Silence please: you are not alone in your garden

Spring unfolds every year in color, yes, but also in sound. And sadly in noise, some of which emanates from our gardens.

When nancy, a Maryland-based naturalist and nature writer, talks about the voices of frogs or birds, she uses the word “sound.” When she refers to the voice of humanity, the rumble of lawn mowers, blowers, and chainsaws, she describes it as noise, specifically “anthropogenic noise.”

His definition: something that is “disrespectful to and glosses over all other sounds,” he said, with “often unnecessary profanity.”

These days, we’re not just driving each other crazy with the hubbub that fills most neighborhoods. We are “stifling some of the opportunities for animals to communicate through their senses,” he said, “to perceive the world through their senses.”

That means communications are masked and predator alarms and other critical vital signals are stifled.

The challenge he poses to us: “Let’s think about the fact that these are also our neighbors. And they can’t just run inside and put on noise-canceling headphones.”

But noise is by no means the only insult we hurl, as he details in his latest book, “Wildscape: Trilling Chipmunks, Beckoning Blooms, Salty Butterflies, and Other Sensory Wonders of Nature.” In it, Ms. Lawson synthesizes scientific research and her own intimate experiences in the great outdoors to impress us how fragile and precious the mechanisms of nature are.

It’s true that gardeners are now more aware than a few years ago of the importance of habitat-style gardening with native plants and the benefits to insects and other wildlife. But many conventional landscaping practices, used even by those trying to tend to the garden, have harsh, if unintended, consequences for a diversity of animal inhabitants.

A garden can be mulched just as native ground-nesting bees are provisioning their nests in spring, for example, blocking their access and effectively undoing all their hard work.

A mowed landscape is inhospitable to many creatures, including fireflies, which may rest during the day in tall grasses. And too-scrupulous cleaning removes mosses, dead wood and leaf litter habitat, places where female fireflies lay their eggs and favorite haunts of slugs and snails, a food source for firefly larvae.

“These are exactly the things that chipmunks and birds need,” Lawson said. “And we need too.”

She asks us to see (and hear, touch, taste, and smell) the world through her senses, not just our own. By organizing the book into chapters that highlight these gates of perception (Scentscape, Soundscape, Tastescape, Touchscape, and Sightscape), she suggests adjustments we can make to reduce disruption.

The multicultural world outdoors

The soundscape has special meaning for Ms. Lawson, who was born partially deaf. That has made her sensitized to the impediments other animals can experience when trying to tune in and navigate the static.

Can we dial it back, and perhaps dim the nighttime glare of artificial light, another ubiquitous man-made environmental pollutant? (A more bug-friendly quick fix: Install motion-sensing sensors on outdoor fixtures and use yellow LED bulbs, whose wavelengths attract fewer species.)

In other words: Easy does it.

“If you treat the local environment like the homeland it was meant to be,” he writes in “Wildscape,” “you will be exposed to more cultures, ideas, and ways of life than if you visited people from every country in the world.” .”

Sometimes, he said, it’s not about doing something, but the opposite: stop mowing so often; stop blowing leaves. “Stop these sensory disturbances,” she said.

Even with actions that we know can cause harm, like using pesticides, it’s not just direct harm that she alerts us to.

“It turns out that releasing scents into the world that cause odor pollution can alter the fragrances of flowers and the ability of bees to find the flower resources they need,” he said of an often overlooked Scentscape breach.

Noise also has unexpected effects, such as reducing the nesting success of bluebirds and tree swallows, and decreasing the foraging ability of owls and bats.

Or this: As the cars went by, Mrs. Lawson noticed a monarch caterpillar shuddering up from the milkweed it was feeding on near her driveway. One article she found cited the same reaction, and how traffic-stressed animals even bit researchers, something they had never documented before.

Silence please. We are not alone.

The ‘Volunteer Treasures’

Ms. Lawson’s previous book, “The Humane Gardener: Nurturing a Backyard Habitat for Wildlife,” was published in 2017. When she and her husband purchased their home in Sykesville, Md., in 2000, the property was anything but a habitat. As she describes it, the 2.23 acres included “nearly two acres of mowed grass and a sickly little rose bush.”

That first summer, she recalled, a giant pokeweed (Phytolacca americana) came out of nowhere, “and I thought, ‘This is so pretty.'” fruit many birds prefer: off with its head (and prodigious root system), they advised.

Instead, he went his own way, as he did with mowing, choosing not to, eventually producing a field of rushes (Andropogon virginicus) and purple grass (Tridens flavus). The only remaining nod to the lawn tradition is a mowed strip along the street for dog walkers and other pedestrians; his community does not have sidewalks.

The couple also dug a small pond that is filled with amphibian voices.

What has manifested itself on his old lawn is “a mini-forest,” Lawson said, “including so many species that just popped up on their own,” such as sassafras (Sassafras albidum), sumac (Rhus) and cherry. black (Prunus serotina).

A hidden courtyard within invites human visitors to sit for a while and watch, listen, inhale. In spring, a yellow-flowering Carolina jasmine vine (Gelsemium sempervirens) cascades from an adjacent terrace railing, filling the space with fragrance.

“For July, it looks like a little rainforest to me,” he said of the scenery. “It’s so shaded and much cooler even on hot days because of all that canopy.”

With the “volunteer treasures” and many plantations, the place has taken shape. Ms. Lawson recalls a recent visit from her long-time contractor, that she used to have difficulty moving through space, not knowing where to walk. Not anymore. And the paths carved between the adult plants help.

“It’s hard when you’re trying to do things more naturally and you’re making that transition,” he said, “because there’s an awkward phase for quite a while, where people don’t really get it.”

Even not-so-wild yards run the risk of complaints from lawn-obsessed neighbors. In nearby Columbia, Maryland, Mrs. Lawson’s sister, Janet Crouch, learned that the hard way, after a multi-year legal battle with your homeowners association about your pollinator garden. She won, inspiring a state law that prevents homeowners associations in Maryland from requiring residents to have lawns.

It was a victory for wildlife, who know a good thing when they see it.

“Landscapers often stress the importance of creating a sense of place so that humans feel at home,” Ms. Lawson writes. “But our wild friends know exactly where they are.”

Animals need access to all the raw materials of life that are obliterated by obsessive lawn-mowing ordinances and compulsive cleaning. Let a mossy outcrop have its way, and you might notice bald patches appearing in the spring, a sign that eastern phoebes, Carolina wrens, orioles, chickadees, and other birds are incorporating bits. in their nests.

Of course, not all volunteer plants bring pleasure. There is stiltgrass (Microstegium vimineum) to deal with. Ms. Lawson experiments with native perennials that she hopes will outperform her, including blue mist flower (Conoclinium coelestinum) and false nettles (Boehmeria cylindrica), a host plant for three species of butterflies. Northern sea oats (Chasmanthium latifolium) is another stalwart.

“I really loved seeing what I can do to displace invaders,” he said.

Late boneset (Eupatorium serotinum) is a spontaneous ally that “has helped me shift the balance to native,” he said, and not just with its late summer to fall flowers. Her leaves contain pyrrolizidine alkaloids, chemicals she has observed monarch butterflies extract from damaged or dying foliage to strengthen their defenses.

Listen: A whisper in the leaves

When we slow down and cultivate stillness, there is a chance to see those things or learn to identify the songs of birds. Perhaps we become so connected that we can finally discern the subtle difference in sound between a snake moving through the leaf litter and an Eastern Whistle or another sparrow kicking at it, or a squirrel diving headfirst.

“However, to get to the point of crunching in the ground,” he writes, “a leaf must be allowed to fall, brown, and wither in due time, without being raked, crushed, or dragged: the landscaping version of invasive cosmetic surgery.”

Sometimes, though, it feels like there’s too much to do to sit still, especially with worrisome woody invaders like Eastern bittersweet (Celastrus orbiculatus) or Bradford pears (Pyrus calleryana) swooping in from the property’s edges.

His mindset: progress, not perfection.

“I try to focus on having changed the balance a lot,” he said. “There really wasn’t anything here before that was useful to us or to wildlife. Now there is.”
