Trophic Cascade

 

After the reintroduction of gray wolves

to Yellowstone and, as anticipated, their culling

of deer, trees grew beyond the deer stunt

of the mid century. In their up reach

songbirds nested, who scattered

seed for underbrush, and in that cover

warrened snowshoe hare. Weasel and water shrew

returned, also vole, and came soon hawk

and falcon, bald eagle, kestrel, and with them

hawk shadow, falcon shadow. Eagle shade

and kestrel shade haunted newly-berried

runnels where deer no longer rummaged, cautious

as they were, now, of being surprised by wolves. Berries

brought bear, while undergrowth and willows, growing

now right down to the river, brought beavers,

who dam. Muskrats came to the dams, and tadpoles.

Came, too, the night song of the fathers

of tadpoles. With water striders, the dark

gray American dipper bobbed in fresh pools

of the river, and fish stayed, and the bear, who

fished, also culled deer fawns and to their kill scraps

came vulture and coyote, long gone in the region

until now, and their scat scattered seed, and more

trees, brush, and berries grew up along the river

that had run straight and so flooded but thus dammed,

compelled to meander, is less prone to overrun. Don’t

you tell me this is not the same as my story. All this

life born from one hungry animal, this whole,

new landscape, the course of the river changed,

I know this. I reintroduced myself to myself, this time

a mother. After which, nothing was ever the same.
