In Defense of PlantsIn the effort to conserve the planet’s biodiversity, plants tend to be overlooked. People spend much more time and money on “charismatic” species of animals. For instance, 100 percent of the world’s known threatened and endangered animals have been assessed by the International Union for the Conservation of Nature, the most important global institution when it comes to evaluating such threats. But only assessed about five percent of plants have been assessed.

It’s a scary state of affairs, especially considering that so-called biodiversity hotspots are defined by their vascular flora.

The New York Botanical Garden is working to improve awareness and understanding about the botanical world. That was one of the topics when Matt Candeias of the blog and podcast “In Defense of Plants” interviewed Dr. Brian Boom who, among his other responsibilities at the Botanical Garden, is the Garden’s Vice President for Conservation Strategy.

In a new podcast from health insurer Cigna, Ina Vandebroek, Ph.D.—the Matthew Calbraith Perry Assistant Curator of Economic Botany and Caribbean Program Director at The New York Botanical Garden—discusses how she studies the ways in which Caribbean and Latino immigrants in New York use medicinal plants in their health care.

As part of her research, she delves into the traditional knowledge, beliefs, and practices of the Dominican and Jamaican communities and also carries out field research in the Dominican Republic and Jamaica.

Dr. Vandebroek talks about cultural beliefs about specific illnesses and herbal therapies that are recognized in these communities but unfamiliar in mainstream medicine, such as “evil eye.”

Putting her voluminous research to practical use, she has developed training activities with health care professionals to help them understand the traditional beliefs and health care practices of their Latino and Caribbean patients. Her aim is to give doctors and other providers the information and understanding they need to build trusting relationships with their immigrant patients—with fully informed, improved care as the ultimate goal.

You can listen to the 36-minute podcast here.

Dr. Vandebroek’s research is supported in part by a World of Difference grant from Cigna Foundation. 

From Tree to Shining Tree: The Living Network under the Forest

That old saying about not being able to see the forest for the trees turns out to be more than just a metaphor.  Standing in the middle of a forest, it’s easy to see each tree as an individual, but in reality, the trees are bound together by a living network that proves beneficial not only for the trees—which get the minerals they need to grow to great heights—but also to the network, which gets a steady supply of nutrients from the trees to keep it alive.

What is this network? That’s the mystery that award-winning science journalist Robert Krulwich sets out to answer in a recent episode of public radio’s Radiolab.

His scientific sleuthing brought him to the Thain Family Forest, the 50-acre old-growth forest at The New York Botanical Garden, where he interviewed Curator of Mycology Roy Halling, Ph.D., the Botanical Garden’s expert on all things fungal. That’s a pretty broad hint about the nature of the network, by the way.

As with all Radiolab stories, the result is an adventure in imaginative reporting and storytelling that revels in the wonders of the world around us. Or, in this case, beneath us.

You can hear the episode here.

The Science of Stink

Corpse FlowerAh, New York in the summer. So many fetid fragrances fill the air. The garbage on the sidewalk, the hot blast of exhaust from a passing bus, the dank odor of the subway—these and even less savory sources best left to the imagination all add their odors to the city’s atmosphere on a hot, humid day.

That makes it all the more remarkable that thousands of New Yorkers have flocked to The New York Botanical Garden to see the corpse flower that is now blooming in the Enid A. Haupt Conservatory. Apart from its size and striking appearance, the plant is notable for its stench, often compared to the smell of rotting flesh, which is the clever ploy it has evolved to attract pollinators.

Perhaps the fact that the plant blooms so infrequently and unpredictably draws most people, but many seem fascinated by the phenomenon that something in nature would smell this bad on purpose.

Watching some fireworks, going to the local parade, grilling burgers and hot dogs, maybe even finding time for a nap. Sounds like a classic Fourth of July. Collecting plant specimens is notably missing from this list. And yet, for botanists, our nation’s birthday is not necessarily a day off.

A search of the C. V. Starr Virtual Herbarium, where The New York Botanical Garden’s digitized herbarium specimens are made available online to researchers and the public, reveals that it includes no fewer than 6,808 specimens that were collected on a Fourth of July. They come from around the world, but more than 1,000 were snipped or dug up in the United States on Independence Day. They eventually found their way to the Botanical Garden’s William and Lynda Steere Herbarium, where they are now part of the 7.8 million specimens that are preserved there and are now being digitized for the Starr Virtual Herbarium.

The last scientific survey of the plants of Vietnam—written by two French botanists in 1937, when it was a French colony—led a team of researchers to expect that they would find about 60 species of palms when they began a research project in that Southeast Asian country in 2007.

To date, they have discovered 113 species, including 41 that are new to science, and an entirely new genus (a group of closely related species).

“Sometimes we can drive up a road and look out the window and see new species,” Andrew Henderson, Ph.D., Abess Curator of Palms at The New York Botanical Garden, told a group of Garden Members during a recent Britton Gallery Talk. “Vietnam was overlooked by biologists for a long time because of war.”

World Flora Online New York Botanical GardenAs if assembling a comprehensive, scientifically verified database of more than 350,000 plant species were not a daunting task to begin with, try doing it in only four years. That’s the ambitious goal the scientists working on World Flora Online (WFO) are racing to meet.

When it’s up and running, WFO will provide scientists, conservationists, political leaders, and other policy-makers with information they need to protect one of Earth’s most important resources—its plants.

More than two dozen of the world’s leading plant scientists gathered at The New York Botanical Garden recently to review the progress that has been made on WFO and to plan the way forward so they can meet the goal of completing the database in 2020, which was established in the Convention on Biological Diversity, an international agreement.

As part of a week-long series of meetings at the Botanical Garden, several of the participants spoke about specific aspects of this monumental project during a symposium on Wednesday, April 27, in the Garden’s Ross Hall.

The presentations began with introductory remarks by Barbara M. Thiers, Ph.D., the Garden’s Vice President for Science Administration and the Patricia K. Holmgren Director of the William and Lynda Steere Herbarium. She noted that the Garden is one of four leading botanical institutions that are working together to coordinate the efforts of scientists and institutions around the world to create this first-of-its-kind online resource.

Last fall, when the leaves were turning golden yellow and bright red in The New York Botanical Garden’s old-growth forest, two Botanical Garden scientists were on the other side of the world, trekking through a very different old-growth forest in northern Myanmar.

The scientists—Kate Armstrong, Ph.D., Myanmar Program Coordinator in the Institute of Systematic Botany, and Damon P. Little, Ph.D., Associate Curator of Bioinformatics in the Lewis B. and Dorothy Cullman Program for Molecular Systematics—are part of a major Garden research program to discover and document Myanmar’s botanical diversity, build the country’s capacity to carry out plant research, and promote the sustainable use of its forests.

Vanuatu, an island nation in the South Pacific Ocean, lies at the crossroads of regional groups of islands with a rich and original assortment of plant life, including species from Australia and Asia that were brought to these volcanic islands by wind, marine currents, and animals.

Comprehensive, accessible information about many of Vanuatu’s most noteworthy plant species is now available in one convenient volume, Remarkable Plants of Vanuatu, by Laurence Ramon and Chanel Sam, which is newly published by The New York Botanical Garden Press and Biotope, a French publisher. The text is in English and French.

Remarkable Plants of Vanuatu is intended to raise awareness of Vanuatu’s plant diversity among the general public and aid conservation efforts in the country, whose residents are largely rural and depend on plants for food, firewood, timber, medicine, and handmade goods.

Myanmar is a major biodiversity hotspot, yet its flora is probably the least studied in the Northern Hemisphere. As the country emerges from decades of isolation and political upheaval, The New York Botanical Garden is working to document Myanmar’s undiscovered plant life, build the country’s capacity to carry out plant research, and promote the sustainable use of its forests.

We recently returned from a collecting expedition to Hkakaborazi National Park in Kachin State, which borders China. The park, in the far northern part of the country, covers nearly 1,500 square miles of mountainous forest.

To reach it, we first flew to Yangon, Myanmar’s largest city. From there, we took a turboprop to Putao, the northernmost town in Kachin State, and then motorcycles to a small village. After that, we walked.
