A small herd of deer bounded away over the manicured grounds of the Logan Cemetery, tumbled through its faux wrought-iron gateway, and hurdled across empty campus streets. I watched the deer disappear into alleyways between ocher-bricked University buildings, contemplating their explosion of wild life as my city woke to a quiet dawn.The Urban Ecotone

I’ve spent the majority of my life in cities. They have a human element to them I have not yet been able to forgo, but one I sometimes find myself running away from, toward the wooded hinterlands to hide. This experience, though, with the deer in the cemetery, startled back into my memory a truth inherent to our humanity. Our domestic metropolises are just another type of ecosystem for wild beings to populate. After all, we are wild beings ourselves.

An ecotone exists where differing ecological systems meet; and along their shared border, a great wealth of biodiversity abounds- the edge effect ecologists call it. I bore witness to a variation of this phenomenon along the Northern Wasatch urban ecotone on a chilly October morning as a half-dozen deer escaped my advance.

The urban ecotone wears a wardrobe of many styles, the most obvious being the type I’ve described wherein a conspicuously wild ecosystem-my home range of Bear River Mountains in this case- meets a decidedly civilized humanscape- the small city of Logan, UT. We call Logan the “city on the edge” for good reason. It’s the last great bastion of the Wasatch Front’s human imprint before wilderness takes over. From here, our Bear Rivers bear northward into an unobstructed wall of mountains all the way to the Greater Yellowstone Ecosystem. These mountains are, in fact, one of the last intact ecological corridors connecting the northern and southern Rocky Mountains, and Logan sits on the edge of it all, reaping all the wild benefits thereon.

The subtler iterations of this sort of ecological spectacle may be smaller but are no less exciting. Ripping out a conquering crowd of last season’s mint crop in my garden this spring produced a surprised garter snake from an abyss below pungent leaves. The thin serpent slithered quickly away only to find himself upon a barren concrete expanse of patio. It paused for a moment to assess the situation, looked back at me and its former dwelling, then skipped on its belly across a freshly mown lawn and into the bushes adjacent to the creek that runs beside my home. More weeding produced several wolf spiders, a praying mantis, and a plethora of earthworms. I look forward to next year’s garden cleanup now.

Then there are the green spaces: parks and natural areas that make a city worth living in beyond what we humans may more or less bring to it. Indeed, the scientific evidence is clear; those cities, towns, and villages whose urban ecotones are active and robust produce not only a slew of diverse wild species but a slew of wildly content people as well. It seems happy people go hand in hand with happy critters and their accompaniments.

A 17-year study conducted by the University of Exeter Medical School in the UK concluded that, quote, “Findings show that urban green space can deliver significant benefits for mental wellbeing.” In an interview with the UK’s renowned Guardian Newspaper, another researcher is quoted: “We’ve only really had mass urbanisation for the last 200 years, say, out of our hunter-gather experience of 100,000 years.” End quote. Perhaps we have not grown as far from the natural world as we sometimes fear. Even in our cities, these brightly lit harbingers of our species’ growth and accomplishment, we are reduced to our elemental selves by a flash of fur through dawn’s fog. In those moments, we are just animals again.

Along the bottom of the Weber River lives a genetically-distinct fish called the bluehead sucker.

Its head is colored in dusty shades of blue, brown and gold. From the gills to the tail the fish has a pattern of gold, diamond-shaped scales with dark brown borders, which grow larger and more distinct closer to the tail.

Its large rounded nose overhangs the papillae-covered lips and mouth, which are set low to allow the fish to eat algae off surfaces.
Another distinguishing feature is its large size the adult bluehead suckers can reach a length of 16-18 inches.
One of the main benefits of the bluehead sucker in the Weber River, is its place in the food web, primarily eating algae. The cartilage scraping edges of its jaws make it easy to feed off rocks and other objects where algae may build up.

The suckers obtain nutrients from the algae, and grow to be good bait and forage fish.

Dr. Phaedra Budy, Unit Leader for the U.S Geological Survey Cooperative Fish & Wildlife Research Unit at USU said, “When both bluehead suckers and trout exist together, the suckers help take the predator pressure off of the game fish, and its feeding habits offer little competition with trout.”
This native species has intrinsic value to the river because of its ability to indicate the health of the riverine ecosystem. But changes in the river have created challenges for the sucker by limiting its habitat.

The river no longer has the freedom to meander across the landscape since it is confined by rail tracks, highways, and urban development for much of its reach. There are also two 150-foot dams and reservoirs in its path. These changes have altered both the physical and thermal characteristics and decreased the spawning habitat of the sucker.

Bryan Maloney, a former graduate student in Dr. Budy’s lab, recently completed his Master’s on the bluehead sucker. His research included determining what spawning habitat the bluehead suckers use.

To do this, Maloney compared the spawning bluehead suckers in Weber River to the ones in the pristine Ferron Creek. This comparison was essential since he needed to see what the spawning suckers chose in the unaltered streams.

Budy explains, if we only studied Weber it would be similar to observing a student who rented a really bad apartment for a semester because he was broke – then saying, “Oh, this must be what he likes to live in,” and not recognizing he would have chosen something much better if he had the resources.

By comparing the two rivers, Maloney discovered the spawning suckers use wide channels with plenty of pools, gravel, and cobble. Once the eggs hatch, the juvenile suckers use nearshore locations where the water is slow and deep and the young suckers find it easier to hide, eat, and grow.

According to Maloney, “These diverse habitat components are critical for spawning adult and growing juvenile bluehead suckers. Restoring them to the Weber River, will assist in recovering this imperiled population.”

Although Weber River is limited in these habitat characteristics, the future of the riverine ecosystem is optimistic due to the formation of the Weber River Partnership.

The agencies in the partnership include Utah Division of Wildlife Resources, Trout Unlimited, Weber Basin Water Conservancy District, both the Weber River and Provo River Water Users Associations, City of Ogden, PacifiCorp, Bureau of Reclamation, and the Davis and Weber Counties Canal Company.

Plans are underway for the fish habitat restoration in the Weber River, which will be a big help to the future of bluehead suckers, and whatever steps are taken to benefit habitat for suckers will also benefit the native trout.

As I look out my front window, 7 mule deer are cavorting, feeding, with some lying down for a mid-day siesta. With the final week of the regular season deer hunt winding down, some have taken sanctuary from the nimrods to join the urban herd.

For our 30 years in Smithfield canyon, deer have been regulars, disappearing for the most part from mid-May to mid-June to give birth, as do the bucks, perhaps somewhat embarrassed with strange bumps forming on their crowns.
Spotted fawns begin adorning our lawn in mid-July. With enough speed to outrun all but the fastest predator’s, mom drops her guard a bit. Bucks begin parading their new, fully formed head gear.

As fall and winter approach, the neighborhood herd grows, with a few dozen hanging out when winter finally sets in. Their snow trails through the yard become conspicuous, further defined with sprinkles of fecal material. Out back the steep hillside across Summit Creek becomes a winter playground as small groups run repeatedly up and down and around. Apparently, their abundant stores of energy allow them to break winter’s lethargy. This is generally not the case for deer in the wilds where every calorie is conserved for winter hardships as snow deepens and temperatures plunge.

We’ve witnessed a few humorous behaviors during our 3 decades of observation. Deer are very curious which occasionally works against their best interests. We had an especially aggressive rooster who became our “feathered” watchdog. A small deer herd passing through the front yard noticed the stocky cock guarding the front door and decided on closer inspection. The lead deer approached stretching his neck and tender nose to get a closer whiff. Old roaster rooster gave her a welcoming sharp jab to the nose which sent the herd bounding off.
On another occasion, our tomcat found itself taking refuge under the trampoline as 4 deer approached from a patch of forest. The cat’s movement piqued the deer’s curiosity. They surrounded the trampoline, bent down on front knees with noses poked underneath for a close-up. Poor tom was terrified- to be munched by a deer- what a horrible end!

Of course, we realize that not everyone is enamored with deer in their space. Deer can be a nuisance causing damage to landscapes and gardens. With proper fencing and plant selection, this can be managed. A greater concern is safety, vehicle-deer collisions. Here again, with proper signage, this can be minimized. I’ve experienced close encounters on my bike, so always go slow when deer appear near or on the roadway.
An excellent resource for landscaping is found at wildlife.utah.gov/habitat/deer-browse.php Blending a variety of native and ornamental plants into a home landscape can create a highly attractive environment for family, friends, mule deer and other wildlife species. Enhancing the home environment and replacing some of the lost wildlife habitat can be enjoyable and beneficial.

Autumn Migrations

Here comes Autumn, especially noticed in the northern parts of Utah: the colors, the cool air, the absence of many insects, the falling leaves, and the occasional dusting of snow in the mountains.

In these weather-changing conditions, wildlife species have four options: adapt to colder weather, migrate to better conditions, hibernate…or die. Today, we’ll consider migration.

As recorded by the National Geographic Society, Entomology Professor Emeritus, Hugh Dingle, mentions five basic characteristics of migration:

Prolonged movements that carry animals outside familiar habitats.

  1. They tend to be linear, not zig-zag patterns.
  2. They involve special behaviors of preparation and arrival (such as overfeeding).
  3. They demand special allocations of energy.
  4. They maintain attention to the greater mission. Meaning they are undistracted by temptations, and undeterred by challenges, that would turn other animals aside.
  5. They feel they can eat, rest, or mate later.

The entire migration movement involves body shape, physical processes, and genetics of each species.

For ten years, scientists have been documenting one of the largest aerial mass migrations on earth. According to Science Magazine, three and one half trillion insects were recorded on radar traveling from southern England to Africa and back. They represented 3,200 tons of biomass (living tissues), which was more than seven times that of the thirty million songbirds that make that same annual flight.

Movements don’t have to be monumental to be considered migratory. For instance, some consider the daily changes in depth of ocean zooplankton to be a form of migration. They spend the day near the surface benefiting from the food provided by sunlight, then sink to darker depths at night to hide.

Some rattlesnakes in Western Canada are also considered migratory as they have been tracked to relocate anywhere from 5 to 33 miles each year. This movement is spurred by cold temperatures which reduce food, and a scarcity of good den sites below the earth’s surface, which must be warm enough and at times capable of holding up to 1,000 snakes. In contrast, Arizona rattlers travel far less because they don’t require that need.

Pronghorns, which are not really antelopes, travel far and fast, around 60 miles per hour. One group travels hundreds of miles from north-central Montana up into Alberta for breeding in the Spring. Another group of nearly 20,000 goes from Grand Teton National park south to the sagebrush plains near Pinedale, Wyoming for the winter. The routes of both groups do not vary, which can be hazardous if they are blocked by snows.

Biodiversity of ecosystems and processes, which enable each species to survive, is critical. But Conservation scientists also try to preserve migrational behaviors.

No doubt, there are fragile creatures which travel south to avoid cold temperatures as well as lack of food. The Monarch butterfly comes to mind. The disappearance of flowers, and freezing cold would spell doom for them in northern climates. So they embark on a 3,000 mile journey to Mexico, or southern California. Let’s consider some other long-distance, roundtrip travelers:
*Salmon and Caribou also migrate 3,000 miles.
*Dragonflies will go 10,000 miles.
*Leatherback turtles swim 12,000 miles.
*Elephant seals and Humpback whales swim over 13,000 miles.
*For birds, Northern Wheatears and Pectoral Sandpipers fly 18,000 miles.
*Sooty Shearwaters fly from the Falkland Islands to Arctic waters, a roundtrip of 40,000 miles.
*The champion distance migrant, the Arctic Tern, flies 44,000 miles from the Arctic north of Greenland to Antarctica every year!
*And the longest nonstop flight goes to the Bar-Tailed Godwit at over 7,000 miles from Alaska to New Zealand in nine consecutive days!

An entire program could also be dedicated to human migrations including various Native American tribes, the Nenets who herd reindeer 400 miles in the Russian Yamal Peninsula, and the ancient people who crossed the Bering Strait to settle in the Americas.

As we close this session of Fall migrations, consider the words of George Eliot who wrote
the following in 1841: “Delicious Autumn. My very soul is wedded to it. And if I were a bird I would fly about the earth seeking the successive Autumns.”
