Everyone loves a good bear story, especially around the campfire. I have accumulated many in my years- all personal and factual. I consider bears my spirit animal, as do many indigenous peoples. Bears are close kinfolk given their many human-like attributes. When the news broke that a bruin was sauntering through a Cliffside residence in Logan Utah a few weeks ago, it sparked a flood of bear encounter memories. From early years in the Northwoods of Wisconsin to recent days with my students in Teton and Yellowstone national parks, the stories continue.

Two falls ago, I helped lead 30 USU international students for a weekend campout in the Tetons. We ate our lunch at Hidden Falls behind Jenny Lake, then began hiking out. In a few hundred yards, two black bears were busily gulping mountain ash berries on either side of the trail. Most of the students had never visited a national park, and none had seen a bear outside of a zoo. What to do!

“Don’t run!” I tried to convince them, unless they pretended to be a berry, they were safe. Even as a large crowd assembled, the bears were oblivious, attacking the berries with abandonment. For a good fifteen minutes, the students were helplessly under the spell of these glorious berry eating beings.

While working in Denali National Park, I joined a small group for a back country hike led by a young seasonal ranger. She gave us bear safety training before hitting the trail. Into our second hour, in a thick patch of willows, her near panicked “bear” voice put us on alert. We slowly retreated under her direction. Once at a safe distance, we began breathing again, then scrambled up the opposite slope hoping to get a view of our alarm. There, on a grassy ledge, a large mamma griz was lying on her back sound asleep while two tiny frolicking cubs played on their snoozing mom.

I’ll conclude with an occurrence from many years back when I worked as a fishing guide on Yellowstone Lake where an adolescent black bear befriended me. It would walk several hundred yards with me from my cabin to the boat dock where I would prepare my boat for a day’s fishing. It would disappear in the forest until I finished mid-afternoon, then return with me to my cabin, where I often gave it a snack from last evening’s dinner. In the mid 1960’s feeding bears was common practice.

I was amazed how gentle and polite it was. My buddy bear learned how to open my latch door lock by lifting it up with its nose, inserting a claw, then pulling the door open. It would enter, sniff the table where tidbits of food might be found, grab the treat and rush out the door, not closing it! If no treat was found, it would amble away without incident. After a week or so, to my disappointment, it disappeared.

I have yet to see a bear in the wilds of Utah. May that day come soon!

American Pika

As I hike the high country, there is a non-bird call that always brightens my way. A mini rabbit, or rock rabbit in Jack vernacular, the pika, has been declared North America’s cutest mammal. I won’t argue with this declaration, unless it’s compared to my grandkids.

On a scramble up two gnarly peaks above Alta Ski Resort a few weeks ago, my spirits went sky high with an abundance of pika busily gathering hay for their winter larder. Their Ehhhhh! Notes surrounded us, tiny furry forms darting in and out of boulder fields while we made our way to the summits.

This was especially heartening given the warming trends, which push these little spirits beyond their limits of heat tolerance in too many locations. Pikas have disappeared from more than one-third of their previously known habitat in Oregon and Nevada. Despite this, the American Pika has not been listed under the Endangered Species Act. The pika can overheat and die within 6 hours when exposed to temperatures as mild as 78 degrees Fahrenheit.

American Pikas are famously vocal. They chirp, sing, and scream in an effort to protect their territory. They use their signature call to alert others in the colony of an approaching predator, to establish boundaries, and in some cases, to attract mates.

Pikas spend a great deal of time gathering vegetation for winter which they cure on rocks to prevent molding, then store their piles under rocks for safekeeping, occasionally moving them so they don't get rained on. Haystacks, as they're called, weigh a whopping 61 pounds on average. The timing of haying seems to correlate to the amount of precipitation from the previous winter. They appear to assess the nutritional value of available food and harvest accordingly. Pikas select plants that have the higher caloric, protein, lipid, and water content. They also enjoy their fecal pellets, which have more energy value than stored plant food, by consuming them directly or store for a later sweet treat.
Cedar Breaks National monument in southern Utah has adopted the pika as its token mammal. You can get your own stuffy who has a remarkable resemblance to the real deal. Your donation will help the Monument with its field research on the pika and other park critters.

Considering pika are mostly found in alpine and subalpine environments with cool temperatures and deep snow, I was shocked to find them occurring at Craters of the Moon National Monument in Idaho averaging 6000’ elevation. Summer temperatures at the Monument can soar to 170 degrees on the black rock surface, which would fry a pica in short order. Yet, here they are, finding relief in lava tubes and deep crevasses. Unlike their diurnal alpine cousins, they are primarily crepuscular- active early morning- late evening.

The American pika can be found throughout the mountains of western North America, from Canada to New Mexico. Of the 30 global species, only two inhabit North America, which includes the collared pika found in Alaska and Canada.

Mountain Meadows

Mountain meadows- where clouds of flowers can transport the human occupant to a state of nirvana, which enveloped my comrades and I on a recent hike in the Bear River Range of Northern Utah. I’ve experienced similar moments on many occasions from top to bottom of our meadowed state- Cedar Breaks National Monument, Mt. Timpanogos, Albion Basin in Little Cottonwood Canyon, Snow Basin, Uintah’s, Tony Grove – an endless list of bliss.

Beyond the rapture and pure joy they provide, mountain meadows are critical ecosystems- biological hotspots. They are home to unique communities of plants that cannot survive under the forest canopy. Deer and elk depend on them for forage. Predatory birds, unimpeded by trees, use meadows for hunting grounds. And a diversity of butterflies, moths, and insects rely on meadow flowers for pollen and nectar. Meadows provide an important breeding ground for insects), a key food source for many birds, amphibians, and reptiles. Meadow plants also provide food and habitat for small mammals providing an important prey base for predators.

A healthy meadow has a diverse mosaic of habitats with wet meadow and riparian vegetation. Surface water flow from snowmelt spreads out across the meadow, allowing sediment deposition. A high ground water table that is fed from snowmelt percolates down allowing stream channels to flow later in the summer. By holding the water in the mountains, the risk of valley flooding is reduced significantly. Our water delivery systems are dependent on the role that meadows play in maintaining this flow.

The health of meadows can be degraded however, where activities interrupt or alter the natural flow and percolation of water within the meadow. Mountain meadows have a short growing season with relatively shallow soil and may be very sensitive to even small changes in water availability. An unhealthy meadow is one in which the natural storage of water is reduced, the groundwater table is lowered, wetland vegetation is replaced by xeric vegetation; stream channels are incised with increased sediment transport; and soils are compacted. Another threat results from forest encroachment due to climate change and mismanagement of fire and livestock grazing.

Other human-induced factors may include trampling, roads, non-native plants, altered fire regimes, air pollutants and altered precipitation (especially the timing and amount of snowmelt). Further, identifying roads and trails that intercept, divert, or disrupt natural surface and subsurface water flow allows meadow remediation to occur.

I’ve spent many hours recreating and working in meadows from the European Alps (alps meaning mountain meadow) to the Peruvian Andes, which has vastly heightened my appreciation for these mountain jewels. None have surpassed those in our Utah highlands for unadulterated splendor! So, consider adding a meadow visit to your calendar!

Utah’s Bats

The secret service takes to the sky as we paddle our canoe into a full moonlit Bear River. Our magic sonagram device collects hidden sounds of myriad bats, as they devour tens of thousands of insects. We’re floating through Wuda Ogwa, the Bear River Massacre site now owned by the NW band of the Shoshone Nation, the original owners, who lost it to Euromerican western expansion. A grant funded project being conducted by USU faculty and students, we recorded a remarkable number of species, perhaps influenced by the hot springs cave, that served as wintering grounds for the Shoshone people. There were marked differences in bat species associated with types of riverside vegetation, part of which was the invasive Russian olive.

Utah is home to eighteen species of bats found throughout the state which roost in a variety of habitats including caves, mines, hollow trees, leafy plants, rock cliffs, and buildings. The big free-tailed is the largest in Utah with a wingspan of 17 inches weighing less than an oz. The smallest bat, the western pipistrelle, is the size of a hummingbird and weighs 1/10 oz.

Most Utah bat species are year-round residents hibernating during the winter. Some species migrate south and remain active all year while migrating species breed in the spring. Hibernating bats usually breed in the fall. In the late spring, female bats gather in large nursery colonies where their young, called pups, are born in May or June.

Bats have “slow” life history and are constrained by tight energy budgets. Energetics has emerged as a driver of extinction risk among North American bats. Some of the most wide-ranging species are now on an accelerated trajectory toward extinction as a result of disease and wind energy production. Climate change is also likely to impact many bat species with broad ranges. Urbanization and other kinds of habitat-fragmenting land use changes are also thought to be altering species distribution patterns.

Bats offer many ecosystem benefits. Some subtropic species pollinate plants, many serve as prey to other animals, and cave communities benefit from bat guano which provides nutrients.

Bats benefit humans by eating up to 100 percent of their body weight in insects each night (1000 insects/hour), providing over $3.7 billion worth of pest control each year in the U.S. and reducing the need for pesticides. Their membrane wings and echolocation have inspired technological advances in engineering. The wingsuits used by basejumpers take more than a few cues from bats’ aerodynamic bodies. Utah law protects all bat species. Additional federal protection is extended to species on the Endangered Species List.

Given many gifts bats provide for humans numerous ecosystem services, we can reciprocate by reducing outdoor lighting which disrupts their natural behaviors, avoid disturbing them, especially if they are hibernating, building a bat house, and participating in Bat Week which occurs the last week of October. It’s a time to celebrate and learn about our Utah bats!
