Why we count what grows along the Sana

There's a kind of work by the river that looks dull from the outside. Someone crouches by the water, looks at a leaf, photographs it, writes down a name and a date, and moves on to the next one. No adrenaline, no cover photo in it. And yet that crouch is one of the most important things done around the Sana, and here is why.

To protect something, you first have to know it exists. That sounds obvious, but in practice hardly anyone knows what actually grows and lives on the stretch of bank they pass every day. The large and familiar things are known. The small ones are not: a plant that appears only on wet karst rock, a tiny water invertebrate that tolerates only clean, cold water, a bird that nests exactly here and nowhere three hundred metres on. All of it exists quietly and unrecorded. Until it's lost.

And it's lost without anyone noticing. A river that looks the same for years is in fact changing constantly. A drought drops the level, a plant someone carried in by accident starts crowding out the natives, something shifts upstream and is felt below only years later. By the time a change is visible to the eye, it's usually too late to ask what things were like before. Unless someone wrote down what things were like before.

That's the point where a list stops being paperwork. A species list made today isn't a list. It's evidence. In ten years, when someone asks whether something has disappeared here, or whether something has turned up that shouldn't have, that piece of paper is the only thing that can answer. Without it we have only memory, and memory is easily flattened by the sentence "it was always like this."

The springs of the Sana are protected precisely because they are not ordinary. But protection on paper guards nothing on its own. What guards it is constant watching, regular visits, and people who notice when something goes wrong while it can still be put right. A census is a tool of that kind of care. It turns "it seems to me there used to be more of those little frogs" into a figure that means something.

And this isn't work for specialists alone. Far from it. The person who passes the river every day sees changes a once a year visitor never will. A photo of a flower with a date and a location, a note of where something appeared or vanished, all of it has value if it's gathered in one place. Protecting a river isn't a set of grand gestures once a year. It's the sum of small, stubborn, seemingly dull records.

So we count. Not because we love lists, but because a list is the only way that, a few years from now, we'll have the right to say what was here, and be able to prove it.
