The grass died standing. That’s the thing about spartina — it doesn’t lie down. Through December, January, February, it holds its posture even as the green bleeds out of it, even as the stalks go pale and then darker, the color of old rope or undyed linen, a warm ash. By March it’s been through three months of freezing and thaw, bent by storm after storm, and still it leans just slightly windward like something waiting. The marsh looks dead from the road. You have to be in it to know it isn’t.
The smell arrives before anything else. Hydrogen sulfide from the anaerobic mud, the sulfur-sweet rot of detritus, salt so thick it’s almost taste. This is the smell of something working — the bacteria in the sediment breaking down last summer’s growth, cycling nitrogen, releasing what the new season will need. The marsh stinks because it’s alive in ways that are easy to miss. You smell it and think: decay. But it’s more like digestion.
The tidal creek runs through it the color of strong tea, tannins from the upland marshes staining the water brown. At ebb tide the mud walls rise two feet on either side, scored with the claw marks of herons and the small paired prints of something that came in the night and left before the tide came back to erase it. The creek bends with a logic that took centuries to develop — each bend creating a slower current on the inside where sediment drops, a faster current on the outside where it scours, the channel migrating imperceptibly year by year. Everything here is moving, just slowly enough to look still.
A pair of black ducks lift from the creek mouth and wheel north, dropping again fifty yards upstream with a splash that sounds too loud for the space. They’ve been here all winter. They’ll stay through summer, nest somewhere in the high marsh above the tide line, raise young that will learn to filter mussels and amphipods from the same water their parents filtered. The marsh feeds them. They feed the osprey that will arrive in April — already on their way from South America, riding the thermal gradient north — who will take them occasionally, carrying them off to the snag trees at the marsh edge with the same efficiency the marsh itself brings to everything.
Efficiency. That’s the wrong word but also not entirely wrong. The marsh doesn’t waste. The dead grass decomposes into detritus which feeds invertebrates which feed fish which feed birds. The sediment traps and builds, the peat accumulates at about a millimeter a year, the marsh surface slowly rises to match the rising sea, has been rising to match it since the last ice age, an incremental keeping pace that is now being outrun for the first time in twelve thousand years. The math on that is not good. But the marsh doesn’t do the math. It just grows.
The ice is gone from the creek edges. It was there two weeks ago — shelf ice, gray-white, forming at the high water line and receding as the tide rose, a daily freezing and melting that lasted through January and into February. Now the water moves free on both sides. The mud at the edges is beginning to soften. Somewhere under the dead grass, the spartina rhizomes are alive — they’ve been alive all winter, dormant, waiting. Within six weeks the first green shoots will push through. By June the marsh will be waist-high and impossible to walk through without getting your boots sucked off.
A great blue heron lands thirty feet away, setting down with an improbability — something that size shouldn’t be able to land that delicately — folding its wings with a slight shrug, composing itself into stillness almost immediately. It watches the water. The patience is not patience in the way we mean patience — it’s not enduring something it would rather not endure. It’s simply attending. The heron is all attention. The water moves. A mummichog comes into the shallows, drawn by whatever mummichogs are drawn by. The heron moves its head perhaps a centimeter. Then it’s still again.
Then it strikes, and comes up with the fish, and tilts its head back, and swallows.
Nothing in the marsh is symbolic. Nothing stands for anything else. The heron is not solitude or patience or the predatory sublime. It’s a bird that needs to eat a certain number of calories a day to sustain a body that weighs five pounds and stands four feet tall on legs that look like they were designed by someone who had only heard birds described and never seen one. It came here because there are fish here. The fish are here because the marsh is here. The marsh is here because ten thousand years ago the sea rose into this particular low ground and the spartina moved in behind it.
The wind comes off the water carrying the smell of the open Atlantic, cold still, carrying February in it. The dead grass moves. The heron does not.
