Spiny softshells nesting through midsummer flow surge

July 21, 2026

are hauling out onto the Muskingum's exposed sandbars to lay eggs right now—observations from June through late July place them at the Zanesville riverfront and near Hanover Township, digging into gravel in the midsummer heat. These are among the most river-dependent reptiles in eastern North America: they breathe partly through their skin while buried in riverbed sand, spend nearly their entire lives in the current, and depend on open, unvegetated sandbars for nesting. Midsummer is their one brief window on land, and the timing this year has collided with a sharp flow surge—the river jumped from barely 17 cubic feet per second to nearly 2,800 in a matter of days—water powerful enough to inundate freshly laid nests before eggs can develop.

Their continued presence here, despite the watershed's long history of coal-era degradation and multiple permitted discharge facilities still operating out of compliance upstream, speaks to something resilient about this stretch. To find spiny softshells nesting means the riverbed still holds the clean sand and water clarity these turtles require. That such habitat has survived the industrial pressures of this region is a small but real sign that some portion of the river bottom remains intact.

Japanese Beetles (*Popillia japonica*) are at peak emergence now, their…

June 30, 2026

(Popillia japonica) are at peak emergence now, their metallic green bodies visible across the understory. These beetles have only six weeks as adults to feed and mate — a narrow window in which they skeletonize leaves on everything from wild grape to linden, leaving behind a lace-like skeleton of veins.The species arrived here just over a century ago, hitchhiking in imported bulbs around 1916, and has been spreading steadily ever since. The larvae develop in soil, and this spring's heavy runoff created ideal conditions — wet earth across the floodplain — for population numbers to surge. Records from the past two months show activity clustering in the region, and with the soil still moist from high discharge, juvenile populations may run higher than usual heading into next summer.

Muskingum at summer low exposes watershed stress

July 13, 2026

The Muskingum has dropped to a crawl. Current flow sits at just over 10 cubic feet per second — a stark contrast to the spring peak of 5,600 — and at such a trickle, the river loses the ability to dilute or recover from what the watershed sends downstream. Heat, excess nutrients, and dwindling oxygen become impossible to mask.Twenty-three of twenty-six water bodies within ten miles carry official impairment ratings, most commonly for depressed oxygen and nutrient loading. The Muskingum mainstem itself remains listed under federal standards. Low summer flows don't create these problems — they reveal them. In a season of drought and heat, a river running this thin is a mirror held up to the full weight of what industrial and agricultural land use leaves behind.

Wood thrushes hunt insects in summer breeding season

June 4, 2026

The woods near Blue Rock hold their breath in the longest light of summer. Eastern redbud leaves hang full and dark green, their heart shapes filtering the late afternoon sun into shifting patches on the forest floor. If you are walking these trails now, stop and listen. The air carries more than bird song.A wood thrush drops from a low branch twenty feet ahead, lands with both feet in the leaf litter, and begins to hunt. Its russet head turns sharply left, then right. The spotted breast remains perfectly still. This is how wood thrushes feed their young in summer: methodical, ground-level searches for the small invertebrates that emerge as temperatures rise and humidity climbs. The bird steps forward once, pauses, then strikes downward into the leaves. A beetle larva, perhaps, or a fly that lingered too long in the shade.Wood thrushes provision their nestlings with soft-bodied prey. Caterpillars make up the largest portion of their summer diet, followed by flies, beetles, and moth larvae. The birds hunt most actively in the two hours after dawn and again in late afternoon, when insects move through the understory and humidity draws invertebrates to the surface of the soil. A single pair feeding nestlings will capture hundreds of small prey items each day. They work the forest floor systematically, turning over leaves with their bills, probing soft soil, and gleaning insects from low vegetation. The hunting requires patience. A wood thrush will stand motionless for thirty seconds or more, head cocked, listening for the rustle of movement beneath the leaves.This summer hunting shapes the entire woodland ecosystem. Wood thrushes control populations of insects that would otherwise damage tree seedlings and understory plants. The caterpillars they capture are the same species that feed on redbud leaves, oak saplings, and native wildflowers. When wood thrushes remove these herbivorous insects, they release pressure on the plants that define this forest. The relationship runs deeper still. Wood thrushes require large territories during breeding season, which means healthy populations indicate intact forest habitat. Their presence here near Blue Rock suggests these woods provide what they need: dense canopy cover, rich soil that supports abundant invertebrate life, and minimal disturbance during the critical months when young birds fledge. The wood thrush you hear calling from the mid-canopy at dusk is both hunter and indicator, both participant and measure of this place's health.The light is beginning to slant lower through the redbud leaves now, casting longer shadows across the woodland floor where that wood thrush continues its methodical search.
