It’s surprising how many ecological transformations are possible given a salt lake bed and a patch of common reed to begin with. So many in fact that it’s taken a few days of sorting through all of my artist’s impressions to pick out a series that’s not merely arbitrary, but seems to comply with my basic idea of how reforestation works, but this is more like a regrasslandestation. Here we see what is basically the original salt lake bed, except I’ve cleared some haze out from the background to improve the view. You can almost see the low mountain range on the horizon.

The next step involved planting a nice green lawn in the salt bed.

Salt lake with lawn

I’m not sure what species of grass it was, but it clearly thrived on the saline conditions; it even outcompeted the common reed grass.


It strikes me now as I weigh up the pros and cons of this transformation that where there were at least three biomes before (mountain range, salt lake bed, and common reed patch) there is only one biome now (if you don’t include the sky). So there is nowhere for two communities to meet and integrate as per the definition of an ecotone, unless you include the sky.

The obvious thing to do here is to define the sky as a biome, thus permitting whatever community happens to be there to transact with the one on the overgrown lawn. This in turn leads one to wonder what kind of transactions occur between the other side of the sky, and, say, the surface of the moon. The result of this kind of wondering I found turns out to be mostly very silly, but I did start to wonder about how one would go about terraforming another planet to make it suitable for life as we know it on Earth, and that’s not so silly to wonder about. For instance, can the terraforming process manufacture a wide range of ecotones where biomes from different communities can meet, integrate, and produce edge effects? I’ve not seen any such consideration given to this question in the literature of terraforming. And if it can be done, how many salt lakes should there be compared to lawns and common reed patches? Which countries on Earth will the salt lakes and their vegetation be introduced from?

  1. the literature of terraforming, that is likely in a geological library somewhere:). it has both poetic and a science kind of feel, it’s really great!
