Introduction
Flowers2mexico002 is a national initiative coordinated by the Mexican Ministry of Science and Technology and the National Autonomous University of Mexico. It seeks to create a comprehensive, digitized catalog of the country’s floral biodiversity. The project was launched in 2018 as part of a broader effort to document Mexico’s rich plant diversity and to provide a reliable data foundation for conservation, research, and sustainable development. The program’s designation “002” indicates that it is the second phase of a multi‑stage effort; the first phase focused on preliminary surveys and database design, while the second phase expands coverage, integrates advanced geospatial analysis, and engages a wider network of stakeholders.
The initiative builds upon legacy collections held in Mexican herbaria, international databases, and historical literature. It incorporates field sampling across all of Mexico’s ecological zones, ranging from arid deserts to tropical rainforests, and it employs standardized protocols for specimen collection, identification, and data recording. By making the resulting data publicly available, Flowers2mexico002 aims to support scientific inquiry, inform policy decisions, and foster public awareness of the nation’s botanical heritage.
Flowers2mexico002 operates under the principles of open science, ensuring that metadata, georeferenced records, and associated images are freely accessible to researchers, educators, and the general public. The project also prioritizes capacity building, providing training in taxonomy, herbarium techniques, and biodiversity informatics to students and professionals across Mexico.
History and Background
Mexico has long been recognized as one of the world’s megadiverse countries, hosting more than 36,000 plant species, of which approximately 14,000 are endemic. Despite this wealth of biodiversity, a significant portion of Mexico’s flora remains undocumented, especially in remote and under‑studied regions. Early botanical explorations in the 19th and early 20th centuries produced extensive herbarium collections, yet these were often incomplete and lacked precise locality information.
In the early 2000s, international initiatives such as the Global Biodiversity Information Facility (GBIF) and the Global Plants Initiative highlighted the need for comprehensive, georeferenced plant data. Mexican institutions began to collaborate on national projects to digitize herbarium collections and standardize data formats. These efforts culminated in the establishment of the National Plant Biodiversity Program (PNB), which received initial funding from the national government and international donors.
The PNB launched its first phase in 2016, focusing on a pilot survey of 10 states and the digitization of 150,000 herbarium specimens. The successes of Phase I - including improved data quality, increased public engagement, and the creation of a national taxonomy database - provided the impetus for expanding the scope. Consequently, Phase II, branded Flowers2mexico002, was approved in 2018, with a budget allocation of US$12 million over five years, a network of 50 partner institutions, and an ambitious target of cataloging 95% of the country’s documented vascular plants.
Throughout its development, Flowers2mexico002 has maintained strong ties to international standards, notably the Darwin Core schema, to ensure interoperability with global biodiversity datasets. The project also aligns with Mexico’s National Biodiversity Strategy and Action Plan (SENASICA), reinforcing national commitments to conservation and sustainable use of biological resources.
Project Description
Flowers2mexico002 operates as a coordinated effort to assemble, verify, and disseminate plant data at a national scale. Its core components include field expeditions, specimen digitization, data quality control, and public outreach. The initiative is structured around a robust data management system that integrates geospatial information, taxonomic verification, and multimedia resources.
Goals and Objectives
- To provide a comprehensive, accurate, and georeferenced inventory of Mexican vascular plant species.
- To support taxonomic research by consolidating nomenclatural information and resolving synonymies.
- To enhance conservation planning through the identification of priority areas and species at risk.
- To facilitate the sustainable use of plant resources by creating a reliable reference for agronomy, pharmacology, and horticulture.
- To promote public engagement and education regarding Mexico’s floral heritage.
Scope and Coverage
The project covers all 32 Mexican states, including federal entities and the autonomous region of the Federal District. It encompasses a range of ecosystems: from the Baja California deserts and the Sierra Madre Occidental pine–oak forests to the Yucatán Peninsula mangroves and the cloud forests of Chiapas. The database currently contains over 300,000 records, with an annual addition of approximately 40,000 new entries.
Methodology
- Field Sampling: Teams of botanists and trained technicians conduct systematic surveys, collecting specimens following standardized protocols.
- Herbarium Processing: Specimens are pressed, dried, and mounted on sheets. Voucher numbers are assigned and recorded.
- Taxonomic Identification: Specimens are identified by experts using dichotomous keys, literature, and comparison with type material.
- Data Entry: Metadata - including collection date, locality, habitat, and collector - are entered into a centralized database using Darwin Core terms.
- Georeferencing: Accurate latitude and longitude coordinates are derived from GPS data or derived from descriptive locality information.
- Quality Assurance: Records undergo double‑checking, cross‑referencing with external databases, and validation by taxonomic specialists.
- Digital Dissemination: Final records are published on the project website and made available via GBIF and other open‑access platforms.
Data Collection and Management
Effective data collection underpins the success of Flowers2mexico002. The project adopts a tiered approach, combining high‑volume fieldwork with meticulous herbarium documentation and rigorous data management protocols.
Field Surveys
- Field expeditions are organized quarterly, targeting under‑represented bioregions identified through gap analyses.
- Teams consist of botanists, local guides, and research assistants, ensuring cultural sensitivity and community involvement.
- Collection permits are secured in accordance with Mexican law, and ethical guidelines are followed to minimize ecological disturbance.
- Specimens are stored in portable, climate‑controlled containers to preserve morphological features for accurate identification.
Herbarium Contributions
The project collaborates with 45 state herbaria, the National Herbarium of Mexico, and private collections. Existing specimens are scanned at high resolution (600 dpi), with accompanying metadata digitized. Historical collections dating back to the 18th century are integrated, providing a temporal dimension to the dataset.
Digitalization and Georeferencing
Geospatial data are processed using ArcGIS and QGIS. For each specimen, coordinates are assigned with an estimated error radius. In cases where precise GPS data are unavailable, locality descriptions are interpreted using gazetteers and historical maps. The resulting georeferenced dataset complies with the Minimum Information About a Georeferenced Record (MIAGR) standard.
Scientific and Conservation Impact
Flowers2mexico002 has catalyzed significant advances in botanical science and conservation planning. By providing a standardized, accessible dataset, the project supports taxonomic revision, phylogenetic studies, and ecological modeling.
