BARRERA-ZUBIAGA, Ezra J. E.; GRANADOS-SANCHEZ, Diódoro; GRANADOS-VICTORINO, Ro L. y LUNA-CAVAZOS, Mario. Characterization of four pinyon pine forests in the state of Zacatecas, Mexico. Rev. Chapingo ser. cienc. for. ambient [online]. 2018, vol.24, n.3, pp.275-296. Epub 19-Feb-2021. ISSN 2007-4018. https://doi.org/10.5154/r.rchscfa.2017.03.018.
Introduction:
Communities dominated in the canopy by pinyon pines harbor species richness and have complex physiognomy because they form an ecotone between arid and temperate zones.
Objectives:
To describe the floristic attributes that distinguish four communities dominated by pinyon pines; define units based on floristic composition and structure; and determine the influence of edaphic factors.
Materials and methods:
The flora of four communities in the state of Zacatecas was recorded. The arboreal and shrub vegetation was analyzed quantitatively using the point-centered quarter technique. Semi-realistic physiognomic profiles were made for each site. The groups resulting from cluster analysis were ordered with edaphic factors through a canonical correspondence analysis.
Results and discussion:
Floristic richness was 244 species; each community contains between 60 and 80 species. Structurally, three physiognomic variants were recorded: forests dominated by Pinus cembroides Zucc.; association of P. cembroides - P. cembroides var. bicolor Little; and forest dominated by P. maximartinezii Rzed. The pH, electrical conductivity and soil texture have a great influence on the structure and plant composition of the communities. The P. cembroides - P. cembroides var. bicolor association and its accompanying species develop in nutrient-poor soils, while P. maximartinezii forests prefer shallow soils.
Conclusion:
The floristic similarity among communities was low. Each community must be managed differently, meeting the particular requirements of the species that develop there.
