Rugosa rose peaks, crowding native dune neighbors

is at peak bloom along the coast this week — more than fifty sightings scattered from Old Orchard Beach through Casco Bay, with hips already swelling beneath open flowers. The plant is uncommonly vigorous this year.

What makes the abundance notable is what it's displacing. This Asian import was planted decades ago as dune stabilizer and has become so successful that it now crowds out native beach plum along the very dune edges where Wabanaki people traditionally gathered wild plums for food and medicine. The same ecological niche that once supported culturally significant harvesting has been largely converted to a monoculture of an ornamental exotic. The rugosa rose is doing exactly what it was brought here to do — stabilize and colonize — but at the cost of the native diversity that was already there.

Least terns nest on open ground

June 26, 2026

Along the sandy margins near South Portland, the least terns are working. You can hear them before you see them — a sharp, insistent kip-kip-kip carrying over the water, pitched higher than anything else calling from the shore. They are Maine's smallest tern, barely larger than a starling, with a yellow bill tipped in black and a white forehead patch that catches the early summer light. At this time of year, they are doing something that looks, from a distance, almost unreasonably exposed: nesting directly on bare sand and gravel, in the open, with no structure around them at all.The nest is a shallow scrape, sometimes lined with a few bits of shell or debris, sometimes nothing. The eggs sit in it and look like the ground itself, pale and speckled in shades of tan and gray. A colony may have a dozen or more of these scrapes within a short stretch of beach, each pair defending a small radius around their eggs with considerable noise and direct aerial aggression toward anything that enters. The terns fish constantly during this period, plunging into the shallows for sand lance and small silversides, then returning to trade off incubation duties. The longest days of the year give them more hours to do this, and they use them. A pair may make dozens of foraging trips in a day, each one a brief steep dive and a quick return to the colony.The colony's main vulnerability is its openness. The same bare substrate that makes the eggs hard to see from above makes the birds easy to flush from the ground. A person walking too close will lift the adults off the nest, leaving the eggs exposed to sun and, more critically, to the attention of herring gulls, which are present along this coastline in numbers and will take eggs and chicks when the opportunity is there. Crows present the same problem. The terns respond to these threats collectively — the whole colony rises and mobs the intruder — but sustained disturbance breaks that defense down. Repeated flushes during incubation can cause nest abandonment, and early summer here brings both foot traffic and the birds that follow it.Peregrine falcons hunt this coastline. A peregrine is capable of taking a tern in flight, and when one appears near a colony the response is immediate: the terns go up in a tight, fast-moving group, calling hard, and the structure of the colony dissolves temporarily into a single defensive mass. The peregrine is not focused on the colony the way a gull is — it is a fast pursuit predator, and a healthy, alert colony of small birds is not easy prey — but the disruption is real and the energetic cost of repeated alarm responses adds up across a nesting season. The terns have to balance time away from eggs against the risk of leaving them unguarded, and a persistent predator presence shifts that balance.Least terns are a threatened species in Maine, and their numbers here reflect the broader pressure on sandy beach nesting habitat along the New England coast. The beach plum along the upper margins of the shore is leafed out now, and the gray alder has filled in behind it. That vegetation line marks the edge of usable tern habitat — the birds need the open ground in front of it, and as that ground shrinks or fills with foot traffic, colonies compress or fail. What sustains the ones that do persist is the fidelity of the birds to specific sites; least terns return to the same colony locations year after year, which makes successful sites worth protecting and failed ones genuinely hard to replace.If you are near the water right now, listen for that kip-kip-kip above the low wash of the shore. The terns are small enough that you might look past them, but once you pick up the call, you will start to see the wingbeats — quick and stiff, with that distinctive hovering pause just before the dive.

Severe drought locks in over Cumberland County, and the small streams show it first

September 9, 2026

Severe drought arrived in Cumberland County in the middle of August and has not let go. On the August 4 drought map, none of the county was in severe drought. One week later, just under a third of it was, and that share has held flat at 31.59 percent for four straight weekly updates through September 7. Moderate drought or worse now covers 68.91 percent of the county, up again this week, and the whole county is at least abnormally dry. No part of it has reached extreme drought.The rain is not coming to fix it. The Portland Jetport station, four kilometers from this stretch of coast, has recorded a tenth of an inch so far in September against a 1991-2020 normal of 0.62 inches for the same days. Overnight lows there are running a couple of degrees above normal. Last summer the county came through its third-driest June-to-August on record, so this is dry ground going dry again.The place that shows it first is the small water. The Stroudwater, the Nonesuch, the Spurwink and the little Presumpscot tributaries that feed Scarborough Marsh are low-gradient, shallow streams with thin groundwater reserves. When base flow drops, they stop running and start pooling. The riffles that normally stir air into the water go dry or shrink to a trickle. The pools left behind warm faster in the afternoon sun, and warm water holds less oxygen. , a coldwater fish recorded in South Portland this spring, run into trouble near 21 degrees Celsius and avoid water below about 4 milligrams per liter of oxygen, a number a stagnant September pool can approach.Early September adds a second load on top of the first. Leaves are beginning to drop into the channels. In a stream that is flowing, that litter gets torn apart and carried downstream by caddisflies, stoneflies and mayfly larvae, the shredders that do most of the work in a forested headwater. In a stream that has stopped moving, breakdown falls mostly to bacteria and fungi. The leaves rot in place and pull oxygen out of the same pools the heat is already squeezing. The bedrock underneath most of this lowland is old metavolcanic and metasedimentary rock with almost no limestone, so the streams have little chemical capacity to buffer anything that concentrates as the water shrinks.

Tides running eight inches high push salt marsh into stress

July 20, 2026

Since mid-July, tides here have been running roughly eight inches — about 0.2 meters — above predicted levels, pushing the salt marsh edges into deeper flooding than the seasonal calendar would suggest. At this time of year, Spartina grasses are in peak growing season, allocating energy to root growth and seed set rather than managing inundation stress. A persistent high-tide anomaly hits them when they are most vulnerable to it.The Stroudwater River drains into the Fore River estuary at the inland edge of this tidal zone and sits on Maine's official list of impaired waters — a designation tied to ongoing nutrient and pathogen loading with no remediation timeline in place. When above-average tides push farther inland into an already nutrient-loaded watershed, the two pressures interact in ways harder to predict than either one alone. Tidal backflow can carry estuarine water upstream into freshwater reaches already burdened by runoff, slowing the flushing that might otherwise dilute pollutants.A small anomaly in the tide gauge, but small anomalies in a stressed system have a way of compounding. The margin between ecological recovery and decline grows narrower with each overlapping stressor.
