The study of recurring plant and animal life cycle events is phenology. It is the calendar of nature. This includes when plants flower, when birds migrate and when crops mature. Phenology is relevant to interactions between organisms, seasonal timing and large-scale cycles of water and carbon. Phenology is important to us for many reasons. Farmers need to know when to plant and harvest crops and when to expect pests to emerge. Resource managers use it to monitor and predict drought and assess fire risk. Vacationers want to know when the best fall colors will be or when the wildflower blooms will peak. Timing varies but we can discern patterns.

The USA National Phenology Network monitors the influence of climate on the phenology of plants, animals and landscapes. They encourage people to observe phenological events such as flowering, migrations and egg laying. The Phenology Network provides a place to enter, store and share these observations, which are then compiled and analyzed nationwide. Participants range from individual observers in their own backyards to professional scientists monitoring long-term plots. My husband and I monitor leafing and flowering of lilacs, a key species in the program.

These observations support a wide range of decisions made routinely by citizens, managers, scientists and others. This includes decisions related to allergies, wildfires, pest control, and water management.

I urge you to participate. The National Phenology Network has many public, private and citizen partners. It is a great way to become involved in a nation-wide effort to better understand our environment. All this information and much more is available at the National Phenology website, to which there is a link from our Wild About Utah website.

Blackbears

Hi, this is Mark Larese-Casanova from the Utah Master Naturalist Program at Utah State University Extension.

I have to admit that it didn’t make much sense to me that yesterday was the start of summer. While sitting in the warm sun, feeling like winter forgot to give spring a turn in the seasonal cycle, I though of the American black bear, another mammal that also probably wondered when the warm weather would finally arrive.

Black bears are native to most of North America, even into northern Mexico. In Utah, black bears are common throughout many of the state’s forests. Contrary to its name, black bears tend to be medium to dark brown in the western US, although its color can range all the way from blonde or cinnamon to black.

As black bears emerge from their winter slumber, they are particularly hungry from several months of living mostly off of fat reserves. This is an even greater challenge for females because cubs are born in January or February and survive on the mother’s milk until spring. So, when spring arrives, they are more than happy to feed on a wide variety of foods, including fruits, nuts, grubs and other insects, small vertebrates, and carrion. Bears are most actively feeding around dawn or dusk, but may feed at other times of day if they become habituated to human food sources.

Black bears have been known to attack humans, although usually very infrequently. Attacks most often happen when a black bear is defending cubs or food, or as a result of becoming accustomed to obtaining food from people.

Will the black bears be as hungry for summer as we are? It might be best to not take any chances while out exploring the mountains this summer. When not eating, be sure to carry all food, garbage, and scented items, such as toothpaste and chapstick, in an airtight plastic bag or securely store them in a vehicle or bear-proof container. I’d even recommend carrying bear spray just to be safe. And, don’t forget to hold on tight to those pic-a-nic baskets!

Wind, Hold on to Your Hat!

Graphical Forecasts – Central Rockies

Hi I’m Holly Strand.

On a recent camping trip on Utah’s Colorado Plateau, my brother and I were buffeted by strong sand-blasting winds for two days straight. Setting up camp was nearly impossible. Strong gusts ripped the tent away from us. Catching only the guylines, we flew the big green tent like a kite through the sagebrush. Eventually we pulled it down and got stakes in the ground. Unable to make a fire, we ate a cold dinner and tried to sleep –until the tent collapsed under the persistent onslaught of meteorological Furies. The next day, the sand-infused wind whipped us painfully as we descended into Horseshoe Canyon. Dust devils pursued us along the canyon floor.

Arriving home I read up on the cause of our discomfort. In simplest terms wind is caused by air moving from high to low pressure. The steeper the air pressure gradient—that is –the change in air pressure per unit distance–the stronger the resulting wind speed. Differences in air pressure are often caused by localized warming of air temperature. The warm air rises creating a spot of relatively low pressure ; then cooler air from a high pressure region rushes in to replace it.

Wind tends to blow much more forcefully near a frontal boundary. And our camp was located very close to the low pressure center of a stationary front. Although the wind was a nuisance, it was probably only blowing around 35 miles an hour. Meanwhile the record in Utah is 124 miles an hour –a wind gust measured at 11000 feet Snowbird. The strongest wind gust here in Logan was 94 miles an hour. Compare this to the highest wind on record anywhere—a gust measuring 253 miles per hour on Australia’s Barrow Island during a tropical cyclone. The record in the United States is 231 miles per hour on top of Mt. Washington in New Hampshire. Higher wind speeds than these may occur in tornadoes, but anemometers tend to malfunction at extreme speeds .

Luckily, we don’t have to worry much about tornadoes. Utah ranks very low in terms of tornado frequency. We average 2-33 a year with most of them occurring May through August. Utah tornadoes tend to be small and not last very long. Whirlwinds or dust devils are much more common. About 90% of them occur in the West Desert where there is plenty of loose, dry dust and sand to swirl around in the air.

Thanks to Marty Booth of the Utah Climate Center for help in developing this Wild About Utah episode.

Grow Native!

Fire ChaliceCopyright 2010 Annalisa Paul
Stokes Nature Center

With the beginning of summer at our doorstep, many of us look out over our green grass yards and dread the coming heat that will endeavor to turn it brown and stale. One might begin to ponder if there is an alternative to these plants that fill our yards and demand so much of our water. In fact, there is.

Utah may be a desert, but not one naturally devoid of vegetation. Many plants have evolved to live within the bounds of the climate, insect pests, microbes and soil types specific to our region. Once established, many native plants need minimal irrigation beyond normal rainfall. And because they have coexisted for eons, natives have developed their own defenses against many pests and diseases, resulting in minimal pesticide use.

Backyards, gardens, parks, and roadsides planted with native plants also provide wildlife with a “bridge” to the natural areas that remain, interspersed among our heavily developed communities. As the cornerstone of biological diversity, native plants also do the best job of providing food and shelter for our local animals. Ready to get planting? Here are two natives that would be easy, attractive, and low-maintenance additions to many Utah yards or gardens.

Littleleaf Mock Orange is a compact shrub which produces clusters of wonderfully fragrant white blossoms. In the wilds of Utah, it is often found growing in rock crevices and dry, gravelly areas, so it will likely do well in those bare, difficult parts of your yard. It is browsed by mule deer and also provides shelter for native birds.

Fire Chalice, alternately known as hummingbird flower, is a low-profile plant with bright red tube-shaped flowers. The plant’s nectar is irresistible to hummingbirds and can help attract a number of native pollinators to your yard.

As with all plants, the right native must be matched with the right spot. Thankfully, there are native plants that thrive in every habitat imaginable. And the best thing is, natives include all different types of plants from mosses and ferns to wildflowers, shrubs and trees. A little bit of research should help you find the best species for your hot, dry slope, that wet swale in the back, or the dry shade under your trees.

For those interested in learning more, the Alterniscapes Garden Tour on June 25 provides an opportunity to view gardens in Millville, Nibley and Providence that feature water-wise and native plants. For more information on native plants or the Alterniscapes Tour, please visit us online at www.wildaboututah.org.
