A Tree Inventory Underway in Herrontown Woods

If you are hiking in Herrontown Woods and notice a tree tagged with a number, it's part of a tree inventory underway in the preserve. 

At some point in its history, the word "arboretum" was added to the preserve's name, as reflected in the current, highly faded sign out on Snowden Lane, and the current wikipedia page. Though Herrontown Woods certainly has a lot of trees, there's no evidence of any past effort to consciously create a tree collection. 

Since being founded 10 years ago, FOHW has worked to bring back many native woody species marginalized by introduced diseases, heavy shade, or intense deer browse. Among these are the butternut, the American chestnut, serviceberry, hazelnut, azalea, and hearts a'bustin. 

Though we've dropped the "arboretum" from the name of the preserve, it seemed like it would be fun to better understand and highlight the many kinds of trees found here. 

Thanks to the initiative and organizational elan of FOHW volunteer Alastair Binnie, we have thus far tagged and catalogued 266 trees and large shrubs, comprising 65 species. 

Helping out is Princeton High School graduate Jack Durbin, who is spending some of his gap year volunteering at Herrontown Woods. Jack has been helping in many other ways as well, including building and installing plant cages, cutting invasive species, and improving the trailhead at Princeton Community Village.

We've documented trees along all the trails at this point, with Jack doing the tagging, Alastair recording, while I add locations on a map created some years back by Alison Carver. 

Along the way we've been tempted to include in the inventory a few specimens of ash tree, now nearly all lost to the hidden ravages of the emerald ash borer. Here's one's beautiful deeply furrowed bark.

One of our goals with the inventory is to create a self-guided Tour of Trees that people can take when they visit Herrontown Woods.

A Dragonfly Walk with Mark Manning

This summer, we pitched the idea of a dragonfly walk to Mark Manning, a Hopewell science teacher with broad and deep knowledge of nature, with a particular passion for amphibians and dragonflies. Mark's first choice for a location was Rogers Refuge, the wonderful wetland just down from the Institute Woods. In 2021, he and his sons had compiled an impressive list of 36 Odonata species (dragonflies and damselflies) there. But logistical difficulties shifted the walk to Herrontown Woods. 

Having not yet seen any dragonflies this year, I was wondering whether the walk would acquire the same existential feel we had some years back when a mushroom walk we hosted coincided with a prolonged drought. I cut a path down to a pond on preserved pasture land near Veblen House, but the pond was dry.

As with the mushroom walk with very few mushrooms, however, our July 1 phantom dragonfly walk proved satisfying nonetheless. Mark talked about the relatedness of milkweed and dogbane in the Botanical Art Garden, 

and told the story of how the toxin Tremetol in white snakeroot caused thousands of deaths in the Midwest when settlers drank milk from cows that had eaten the plant. 

A couple of Mark's former students who came along were not squeamish about picking up frogs to show us close up. 

And we did in fact see a couple dragonflies: an Eastern Pondhawk in the pasture, and two Common Whitetails where the red trail crosses the gas pipeline right of way. 

One added benefit of the walk was that it got us thinking about how we might better cater to the needs of dragonflies at Herrontown Woods. That dry pond in the pasture may be dry because the outlet needs repair. And might it be possible to build another little pond, of the sort we witnessed during a recent visit to Bowman's Hill Wildflower Preserve? 

Thanks to Mark for leading the walk, and for his work in inventorying Princeton's Odonata and getting us thinking about their habitat needs.

Our Pair of Black Vultures Lost Their Progeny

For as long as I can remember, a pair of black vultures has arrived at Herrontown Woods each spring to raise their young in the corncrib next to this little red barn. We'd see them perched on the chimney of the derelict Veblen Cottage, and think them a bad omen. But in 2017, one of their two chicks was slow to develop, and we watched as the parents patiently tended to it until it could join them up on the Veblen Cottage roof. The word online is that black vultures mate for life and are devoted parents. As we watched the immature vulture gain strength and ultimately join its parents on top of the chimney, our uneasiness about vultures turned to affection. They do, after all, perform considerable custodial work in nature, cleaning up messes that the rest of us steer clear of. 

If one thinks about it, our initiative at Herrontown Woods involves a great deal of scavenging, that is, finding promise in what the rest of the world has forsaken. The boarded up house and cottage, overgrown trails and a derelict pine grove filled with invasive species--these scenes of long time abandonment have been for us prize finds.

The past couple years, I've only seen one black vulture hanging out near the barn. Though I generally stay away from the corncrib, not wanting to disturb them, I have checked a couple times and found it empty. The story I told myself was that the male had lost its mate, and now returns as a bereft spouse each spring to linger and grieve. 

On June 20 this year, when friend and hiker Georgette texted me that she had found a dead black vulture lying on the ground along the red trail that runs past the Cottage, I thought we were witnessing the end of an era. 

It was a surprise, then, to come across the carcass and find not the last adult vulture but instead a bird that was clearly immature, with baby fuzz on the wings. The pair of vultures had been there after all, secretly raising their young. 

As I took a close look at the fallen bird, one of the parents looked down from the ridge of the barn. What sort of grief does a vulture feel? It's not clear how the young bird died. There was no clear sign of damage on its body. 

Having not seen the adult vulture, or vultures, since that day, I now tell myself the story that the pair have headed off for another year of scavenging, to return again next spring, to make another go of raising young. We'll see if my story proves true this time.

The Joys of Midsummer Music in the Woods

This is the third year that the Friends of Herrontown Woods has collaborated with actor Vivia Font and the Princeton Public Library to stage a mix of music and poetry on the tranquil grounds next to Veblen House. 

July 15 arrived, however, with ever-shifting predictions of rain that in turn finally prompted a shift of venue to the library's Community Room.

Despite the move indoors, the program proved a delight, and nature was not to be denied participation.

 

Vivia read some of her favorite poems on nature, including The Rose That Grew From Concrete, Who Has Seen the Wind, Morning Love Song, and Arbole, Arbole, which she read in both english and spanish. 

The energy generated on stage by the Ragtime Relics was channeled into dance (a friend told me the sophisticated dance was called a Balboa). 

And nature managed to participate through an open doorway, when a couple of our younger friends of Herrontown Woods decided it would be great fun to race across Hinds Plaza and back, just as the rain was reaching full tilt. Returning with their joy, they fed us as we were being fed by the music and poetry.

Thanks to Vivia Font, the library's Janie Hermann, and FOHW's Inge Regan for organizing a midsummer event of such beauty and spirit.

What's Bloomin' in the Barden in Early July

During our Sunday morning volunteer sessions at the Botanical Art Garden in Herrontown Woods, we've been doing lots of editing of nature's tremendous creativity. While we're weeding out low creepers like cinquefoil and vetch, limiting the prickly blackberries and wineberries, and pulling out vines like oriental bittersweet and Japanese honeysuckle, the native wildflowers have been cheering us on.

Here's the classic purple coneflower (Echinacea purpurea) blooming in the circle of labeled wildflowers around the gazebo.

Competing in the white spire category are bottlebrush buckeye,

Culver's Root,

Black Cohosh,

and Spanish Bayonet (Yucca filamentosa). Of these four spire-shaped flowers, only the black cohosh can be encountered along the trails. The others are native but not commonly seen growing in the wilds of Princeton.

There are still some clouds of Tall Meadow Rue blooming, 

and some beebalm poking through here and there.

This pokeweed was lucky to sprout in a spot large enough to accommodate its gracefully gangly growth. 

And I was surprised to find Enchanter's Nightshade looking so enchanting, on an embankment overlooking a stream next to the parking lot. 

One of my favorites, and a favorite of the pollinators, is Shrubby St. Johnswort. Walking by a six foot stand of it the other day, I was surprised by the intensity of the pollinators, and was reminded of a phrase in a poem close to my heart: "the bee-loud glade," from Yeats' The Lake Isle of Innisfree. To keep the paths clear, we're potting up this small shrub's many seedlings to sell to visitors to plant in their own yards.

Meanwhile, in the raingarden that protects Veblen House from runoff, a buttonbush is blooming near a bluebird house.

Nature Walk Led by Sarah Roberts

Thanks to Sarah Roberts, native plant advocate, for leading a June 4 nature walk at Herrontown Woods. Sarah and her husband Larry tend to a beautiful garden in their backyard in Montgomery. 

The walk was organized by FOHW board member Inge Regan (left). That's Sarah in the middle. 

Serving ably as a sort of sweeper for the walk was Inge's son, Aidan, who walked ahead of the group, pruning back any foliage overhanging the trail--a bit like those team members with the brooms in curling. 

Nature walks at Herrontown Woods tend to happen on first Sundays. Check events at HerrontownWoods.org for details. 

New at the Barden: Installations and June Blooms

We recently completed some new installations at our award-winning Botanical Art Garden (BArden for short). One involved great effort; both involved considerable doses of serendipity. 

Our new gathering platform is now complete, made largely of scavenged materials. It is a layer cake of reuse, with repurposed boards and flooring supported by long, sturdy pallets stretched across two fallen pine trees. The rustic railings are crafted from well-preserved eastern red cedars that died long ago in the nearby woods after being shaded out by taller trees. 

Thanks to FOHW board member Scott Sillars for applying his skill and determination to completing this project. Maybe we should call it "Scott's Landing."

If you're sitting in the gazebo at the Barden and suddenly hear a soft chime in the distance, it is almost certainly coming from a newly acquired grandfather's clock. I had spotted it, put out with the trash on Snowden Lane, and thought "Wow! A grandfather clock on the curb!" But it wasn't of the quality that you'd want in your house. It took our caretaker, Andrew Thornton, to see the potential new career for this discard at the Barden. The dial even says "Country Time." 

Every garden clock deserves a nice roof, and we just happened to have a spare roof lying around, scavenged from discarded play equipment earlier this year. Hopefully the roof is sufficient to keep ol' granddad chiming.

Among the flowers blooming at the Barden:

Elderberry -- we're hoping to serve an elder flower beverage at the Veblen Birthday Bash, 4-8pm on June 24 next to Veblen House.

Common milkweed. We also have purple milkweed at the Barden, which has a deeper color to the flower.

Fringed loosestrife, whose shy flowers point down.

Lots of sundrop blooms this year. The closely related evening primrose will bloom later in the season.

Up at Veblen House, in the stone circle horse run, is moth mullein, a non-native. Wooly mullein is another non native that blooms later.

Veblen Birthday Bash on Saturday, June 24, 4-8

Join us on the Veblen House grounds to celebrate summer and the birthdays of the Veblens, who donated Herrontown Woods as Princeton's first nature preserve. Dinner is potluck, so please bring a dish if you wish to partake. We'll provide drinks and appetizers, ping pong, badminton and other lawn games. We're also working on special beverages with locally harvested elder flower and spicebush, which may be available for the sampling.

Park in the driveway at 452 Herrontown Road, or walk up the orange trail from the main parking lot for Herrontown Woods, off Snowden.

Oswald Veblen was born on June 24, 1880, in Decorah, Iowa. Elizabeth was born a year or two later, on June 22 in Yorkshire, England. They found each other in Princeton, and together they had a transformative impact, on Princeton and the world beyond.

A Mothers' Day at Herrontown Woods

Mothers' Day, on May 14, coincided with our regular Sunday workday at Herrontown Woods. It was a day of beauty and serendipity as we mixed weeding with socializing with families out for a walk in the gorgeous weather.

This boy found a 4 leaf clover in the field next to Veblen House. Some people just have the knack. And while I chatted with his parents, he found lots of cool rocks, too. His parents told me he was already up for two hour long nature walks at the age of two. Looks like we have a budding naturalist here.

New volunteer, Kalyan, who has been helping pull up garlic mustard across the stream from the Barden, came across a box turtle in the area where we've been subduing a giant clone of wisteria.

Hard to capture in a photo, but it was a pleasure to gaze across this newly created vista: a valley coated with skunk cabbage and ferns, now relieved of privet and other invasive shrubs by volunteer Bill Jemas and other members of our Invasive Species of the Month Club, led by FOHW board member Inge Regan.

There were flowers large and small. The fragrant snowbell (Styrax obassia) 

was in full bloom behind the Veblen House. 

A tulip tree flower on the ground caused us to look up at all the others blooming high up.

Tiny blue flowers near the ground are called blue-eyed grass (Sisyrhinchium), 

though their flat stems show they are really related to irises, not grass.

The pagoda dogwoods we planted in the Barden are now big enough to bloom.

One of the pleasant tasks for the day was digging up volunteer native plants that have sprouted in the paths of the Barden. We can clear the paths while gaining a new plant to put elsewhere. Environmentalists love win-wins.

Still working on the installation of this little pond, but it's already attracting frogs. A vernal pool naturally formed by a fallen tree nearby was full of tadpoles and salamander larvae.

A new feature in the Barden, and also next to the Veblen Cottage, are arrow trees that tell of significant places associated with the Veblens' lives and legacy. 

So much to enjoy and be grateful for on a Mothers' Day in May.
