2019 Joshua Tree Bloom and Responsible Nature Photography

Joshua trees (Yucca brevifolia) are some of the most iconic figures of the southwestern deserts. While most often associated with California and Joshua Tree National Park, a tiny portion of their range extends into our corner of southwestern Utah. Not actually a tree but rather a tall gangling species of yucca, Joshua trees are frequent companions on low-elevation hikes in the St. George area, where the Mojave Desert makes its last stand before disappearing into the higher altitude mountains and valleys of the Colorado Plateau and the Great Basin.

Like many species of yucca, Joshua trees don’t flower every year, but instead only when temperature and rainfall conditions are favorable. We had yet to see a flowering Joshua tree in our three years in Utah, only the dry brown stalks of blooms gone by. This winter has been abnormally wet however, and in early March we started to notice large flower buds forming on a handful of Joshua trees (in the median of Interstate 15) that we drive past regularly. By the end of March, the bloom was in full swing! We decided to head into the Virgin River Gorge of extreme northwestern Arizona for a closer look.

Joshua trees produce truly massive flower stalks: 1-2″ feet long and densely packed with large, rubbery, cream to nearly yellow-colored petals. Perhaps even more impressive are the flower buds, which resemble gigantic green and purple artichokes in the days and weeks before the flowers emerge:

This year’s Joshua tree bloom wasn’t limited to Utah and Arizona. Throughout the Mojave Desert, Joshua trees have been flowering in large numbers, thanks to a series of wet and cold winter storms over the past few months. In fact, some Joshua trees in California were observed blooming as far back as last November. This fact may seem innocuous, but actually gives ecologists cause for concern given that Joshua trees are pollinated by just one insect: the yucca moth. Yucca moths are the sole species with the proper behavior and anatomy to pollinate the Joshua tree. Consequently, Joshua trees are 100% dependent on the yucca moth for reproduction and survival, while the larvae of the yucca moth are similarly dependent on the Joshua tree seeds for nutrition. For these symbiotic species to survive, the timing of the Joshua tree bloom must coincide with the life cycle of the moth. As climate change warms the southwestern deserts, there is concern that this could cease to be the case, as described in the linked article above. Joshua trees are a keystone species of the Mojave Desert, providing food and shelter for a host of other animals large and small. A decline in their populations would be devastating for the desert as a whole.

All of this is reason to work toward protecting our remaining stands of Joshua Trees, and a reminder to always be mindful and respectful when photographing sensitive species and landscapes. The “superblooms” of poppies and other wildflowers in the southwest over the past few months have highlighted the ecological damage that occurs when swarms of folks looking for their next Instagram photo descend en masse on delicate landscapes without regard for the environment.

Fortunately, many photographers are aware of the threat photography can pose to these beautiful environments and are working to combat the problem. I’m pleased to share that I have joined Nature First: The Alliance for Responsible Nature Photography. The goal of Nature First is to promote responsible nature photography through adherence to seven core principles:

  1. Prioritize the well-being of nature over photography.

  2. Educate yourself about the places you photograph.

  3. Reflect on the possible impact of your actions.

  4. Use discretion if sharing locations.

  5. Know and follow rules and regulations.

  6. Always follow Leave No Trace principles and strive to leave places better than you found them.

  7. Actively promote and educate others about these principles

If you are a nature or landscape photographer, check them out and consider joining. Following these principles will ensure that spectacular events like Joshua tree blooms are still around for future generations of humans and yucca moths to enjoy!

Caught Between the Seasons

Winter has arrived in the high country of Utah. Fortunately for photographers, autumn was still very much in progress when the snow started to fly. The contrast between the mid-winter wonderland and vestiges of fall color made for some great photo opportunities over the past few weeks:

Another Hidden Utah Gem: Pine Park

Tucked away at the terminus of a winding gravel road in the Dixie National Forest near the Utah/Nevada border, Pine Park would probably be a beloved national monument or state park were it located literally anywhere other than Southern Utah. We’ve been fortunate to come across quite a few places that fit this profile: stunning, unique, reasonably accessible, and—here’s the big one—empty. Places like Zion National Park may be bursting at the seams, but vast swaths of Southern Utah remain deliciously deserted. On a warm and beautiful weekend in early May, we had Pine Park pretty much all to ourselves!

Large Ponderosa Pines complement the smooth knobs of white tuff. 

The main draw at Pine Park are the spectacular rock formations carved into the Tuff of Honeycomb Rock. Tuff is a deposit of consolidated volcanic ash combined with rock, mineral, and glass fragments that forms only in very explosive volcanic eruptions. Pine Park sits on the margin of some of the most voluminous and expansive deposits of tuff in the world. Collectively, the thousands of feet of tuff scattered across large swaths of Nevada and western Utah represent a time when, for lack of a better descriptor, all hell was breaking loose across what is now the Great Basin. The Tuff of Honeycomb Rock is just a hair under 12 million years old, and thus one of the youngest deposits from this intense and violent episode of volcanism.

While the backstory of the tuff is intriguing, the real allure is the wonderland of creamy white spires, domes, and hoodoos emerging from the otherwise nondescript juniper, ponderosa, and piñon pine forest. Weathering and erosion have sculpted a masterpiece at Pine Park. In many places, the architecture almost resembles Bryce Canyon, albeit whitewashed, and with no maintained trails (several Forest Service trails wind through this area, according to the official map, but we had difficulty following them for any more than a hundred yards past the trailhead) the many pockets of eroded tuff are truly a blast to explore.

The Ponderosa’s don’t require much soil to gain a foothold in small depressions between ridges of tuff.

This species of lupine (Lupinus aridus?) seemed to love the gravelly, sandy soil produced by weathering of the tuff.

The tall, stately Ponderosas and a small stream give Pine Park a high-altitude feel, but in reality it sits at just 5700 feet above sea level, plenty low and warm enough for a plethora of wildflowers to be in full bloom during our visit:

Two white flowers with many petals and pink stamens

Bitterroot (Lewisia rediviva) are abundant on long-ago burned slopes above Pine Park, now home to open grasslands.

Everywhere!
