Smoke rises from fires in September in the rain forest of the Brazilian state of Rondônia, the region of the Brazilian Amazon that was most impacted by rampant burning this year.

At last year’s climate change talks in Poland, a little-known 15-year-old Swedish climate change activist named Greta Thunberg galvanized the talks with a short impassioned speech. At this year’s COP25 climate talks in Madrid, Ms. Thunberg, now known worldwide for her charismatic climate change activism, gave a longer and even more impassioned speech. Further demonstrating the mobilizing power of youth in raising awareness of the climate crisis—which I wrote about here for Science Talk following the Poland talks—she was named TIME Magazine’s 2019 Person of the Year. What a difference a year makes!

Rarest of Them All: New Research Using Data from NYBG and Other Institutions Finds More Than a Third of All Plant Species Are “Exceedingly Rare”

Posted inEnvironment onDecember 5, 2019 by Stevenson Swanson

Stevenson Swanson is Associate Director of Public Relations at The New York Botanical Garden.

NYBG scientist Dr. Wayt Thomas collected this Sinningia macrophylla specimen in the Atlantic Coastal Forest of Brazil, home to many rare plant species.

An international team of researchers, including an NYBG scientist, has concluded that more than a third of all plant species are exceedingly rare, making them highly vulnerable to extinction from such threats as habitat destruction and climate change.

In a study published by the online research journal Science Advances, scientists analyzed the largest compilation of global plant observation data ever assembled to determine how many of the roughly 435,000 total plant species should be considered very rare. They found that 36.5 percent, or more than 158,000 species, fall into that category.

Barbara M. Thiers, Ph.D., Vice President and Patricia K. Holmgren Director of the William and Lynda Steere Herbarium at The New York Botanical Garden, joined 34 colleagues at research institutions around the world in this landmark research project.

“Destruction [of forests] represents an attack on humanity, an affront to the sources of life, and an assured means of destroying future generations.”

—Roberto Burle Marx, “Garden and Ecology,” 1969

The Amazon is the world’s largest tropical forest, spanning nine South American countries and housing 10 percent of the world’s living plant and animal species. Its trees absorb about 25 percent of carbon emissions taken in collectively by all forests on Earth, replacing harmful CO2 with the oxygen we breathe. Recent reports indicate the number of fires blazing in the Amazon in late August 2019 is the highest on record, representing an 83 percent increase over the number of fires at the same time last year.

The recent report about the fires in the Brazilian Amazon compels us to reflect on how painful the Amazonian fires would have been to Roberto Burle Marx (1904–94), one of Brazil’s earliest and most important advocates for the rain forest and the subject of our current major exhibition, Brazilian Modern: The Living Art of Roberto Burle Marx.

A renowned landscape architect, Burle Marx was also a passionate, outspoken conservationist. His writings on environmental topics in Brazil—powerful when written a half-century ago—have a renewed, relevant resonance in 2019. For example, in Burle Marx: Homenagem à Natureza¹, he is quoted as saying, “You have to understand that it is my obligation to oppose everything that I consider an ecological crime … the sacrifice of nature is irreversible.” In 1969, he wrote: “This destruction [of forests] represents an attack on humanity, an affront to the sources of life, and an assured means of destroying future generations.”² A more powerful, fitting response to the news of the Amazonian fires could not be penned today.

At a Crossroads: Plants and the Endangered Species Act

Posted inEnvironment onAugust 16, 2019 by Brian Boom

Brian M. Boom, Ph.D., is Vice President for Conservation Strategy at The New York Botanical Garden.

The federal government recently announced plans to significantly weaken the Endangered Species Act (ESA), the most important legislation ever enacted to protect threatened plants and animals in the United States. There are currently 947 plant species and 1,471 animal species listed through the ESA. The new rules, which will take effect next month, will curtail future listings and potentially reverse a half-century of salvation in the wild. An article in The New York Times outlines the plans; most of the response and commentary has focused on animals—for instance, Carl Safina’s compelling opinion piece with statistics about triumphant saves of condors, alligators, grey wolves, and pelicans since the act became law in 1973. 

However, the new rules also have grave implications for plants.

Throughout our run of Brazilian Modern: The Living Art of Roberto Burle Marx, we’re sharing glimpses into the natural world that informed Burle Marx’s love of plants and the landscapes that he traveled through in his home country and beyond, discovering new plants and working to protect those under threat of deforestation, development, and more. He called these journeys his viagens de coleta, or “collection trips.”

IPBES Global Assessment Summary for Policymakers, published May 6, 2019

Before this week, most readers probably had not heard of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), but they certainly will know of its existence now. This United Nations group made major news this week, as reported in The New York Times, with publication of its first official report, the IPBES Global Assessment Summary for Policymakers. Among its major findings was that about one million plant and animal species are now threatened with extinction, many within decades, more than ever before in human history. The IPBES report makes an ironclad case for urgent global action to mitigate human-induced biodiversity loss before humanity crosses the fail-safe point.  

The breathtakingly dire findings of the IPBES report were captured in the title and content of an analysis by Thomas E. Lovejoy, Ph.D., “Eden No More,” published in Science Advances this week. Dr. Lovejoy, an NYBG Trustee and Gold Medal recipient, elegantly explains what is meant by ecosystem services: “those charities of nature, both nebulous and tangible, that serve as the backbone of human well-being: food, fresh water, clean air, wood, fiber, genetic resources, and medicine.”

Last month, the United Nations General Assembly declared 2021–2030 the UN Decade on Ecosystem Restoration. As the UN announcement emphasized, this declaration will provide unparalleled opportunities for job creation, food security, and addressing climate change, all of which are intertwined, vitally important concerns for the future of human society and of all life on our planet. In a recent post, I wrote about the notion of a botanical approach to mitigating global warming through a concerted, coordinated effort of ecosystem restoration, for which Dr. Thomas E. Lovejoy argued elegantly and persuasively in his recently published book Biodiversity and Climate Change: Transforming the Biosphere

The UN Decade on Ecosystem Restoration, which the Society for Ecological Restoration applauded in a statement, will provide a multilateral framework to give a botanical approach to mitigating global warming a much-needed public boost and hopefully a substantial financial investment. But how much ecosystem restoration would it take to really make a difference in terms of mitigating global warming? An encouraging answer was provided in a recent research paper presented by global change ecologist Dr. Thomas Crowther at the 2019 annual meeting of the American Association for the Advancement of Science in Washington, D.C.

Proposed legislation has been introduced in both the United States Senate and House of Representatives with the rather formidable title “Botanical Sciences and Native Plant Materials Research, Restoration, and Promotion Act.” Informally, it is known as “the Botany Bill.” If enacted, the Botany Bill could greatly support the safeguarding and promoting of native plants on federal lands and the increase the number of botanists who are dedicated to studying and protecting those plant species. NYBG is one of dozens of organizations that have endorsed the Botany Bill.
