Tiger Salamander Ambystoma tigrinum Courtesy Andrey Zharkikh, Photographer License: Creative Commons 2.0Tiger Salamanders, named for their bold black-and-orange stripes, are Utah’s only salamander. Secretive inhabitants of our forests, streams, and lakes, these amphibians are rarely seen. Tiger Salamanders spend most of their year underground, in moist burrows beneath logs and among tree roots. They come to the surface just once a year, emerging at night in the early spring to trek across the snow to newly-thawed wetlands.
Many people see Tiger Salamanders only when one accidentally falls into their window well. About 6 inches long, with a 6-inch tail, they are often mistaken for lizards even though they are more closely related to frogs. This is more obvious when you look at a salamander’s aquatic larvae, which hatch from tiny, shell-less eggs that resemble caviar. At first, they sport gills and have only tiny limbs. Usually, they metamorphose after about 2 ½ months, transforming into boldly-barred adults. Occasionally, if wetland conditions are safe, they can mature in their natal pond, becoming juvenile-like adults called paedomorphs, which can breed but resemble gigantic larvae.
Tiger Salamanders select very particular wetlands. They particularly look for bodies of water that don’t have any large, predatory fishes that would eat their eggs. Well-known examples of breeding sites in Utah include Lake Solitude in Big Cottonwood Canyon, Tony Grove Lake in Logan Canyon, and the aptly-named Salamander Lake in Stewart Canyon on the northeast slope of Mt. Timpanogos.

St. George Winter Bird Festival Courtesy St. George CityI spent 2 gloriously warm days in Dixie where I attended the Winter Bird Festival, a grand event by any measure! I also had the good fortune of discovering “Citizens for Dixie’s Future” (henceforth CDF) which has taken on the onerous task of brokering piece between a surging population and the regions limited natural resources. Water topped the list, especially the Lake Powell Pipeline proposal. So I did a bit of reading from CDF’s well stocked library.
It soon became apparent that this multi-billion dollar project needs closer inspection on cost vs benefits. The costs must include not only dollars, but some unintended consequences such as continued urban sprawl in a super sensitive Mojave Desert ecosystem with an abundance of plant and animal life that I became more aware of through an excellent WBF presentation by naturalist educator Marshall Topham on the biodiversity of Washington County.

Located at the confluence of 3 major biomes- Great Basin Desert, Mojave desert, and the Colorado Plateau intersected by numerous rivers and the towering Pine Valley Mountains, Washington County is a wildlife mecca with over 350 species of birds listed, an excellent indicator of its natural wealth.
So my naturalist instincts and a propensity towards frugality led me to look for pipeline alternatives.
I found conservation to be the most obvious and least expensive alternative. In 2009, Washington County was at or near the top in the West for per capita water use at 294 gallons per day. In dramatic contrast Tucson was 161 and golf course and fountain studded Vegas at 222. If the county was to set a goal for 1% reduction in water use per annum, it would negate the need for the pipeline according to CDF.
We notherners in Cache County are being threatened with a similar situation. Our Bear River which supplies 60% of the surface flow into the Great Salt Lake and is the primary source for the Bear River Migratory Bird Refuge is under scrutiny for multibillion dollar reservoir development to serve the Wasatch Front. In addition to the hefty price tag, this has very serious implications for loss of prime agriculture land and high value wildlife habitat.
The following conservation practices are taken from the CDF.
• Providing rebates for efficient indoor water fixtures and outdoor landscape conversion
• Adding native, drought tolerant landscaping in new developments (and converting old)
• Implementing an increasing rate structure to signal conservation to the customer
• Conservation programs must include numeric targets and performance measures
• Updating building codes with more aggressive plumbing and appliance standards
• Increasing education and awareness about reducing peak water use.
• Implementing smart growth principals and preventing sprawl
An additional conservation possibility being explored by some USU folks is restoring healthy populations of beaver to the Bear River Watershed. This has potential for water storage rivaling planned reservoirs not to mention the supurb wildlife habitat created as a bonus. A question for the Dixie folks- how are the beaver populations in the Beaver Dam and Pine Valley mountains fairing?

The American robin with its abundance, red breast, and loud song is one of the most recognizable backyard birds in North America. For many of us the robin – or Turdus migratorius – is also thought of as a herald of spring. So why is it that we still occasionally see them in our wintry Utah backyards?
Seasonal bird migration can be triggered by a number of things, but the two main drivers are food supply and nesting habitat. In spring and summer the birds move northward to take advantage of insect hatches, budding plants, and the plethora of nesting sites. Then, as food sources dwindle in fall, the birds move southward to areas where the necessary resources are still plentiful.
The distances birds migrate in order to access these resources can range widely. Therefore, birds are generally categorized as being short-, medium-, or long-distance migrants. Robins are considered short-distance migrants. While their range spans all of Canada and the United States extending down into Mexico, most robins do not travel far from their breeding grounds in winter and may not leave at all. Only the populations that breed and reside on the edges of this range will migrate seasonally.
The robin’s varied diet and behavioral adaptability are the primary reasons these short-migratory or non-migratory patterns are possible. Robins are preferably ground foragers, feasting on insects and earthworms in the spring and summer months. Yet, during the fall and winter, robins eat a fruit-based diet. They track this seasonal food source in flocks, abandoning their summer individualistic and territorial behavior. These flocks – or roosting aggregates – also help them survive the cold winter temperatures. As a result, robins are able to cope with the ground freezing, the disappearance of their preferred food source, and the harsh winter weather.
Returning to our original question: is the American robin truly a sign of spring here in Utah? Is it strange to see this bird in our backyards during the winter months? The simple answer is no. Robins can be found year round almost anywhere south of Canada. While they may migrate nomadically, staying or leaving areas as weather and snow cover affect their food supply, there could be some keeping us company in Utah all winter.

This morning I spent some time skiing up Smithfield Canyon in the Uintah Wasatch Cache National Forest. Growing up in Michigan where public land was hard to come by, I have come to enjoy our “commons” where I’m not trespassing on posted private land, or required to pay a fee before entering.
With the Oregon Bundy-Hammond event taking center stage, it has forced me to do some reflecting on what is right and what is wrong regarding our public lands.
To begin with, I’m biased in two ways- both for the land and for the ranching culture- I have deep affection for both. In my 11 seasons as a Wilderness Ranger for the Logan Ranger District of the USFS and 6 seasons with the National Park Service, I have become well aware of how our public lands are managed- the good, bad, and the ugly. On our national forest the primary issue I was confronted with was livestock grazing. The damage done by cattle and sheep was significant, plus predator control seriously interfered with how natural systems operate in balancing herbivores with their forage supply. Health of the land was always of paramount concern, but due to forest managers having very limited resources, best practices for maintaining healthy ecosystems and watersheds was compromised.
Regarding the livestock industry, it excites me to see real cowboys on horseback rounding up their animals- the romance of the west. I would love to join them. Conflicting with these feelings is my relief that the land will begin to heal from damage that often occurs when utilizing sensitive areas unsuitable for these animals, especially in large, concentrated numbers. And as a back country recreationist, I prefer elk, moose, and mountain sheep, to domestic stock and the artificiality they represent.
There are many examples of ranchers that manage their livestock well, and place them where little damage occurs. There are even ranchers who are willing to sacrifice some of their animals who realize the value of large predators in maintaining healthy ecosystems.
Do I support the Bundy takeover, or the Hammonds who violated the Bureau of Land Management laws in numerous instances? A resounding “NO!” in both cases. But I do wish them well in finding a way to maintain their ranching operations- perhaps by adding eco and/or cultural tourism or renewable energy options to provide additional income. Recreation and tourism has become our largest industry, contributing billions to the economy. More recently, renewable energy has manifested astronomical growth in the forms of geothermal, wind, and solar. Further, well managed rangelands can help remove, or sequester, carbon dioxide from the atmosphere- another potential market.
In the end, I wish both well- restoring health and access to our public lands; and preserving a flourishing ranching culture.
