Sand Ridge, Calumet City, IL • July 2025

In recent years, I’ve visited Sand Ridge more often in the early spring, to locally see skunk cabbages and ephemerals. On this day in July, it’s rainy and overgrown with the amorphous green of a late summer urban woodland.

In the rain, the amorphous green belies the competition in front of us: just out of frame,

the hedge bindweed vine is twisting up Phragmites, taking down and smothering this towering invasive plant. Living the vine life is just about spreading out and getting as much leaf area in sun as fast as possible. Think kudzu, bindweed, invasive Fallopia.

I’ve been visiting the same fen orchids at Sand Ridge for a few years now in different seasons. Note to self – remember that late-July is likely too late to see them in flower!

The swamp mallow are just starting to flower. In another few weeks, either side of the boardwalk will be profusely fuchsia!

An assortment of other plant friends (and enemies!) on the trail:

Marian R. Byrnes Park, IL • May 2025

This place is a unique kind of urban infrastructure. Van Vlissingen Park has been owned by the Chicago Park District since 2011. When we first started visiting, it was an overgrown, impenetrable, Phragmites-filled mess, like many public lands around Chicago in the 80s through early 2000s.

And the “habitat restoration” isn’t back to some pre-colonial time; this is no remnant habitat here. It’s a spontaneous ecosystem that moved in on a bed of slag and construction waste and has been strengthened and structured by the Park District.

This is how urban restoration works.

Some of the waste continues to erupt from layers of soil; bricks and building materials form vignettes highlighting the ever present human input into these urban ecosystems.

Now that it’s Marian R. Byrnes Natural Area, the beautiful slag barrens – prairie and wetland – are showcased with a boardwalk, alongside a luxurious woodland path through cottonwoods and young oaks, and an overlook at the far north side.

Alisma inflorescences from last year, and new vegetative growth

an honor for another explorer of underappreciated ecosystems to make his mark here!
with the water level down across the site, you can see balled up Nostoc, slowly dehydrating

Powderhorn, Chicago IL • April 2025

Powderhorn encompasses a vast tract of land, owned and managed by the Forest Preserve District of Cook County, on the far southeast side of Chicago. It’s a stocked lake with fishers all year round, an award-winning remnant dune and swale habitat,

a to-be-acquired industrial lot with rail tankers, a railroad track lined with Phragmites, and disused land in a residential district made into an urban sponge that captures rainwater and drains it in to the lake. Altogether, it makes a really nice urban greenspace

that works with the land and hydrology and habitats, and enhances what they already are (minus some invasive species and plus some light mowing). Check out this terrific Storymap about the most recent restoration project!

We saw lots of evidence of beavers!

and other wildlife — like this osprey on a nest on a human-constructed osprey tower!

Thornton Quarries, IL • September 2024

we drove all the way along thornton-lansing road, ignoring our usual stop at the fairy ponds, and drooling at the restored forest preserve to the south;

then turned south, wiggling beside, and then across, thorn creek. (I was focused on driving so these are all snips from google street view:)

“and where,” I mused, “are the quarries?” So we drove further west and my god they are huge. hidden, sloppily, by recruits from the local seed pool, or so completely by earthen berms, that it’s not clear exactly where they are.

then we noticed a lookout on the east side of this southern quarry. no one else was around.

we were unable to actually access the lookout, but it’s clear it wasn’t too long ago that people were invited into this space by manicured junipers and fossils. what a view it must have been!

unfortunately there was not an easy way to bypass the fence, so we walked tamely back east, along the mowed grass and gravel, both dusty. it’s been weeks without rain. the young trees – ash, tree of heaven, buckthorn – sadly hung their leaves, in heavy yellows and reds.

It’s not a place where I’d like to fall in, but nothing is more inviting than restricted access…
