that; top half of the picture:
