Field report — Speak for the Trees

July 1, 2026

An ozone surge is forecast for early July—air quality rising into the moderate range, with peak intensity expected July 2–3. This annual midsummer pulse has become a quiet ecological routine across the region, a byproduct of the Triangle's growth and the chemical reactions that summer heat and traffic exhaust trigger in the lower atmosphere.

For the organisms living through it, the harm is cumulative and nonlethal until it compounds. Black cherry and milkweed—both common in the local landscape—show visible leaf damage when ozone reaches these levels during the breeding season, their photosynthetic machinery working harder to survive the oxidative stress. Dragonflies and other insects that depend on milkweed as larval host plants or as nectar sources feel the pressure indirectly, season after season. Trees that can tolerate a single ozone event may weaken over years of repeated exposure, their growth slowing, their ability to produce seeds and feed wildlife gradually declining.

Right now, particle pollution in the fine range is also forecast moderate—less dramatic than the ozone story, but part of the same pattern. This is what ambient air quality looks like in a region where ecological and human health are now inextricably linked.

Carpenter bees work the mulberry trees

June 14, 2026

The air hums with a deeper note than usual near the white mulberry trees in Durham's neighborhoods. If you step outside now, the sound carries a purposeful weight, different from the higher pitch of smaller bees. These are eastern carpenter bees, and they move through the canopy with deliberate focus.Each female carpenter bee measures nearly an inch long, her black body gleaming with a metallic sheen. She hovers at the clusters of white mulberry flowers, her wings beating fast enough to blur but slow enough to produce that distinctive low drone. The white mulberry is an invasive tree from Asia, but the carpenter bee treats it like any other nectar source. She extends her long tongue into each tiny flower, collecting nectar while pollen grains stick to the dense hairs on her legs and abdomen. When she moves to the next flower cluster, some of that pollen transfers, completing the tree's reproduction whether she intends it or not.The timing works perfectly. White mulberries bloom in late spring and early summer, just as the carpenter bees emerge from their winter dormancy and begin their own reproductive cycle. The female bee needs protein-rich pollen to provision her nest, which she excavates by boring perfectly round holes into dead wood or the eaves of buildings. She chews through the wood fiber with her powerful mandibles, creating tunnels where she will lay her eggs and stock each cell with a ball of pollen mixed with nectar. The mulberry pollen provides essential amino acids her larvae need to develop. In return, her visits between flowers ensure the tree produces the dark purple fruits now ripening on the branches.This relationship extends beyond the mulberry trees. Carpenter bees visit native black cherry and serviceberry as well, both of which also fruit in midsummer. They work the same pattern: hovering at flower clusters, probing for nectar, picking up pollen, moving to the next tree. Their size allows them to handle larger flowers that smaller bees cannot access effectively. Their long tongues reach nectar that remains out of reach for other pollinators. They are not the most efficient pollinators for any single plant species, but they are reliable generalists, working whatever blooms the season provides.The low hum continues overhead as another carpenter bee approaches the mulberry canopy. The sound carries a quality of concentration, each wingbeat measured and deliberate. If you look up now, you might catch the metallic glint of her body as she moves between the pale flower clusters, her movements unhurried but purposeful in the warm summer air.

Night herons hunt at dusk

May 30, 2026

The air grows still along the wetlands near the American Tobacco Historic District as the sun drops behind the tree line. Light shifts from gold to gray, and the sounds of the day begin to fade. This is when the Yellow-crowned Night Herons emerge from their roosts among the magnolias and green ash, stepping deliberately into the shallow water.A night heron stands motionless at the water's edge, its stocky body balanced on long yellow legs. The bird's head tilts slightly as it watches the bottom through the darkening water. It waits. Minutes pass without movement except for the slow rise and fall of its chest. Then, with sudden precision, the thick black bill strikes downward and emerges with a crayfish clamped between its mandibles. The heron tosses its head back and swallows the crustacean whole.Crayfish move more freely as darkness approaches, leaving their rocky hiding places to forage in the open water. They scuttle backward when threatened, their claws raised in defense, but the night heron's strike is faster than their retreat. The bird's eyes are positioned to judge depth accurately, and its neck muscles can drive the bill through water with enough force to penetrate a crayfish's shell. During nesting season, both parent herons hunt through the evening hours, returning to their stick nests with crops full of crayfish, small fish, and aquatic insects. The young grow quickly on this protein-rich diet, their gray down giving way to the streaked plumage of juveniles.The night heron steps forward into deeper water, each movement deliberate and controlled. Other species share this hunting ground at dusk. Common Grackles wade in the shallows, probing for insects, while Eastern Pondhawks patrol the air above the water's surface. But the night heron occupies its own niche in this timing and technique. As the last light fades, it becomes a shadow among shadows, perfectly adapted to the boundary between day and night. The water laps gently against the muddy bank, carrying the scent of wet earth and new leaves.

Yet the waters beneath tell a more complicated story: six of seven nearby streams are federally listed as impaired, carrying urban runoff and nutrient loads that have pushed them into violation of clean water standards.Aquatic insects absorb Piedmont stressors before terrestrial life does, and this timing matters.
