disturbance:succession

in Environment by

Nearly illegible, these boreal forests.
Crabbed hieroglyphs in charcoal deposits
serve as proxy as we core and trace cold lakescapes
for evident losses of the steady state.

Twice per human lifetime, a scorching rash
of budworms deadwoods every spruce
and true fir in the regular stands.
Blooms of urgent moths die heaped in carparks

and in waxy drifts across Quebec lakes,
the membranes and sockets drying
and releasing wing scales as they go, to coalesce
in shimmering astral belts across

the water’s skin and lastly down
to where their submission is logged in mud
and extracted from every inch
of the long deposition.

Sorted with a finer mesh,
the old fragments come up broken,
crumpled or covered,
and we can just make out enough

of the whole scales—the delicate leavings
of a countable species—to be certain
of the outbreak and confirm
the unhappy abundance.
