Conservation gaps for the orchid Rhynchostele rossii: an integration of IUCN evaluation and ensemble species distribution models

Orchids, known for their beauty and intricate ecological roles, face significant threats from anthropogenic factors and climate change. This study focused on the conservation status and potential distribution of the understudied orchid species Rhynchostele rossii , native to Mexico and Central America. We observed a high predictive accuracy in determining the species distribution using an ensemble species distribution model. There has been a 37% reduction in habitat, primarily due to anthropogenic impacts. Conservation gaps are prominent, particularly outside established protected natural areas, underscoring the need for more comprehensive conservation measures. While regions like the Sierra Madre Oriental emerge as critical zones, the species find substantial protection in places like El Triunfo. The International Union for Conservation of Nature evaluation, combined with our findings, suggests classifying Rhynchostele rossii as "Near Threatened." The study highlights the importance of comprehensive conservation strategies to ensure the species' long-term sustainability, encompassing protected and non-protected regions. Furthermore, the potential medicinal properties of the species highlight the importance of conservation efforts.
