My recent post on Science Talk focused on the importance of planning and executing a coordinated, worldwide scaling-up of ecosystem restoration efforts in order to maximize the potential role of plants in mitigating global warming. At least as important as ecosystem restoration is the need to safeguard the quantity and quality of existing intact ecosystems. Indeed, in a recent report, larger trees were shown to be more efficient at capturing carbon than smaller trees, so mature trees in healthy ecosystems are essential to the efficacy of a botanical approach to mitigating global warming. Another recent report, suggesting that as the climate warms, plants will absorb less carbon dioxide, reinforces the urgency of restoring ecosystems and protecting natural areas.

NYBG scientists are helping to safeguard protected natural areas by documenting their plant diversity and sharing that information with land managers and policymakers. For example, Associate Curator Benjamin Torke, Ph.D., is leading one such research project in Brazil’s Tapajós National Forest and nearby Amazonia National Park, discussed in a previous post on Science Talk and profiled in greater depth here. NYBG has “boots on the ground” in six Areas of Botanical Concern (ABCs), which are regions where conservation action is urgent and NYBG is well positioned to have a major influence on conservation outcomes: North America, the Caribbean, Southeast Asia, Pacific islands, the Atlantic Coastal Forest of Brazil, and Amazonia.

Photo of the cover of Biodiversity and Climate ChangeThe convergence of two global environmental challenges—the growing number of endangered plant and animal species and the increasing impact of climate change—is the subject of an essential book that is being published on January 8, Biodiversity and Climate Change: Transforming the Biosphere. Edited by NYBG Trustee & Gold Medal Winner Thomas E. Lovejoy and Lee Hannah, it is a timely, seminal compilation of 28 articles written by renowned experts on diverse aspects of the complex interactions between these urgent problems. The publication “serves as a comprehensive account of this greatest of threats to humanity’s future,” writes eminent biologist Edward O. Wilson, a Distinguished Counsellor to the NYBG Board, in the book’s foreword. “It will serve both as a textbook and a call to action.”

“A call to action” on climate change was a central theme of my recent post on Science Talk, but there’s much more to say about this subject. Among the many recommendations for action in Biodiversity and Climate Change are ones that botanical gardens are uniquely positioned to lead, in what could be termed a botanical approach to mitigating global warming. The approach involves using the natural power of plants to capture a major greenhouse gas, carbon dioxide, from the atmosphere through photosynthesis.

Climate Change Action, Post-Poland’s COP24

Posted in Environment on December 21, 2018 by Brian Boom

Brian M. Boom, Ph.D., is Vice President for Conservation Strategy; Director, NYBG Press and Science Outreach; and Bassett Maguire Curator of Botany at NYBG.


We at NYBG welcome the positive news out of the climate change talks (COP24) in Poland over the past weekend of the agreement reached by the international community—more than 190 countries—to a set of rules for implementing the landmark 2015 Paris Climate Agreement. 

Less welcome was the news that the conference’s final communique did not endorse the findings of the Special Report Global Warming of 1.5°C of the Intergovernmental Panel on Climate Change (IPCC), but rather only “noted” the publication. The report’s findings pertain to the impacts of global warming of 1.5°C above pre-industrial levels, and it concluded that we could reach the 1.5°C threshold as early as 2030. Yes, in 12 years! This unfortunate outcome reinforced the rapidly growing realization that non-governmental organizations (NGOs) must play a central role in averting dire climate change outcomes.

With their exotic flowers and lush foliage, orchids are often considered the quintessential tropical plant, but as a recent publication from NYBG Press demonstrates, they are also native to the northeastern United States. Orchids (or Orchidaceae, their scientific name) are among the 27 plant families that are now available in the third installment of treatments released as part of the New Manual of Vascular Plants of Northeastern United States and Adjacent Canada by Robert F. C. Naczi, Ph.D., NYBG’s Arthur J. Cronquist Curator of North American Botany, and Collaborators. The family treatments have been published as individual, downloadable PDFs that can be viewed on a variety of devices such as a desktop computer, tablet, or smartphone.

In the region covered by the New Manual, there are 84 species of orchids, according to the treatment by Matthew C. Pace, Ph.D., Assistant Curator of the William and Lynda Steere Herbarium at The New York Botanical Garden, and John V. Freudenstein, Ph.D., Professor of Evolution, Ecology, and Organismal Biology at The Ohio State University.

In Port-Vila and Luganville—Vanuatu’s two largest cities—most people live in buildings that are made in much the same way as those found in New York, Paris, or Sydney. But across most of Vanuatu, the great majority of people still live in small villages, and it is in these areas that we see the wisdom of traditional approaches to building houses. The advantages of these techniques—and the potential lessons for other areas that suffer increasingly from severe tropical weather—may be especially timely in light of Hurricane Florence, which has buffeted North and South Carolina with high winds and heavy rains.

Indian Pipes: The Parasitic Plants in Bloom at The New York Botanical Garden

Posted in Interesting Plant Stories on September 4, 2018 by Science Talk

Ashley Keesling is a graduate student at The Ohio State University who recently conducted a research visit to The New York Botanical Garden.

Intriguing and ethereal, Indian pipes (Monotropa uniflora) are often mistaken for fungi because of their pale, otherworldly appearance. Also known as ghost plants, they typically occur in well-established forests and are often thought of as indicators of healthy ecosystems—not the kind of plant you might think would grow in a dense urban area. However, pockets of preserved forests in New York City, such as the old-growth Thain Family Forest at The New York Botanical Garden, can allow species to flourish in unexpected places.

I came to the heart of the Bronx recently to hunt for Indian pipes in the Thain Forest as part of the research I am conducting for my master’s thesis at The Ohio State University.

These fascinating parasitic plants have been the subject of much interest over the years, including research by an early 20th Century NYBG scientist. Indian pipes are unusual in that they do not photosynthesize. Instead, they are mycoheterotrophic, meaning they obtain nutrients by parasitizing a type of fungi that associate with plant roots. These mycorrhizal fungi help the plants take up water and nutrients that might otherwise be inaccessible to the plants. In exchange, the plants provide the fungi with sugars created from the process of photosynthesis. Indian pipes take advantage of the relationship between another plant and its associated fungus and “steal” sugars from the fungus. This three-part symbiosis allows Indian pipes to ultimately get their nutrients from a photosynthetic plant through the means of a mycorrhizal fungi.

BronxAs part of The New York Botanical Garden’s ongoing project to document all of the plant life of New York City, the Botanical Garden’s Center for Conservation Strategy recently issued a new report, State of New York City’s Plants 2018, the first in what is envisioned as an annual overview of the status of the city’s spontaneous plant species—that is, native plants and non-native plants that have become established in the five boroughs.

The report, which was released at NYBG’s First Annual EcoFlora Conference, found that 2,029 plant species have been reported in New York City from 1807 to 2018. The most species-rich families are the grasses, daisies, and sedges.

At the other end of the spectrum are rare and endangered plants. The International Union for Conservation of Nature, which tracks threatened and endangered plant and animal species, ranks six New York City plant species as critically endangered worldwide, including four species of ash trees, the American chestnut tree, and Bayard’s Adder’s-Mouth orchid. Adding in New York City species that are considered rare, threatened, endangered or extinct by the U. S. government and New York State, some 13 percent of the city’s flora is imperiled or has gone extinct.

NYBG Scientist and Co-Author Receive the Society of Economic Botany’s 2018 Klinger Book Award

Posted in Book on July 3, 2018 by Science Talk

Messages from the GodsMessages from the Gods: A Guide to the Useful Plants of Belize, by NYBG’s Michael Balick, Ph.D., and Rosita Arvigo, D.N., is the winner of the 2018 Mary W. Klinger Book Award, which is given annually to an outstanding book in the fields of economic botany and ethnobotany.

The culmination of a research project that began in 1987, Messages from the Gods is both a cultural study and a specialized field guide, with information about native and introduced plants in Belize and their traditional and contemporary uses as sources of food, medicine, and fiber and in spiritual practices, among many other purposes. The Society of Economic Botany—the preeminent professional association of researchers who study the relationships among plants, people, and culture, which presents the annual Klinger award—recognized the book as a definitive resource with a breadth and depth of knowledge “that will serve as a primary source on the plants of Belize and their uses for many generations.”

“This book is a truly significant volume that culminates decades of close collaboration between the two authors and local experts in Belize who practice and teach plant-based medicine and crafts and who promote the conservation and appreciation of that country’s diverse array of plant species, ecosystems, and human communities,” said Gayle Fritz, Ph.D., the President of the Society for the last year.

Messages from the Gods was co-published by The New York Botanical Garden and Oxford University Press.
