If you want to help reforestation, it's important to know about a process called ecological succession. This is how nature does it.
The plants most people think of as weeds are very important in this. Botanically, they're known as pioneer species. They're tough, tenacious, and will grow even in unforgiving places.
Pioneers lay the groundwork for larger plants to gradually take over, eventually making a comfortable environment for climax species, like forest trees.
They need anchors (so a reasonable depth and maybe a particular kind of bottom? Thick enough sludge?) and adequate nutrients in the water. And they throw off bits all the time, so if you have habitable conditions kelp has probably already grown there.
Half of it's just opening your eyes to the world.
The other half is when someone like yourself says "look at this".
@InvaderXan For some reason this lesson from like 6th grade biology really stuck in my head. I think it's really cool!
When I came to Mississippi I felt like something was wrong with their forests and they felt unnatural. Then I found out that much of Mississippi has been clear cut for generations with trees being replanted in regular patterns. This messes up the normal processes of ecological succession
I know what you mean. Forests which have been artificially planted with no thought about how this happens naturally, nearly always feel... not quite right.
@InvaderXan we gotta talk about how colonization interacts with this. in australia, aboriginal people have been using fire management to create patch mosaic landscapes for centuries or millennia. the model of "natural succession" here is often a european construct foisted on a huge diversity of ecosystems. "natural succession farming" MUST be tailored to the landscape to be worthwhile
thank u for writing this up! it's great
This is an important thing to consider. And I must confess, I don't know so much about Australia but, let's be honest, a ton of damage was done by Europeans being clueless about the local ecosystems.
I feel like it is, of course, vital to know the land you're trying to help. And no one knows the land better than indigenous people who've been caring for it for thousands of years!
Pretty much. And not just an early state, but a monoculture. In Northern Europe, for instance, two of the most common lawn "weeds" are dandelions and clovers – two excellent pioneer species. Dandelions have deep roots to draw up nutrients from underground, and clovers fix nitrogen, enriching the soil.
@InvaderXan I fell several large trees three years ago, about 50-60 of them due to the beetle borer/fungus. They made some really nice boards. Best thing I did was move the same tree nears the stumps. Fast forward and the EWP are nearly 5ft tall and strong.
@InvaderXan That's a really handy diagram.
I work for a conservation charity. When I started I found it surprising how often we're actually working against succession, because if we let everything turn to forest we'd lose the other habitats, and the species that live in them.
Oh, that's interesting. Yes, I guess you need to pay very careful attention to whatever environment is already in place. I was approaching this from the perspective of restoring forests which have been destroyed, and completely missed that nuance!
