For 2 years, the vegetation grew in a coloration space after which for some other yr in a nursery at round 9,800 toes (3,000 meters) to lend a hand them regulate to the altitude. Then, in 2021, they labored with the native indigenous neighborhood of Calimaya to plant the seedlings underneath “nurse vegetation,” which safe them from harsh prerequisites, at the northeast slope of the Nevado de Toluca volcano. They concerned about 4 other altitudes, starting from more or less 11,000 to 13,000 toes (3,400 to 4,000 meters).
