Joshua Tree - Mojave Desert
The Joshua tree is also called izote de desierto (Spanish, "desert dagger"). It was first formally described in the botanical literature as Yucca brevifolia by George Engelmann in 1871.
Joshua trees are fast growers for the desert; new seedlings may grow at an average rate of 7.6 cm per year in their first 10 years, then only about 3.8 cm per year. The trunk consists of thousands of small fibers and lacks annual growth rings, making determining the tree's age difficult. This tree has a top-heavy branch system, but also what has been described as a "deep and extensive" root system, with roots reaching down to 11 m. If it survives the rigors of the desert, it can live for hundreds of years; some specimens survive a thousand years. The tallest trees reach about 15 m . New plants can grow from seed, but in some populations, new stems grow from underground rhizomes that spread out around the parent tree.
The cache is up the tree. The only question is whether you can climb your way to the cache, or do you need a ladder. A situational assessment will be required.
Thank you to bggy for placing the cache container in the tree.
