Seasonally flooded Coquinal: typifying a particular plant association in the northern Yucatan peninsula, Mexico

keywords: diversity, dry forest, endemic flora, flooded environments, Yucatan


Background: One of the most diverse and threatened plant associations in the Yucatan peninsula has not been characterized and therefore not included in any protection category in Mexico. We characterize and describe this plant association, which is rapidly disappearing or being irreversibly transformed as a result of anthropic activities. We propose a name and attempt a preliminary assessment of its taxonomic richness, and the identification of priority species to be preserved.

Questions: What is the species richness and plant endemism associated within this plant association? What are the ecologically important and high-priority species for conservation? How is it different from associated or similar plant associations?

Studied species: Vascular plants.

Study site and dates: Northern Yucatan peninsula; 2021-2023.

Methods: The plant association was characterized, and quantitative parameters were recorded. The Importance Value Index was estimated to assess its local ecological importance, and each species was assigned a conservation category in order to evaluate the conservation status in a global context.

Results: We propose Seasonally flooded Coquinal (SFC) as a name for this plant association based on geomorphological, physiognomic, and structural attributes. A total of 206 species were recorded, which two are endemic to the SFC and 28 to the Yucatan Peninsula Biotic Province (YPBP). Twelve species are listed under a risk category.

Conclusions: The SFC harbors a high plant diversity of endemic species to the YPBP, 12 of which are included in the IUCN red list, for which its typification and conservation should be a high priority in Mexico.
