King County Public Health is looking for two people who may have come into contact with a rabid bat found outside a residence near the Washington Park Arboretum last week.

Officials say the encounter apparently involved people who found the injured animal and provided it water, according to a note left on the door of a Boyer Ave E home:

The bat was first identified on September 23, 2025. A King County resident found a note on their door indicating that two unknown people had given the bat water and alerting the resident to the sick bat. The bat was euthanized by an animal control agency on September 24. Public Health tested the bat for rabies and received a positive test on September 25.

Do you ever go outside to get something from your vegetable garden and stand up a half an hour later in a haze of naturalistic wonder? My partner calls it distracto-boy, and suggests I have ADD — which may be a good moniker and a not impossible diagnosis. Mostly I just think I have (a largely) undivided attention for nature.

My most recent spiral was initiated by several large bumps on the stems of the Thimbleberries, Rubus parviflorus, I planted in our yard a few years ago.

Despite trying to train myself to not lose my mind whenever I see a blemish on anything I’m growing (because mostly this is just a good sign that a plant is being used by other species around it), I couldn’t help but feel an initial bit of horror. I knew these bumps were galls, but I didn’t know if this was a death knell for the Thimbleberries I’d been lovingly watching grow over the past three years. Continue reading →

Pikes/Pines | The liquefaction zones of Capitol Hill

Separating the interesting side of geologic hazards from the true, helpless terror they can represent is a difficult task.

This is why, when you read headlines about our region’s volcanoes and earthquakes, they are rarely serene. And rightly so. Swarms of earthquakes at Mt. Rainier and tsunami warnings from Russian tremors are fear inducing, regardless of hyperlocal impact.

However, having our heads in the sand — or the glacial till — isn’t going to help.

Capitol Hill is mostly a pile of sand and rocks deposited during the last glacial maximum around 16,000 years ago. This isn’t particularly unique across the Puget Sound landscape because the entire basin was covered by glaciers, and the deposits left by their expansions and recessions is part of our environmental heritage.

Pikes/Pines | Capitol Hill’s house sparrows live in apartments

I was in a rush to get out of town a few weeks ago and needed a quick meal. A quick detour took me up to Broadway and there I was, waiting in line with a dozen other mostly sober people at Dick’s on a Thursday evening. When I stand in lines these days, I try really hard to not reflexively reach for my phone. Sometimes this means I have awkward conversations or eavesdrop on awkward conversations. Mostly I daydream and consider my surroundings. In this case, I looked down to see several small brown birds, one with a handsome black bib, picking at bits of food and other detritus around our cueing feet.

They were House Sparrows, Passer domesticus, birds so common that like gulls and pigeons, they often get overlooked. As a kid I’d reflexively leave them off my bird lists along with European Starlings and today still occasionally mark them with an “X” rather than counting them on eBird, which purists consider a cardinal sin. They are one of the most widespread wild birds in the world, inhabiting every continent, native or introduced. Continue reading →

Stumps appear along Capitol Hill’s 15th Ave as Seattle needs help to quickly grow its tree canopy to 30%

As Seattle hopes to help cool its streets and sidewalks against global warming by achieving 30% tree-canopy coverage across every area of the city in the next twelve years, the new stumps along Capitol Hill’s 15th Ave are an example of the challenge — and the opportunity — in the numbers.

The old Norway Maples just removed from the sidewalk along the Capitol Hill Kaiser Permanente campus were dead — and had been for years. Planted in 1977, the maples were maintained by the Seattle Department of Transportation. Coming up on 50 years later, most of the 15th Ave trees were completely dead with branches and bark falling off. A few hangers-on were in serious decline.

SDOT says it hired a contractor to remove the old maples “due to safety concerns, particularly because they were adjacent to Metro bus lines.”

SDOT says there is no evidence “porous paving contributed to the trees’ decline” as the city’s tree wells have been filled in recent years to prevent injuries to pedestrians and people using tree-lined sidewalks.

Despite the city’s ambitious goals of quickly establishing a 30% tree canopy cover, there is no plan for re-planting. But there will be a first step. Continue reading →

The fallen willow at Streissguth Gardens

Streissguth Gardens, on the sloping hillside between 10th Ave and Broadway, lost an iconic willow tree after a wet snowfall this winter. The willow, seemingly weighed down by the snow, fell westward and perpendicular across two of the park’s paths of thin, winding trails.

“It’s kind of bizarre. I never really thought about losing it until it came down,” said Ben Streissguth, who describes himself, unofficially, as the director of the gardens. Streissguth’s parents’ personal gardens were the beginning stages of what constitutes the one-acre space today, and though it’s unknown how old the tree was, he can remember it as far back as his teenage years. Based on Streissguth’s memory, photos and size of the tree, it is estimated that it was around 80 years old.

Streissguth, his wife and a few others, including some community members, have been working to do as much cleanup of the willow and surrounding area as possible. He estimates they’ve spent about 120 hours cleaning up and restoring the space as best they can. Further work will have to be done by Seattle Parks and Recreation.

Just three weeks after the willow fell, a maple toward the southwest side of the park toppled, too. Streissguth has taken what he can of the trees to work on the gardens. So far, there’s a new bench beneath the top of where the willow fell, made out of maple, while the pathway above where the willow stood is being reconstructed using slices of the felled maple. Instead of walking behind it, you can now look down at the willow’s massive root structure. Other projects include creating a wattle fence to create a stronger border between one of the trails and the vegetation running up to it, and edging portions of other trails with willow branches.

Though what will happen to the tree and the space left behind has yet to be decided, the Capitol Hill community around the garden has found ways to mourn the tree, often sharing different connections residents each had with it. Continue reading →

Pikes/Pines Classic | These Capitol Hill bird moms put all their eggs in one basket

At this time of year, birds often fly around carrying bits of grass, twigs, cobwebs—and sometimes, here on Capitol Hill, trash—for building nests.

Many birds lay several clutches of eggs every season in an attempt to raise as many chicks as possible.

But one of the Hill’s smallest songbirds, the ruby-crowned kinglet, has a different strategy.

The ruby-crowned kinglet gets its name from a tiny red crest on the male’s head, but this crest only pops up when he is agitated or trying to attract a female. If you see a kinglet, you may not see any red at all. You may only see a tiny gray bird with some yellowish coloration on the underside. Continue reading →

When will Capitol Hill-grown magic mushrooms be legal in Seattle?

A Capitol Hill expert has taught hundreds of people, from grandmothers to neuroscientists how to cultivate magic mushrooms guiding many into the world of psychedelics.

With years of teaching experience, they cover the responsible use of entheogens, contemporary psychedelic theory, and their therapeutic applications.

“Psychedelics are meaning-making chemicals,” the expert tells CHS. “Magic mushrooms are therapeutic, not medicinal.”

Their work is facilitated by a 2021 Seattle City Council decree decriminalizing the noncommercial cultivation of psilocybin mushrooms and several other entheogens. This decision has allowed Seattle residents to engage in home-mycology and explore the spiritual, religious, and therapeutic experiences offered by psychedelics.

But Seattle is not yet safe for psychonauts. And the shadows of the Trump administration have darkened the situation to the point where recent progress here is being slowed and rolled back.

While personal psilocybin cultivation is decriminalized, its use remains illegal. In February, a man on First Hill was busted for what police said was a “drug lab” with thousands of dollars worth of magic mushrooms set up inside a First Hill apartment unit.

Organizations like REACH (Responsible Entheogen Access & Community Healing Coalition) Washington are advocating for state-level entheogen decriminalization.

Oregon is already a step ahead. Continue reading →

Pikes/Pines | No, you can’t (entirely) blame your Capitol Hill pollen allergies on botanical sexism

I spend a lot of time outside. I tend the garden, I walk the dog, I nerd out on nature, and I even manage to sit still and relax occasionally.

These are all activities I am grateful to be able to enjoy because I know that not everyone has the same opportunities, nor can they enjoy certain seasons with the same zest.

Unlike a few of my close friends, I don’t have seasonal allergies, and have never had to look at pollen counts or use medications to simply struggle through each day. (Though woe is me, I am fairly certain I am allergic to hops.) According to the CDC, around a quarter of the adults in the US have the seasonal allergy rhinitis or hay fever, which is caused by the body’s reaction to plant pollen – so it’s not unreasonable that those of you reading don’t share my joy right now.

Most plants produce pollen and all pollen is produced for one purpose – to transfer male gametes from one reproductive structure to another, receptive one. You might read this as “I’m allergic to plant sperm,” but that’s not quite accurate. Pollen are gametophytes that generate sperm once they come into contact with an embryo sac – be that on the pistil of a flowering plant or the female cone of a gymnosperm (e.g. conifers). Just like the plants that produce them, pollen is extremely varied, the better to be conveyed by a variety of animals, as well as wind, water, or a mixture of all of the above. (If you really want to get into the weeds, both pollen and the embryo sac can be considered separate organisms from their parents but let’s not complicate things.)

A microscopic view of the pollen grains from a diversity of plants reveals a hallucinatory range of shapes, colors, and textures that help transport them between plants and protect them from getting gobbled up or destroyed by the environment. (Pollen can last for days, where raw sperm would not last hours in most conditions.) Animal pollinated plants tend to have larger, stickier, and more protein rich pollen to cling to pollinators and offer them a reward, while wind pollinated plants tend to have lighter, loftable pollen, (some even have air sacs) to balloon them as far as possible.

A couple weeks ago, Justin (our illustrious leader here at CHS), sent me an unreal looking image of a Georgia skyline filled with pollen. Accompanying this (real) image (from six years ago) were comments blaming the highest pollen count in state history on cities planting only male trees. I am often late to the party on social media happenings (Justin once asked me a question on Twitter and I finally responded a year later and didn’t even realize how tardy I was), but apparently a few years ago the idea of botanical sexism hit TikTok by storm after a single video rested the weight of all pollen allergies on the shoulders of city planners, horticulturalists, and arborists “only planting male trees.” The idea is that these male trees spew forth their pollen everywhere, and with nowhere to go, they just go forth to clog up our bodies with histamines.

Botanical sexism is a term coined by a researcher and horticulturalist named Tom Ogren, who theorized that because of a supposed preferential planting of male plants in landscaping, we are having more societal issues with pollen allergies. At surface value, this sounds pretty reasonable, and it’s true that in some cases, tree varieties bred to not produce fruit or seeds (remember the cherries of last month’s Pikes/Pines) or only clones of male trees get planted in urban spaces. Gingko trees are a good example of this, because female gingkos are almost never planted as street trees or in ornamental gardens because their prodigious fruit production is frankly horrendous, generating rotting piles of inedible fruit that can become health hazards.

Pikes/Pines | Genus Prunus — It is time to enjoy Seattle’s wealth of cherry trees

March is about one thing for me: anticipating spring. Every day I listen to more and more avian voices, thrilled by the steady increase in volume, stretching my ears to hear the first swallows and warblers. But mostly, I spend the days leading into spring anticipating the breaking of buds to reveal the season’s leaves and flowers.

For many, there is no better embodiment of this anticipation than the members of the genus Prunus, known as cherries.

Unless you live under a rock, you know that cherries are famous for their blossoms. Across the world people flock to bask in their annual profusions of all flavors between white, pink, and purple. The University of Washington Quad is locally famous for their Yoshino cherries (Prunus × yedoensis), which bear brilliant blooms before their leaves even hint at emerging. Of any country in the world, Japan takes cherry worship to unmatched heights with the number of cultivars they claim (several hundred depending on your definition), the tradition of Hanami (gathering to picnic and enjoy the blooms each year), and the use of the sakura (cherry blossom) as an important cultural symbol.
