Diversidad florística y patrones paisajísticos en bofedales altoandinos de la reserva de producción de fauna Chimborazo-Ecuador
Contenido principal del artículo
Resumen
Este estudio evaluó la diversidad florística de bofedales altoandinos en la Reserva de Producción de Fauna Chimborazo (Ecuador) mediante el uso de índices de biodiversidad y análisis de teledetección (EVI y MNDWI). Se analizaron un total de 16 sitios de muestreo distribuidos en tres provincias andinas, identificándose 63 especies agrupadas en 25 familias. Las familias más representativas fueron Asteraceae y Poaceae, con especies dominantes como Distichia muscoides y Plantago rigida. Los índices de diversidad (Margalef: 2,07–3,38; Shannon: 2,17–2,83) indican una diversidad moderada típica de ecosistemas de alta montaña. El análisis espacial reveló que solo el 23% del área de estudio presenta cobertura vegetal, mientras que el resto carece de biomasa debido a condiciones geológicas. No se encontró una correlación significativa entre los índices espectrales y la diversidad florística. Estos resultados sugieren que los índices de teledetección, por sí solos, son insuficientes para caracterizar la complejidad ecológica de los bofedales andinos, destacando la necesidad de integrar variables ambientales adicionales.
