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

It’s almost Halloween so I’d like to tell you about an unusual creature that has given many people a fright. It has a shiny oversized body with long spiny appendages. Dark eyes stare disturbingly from a smooth, bald head. It eats both living and dead matter. And sometimes it engages in cannibalism.

It’s a zombie you may be thinking! But no; Continue reading “Cricket or Cootie?”

Kokanee Life Cycle

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

A highly compelling mating drama is taking place now in select mountain reservoirs. Utah’s colorful kokanee salmon are at the very peak of their upstream migration. Yearning to find the gravel bar in which they were born, these fish follow their noses. For the smell of that gravel birthplace–and the surrounding stream–is imprinted in young kokanee brains. Biologists call this smell the “home stream olfactory bouquet.”

Once a female kokanee is satisfied with the surrounding “olfactory bouquet,” she digs a nest in the gravel with her tail. As she digs one or more of these nests, individual males will try to guard her in order to secure their paternity. Part of the spectacle of kokanee-watching comes from the darting and biting and jostling among males attempting to get access to females. Once the eggs are laid and fertilized the female covers them with gravel.

This is the end of the line for the new parents. Within a few days of egg laying the female will die. And the male will follow soon after. Expired fish provide food for predators and scavengers such as gulls, ravens, and coyotes. Any leftover salmon will decompose and fertilize the stream waters, leading to plankton growth, which—in turn–will nourish the new crop of young salmon.

In Utah, kokanee eggs hatch between November and January. The tiny new salmon will spend their first weeks of life hiding in the gravel feeding off the remains of their egg yolk sack. After a few weeks they will emerge from the gravel to feed on plankton. By spring, these youngsters—called fingerlings– will be an inch and a half long. During spring runoff the fingerlings are swept downstream until they spill into a lake or reservoir. Now they will stay here in the open water for 2-4 years, feeding on zooplankton until they reach maturity.

For these first stages of life kokanee are dark to greenish blue on the head and back, silver on the sides and silvery or white underneath.
But at summer’s end, the spawning salmon will undergo their astonishing transformation. The males’ bodies will turn a bright red-orange. Their shape will change as well. They will acquire humped backs, hooked jaws, and elongated teeth. The females also turn red although the color may not be as striking. By late August both males and females are congregating at the mouth of the spawning stream preparing to embark on the final–and most important–mission of their lives.

For more information and locations for kokanee viewing go to www.wildaboutUtah.org. You’ll also see a video of kokanee spawning in the Little Bear River*, the main tributary of Porcupine Reservoir.

For Wild About Utah, I’m Holly Strand.

* Many people call this Cinnamon Creek. However the Little Bear River feeds Porcupine reservoir. Cinnamon creek joins the Little Bear, as a tributary, a little bit up stream and East of Porcupine reservoir.

Where to see kokanee salmon spawning (adapted from Utah Div. of Wildlife Resources website)

The Kokanee spawning runs in Sheep Creek, Indian Creek, Strawberry River and the upper East Fork Little Bear River occur in late August through early October. Flaming Gorge Reservoir has a late-season spawning population which spawns in the Green River and along the shores of the reservoir in late October through November.

Sheep Creek is in northeastern Utah, about six miles south of Manila. The viewing site is at the Scenic Byway turnout where Sheep Creek crosses under state Route 44.

Porcupine Reservoir: Just pass Avon, turn left (there’s a sign) and head east to the reservoir. Pass the dam and follow the shelf road past the end of the reservoir. There will be a wide level area where you can park and walk down to the Little Bear River to see the salmon.

Sept. 22 is Kokanee Salmon Viewing Day.at the U.S. Forest Service visitor center at Strawberry Reservoir. Utah Div. of wildlife Biologists will be on hand to show you the salmon and answer any questions. https://wildlife.utah.gov/dwr/news/42-utah-wildlife-news/906-see-kokanee-at-strawberry.html Even if you can’t make it to this event, salmon should be visible in the Strawberry River, and other tributaries to Strawberry, from now until the first part of October.

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

It’s fire season in UT. The hill slopes have turned a parched yellow-brown and the trees look thirsty and flammable. As of Aug. 13, there were 7 fires burning across the state.

One of the first questions that arises with any wildfire is “What started it?”

And I wonder: “How in the world would you figure this out given the destruction that a fire leaves in its wake?”

The first step toward identifying a cause involves finding the exact spot where the fire started. To do this, investigators look for witnesses. And having information on wind direction for the duration of the fire helps a lot. But even in the absence of these, the fire itself leaves clues regarding the direction of movement. And if you know the direction of movement, you can trace the path backwards to the ignition site.

For instance, on a tree or post, the side exposed to the oncoming fire will show deeper charring, more loss of wood and more white ash than the unexposed side.

However the leeward side of a tree may have the highest char mark. That’s because as strong winds blows the fire past a tree, the flames are drawn into the eddy zone on the leeward side and extend higher up the trunk. Still, the deeper char will be on the side facing the advancing flame. So to get to the area of the fire origin, you’d want to follow direction indicated by the most damaged tree face.

When green leaves of shrubs or trees are scorched, they tend to become soft and pliable and bend in the direction of the prevailing wind. After the fire passes they become fixed in this position as they cool, still pointing in the direction of the wind. So the opposite direction of the pointing leaves will take you closer to the fire origin.

Another thing that generally helps fire investigators is the fact that all fires need time to achieve their maximum spread rate/intensity. A newly ignited fire may take 30 min or more to ramp up. As a result even with high intensity fires, the area of initial ignition will show relatively less damage; upper foliage and branches may even remain intact.

Once the area of origin is identified, investigators look for the human or natural source of the blaze. Footprints, tire marks or evidence of a campfire are noted with interest. Nearby power lines, railroad tracks or electric fences may have provided the initial spark. Investigators often end up on their hands and knees searching for things such as cigarette parts, ignitable liquid residue; bullets or empty shell casings.

If lightening is a suspected source investigators look for strike marks or splintered wood fragments. Lightening can also leave a glassy residue, called a fulgurite, when the strike melts sand on the ground or on vegetation.

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

You don’t have to be in Utah to appreciate some of its treasures. Examples of Utah natural history can be found in museums around the globe. The last time I was in Washington DC, I explored the collections of the Smithsonian Museum of Natural History. There turned out to be a whole lot more Utah stuff than I ever imagined.

Many would consider dinosaurs to be our most illustrious museum export. Indeed a 90-foot long Utah diplodocus is the centerpiece of the museum’s Dinosaur Hall.

Not far away is an amazingly intact Camarasaurus from Utah’s Dinosaur National Monument. Its fossilized bones remained in position for over 150 million years. So beautifully and naturally preserved, it still rests on part of the sandstone block in which it was found.

Only a tiny fraction of the Museum’s collections are on display. The vast majority of its 126 million specimens are in drawers, vaults, and freezers. These items are meticulously cataloged and preserved and they serve as primary reference materials for researchers around the world. I found many 1000s of cataloged items for Utah plants, mammals and birds. Less abundant, there are still 100s of records representing specimens of our amphibians, reptiles and fish.

If you poke around in the collections databases you are sure to find something of interest. I found records of some 300 Utah plant specimens collected by Lester Frank Ward, a botanist who worked for John Wesley Powell on his western expeditions. Powell also contributed to the Smithsonian’s collection of flora and fauna. I found 8 bison skulls and one grass species, but there is probably more.

There is the skull and partial skeleton of a grizzly killed in Logan Canyon. Not Old Ephraim–his skull is here in Utah–but another one killed the year before.

In 1950, a meteorite struck a driveway just a few feet from a Box Elder County woman. A few years later, the meteorite was donated to the Smithsonian. But not before it was enhanced by local schoolchildren using crayons of various colors.

The museum’s mineral collection contains 1000s of Utah specimen, some with very strange names : I found Beaverite, Rabbitite Englishite, Coffinite, Psuedowavellite, Cristobalite, Alunite, Apatite and even Bieberite. As in Justin, I guess.

Anyway, you get the idea. The Smithsonian collections form the largest, most comprehensive natural history collection in the world. And Utah is a prime contributor of both collection items and the stories behind them.

By the way, not only are Utah things in the Smithsonian, but there are also Smithsonian things in Utah.

For example, the Henry Mountains in south central Utah were named after the first Secretary of the Smithsonian Institution Joseph Henry.

Another example is Smithsonite–or zinc carbonate–which was first identified by James Smithson in 1802. The very same Smithson left his fortune to the United States government, directing that it be used to create the Smithsonian Institution. The mineral Smithsonite has been found in Tooele and Washington Counties.

Lastly, there’s Smithsonian Butte. When the Powell Expedition traveled through the Zion area, geologist Edward Dutton named the Butte after the expedition’s most generous sponsor. Smithsonian Butte Road is a designated national backcountry byway, crossing over the Vermilion cliffs between Utah 9 and Utah 59.
