Chestnut sprouts and beech disease in one forest

July 11, 2026

On a July afternoon in the Groton woods, two tree catastrophes are unfolding in the same patch of shade. saplings are sprouting from old roots and stumps — survivors of a blight that eliminated four billion trees across eastern forests a century ago. Those sprouts represent resilience of a sort, a genetic memory of species that once defined the canopy.

But a few hundred yards away, trees are failing to — a nematode-driven pathogen now documented across more than 30 sites in New Hampshire and Massachusetts. Unlike chestnut's abrupt collapse, beech is failing slowly, tree by tree, leaving a forest structure intact but hollow. Two mast failures, one unresolved.

Copper discharge threatens mussels during summer low flow

July 18, 2026

The Milford wastewater treatment plant released copper at nearly double its permitted level last quarter — marking the second consecutive violation for the facility. The timing is particularly acute: summer low flows concentrate whatever enters the water, and (Unionidae) inhabit these rivers and are exquisitely sensitive to copper toxicity.These native filter-feeders rely on clean water to survive. Copper bioaccumulates in their tissues and disrupts their metabolism even at low concentrations. With the plant now running a pattern of non-compliance and river flows at their annual minimum, the margin for the mussel populations narrows considerably.

(Lycorma delicatula) has arrived as a permanent resident. Twenty-five research-grade sightings across the Boston region since early June — from Wellesley through the inner suburbs — suggest that egg masses overwintered locally for the first time. Until recently, these speckled insects appeared only as summer visitors drifting north from established populations farther south. Now they are here year-round.The presence of throughout the area has provided the foothold. This weedy woody plant, which thrives in disturbed ground across suburban Boston, is the lanternfly's preferred host. From here, the insects are beginning to move onto native fruit and timber trees — apples, maples — that formed the backbone of the New England orchard and forest economy for centuries. What begins as an incidental pest on an invasive weed threatens to become an agricultural problem.

Gray birch seeds fall as warblers arrive

May 22, 2026

The gray birch stands release their seeds now in late spring, each catkin breaking apart into thousands of papery fragments that spiral down through the warming air. If you're walking beneath these trees, you might notice the faint rustling as the tiny winged seeds settle on your shoulders or catch in the new grass. The timing is precise. Just as the Northern Parulas and other migrant warblers reach their breeding territories, the birches finish their work of the year.The Northern Parula moves through the mid-canopy with quick, deliberate motions, its blue-gray back and yellow throat bright against the fresh green leaves. This small warbler has traveled from Central America to find the right combination of moisture, insects, and nesting material. It seeks out places where old man's beard lichen drapes from the branches, weaving the gray strands into a pouch-shaped nest. The parula's buzzy trill rises and falls as the male establishes his territory, a sound that carries clearly in the still morning air. While the warbler hunts for caterpillars and emerging flies, the birch seeds continue their descent, creating a carpet that will feed other birds through the summer months.The gray birch completes its reproductive cycle quickly each spring, producing small cones that mature and release their contents before the heat of summer sets in. Each seed weighs almost nothing, designed to travel on the slightest breeze, but most fall within a few hundred feet of the parent tree. The American Goldfinches will work these seed patches through June and July, their bright yellow forms easy to spot as they cling to the spent catkins or forage on the ground. The seeds provide the high-fat nutrition that goldfinches need during their own delayed breeding season. Unlike most songbirds, goldfinches wait until midsummer to nest, timing their reproduction to coincide with the abundance of seeds from birches, thistles, and other late-flowering plants.The forest holds both arrivals and departures now. While the parulas and other warblers settle into their breeding routines, the birches shift from reproduction to growth, putting their energy into expanding leaves and strengthening roots. The dropped seeds create small disturbances in the leaf litter where they land, and some will germinate in the filtered sunlight of small clearings. Others will be carried further by wind or water, or stored in the cheek pouches of chipmunks for winter caches they may never retrieve. Listen for the parula's ascending buzz somewhere in the canopy above you. The sound rises like a question, then drops to a definitive note, repeated every few seconds as the bird works its way through the branches where the last birch seeds are still falling.
