Turning Useless Lawn into Vital Habitat

4 Replies

As the winter chill wears off, many of us are anticipating how we can spiff up our yards. That can be a tall order when we’ve inherited a landscape of sterile lawns and imported ornamental plants that have no business growing in Montana—or, most likely, wherever else you happen to live. Fortunately, this situation presents us with a wonderful opportunity to bolster the native ecosystems we know and love. How? By replacing exotic species with native plants that are both beautiful and provide real value to birds, insects, and other native wildlife.

Our blue penstemon and other flowering plants feed a host of native insects, including a variety of bumblebees.

A Scientific American article titled “The American Obsession with Lawns,” points out that lawns began sprouting up in America in the nineteenth century. They were an attempt to emulate trendier Europeans and, more important, to display wealth and status. Fast forward to today, and a house doesn’t seem complete without its neatly-mowed spread of Kentucky bluegrass. Unfortunately, our obsession with lawns comes with a host of problems.

As you can see, we aren’t purists. Here, native mock orange (white flowers), snowberry, and fireweed thrive amid California poppies and some kind of honeysuckle I can’t recall the name of!

Especially in the West, lawns gobble up water that we can scarcely afford. Just how much depends on location and other factors, but keeping a lawn alive can devour between 15 and 75% of a family’s household water consumption. Keeping those lawns green and pristine-looking also can be expensive, especially factoring in the gas and electricity required to run lawnmowers, and the fertilizers and herbicides to keep lawns green and weed-free. Speaking of “weed-free,” despite industry claims that herbicides and other garden chemicals are safe, I am skeptical. Do you really want to be dumping things into the soil that may persist for decades and have unknown long-term health risks. I don’t—especially when my yard sits only twenty feet above the aquifer that I and the rest of my community depends on for drinking water.

Despite industry claims, I don’t think we’ll know the full impacts of a lot of chemicals for years. Unless we want to keep repeating chemical disasters, it seems prudent to avoid commercial herbicides and insecticides whenever possible. Replacing at least a bit of your lawn with native plants is a great way to do that.

All that said, my biggest beef with imported lawns and plants is that they have needlessly transformed productive habitat into sterile expanses with almost no useful function. Sure, a lawn is great for kids to play on—we keep a patch of it ourselves—but our grass obsessions have come at an extreme cost to wildlife, especially to native insects and birds. Many of you have probably heard the shocking statistics that America has lost one quarter of its breeding birds in the short space of fifty years. There are many causes for this, but habitat loss probably ranks at the top. While much of this loss may have been unavoidable, in the case of our lawns, it is not.

Even common, beloved birds have seen dramatic declines in the past fifty years, and habitat loss is often a culprit. Yards filled with native plants can be a major step in reversing this trend. (This is a newly-fledged Black-capped Chickadee sitting in one of our mock orange plants.)

Author Douglas Tallamy (Nature’s Best Hope) points out that 40 million acres of our nation’s natural habitats have been converted to turfgrass—an area about 42% the size of Montana! If we “turf owners” convert just half of our lawns to native habitat, it will restore an area larger than the Everglades, Yellowstone, Yosemite, Grand Teton, Canyonlands, Mount Rainier, North Cascades, Badlands, Olympic, Sequoia, Grand Canyon, Denali, and the Great Smoky Mountains National Parks. Talk about your game changer!

One great thing about native plants is that once you put a few in, they find where else they want to be. This patch of beebalm came up totally on its own—much to the delight of honey bees, bumblebees, and butterflies. (Golden currant in the background, angling up to the right.)

Fortunately, converting your yard to native plants is fairly easy to do. A simple online search reveals nurseries that offer native plants all over our state (also check your native plant society—see below). You don’t have to create your own “national park” all at once. Just dig up a strip of your present lawn and put in some native shrubs. Here in Montana, you’ll want to stick to deer-resistant plants such buffaloberry, juniper, or maple sumac—or better yet, protect plants with fencing until they grow large enough to thwart deer. Before planting trees, think about how big that tree is going to be in fifty or one hundred years—and plant it in an appropriate spot. If you live in a fire area, you’ll want to make sure you keep a defensible space around your house, too.

Native plants don’t just “grow” native insects. Many provide fruit and seeds for birds, as this berry-laden serviceberry branch shows.

Incorporating native plants into your yard brings immediate rewards. Our modest native plantings attract chickadees, juncos, wrens, kinglets, and other native birds, many of them feeding on the insects that the plants produce. Why not join the fun? You’ll discover a whole new aspect of gardening, and take satisfaction in helping the wildlife we hold dear.

This House Wren and its mate successfully raised a batch of youngsters in our yard last summer. At times, the pair were bringing caterpillars and other insects to their chicks every two or three minutes! To my satisfaction, I watched them grab most of these insects right off of the native plants in our yard!

Sneed’s Favorite Native Plants for the Yard That Don’t Need Deer Protection: buffaloberry, maple sumac, juniper, mountain mahogany, chocolate coneflower, yellow coneflower, Oregon grape, pussytoes.

Sneed’s Favorite Native Plants That Do Need Deer Protection (at least until they grow larger): golden currant, beebalm, burr oak, purple coneflower, mock orange, aspen, rabbitbrush, serviceberry, cottonwood (need a LARGE space).

A Word of Advice: Never, EVER plant any grasses unless you really know what you’re doing. Even native grasses can quickly get out of hand—as I have learned the hard way.

To find out sources of native plants and seeds, check the website of the Montana Native Plant Society. They have lists of resources for every part of the state! If you don’t live in Montana, you probably have your own native plant society you can look up! Here in Missoula, another great resource is Watershed Consulting, which has a wonderful native plant nursery. You can get their list via:

Website: www.mtnativeplants.com; Email:  hello@mtnativeplants.com; Andy Martinez, manager: 406.529.7746

If you can’t find a good source of native plants near you, call up the wonderful Audubon native plant database. There you can just enter your zip code and begin finding the best plants to put in near you. Even better, you can purchase the plants directly from the website.

Hawai’i: The International Jungle

During Spring Break this year the Hellgate High School Band travelled to Oahu, Hawai’i for the Pacific Basin Music Festival. Almost every day my friends and I worked with music professors, performed, and enjoyed music in many different forms. The festival provided us with experiences we’d never forget. However, we did not spend every second playing—we actually had quite a bit of free time. During this time, we hiked, surfed, snorkeled and shopped around Honolulu, giving me time to take in the island and its birdlife.

White Terns lay their eggs precariously on bare branches, without nests. In Oahu, the White Terns did not discriminate between native and nonnative trees.

Only about 6 of the birds I spotted on the trip were actually native to the island chain (Brown Booby, Hawai’ian Coot, White Tern, Pacific Golden-Plover, Oahu Amakihi and Wandering Tattler), which opened my eyes to the exotics of the tropics. The city of Honolulu itself was an international jungle, full of plants and birds from all over the globe. A few native Hawai’ian birds had taken to the civilized landscape; wintering Pacific Golden-Plovers lounged on lawns, suited in their dappled patterns, and ghostly White Terns floated between skyscrapers. The majority of the birds, though, hailed from other continents. Familiar birds included Rock Pigeons and House Sparrows (Europe), and House Finches and Northern Cardinals (North America). Lawns yielded a high diversity of species, including Common Mynas, Red-vented Bulbuls, Chestnut Muñias, Zebra and Spotted Doves, and Java Sparrows (Asia) and Cattle Egrets, Common Waxbills, African Silverbills and Yellow-fronted Canaries (Africa). Red-crested Cardinals (South America), which are brilliant gray birds topped with crimson crests, sang from palm trees.

Red-crested Cardinals swarmed the streets of Honolulu. They were almost as common as pigeons!

One morning, when hiking through densely rain-forested canyons, I encountered a plethora of different species. I did manage to hear one native, the Oahu Amakihi, but the forest echoed with mostly non-natives’ songs, like in the city. White-rumped Shamas (Asia) belted out complex, froglike songs, and Red-billed Leiothrixes, Japanese White-eyes and Red-whiskered Bulbuls (Asia) lurked high in the damp canopies. Red Junglefowl (Asia), the ancestors of domesticated chickens, as well as actual domesticated chickens, ruled the streets. By the end of the trip I had reached my goal of 30 species, even if one of them was an unidentifiable white booby (I’m guessing a Red-footed) dodging the waves off of North Shore.

The White-rumped Shama is a subtly beautiful Asian songbird that now makes its home on the forest-covered slopes of Oahu’s extinct volcanoes.

We ran into large numbers of Rose-ringed Parakeets (Asia and Africa) on several occasions, and I glimpsed a pair of Red-masked Parakeets (South America) shooting past the scrubby slopes of Diamond Head volcano in southeastern Honolulu.

Rose-ringed Parakeets (or known by pet-lovers as Indian Ringnecks) aren’t just introduced to Hawaii. Parrots escaped from a damaged aviary in Bakersfield, California a while ago, and now also can be found there with a little effort.

This raised controversial questions. Most of these species definitely did not belong here, that much was true. But now, thanks to human involvement, they had established and thrived, and many of them caused no obvious harm to the native birds. So, what should we do with them? Should we eradicate them, killing innocent birds because of a crime humanity committed? Or should we allow them to stay, letting these foreign species form their own niches in Hawai’i and other places?

In the case of many of the birds, it is too late. For better or for worse, they will be here forever, and I think that if they are not harming indigenous birds, we should let them be, and let nature decide what to do with them. Introduced predators such as cats, rats, and mongooses, however, are another matter and take a terrible toll on all of the islands’ birdlife. More resources should definitely be allocated to eliminating these destructive invasive pests.
