“…First, the locality belongs to the Oaxaca state which has the highest orchid species richness in the country (Soto-Arenas & Salazar 2004, Solano-Gómez et al 2016, but from which only 20 % of its territory has been explored (García-Mendoza 2004). Second, most studies on orchid diversity have been conducted in rainforests and cloud forests (Mejía-Rosero & Pino-Benítez 2009, Focho et al 2010, Allesh et al 2011, García-González & Pérez-Márquez 2011, Gogoi et al 2012a, b, Morales 2012, Gutiérrez 2014, Damian 2015, Nurfadilah 2015, Susan-Tepetlan et al 2015, Castillo-Hernández & Flores-Olvera 2017, Tejeda-Sartorius & Tellez-Velasco 2017; thus, there is a lack of studies addressing the diversity of orchids at temperate forests such as the one found in Santa Catarina Lachatao. Third, the locality is found within the Sierra Norte of the Oaxaca state where the main economic activity is the forestry (Santiago 2018).…”

“…Although orchids are distributed in all ecosystems, most studies on the floristic diversity of this family of plants have been conducted in rainforests and cloud forests (Mejía-Rosero & Pino-Benítez 2009, Focho et al 2010, Allesh et al 2011, García-González & Pérez-Márquez 2011, Gogoi et al 2012a, b, Morales 2012, Gutiérrez 2014, Damian 2015, Nurfadilah 2015, Susan-Tepetlan et al 2015, Castillo-Hernández & Flores-Olvera 2017, Tejeda-Sartorius & Tellez-Velasco 2017. In contrast, fewer studies on floristic diversity of orchids have been conducted in temperate habitats (Cerros-Tlatilpa & Espejo-Serna 1998, Calatayud 2005, Luna-Rosales et al 2007, Huang et al 2008, Rewicz et al 2015.…”

Background: Orchidaceae represents around 7.1-8.52 % of the angiosperms known in the planet. In Mexico, orchids are the third family more diverse, and Oaxaca is the state with the highest richness in the country. Orchids are widely distributed in tropical environments, but they are also distributed in temperate forests, where they have been scarcely studied. Questions: What is the diversity of orchid species at the locality of Santa Catarina Lachatao? Which subfamilies and growth forms are distributed at that locality? Do the community of orchids flowers differentially between seasons? Studied species: Species of the Orchidaceae family. Study site and dates: Santa Catarina Lachatao, Oaxaca, 2017-2018. Methods: Orchids were collected monthly throughout a year. Collected specimens were identified. Richness, abundance and diversity index were estimated for the whole flowering community, and per subfamily and growth form. These parameters were compared between seasons. Results: The community of orchids was composed by 4,933 flowering individuals from 74 species from the subfamilies Epidendroideae and Orchidoideae. Orchids with terrestrial, epiphyte, and rupicolous growth forms were collected. Total diversity index and species composition varied between seasons. Seasonal variation in abundance, diversity and species composition per subfamily and per growth form was also detected. Conclusions: Orchid diversity at the locality is high (9.68 % of the richness recorded for Oaxaca), and varies between seasons. The high species richness, the endemisms and endangered species found, call to take prompt actions to protect and manage the forest to assure its conservation and the diversity within it.
