In recent years, interest in studying wetlands has been increasing but the impacts on these ecosystems have persisted with the subsequent deterioration of the ecosystem services they provide. One way of analyzing their diversity is through taxonomic diversity indices which provide valuable measures for their understanding and conservation. To evaluate the taxonomic diversity of the vascular flora using the Δ+ and Λ+ indices, as well as some of their diversity patterns related to the exchange of species in the coastal wetlands of Perú, we analyzed the existing data on 109 species of vascular plants distributed in eight coastal wetlands in this region. The Santa Rosa, Pantanos de Villa, and Carquín wetlands presented the highest Δ+ values suggesting the need for their conservation to protect the phylogenetic diversity in the harbor. Richness was correlated to the Δ+ (r = 0.931; p < 0.05) and Λ+ (r = -0.878; p < 0.05) indices and a reliable linear model of Δ+ was obtained as a function of richness (R2 = 0.86) whose use would simplify the calculation of taxonomic diversity of vascular plants in this region. No differences were found for Δ+ values between protected and unprotected wetlands (t = 0.96; p > 0.05) and no correlation between the distance from wetland to wetland and the beta diversity (p > 0.05). Additionally, our results suggest the importance of adopting measures to protect these wetlands establishing them as a coastal corridor including currently unprotected wetlands.
