On a recent trip to a range of rock formations near the Sierra Nevada known as the Alabama Hills, I spotted a white-lined sphinx moth, Hyles lineata, pollinating outside of a gas station during the late afternoon. The moth’s size has earned it the common name of the hummingbird moth, making it an easy winged insect to spot, and its habitat range is wide. This moth is not a picky eater, and while it contributes to pollinating many different plants, its caterpillars are known to damage crops. The moths need the plants, the plants need the moths, and we desperately need them both.

The relationship between pollinating insects and plants is profound, speaking to a level of coexistence and coevolution that is truly inspiring. I usually think of moths as nocturnal pollinators and rarely catch a glimpse of them while feeding, so seeing this moth reminded me of their importance within ecosystems.

Moths are usually seen on flowers that provide landing platforms and with nectar deeply hidden. Soon after the white-lined sphinx sighting, we found ourselves amongst the iconic Joshua trees. The yucca is an example of plants totally dependent on the pollination of specific moth species. The female yucca moth (Lepidoptera, Prodoxidae) forms pollen balls using her mouthparts and then stuffs the ball into the stigmas of the various flowers she visits. Without this very intentional routine the yucca flower would not develop fruit or seed pods. During this process the female moth will lay an egg into the flower’s chamber which protects the egg while it develops. At the arrival of the newborn caterpillars the yucca will have developed seeds, which in turn become the caterpillars’ food source.

While watching the moth I contemplated the diversity of plants and pollinators, and considered how intertwined their relationships are. The much smaller and unassuming yucca moth uses an irregular mouthpiece to pollinate the yucca, making it a critical member of the desert ecosystem. This relationship is no accident. Unlike other pollinators that unintentionally pollinate the plants they feed from, the yucca moth caterpillars need the yucca to survive – an intentional relationship that has evolved to benefit both the plant and the insect over millions of years. The yucca’s flowers provide a source of food for many different insects, ground squirrels, and birds, each owing their existence to a tiny responsive moth.

Due to rising temperatures and water scarcity in the desert the number of Joshua tree seedlings that survive and mature is decreasing, diminishing the diversity of this unique ecosystem. Joshua trees are migrating in response to their habitat warming, dropping their seeds further northward. Only time will tell whether the yucca moth is up for the move. The rest of the desert ecosystem depends on it.

On a recent trip to Death Valley I was introduced to a member of the desert’s ecology: wild burros. New to me, not the desert, wild burros have been a part of Death Valley and the Mojave Desert landscape since the late 19th century. The National Park Service identifies wild burros as an invasive species and has made attempts to remove them in the past. They interrupt the park’s natural ecosystem, consuming large amounts of water and vegetation.

Donkeys are thought to have first been domesticated about 5,000 years ago in Egypt or the Middle East. They were introduced to the U.S. by the Spaniards in the 1500’s and became a useful pack animal to prospectors and miners. The ghost towns and relics, as well as the donkey’s, were left behind and still make their mark on the landscape today.

In 1920 the Department of the Interior identified the wild burros as a major threat to the desert and over decades thousands of burros were shot. In 1971 the Wild and Free Roaming Horses and Burros Act was created, protecting the wild donkeys on lands managed by the BLM and the Forest Service. Its creation added pressure on the Park’s Service. In the 1970s and 1980s a three phase approach was instilled to round-up, adopt out, and shoot any burros that were left. Estimates now indicate anywhere from 750 and 2,000 burros now call Death Valley home. The Bureau of Land Management sees the burros as “living symbols of the historic and pioneer spirit of the West”. I will say after seeing them from a distance, images of westward expansion and romanticized notions of the nations history were abundant.

The consequences of the burros in the landscape is a complex issue deserving to be evaluated from many different perspectives. They can be devasting to perennial grasses native animals rely upon. However, one biologist found burros can dig water wells that support a number of birds and mammals. Cottonwoods, willows, and other plants have been found to sprout from burro wells. In 2017 the Peaceful Valley Donkey Rescue began work to remove 2,500 wild burros from the Death Valley National Park and the Mojave National Preserve by transporting them to training facilities. The Peaceful Valley Donkey Rescue has relocated over 9,000 animals in 17 years. Ultimately my experience with the wild burros of Death Valley left me feeling conflicted about their presence and the ongoing methods of their removal, reflective of the complexity of untangling introduced naturalized species from the landscape they’ve established themselves into.

I’ve been helping with some final coordination items and design details for Magic Johnson Park Phase 1 A – a project I’ve thoroughly enjoyed working on. It was one of the first projects I began working on here at AHBE, and being able to follow through across the project’s many stages has taught me so much. Following the process from early concept to construction documents has been a roller coaster full of ups and downs. The project has seen many iterations; I cannot wait to see the built reality.

We’ve sketched, re-sketched, created illustrative plans, renders, study models, technical details, and drawings. Now they’ve all been boiled down into one set. As I look back at the work we’ve done, I recognize something about my own design process: how sometimes the simplest sketch can both define and reveal possibilities within a project and site.

 

As a designer very interested in graphic representation, I am guilty of being seduced by a beautiful image. A montage with picturesque aesthetic technique can determine the value placed on a site design in ways that have little to do with the potential built reality. We all know this, but the attraction is still there. Much of it has to do with what works as a composition on a 2-dimensional plane. It’s something to master, and can help create an atmosphere, communicate a mood, and describe a sense of place. This is what gets people excited about the possibilities of a project. These images carry a lot of responsibility in selling a design intent, and it is easy to overvalue final beautiful presentation graphics.

There are different layers of concentration critical in the design process. With time, I hope to become more comfortable with the act of sketching – I’m talking quick and dirty, first impression, easy and loose sketching. Sketching this way is purely about discovery and experimentation, but the process is not easy. Looking back at the design process I created for Magic Johnson Park, I realize it was the quick and dirty sketches that allowed me to communicate my design ideas most successfully. Sometimes it is the first loose sketch that gets you somewhere…only to end up in the trash moments later.

Last weekend I joined other Angelenos at March Forth!,  a fundraiser and block party sponsored by LA Walks in advocacy of safer walking for all across the city. This year’s block party was hosted in Historic Filipinotown, and included games, face painting, lessons for healthy cooking, bicycle riding, skateboarding, and environmental workshops for all ages.


The event truly prioritized pedestrians and non-vehicular modes of transit (unfortunately a rare occurrence in Los Angeles), going as far as to offer free valet bike parking for bicyclists such as myself, compliments of The Los Angeles Bicycle Coalition. It was exciting to see everyone occupy the block cordoned off from traffic, engaged by ideas to improve pedestrian life in our city.


I have to commend the energy of the volunteer organizations in attendance, as they each made the event a success. Although the focus was clearly on community health and promoting safe streets, everyone was there in unity to have some fun. Particularly memorable was a bicycle course developed to teach kids how to safely ride their bikes. I didn’t begin riding a bike in an urban environment until my early twenties, and I remember it required some adjustment, including gaining the confidence and learning the techniques to communicate with drivers sharing the streets. Ideally, one day the social agreement to share the road will be ingrained in our culture across pedestrians, bicyclists, and drivers alike.


Another organization in attendance, Ours Did, displayed evocative signs that read, “Drive Like Your _ Died Here”, offering people who’ve lost a loved one an opportunity to personalize signs in hopes of creating a deeper and personal connection with street safety.


During the event I also learned about the Vision Zero campaign, founded to eliminate all traffic-related deaths and severe injuries by 2025. Los Angeles hosts the regional Vision Zero Alliance, a citywide coalition of community based and advocacy organizations brought together to promote pedestrian advocacy across the city. It was encouraging to see the momentum already in place.

As a professional in landscape architecture, it became obvious our discipline could become more involved with policy making, community engagement, and advocacy of a safer place to walk, run, ride, and also drive. One way design professionals can participate is by increasing meaningful civic engagement through visual tools. Urban policy and planning issues may affect our communities, but they’re often portrayed in unnecessarily intimidating ways. Many policies do not encourage community participation, and in turn meaningful change never materializes in the form of construction in their environments serving the people who live there.


Design professionals can and should aid in addressing complex spatial issues associated with cultural, racial, and ethnic inequality. Organizations at March Forth! showed how to effectively use visual tools like community polls to engage the public into providing feedback about how fast vehicular traffic should be set within their community, and interactive boards inviting individuals to create their own dream street revealed what the community wants from its community. Ultimately, the more people are given the tools to promote pedestrian safety and a voice to engage in meaningful exchanges, the larger and more informed the constituency becomes…and the safer the streets of Los Angeles become for all.

It was a friend’s wedding responsible for my return to New York. I hadn’t been back since I moved away 2 years ago, and I was excited to revisit the places I once loved, including a place known as Pioneer Works, a cultural center in the community of Red Hook Brooklyn. It didn’t hurt one of my favorite bars is just around the corner.

Even without knowing which exhibitions would be on display this particular day, I dropped by Pioneer Works to stumble upon an incredibly inspiring collection of work by artist, Anthony McCall. Solid Light Works blocks out over thirty feet of vertical clearance, filling multiple rooms with haze and light installations.

A seminal figure of Expanded Cinema, McCall is well known for his “solid-light works”, a series he began in 1973 with the 16mm film, Line Describing a Cone. A volumetric form composed of a beam of projected light slowly evolves in real, three-dimensional space. McCall regards these works as occupying a place somewhere between sculpture, cinema, and drawing. Sculpture, because the projected volumes must be occupied and explored by a moving spectator. Cinema, because these large-scale objects are not static, but structured to progressively shift and change over time. And drawing, because the genesis of each installation is a two-dimensional line-drawing.

As a landscape designer I was struck by the simplicity of the forms and how successful they defined space. Some areas of the installations defined more intimate spaces. Participants laid on the ground within the projected confines of the light, some taking photos, while others just stared up in contemplation. Other areas were more open and horizontal in their projections. These became more social spaces where participants moved their hands in and out of the light. The installation focusing viewers on the interruption of the figure within space defined only by the projection of light.
