The Santa Marta páramo occupies the highest reaches of the Sierra Nevada de Santa Marta, an isolated mountain massif rising from the Caribbean coast of northern Colombia, separate from the main Andes, and it forms the northernmost stretch of páramo in South America. Above the treeline near 3,300 meters and below the permanent snowline around 5,000 meters, the landscape is a cold, high-elevation mosaic of tussock grassland, low scrublands and shrubs, bogs, and marshes, grading into sparse cushion grasses near the peaks. Rainfall is concentrated in the wetter months from roughly May to September, and the massif's isolation has produced exceptional endemism, including the plant genera Raouliopsis and Castanedia. Of the 125 angiosperm species endemic to the Sierra Nevada, 61 are confined to the páramo itself, and the ecoregion serves as habitat for the flagship Santa Marta parakeet. Much of the original vegetation has been lost to agriculture, settlement, and mining, and the surviving páramo is protected within Sierra Nevada de Santa Marta National Park.

About the montane grasslands & shrublands biome

High-elevation grasslands, meadows, and shrublands above the treeline or in mountain basins, including alpine and páramo systems. Cool temperatures, intense sunlight, and specialized, often endemic flora characterize them.

Catalog plants suited to this ecoregion

Computed from each plant's stated USDA zone range against this ecoregion's CHELSA-derived current zone range, with the CHELSA mid-century warming delta applied for the projection. Plants whose stated range falls outside both the current and projected zone end up dropped; the rest land in one of the three buckets below.

Collections for this ecoregion

No curated collection's plants all fit this ecoregion's zone range. We surface a collection only when every member would grow here — partial fits get filtered out rather than mislead. As the catalog and the curated set both grow, this section will fill in.
