seminar series



The Research Department hosts a seminar series that feature speakers on a wide range of topics in evolutionary biology and ecology.


Seminars are open to all and held on select Fridays at 4:00 pm during the academic year.

Please check-in at the Kiosk and tell Admissions staff that you are here for the seminar. You will be admitted at no charge and directed to the venue. Out of respect for seminar speakers and to limit disruptions, guests of the Botany Seminar Series will not be admitted to the Garden after 4:10 pm.

Flora of Sequoia and Kings Canyon National Parks – A Botanist’s Love Story

Dana York fell in love with the unusual plants he found while exploring Kings River Canyon in the mid-1990s. This subsequently led to documenting the floristics of the watershed for a Master’s of Science project with CSU, Fresno. A five year thesis study ensued which included over 300 days in the field, 2,000 voucher collections, an untold amount of photographs, and sorting through 35,000 herbarium sheets to find species collected within the study area. All the data were entered into a database. The thesis, A Phytogeographic Analysis of the Kings River Basin, California, was completed in 1999. The next phase of the flora included writing the species descriptions, obtaining more floristic study references for the region, working on the illustrations, and writing keys. The culmination of over 20 years of work was the publication of an Illustrated Flora of Sequoia & Kings Canyon National Parks in 2018. York will discuss and highlight the discoveries, steps, and tools used to keep the love affair going through the years!

A New Flora for the Northeast: Challenges and Opportunities

New Manual of Vascular Plants of Northeastern United States and Adjacent Canada is a collaborative project by New York Botanical Garden. The chief goal of this project is to produce a one-stop, indispensable reference on spontaneous plants of the region that integrates new data on systematics, identification, conservation, and floristics. The New Manual advances the legacy of manuals by previous NYBG authors, the first in 1901 by Nathaniel Britton, and the most recent by Henry Gleason and Arthur Cronquist in 1991. Several daunting challenges confront us with this project, which we view as opportunities to advance understanding of the region’s plants and demonstrate the increasing importance of fundamental botanical information. One challenge is the perception by many that botany is of little relevance to today’s problems. We face this challenge by incorporating several innovations in the New Manual relative to previous manuals. A second challenge is mounting conservation concern for a substantial proportion of the region’s native plants. We meet this challenge by conducting original research that yields data for conservation action. A third challenge is the current poor taxonomic circumscription for a surprisingly large number of taxa. To meet this challenge, we are conducting systematics research on select problems whose resolution will be especially useful for the New Manual and botanical knowledge generally.
