Trees that go bare in winter, and the ones that don’t

← All field notes

In a Long Watch winter the wood itself should read as winter. A few trees stand bare, their branches open to a low sky; the pines beside them hold their needles as though the cold were someone else’s problem. Getting the world to tell those two kinds of tree apart, and to undress only the first, took a day and a couple of wrong turns.

The world had known how to do this once. Back when its whole plant life was a single oak over a field of grass, that oak already thinned to a bare trunk each autumn and leafed out again in spring — the first time the turning year showed on screen at all, back when the leaves first turned. Since then the roster has grown past twenty kinds of plant, and every one was resculpted from a shared stand-in shape into a voxel model of its own, a crown carved from the same cubes as the hills it stands on. Somewhere in that resculpt the trees forgot how to shed. The new models were lovely, and stuck: full crowns, all twelve months of the year.

The trees that shed, and the trees that don’t

Real woods sort into two answers here. A deciduous tree, an oak or a birch, lets its leaves go when the cold comes and stands bare until spring. An evergreen like a pine keeps its needles the year round and barely marks the season in its shape. The Long Watch now holds five kinds of canopy tree, and only two of them, the oak and a hardy birch, are the sort that go all the way bare. The other three stay green straight through the snow.

So the rule that thins a crown had to learn to ask one thing before it did anything: is this a tree that sheds? Only on a yes does winter strip it back. Obvious enough, written down. The first version never asked.

It thinned every tree the same way, so when winter came the pines undressed right alongside the oaks. A pine stripped of its needles isn’t a wintering tree, it’s a dead pole; a whole evergreen stand went to grey spikes in the snow, looking less like a forest holding its breath through the cold than one that had burned. The fix was the question above: shed only from the species built for it, and leave the evergreens their coats.

There is a floor under the rule as well. A blade of grass or a fern is all leaf and no trunk, and stripping one leaves nothing standing where it stood — the plant would blink out of the world each winter and back each spring. So only trees, the ones with a trunk to stand bare afterward, shed at all. The low plants keep their shape the year round, whatever the season does to their colour.

How a crown comes apart

There’s a second thing to get wrong even once you’re shedding only the right trees, and it lives in the order the leaves come off. A tree doesn’t jump from full to bare in one step. It thins across the back half of the year, and a half-thinned tree still has to read as a tree the whole way down.

Our first pass shed the crown from the top down: clear the highest leaves first, then the next layer, and on toward the branches. Tidy in principle. On screen it planed every tree into a flat cap — a mushroom hovering over a trunk, then a thinner mushroom, then nothing. No real tree loses its top and keeps its middle.

The repair was to peel the foliage from the centre of the crown outward instead. Leaves come away from the middle first, so the canopy hollows and opens as it thins, holding a ragged, believable outline all the way to bare branches. Caught partway, a tree looks like an autumn tree partway through losing its leaves, which is all it ever was.

A bare oak and a green pine standing side by side in the snow say more about the month than any colour could.

What a winter looks like now

The same day’s work reached the dead trees too. When a tree dies it no longer snaps back to a placeholder block; it comes apart where it stands, from a bare snag to a fallen log to a flat scatter of litter, each stage a real shape on the ground. What that long unmaking gives back to the soil beneath it is older ground we’ve walked before.

The trees are the same trees; only their winters got honest. A valley dates itself by its branches now — the evergreens standing dark and steady while the oaks and birches go to bare wickerwork and leaf back green a season later. Long winters were always meant to feel long. Now they look it.
