# Daniel E. Atha

Daniel Atha (born 1962) is an American botanist. In his work as a botanist he has collected plants in all 50 states of the United States, as well as several additional countries. Atha's work was focused on three areas: "floristics—what plants grow in a particular region; taxonomy—how to tell one plant from another, what to call it and what it's related to; and applied botany—how plants are used for food, medicine, shelter and other useful purposes." Atha has been known as a prominent regional botanist, and the high-profile botanical projects with which he has been involved (such as the recent Spontaneous Flora of Central Park project) have garnered national and international attention.

## Career
### New York Botanical Garden

Daniel Atha was the Director of Conservation Outreach at New York Botanical Garden. Atha was involved in work related to invasive plants in the greater-New York City region, including Westchester County. While employed at the NYBG, Atha collected plant material for Merck, Pfizer, The National Cancer Institute, L’Oreal, Cornell Weill Medical Center and many other organizations. Atha was also the Associate Editor for Brittonia. Atha co-developed the curriculum for the course Pressing Plants for Art and Science, as part of the certificate program in Botany offered through the New York Botanical Garden’s Continuing Education Program. He has taught hundreds of students the techniques for collecting and preserving museum-quality herbarium specimens.
In 2021, Atha left the New York Botanical Garden due to their vaccination mandate, and also that same year, protested against a state bill that Jeffrey Dinowitz had co-sponsored to add COVID-19 to the required immunizations to attend school, wearing a yellow badge that Jews were ordered to wear during the Nazi regime. Dinowitz said the "display of swastikas and yellow Stars of David [...] were repugnant and offensive".
In 2022 he researched and wrote a report on the ecological history of Seneca Village for the Central Park Conservancy. Through 2024, he has continued to collect specimens for taxonomic and floristic studies, teach plant collecting techniques and research the genus Persicaria (Smartweeds) of North America.

#### New York City EcoFlora

This project, in the prototyping phase through 2017, was designed to engage New York city residents in protecting and preserving New York City's native plant species. The project aimed to use citizen scientists to gather and organize data related to plants, animals, fungi, and habitats in the region. This data will then be synthesized with existing historic natural history collections and scientific publications. "The New York City EcoFlora will be a real-time, online, ongoing checklist of plants—the first ever to connect plants in the web of life in New York City—that will result in a dynamic resource for conservation planning as well as in New Yorkers that are better informed about the importance of urban ecologies and who can contribute to protecting them."

#### Flora of Central Park

One of Atha's research projects involved documenting and collecting every naturally occurring plant in Central Park. This project represents a collaboration between The New York Botanical Garden, the Central Park Conservancy and the New York City Department of Parks and Recreation. The aims of this project are to document the wild flora of Central Park, and to provide an up-to-date botanical inventory "to aid on-going restoration, conservation, education and recreation programs and to document the flora for scientific, ecological and conservation studies."
The quote below comes from an interview Atha gave to The New York Times in 2015
   "We thought, 'Wow, Central Park is right in the middle of New York City, in the densest urban metropolitan region in North America,'" recalled Mr. Atha, who has studied plants in all 50 states, as well as Bolivia, Russia and Vietnam. "'And yet there is nobody documenting the flora today. How crazy is that?'"

#### Emerging Invasive: Corydalis incisa

Atha and others at the New York Botanical Garden and Lower Hudson PRISM (one of eight Partnerships for Regional Invasive Species Management in New York State) coordinated a team of citizen scientists to document and remove Corydalis incisa, an emerging invasive species found along the Bronx River in Westchester County, NY and Bronx County, NY.

## Art

Atha's parents were artists, and he has been involved in several community projects related to the intersection of botany and art.
