ASLA announces the 2021 Student Award winners. The 35 winning projects exemplify the highest level of achievement by future landscape architect professionals. The students themselves will be honored at the ASLA Conference on Landscape Architecture, Nov. 20 in Nashville, TN.
Winners each year are chosen by a jury panel representing a broad cross-section of the profession, from the public and private sectors, as well as academia. The 35 winners were chosen from 440 submissions of projects from around the world. Awards categories include: General Design, Urban Design, Residential Design, Analysis & Planning, Communications, Research, Student Collaboration, and Community Service.
“This program not only honors the tremendous creativity and passion of these future landscape architect leaders, it also highlights the extraordinary contributions they will make to communities upon graduation,” said Torey Carter- Conneen, CEO of ASLA.
To date, carbon capture and storage systems, which have sought to divert and bury carbon dioxide emissions from power plants and industrial facilities, have been controversial. Often associated with the oil and gas industry, these systems are seen as an expensive and complicated solution that may only help to postpone the inevitable shift to renewable energy. But Orca, a new facility in Iceland by Swiss firm Climeworks and Icelandic startup Carbfix, promises to de-couple carbon capture and storage from fossil fuels and instead scrub excess carbon dioxide directly from the atmosphere.
Using a set of fans and filters packed into boxes the size of 40-foot shipping containers, this new facility is expected to remove 4,000 tons of carbon dioxide from the air annually, injecting it deep into the ground, where it will eventually mineralize into rock. According to the U.S. Environmental Protection Agency (EPA), that amount of carbon dioxide equals annual emissions from around 870 cars. Climeworks hopes to remove 500,000 tons by 2030 and eventually 300 million tons a year, but this would still only account for 1 percent of global emissions. For reference: in 2020, 31.5 billion tons of greenhouse gases were emitted.
At the opening ceremony of Orca, Icelandic Prime Minister Katrin Jakobsdottir said: “this is indeed an important step in the race to net-zero greenhouse gas emissions, which is necessary to manage the climate crisis.”
Orca, which in Icelandic is phonetically the same as “energy,” is entirely powered by renewable energy. According to The Guardian, the system uses fans to push air into a collector with filters that separate out the carbon dioxide. As the filter material fills with CO2, the gas is heated to approximately to 212°F (100°C), which enables concentrated CO2 to be separated out, mixed with water, and injected 1,000 meters (3,280 feet) underground in basalt caverns, where the mixture becomes hydride of sulphur (HS2) in approximately four months and then dark grey rock 20 months afterwards. The system is expected to work well with the geology of Iceland, but it’s unclear whether it can succeed in other geologies, and what amount, type, and quality of water is required to inject and mineralize the gas.
Another issue is the comparatively high-cost of the nascent technology: about $600 to $800 per ton of carbon storage, which is much higher than the $100 to $150 needed to make the system cost-competitive without subsidies or a corporate benefactor. The companies involved believe that as they scale up their facilities, costs can be reduced to $200 to $300 per ton by 2030 and half that again by 2040.
The Washington Post states that injecting CO2 into the ground is just one way to handle excess CO2 captured from the atmosphere. Climeworks’ 15 other installations across Europe harvest CO2 into order to recycle for other uses: It can be mixed with hydrogen to make fuels. Farmers can feed their plants CO2. Soda companies can use it to create bubbles.
The United Nations Intergovernmental Panel on Climate Change (IPCC) argues that methods to actively draw down greenhouses gases from the atmosphere will be required to achieve the goal of limiting warming to 1.5°C. The International Energy Agency contends that carbon capture and storage systems will need to pull 1 billion tons out of the atmosphere by 2050 to be viable in helping to achieve that goal. While Orca may increase interest and investment in scaling up machine-based carbon capture and storage, another solution that offers so many additional benefits shouldn’t be forgotten — trees.
An average tree absorbs an estimated 48 pounds of CO2 per year, so by the time it reaches 40 years old, it has stored a ton of carbon. Given the relatively long time frame for trees to sequester carbon and the world’s more immediate carbon draw down needs, many scientists and environmental groups have called for planting vast forests at a much faster pace. The United Nations’ trillion tree campaign, supported by the World Economic Forum and American Forests, seeks to “conserve, restore, and grow” one trillion trees around the world by 2030.
Scientists are also looking more broadly at tree planting as a tool to restore forest ecosystems and store more carbon terrestrially over the longer term. A 2019 study in the journal Science found that “ecosystems could support an additional 0.9 billion hectares of continuous forest. This would represent a greater than 25 percent increase in forested area, including more than 200 gigatonnes of additional carbon at maturity. Such a change has the potential to store an equivalent of 25 percent of the current atmospheric carbon pool.”
So trees alone are also not the answer to the climate crisis, but they offer many other ecological and human health benefits beyond their ability to naturally capture and store carbon — supporting sustainable water cycles and biodiversity, providing shade, and cooling and cleaning the air. Many trees also offer usable wood: the only building material that stores carbon.
Landscape architects plan and design parks, plazas, and streetscapes, increasing the percentage of communities that are forested. A key next step is to bring the benefits of these beautiful carbon sinks to all communities in an equitable way. American Forests states that 522 million trees need to be planted and protected in U.S. cities alone to achieve tree equity.
Here’s What NoMa’s Next Park, Swampoodle II, Could Look Like — 04/13/21, DCist
“Local landscape architecture firm Lee and Associates’ design for Swampoodle II emphasizes a mix of active and passive uses. The new space has spaces that can flex for a variety of uses: There’s a green oval surrounded by benches where people can sit or kids can run around, as well as a smaller concrete space for community art or performance activities.”
Lincoln Center’s Josie Robertson Plaza Will Become a Public Park for the Summer— 04/13/21, The Architect’s Newspaper
“‘When invited to consider how the physical space of Josie Robertson Plaza could be re-envisioned to be a more inclusive and inviting environment,’ said set designer Mimi Lien, who created the expansive installation, ‘I immediately thought that by changing the ground surface from hard paving stones with no seating to a material like grass, suddenly anyone would be able to sit anywhere.'”
Dream of Connected NYC Greenway Re-Envisioned as Path to COVID Recovery — 04/04/21, The City
“Even before Biden unveiled his massive proposal in Pittsburgh Wednesday, more than 30 environmental justice, cycling, and parks groups had sent a letter to New York’s congressional delegation. Their plea: a $1 billion commitment in federal stimulus funds to build out new and link sections of existing trails separated from automobile traffic.”
How Essential Is Construction During the Coronavirus Pandemic? — 3/30/20, Curbed
“While some cities and states are shutting construction down, others are granting exceptions, particularly where it relates to the nationwide housing shortage. Meanwhile, industry groups are pushing for federal-level designation of construction as an essential business.”
“Why ferns? Because some are 350 million years old.” The world’s oldest living plants show the incredible resilience of nature’s best designs. Looking closely at ferns under a microscope, Washington, D.C.-based artist Sophia McCrocklin found that their “spores are in fact little springs,” perfectly engineered for propagation over the megaannums.
McCrocklin grew up in Kentucky. Appalled by coal companies strip-mining the landscape, she decided to fight them and became an environmental attorney. At the same time, McCrocklin explored her interest in fiber art and began showing in galleries and Ky Guild of Artists.
Her interest in ferns started about six years ago by chance. “I have always loved trees and had never thought about ferns. But I was on a hike one day in Rock Creek Park and had to go around a tree that had fallen. As I was scrambling around the log, I came face to face with a fern. It was winter and the fern was the only thing green out, so it caught my attention.”
She had been out in the forest looking for something to make in 3D, so when she got home she cut off a branch of a Boston fern in her house. She ended up replicating a stalk that was 3-4 inches long and showed people, but they were “not impressed.” She realized she needed to make a fern much larger so that people would notice it as much as they do a tree.
Someone told her that there were many types of ferns at Dumbarton Oaks Park (DOP) in Washington, D.C. Landscape architect Beatrix Farrand, who designed the space as the naturalistic companion to the formal gardens above at Dumbarton Oaks, had planted 8 types, but there were also 7 others native to the area.
After speaking with DOP Conservancy staff, including landscape designer Ann Aldrich, the park’s resident plant expert, McCrocklin started to catalogue and investigate the ferns. She then decided to undertake a series of large-scale art works, organizing them into categories: Farrand’s ferns, other native ferns, and inspired ferns, which include some of her early explorations. She later became the park’s first artist-in-residence.
McCrocklin essentially photocopies the ferns and blows them up to a very large scale. She also looks at ferns under a microscope at the Smithsonian’s US Herbarium to ensure the details of the plant scale up accurately.
In Annapolis, McCrocklin purchased junk Dacron boat sails, a durable polyster material, for around $1 a pound. She cuts ferns out of the Dacron, sews them, and inserts copper wire to support the stalks and leaflets. Color is added through acrylic paint or pencils. Spores are made of anything from mustard seeds to beads of glass. The fuzzy parts of the ferns’ stems crafted from shredded canvas fiber or sometimes cotton. “I try whatever works.”
Each is then mounted on a heavy canvas board, or otherwise it would collapse. The canvas is painted with a cherry blossom pattern, reflecting how they can be seen in spring in Dumbarton Oaks Park.
Each fern takes about 6 months and is either 4.5 feet square or approximately 2.5 feet wide by nearly 7 feet tall.
Some are more challenging than others to engineer at large sizes. Sword ferns like the Boston or Christmas fern, which have one stalk with attached leaves, are relatively straightforward.
Tassel ferns, on the other hand, are like small trees, with many branches, each with leaves. “They are very time consuming. If I had tackled tassel ferns in the beginning, I’m not sure I would have done this project,” she said, only half-joking.
After spending many years with them, McCrocklin has grown to love ferns. By enlarging them and making them such tactile works, she wants to convey how important they are.
“We easily look up at big trees because they are magnificent and awe-inspiring. We rarely look down at ferns, but the loss of these plants and the forest’s understory is the canary in the coal mine.”
She said some areas of Maryland fence out deer. The result is a “dense and lush” understory. But in D.C., where deer roam, “there is just bare ground, which is bizarre.”
“I want to make people aware that the understory is vital to the health of the forest. People need to pay more attention to the little things, as they signal the condition of our ecosystems. A forest may look healthy if it is filled with trees, but trees are really the last to go.”
McCrocklin’s exhibition, which was to be free and open to the public in early April, has been cancelled due to COVID-19 and will be rescheduled for next spring or fall. Explore her work at her website and on Instagram.
Landscape Prize Honors Cornelia Hahn Oberlander – The New York Times, 10/3/19

Coast-to-coast, AN has selected six of these can’t-miss lectures that delve into issues such as climate change, urban beautification, the ecology of memory, and more.”
In the global scramble to reduce carbon emissions, planting more trees is always near the top of the list of solutions. Pegged as a low-cost, natural, and scalable approach, projects like the Great Green Wall in North Africa, Pakistan’s 10 Billion Tree Tsunami, and New York City’s Million Tree Program raise the bar for this climate change mitigation strategy. While a new scientific study found there is untapped potential for carbon sequestration through planetary reforestation, other researchers are concerned about how growing new forests could reduce the focus on preserving existing old growth forests or negatively impact the water supply in developing countries.
The recent study published in Science, led by Thomas W. Crowther at ETH-Zürich, posits that an increase in 0.9 billion hectares (2.2 billion acres) of new forests, an amount that would cover about 14 percent of habitable land, could sequester 205 gigatons of carbon from the atmosphere. This means a forest roughly the size of the United States or China could sequester more than five times the annual carbon output of the planet.
Under current climate conditions, the Earth could support a maximum of 4.4 billion hectares (10.9 billion acres) of forests. Approximately 2.8 billion hectares (6.9 billion acres) are currently forested. This leaves 1.6 billion hectares (4 billion acres) were additional forest could be planted. The research team removed land used for crop-based agriculture or cities,”which are necessary for supporting an ever-growing human population,” leaving 0.9 billion hectares (2.2 billion acres) available for forest restoration.
Across the lifetime of these proposed new forests, the trees would sequester 205 gigatons of carbon from the atmosphere. For reference, we have released 1,510 gigatons of carbon to date (as of 2015), and some 55 percent of that has been sequestered by oceans and plants.
A sequestration strategy of this magnitude would make a sizable dent in the total carbon released into the atmosphere, but needs to be matched with reductions in fossil fuel use and other major forms of greenhouse gas emissions. The World Resources Institute (WRI) reports that 37.1 gigatons of carbon were released in 2018 alone. At this rate, more carbon will be released than can be captured by the new forests during the 50-100 years it will take for the trees to mature.
The research team is correct in asserting that global tree restoration is “our most effective climate change solution to date,” but some researchers fear that addressing one warning light may turn on others.
For example, focusing on planting new forests instead of preserving old growth trees can have negative impacts. Large, old trees, which support greater biodiversity and sequester more carbon than younger trees, are “declining in forests of all latitudes,” according to a 2012 study. Old growth forests are able to sequester more carbon than their younger counterparts because they are still rapidly growing and increasing their carbon storage capacity. Preserving older forests while implementing massive reforestation efforts would yield the greatest potential for carbon capture and forest ecosystem health.
Protecting large old trees is an important part of the climate mitigation effort, and something that landscape architects working at a variety of scales can support. Every reforestation effort, even in an urban park, should take into account existing trees and the role they play in ecosystems.
Trees need water to thrive. The renewed call for mass reforestation across the globe has some researchers worried about the effect this will have on local water supplies.
In a recent study published in Nature, Jaivime Evaristo and Jeffery J. McDonnell examine the impact of forest management practices, such as deforestation, conversion into agricultural land, regrowth, and afforestation (growing new forests), on the availability of water in watersheds. The study develops a vegetation-to-bedrock model, which considers the geology of a given region in relation to its capacity to store water.
The researchers found that deforestation and conversion of forests into agricultural land increases the volume of water present in almost all watersheds, while regrowth of forests and afforestation reduced the volume of water. “The vast majority of the water loss in afforested and reforested areas is from evapotranspiration, which is a combination of evaporation from soil and other surfaces and transpiration from plants.”
Afforestation and deforestation have the largest impacts on streamflow in watersheds. Deforestation can cause flash floods, but reforestation can lead to droughts.
The data also shows the percentage change in tree cover is correlated to the socio-economic status of a country. Developing and least developed countries lose the most tree cover while developed and emerging countries lose the least. The researchers think this correlation between tree-cover change and economic status “suggests that countries that have infrastructure in place for capturing and storing water may be least vulnerable to possible water supply shortages associated with planting schemes.”
Furthermore, the research team concludes the magnitude of a forest management technique is correlated with the water-yield response. Reforesting nearly 14 percent of the landmass is a massive change, one that would surely have consequences for local communities and ecosystems.
The researchers recognize their streamflow analysis could be used most prudently “for re-calibrating the cost-benefit matrix of climate change mitigation schemes (for example, planting and removal) in different geo-climate regions around the world.”
The Architecture of Trees was first published by Cesare Leonardi and Franca Stagi, two versatile Italian furniture, landscape, and architectural designers, in 1982. This “scientific tome” and “original ‘labor of love and obsession'” has been re-issued by Princeton Architectural Press in all its arboreal glory.
The book features 212 trees species depicted through 550 intricate quill-pen illustrations, each drawn to 1:100 scale. A handy paper ruler is included to help readers better understand the full breadth of these beauties. Each tree is depicted with and without foilage, showing summer and winter forms. The shape of each tree’s shadows and the hues of their seasonal color are also vividly conveyed.
According to an introduction to the new edition by Andrea Cavani and Guilio Orsini, curators of the Cesare Leonardi archive, Leonardi studied at the University of Florence, which encouraged a “liberal interpretation of the discipline of architecture, an interpretation that abandoned schematic rationalism and instead was open to visual art, design, landscape, graphic design, communications, philosophy, and sociology.”
In Florence, Leonardi interacted with trees he didn’t recognize. “Their sizes and shapes impressed him, and he felt ‘more drawn to them than to architectural forms.'” While creating a landscape design for a new city park in Modena, he realized that “it would be impossible to design a park without a deep understanding of its elements, meaning trees.”
But he found that just reading about trees wouldn’t cut it; he needed to more deeply understand them. In the areas surrounding Florence and Modena, he “studied specimens, photographed them, and took note of their names and dimensions; and, then, with an eye to using them in his plans, he drew the trees in India ink on transparent film, using photographs for guidance and working on a scale of 1:100.”
Drawing, Cavani and Orsini argue, enabled Leonardi to isolate the tree from its surroundings, focus on its architectural elements, and clearly depict the features that make a species unique. Over time, Leonardi found that climate, exposure, and soil conditions impacted the growth rate and character of specimens, so he accommodated for those differences, too.
Cavani and Orsini note that The Architecture of Trees wasn’t just a result of tree appreciation, but used to support a series of landscape projects in Italy, including Parco della Resistenza in Modena, swimming pool complexes created in Vignola and Mirandola, and a study for the expansion of the Modena cemetery.
The tree studies were also brought to the design of Parco Amendola in Modena, which opened in 1982. Leonardi and Stagi chose trees based on their “size, shape, shadow, and their changing colors over the course of the year.” A 40-meter (131-foot)-tall sundial tower was designed to “illuminate the center of the park at night with a multiple rotating projector that completed one full turn every hour, creating shadows that morphed continuously.”
Those shade studies are included in the beginning of the book, followed by a color analysis, and the drawings of the trees themselves, which are organized by botanical families, genera, and species. At the end, detailed drawings of tree elements — branches and leaves — are included with relevant notes about how the trees change over their lifespan, their fruit, their smells, and planting notes.
While the publisher honors the original edition’s organization, moving back and forth between the color analysis, drawings, and detailed drawing notes simply using plate numbers and trees’ Latin names can be a chore. It takes some digging to find the English or common names as well.
In the forward, Laura Conti writes that trees are increasingly critical to making cities more humane and resilient to climate change. And urban leaders need to adopt policies and regulations to enhance the quality of green spaces.
But to actually design and build beautiful and functional urban green spaces, landscape architects and designers must first understand the form and nature of trees, which are inherently malleable. “If man is going to ask trees to help him survive in this prison he has constructed, he cannot simply rely on that plasticity, but must acquire information about the characteristics that each tree inherently assumes in an area’s climate.”
“Competent” landscape architects then naturally take into account “a tree’s size and shape, the pattern of branch growth, the look of leaves in different seasons, and the amount of shade it offers.”
These timeless botanical drawings help us see the aesthetic value of trees themselves — complex, living objects that define the quality and character of any designed landscape.

“On a spiritual level, it’s about preserving the interconnectedness of all living things, the tapestry of life. Some small creatures may seem insignificant, but everything has a purpose.”
In Sub-Saharan Africa, where Goodall has spent her career researching chimpanzees, our closest living relatives, forests are rapidly disappearing. According to the World Wildlife Fund, some 91,000 square kilometers of forest, an area three times the size of Belgium, has been lost since 1990. Deforestation has been caused by population growth, which has led to the expansion of farms and cattle ranches, and international logging companies.
Goodall remembers cruising over Gombe National Park in Tanzania in a small plane in the early 90s and being shocked to discover the extent of the deforestation near a zone where she was researching chimps. Local farmers had been cutting down the forest to plant crops, but soon the soils became overworked and infertile, so they would cut down more forest, repeating the cycle.
Conservation organizations and European governments have been purchasing vast swathes of the tropical rainforest in South America in order to protect it. But Goodall said in Africa, “purchasing land is usually not a solution. Instead, partnerships with local communities are key.” Communities near forests must be educated on more sustainable and intensive farming techniques that enable them to grow more food while also restoring soil fertility. Communities must have enough food and income if we expect them to protect forests.
The ever-increasing demand for beef is also threatening the world’s remaining forests. There are now some 1.3-1.5 billion cows on Earth that need to be fed immense amounts of grain. Goodall said “more grain feeds animals than people.” All that grain requires unsustainable amounts of land and water. One analysis found just a single pound of beef requires some 1,800 gallons of water if the entire food production cycle is considered.
For Goodall, vegetarianism is then critical to saving the forests. We must stop eating beef, as “we need forests for our spiritual and psychological development.” And we must preserve forests as habitat for Goodall’s beloved chimps and all the other vitally-important tree and animal species.
Goodall travels some 300 days a year in an effort to create hope for a more sustainable future. She has witnessed amazing restoration projects, often including indigenous people. Indigenous people are key to forest conservation because “they understand forests and don’t overpopulate, anymore than chimps do.”
She added that planting trees through massive reforestation efforts is prohibitively expensive in most developing countries. “Leaving land fallow works best; the trees come back.”
Lastly, this global environmental phenonemon reiterated that people need to change their diets and eat less beef. Baldwin asked: “Are people ready for that?” Goodall believes so. “Even in Texas, you can now easily find a vegetarian restaurant. You aren’t looked at like you are some weird freak, some tree hugger.”
In reality, a recent Gallup report found just 5 percent of Americans are vegetarian and 3 percent are vegan. In contrast, some 29 percent of the population of India is vegetarian.
In a related session, Carole Saint Laurent, deputy director of global forests and climate change with the International Union for the Conservation of Nature (IUCN), said her organization is helping countries achieve the Bonn Challenge, which aims to restore 160 million hectares of degraded or deforested land by 2020 and 350 million hectares by 2030. (For reference, 150 million hectares is about four times the size of California).
Today, some 7.6 million hectares are lost each year to cattle ranches and farms, and pressures on forests will only increase as the Earth’s population hurtles towards 10 billion. To protect forests for the long term, IUCN and other organizations have launched the 30 x 30 Challenge, which has brought together many important players across sectors. The goal is deeper economic, environmental, social, and cultural changes in land use.
Naoko Ishii, head of the Global Environment Facility (GEF), which steers billions towards climate and environmental projects in developing countries each year, believes the 30 x 30 Challenge can “transform global food and agricultural systems.”
GEF will be putting a half billion dollars to this effort over coming years. “We need to produce 300 percent more food with population growth. This production expansion is a huge challenge for forests, and the problem is particularly acute in Africa.” Solutions will require more “science-based planning at the landscape level” in order to “get out of fragmented, small-scale actions.”
