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.

Trouble with Tumbleweeds

Immortalized on the sets of old western movies, the tumbleweed has long been a classic symbol of the rugged, wide-open landscapes of the American West.  As a result, we can all easily recognize the spherical skeletons when we come across them caught on underbrush or piled up on fence lines here in Utah.  But this archetype is not an accurate representation of typical western United States or Utah flora, because tumbleweed– or Russian thistle –is an invasive weed.

The story begins in the late 19th century, when South Dakotan farmers reported seeing an unknown plant growing in their croplands.  Years later, it was identified as Russian thistle, scientific name Salsola tragus, a native plant of Russia and the Eurasian steppes east of the Ural Mountains.  It had been accidentally brought to the United States in a shipment of flaxseed.  By the time the U.S. Department of Agriculture published its inquiry into the plant in 1894, about 20 years after the plant’s introduction, 35,000 square miles of land had become “more or less covered” in Russian thistle.  Since that time the plant has spread into every state except Florida and Alaska.

So what is the problem?  Russian thistle, despite the nostalgic connotations of the old west it inspires, is a pest.  It easily takes root in disturbed or bare ground, moving in before native species are able to establish.  Drought conditions like those we have had in recent years only promote the plant’s proliferation.  The dryness hinders the growth of crops and native species, while the Salsola seed requires very little moisture in order to germinate and grows in where the crops and native species otherwise would have.  This can have deleterious effects on cropland and natural ecological functioning. Not to mention the wildfire risk the dry plant debris poses.

Salsola’s sheer numbers have also turned into more than just a nuisance.  Each plant may bear some 250,000 seeds that can be spread across miles as they drop off the rolling tumbleweed.  Consequently, we see images like those from Colorado earlier this year depicting piles of tumbleweeds filling streets, covering cars, and climbing the walls of houses.  In one instance, a windstorm clogged a town in New Mexico with 435 tons of the weed.

Utahns have yet to experience the full effects of this plant’s troublesome nature, but this does not mean we are immune; Russian thistle has been reported in every county of the state.  Luckily, for those fighting this plant’s advance, technology and research are on our side.  Several biological control options– from insects to fungal pathogens –are being tested as methods of natural Salsola population suppression with encouraging results.  But, all in all the management principles have not changed much since 1894: prevent the production and dispersal of seed across all infested areas.

Weedy plants of old world origin threaten natural areas throughout the United States. An invading plant colonizing a completely new area often lacks the insects, diseases and herbivores that kept it in check back in its native homeland. If the introduced plant grows and spreads vigorously, it can spell disaster for the native inhabitants of its new home. With no natural controls in place, it may outcompete native plants and greatly diminish biodiversity. Disturbed or degraded habitats are most susceptible to invasion by Eurasian weeds.

Utah hosts many invasive weeds causing problems throughout the state. One Eurasian grass threatening sagebrush habitat and rangeland is medusahead rye. Medusahead rye probably came to the United States as a seed contaminant in the 1880’s. The seed head is heavy, so on its own, cannot spread far. But the seeds do have a ticket for dispersal: tufted hairs which cling and readily attach to livestock and vehicles. Once on site, medusahead grows vigorously, crowding out other plants.

Medusahead tissue contains abundant silica which slows its decomposition. The accumulation of dead material forms a dense thatch that smothers other plants. This dry thatch layer can also fuel wildfires. In addition, the gritty silica makes medusahead unpalatable, so both domestic and wild grazing animals avoid eating it. Infested ranches can lose 3/4 of their grazing capacity.

Sage grouse are already in trouble due to habitat loss, and medusahead has invaded more than 10 million acres of the sage brush that sage grouse call home. Once invaded by medusahead, sagebrush habitat is very difficult to restore. The best hope is to prevent or at least hinder its spread through management using controlled burns, herbicides and careful grazing. Non-native, invasive plants are among the most serious threats to our natural world and the habitats and species we know and love.

Hi, I’m Holly Strand from Utah State University’s Quinney College of Natural Resources.

Algae and moss are plentiful in and around Utah streams and lakes. But lots of people confuse these two kinds of plants. So let’s sort out what each one is.

First, both moss and algae are ancient plant forms that are commonly found in wet or moist places. As primary producers both algae and moss use sunlight to fix energy, giving off oxygen as a byproduct.

Neither algae nor moss has a vascular system to transport water so vertical growth is not their strong suit. Rarely more than an inch tall, a cushion of moss is really a tight cluster of individual moss plants. Bunching helps support the individual moss structures and helps conserve water. Meanwhile, algae comes in many forms, from microscopic one-celled diatoms to huge colonies of giant floating mats, or long flowing filaments. Algae also comes in many colors, such as green, gold, brown and red.

So where are they found? Moss loves shade. Look for it in the deep shadowy gorges and box canyons of the Colorado and Green Rivers. It also thrives in drainages off cliffs and around springs. Damp meadows, tree bases, bogs, and pond edges make great moss habitat. You will seldom find moss in saline environments. Some moss species live submerged in water but most live on land. With the sun-loving algae, the opposite is true—most live in water but some species will grow on damp soil and on the shaded sides of damp walls and trees.

Moss grows very slowly and lives a long time. So it needs a stable environment in which to grow. In contrast, algae is extremely fast-growing. A generation might last from one to several days. Algae is also extremely sensitivity to chemical, temperature and light conditions. Therefore, the presence, absence or quantity of algal species can be a useful indicator of ecosystem health. For instance, your aquatic system is probably in pretty good shape if a number of different species are flourishing. However, if the water is dominated by one or just a few fast growing species and the water starts to turn color—usually green—the system is seriously out of whack. Called algal blooms, these dramatic explosions of growth are usually the result of excess phosphorus or nitrogen runoff in the water.

During blooms the algal mass produces lots of oxygen during the day, but it consumes more than it makes at night. Further, more dead organic material is produced which eats up more oxygen. The result is a severe oxygen deficit. Resident fish, insects, and plants are deprived of oxygen and end up suffocating.

Go to www.wildaboututah.org for links to information on how to prevent algal blooms.

Thanks to 4th grade classes of Fallon Farokhi and Andrea Bostwick for their interest in moss, algae and water quality. Funded by an environmental education grant from the EPA Region 8, the 4th graders investigated and reported on water quality issues in the Bear River watershed. Also, thanks to Wayne Wurtsbaugh and Chuck Hawkins of Utah State University’s College of Natural Resources for their expertise in writing this piece.
