Mapping the Green Continent: An Overview of the Flora of North America North of Mexico
For botanists, ecologists, and nature enthusiasts, understanding the vast diversity of plant life is a monumental task. One of the most ambitious scientific endeavors ever undertaken to address this challenge is the Flora of North America North of Mexico (FNA). This multivolume series serves as a definitive guide to the native and naturalized plants found across the northern reaches of the continent.
By providing a unified taxonomic framework, the FNA allows researchers to look beyond local borders and understand plant life on a continental scale. From the icy reaches of Greenland to the diverse landscapes of the United States and Canada, this project is documenting the very fabric of North American ecology.

What is the Flora of North America North of Mexico?
The FNA is a comprehensive scientific work designed to describe the plant life of North America north of the Mexican border. This includes the United States, Canada, Greenland, and the French overseas collectivity of St. Pierre and Miquelon. Unlike many regional guides, the FNA is intended to be the first work to treat all known flora in this entire geographic area.
Scope and Content
The project is incredibly broad in its biological scope. It covers both bryophytes (non-vascular plants such as mosses and liverworts) and vascular plants (plants with specialized tissues for conducting water and nutrients, such as trees, flowers, and ferns). To ensure scientific accuracy and usability, the series includes several key features:
- Taxonomic Descriptions: Detailed descriptions of all taxa (groups of organisms).
- Dichotomous Keys: Step-by-step identification tools that allow users to identify plants by choosing between two contrasting characteristics.
- Distribution Maps: Detailed mapping of the locations where all species and infraspecific taxa (sub-groups within a species) are found.
- Scientific Illustrations: Approximately 20% of the species are accompanied by custom line drawings created specifically for the series.

A Massive Collaborative Effort
A project of this magnitude cannot be achieved by a single individual. The FNA is a global collaboration involving approximately 1,000 contributors, including authors, artists, reviewers, and editors from around the world. This collective expertise ensures that the descriptions and classifications meet the highest scientific standards.
While the series was originally expected to conclude around 2017 with a total of 30 volumes, the project continues to evolve. As of 2024, 24 volumes have been published. To ensure accessibility for the modern scientific community, the contents of the volumes are made available online shortly after their publication.
Scientific Impact and Reception
The FNA has earned significant praise within the botanical community. Experts have noted that its comprehensive approach allows botanists to examine taxonomic traits (characteristics used to classify organisms) and geographical traits across the entire continent. This is a major advancement over older methods, where researchers were often limited to keys developed for a specific state or small region.
Reviewers, such as Paula Wolfe, have commended the series for its high standards and recommended it as an essential resource for the field.

Frequently Asked Questions
Which regions are covered by the FNA?
The series covers all of North America north of Mexico, specifically including the United States, Canada, Greenland, and St. Pierre and Miquelon.
What kind of plants are described in the series?
The work describes both bryophytes (such as mosses) and vascular plants (such as flowering plants and trees), including both native and naturalized species.
How can I identify plants using this series?
The series utilizes dichotomous keys, which are identification tools that guide the user through a series of choices to determine the identity of a plant.
Is the information available digitally?
Yes, soon after the publication of the physical volumes, the contents are made available online for easier access.
What makes the FNA different from regional plant guides?
Unlike regional guides that focus on a single state or area, the FNA provides a continental perspective, allowing botanists to study plant genera across the entire North American continent.
