How do Joshua trees get their water?
Its widespread roots are about 3 feet deep. Water is stored in its trunk and leaves. The plant is pollinated mainly by the yucca moth and reproduction of the plant occurs when its black, flat seeds are scattered in the wind or when underground stems sprout near the parent tree. Joshua trees don't flower every spring.
What do Joshua trees need to survive?
Soil. Joshua trees can grow in sandy, loamy, rocky, and clay soils, but they must be well-drained and dry. Unlike many plants, the poorer the quality of soil, the better they are likely to grow. Fertile, rich soil is not the Joshua tree's friend.

Where do Joshua trees grow?
Today’s Joshua trees have a fairly restricted range, growing in an archipelago of isolated patches across the Mojave. During the lush Pleistocene, though, the trees grew across far more of the desert. At one point or another over that million-year period, Joshua trees grew near the Colorado River’s delta in present-day Mexico, 300 miles from the southernmost Joshua tree today. They grew in Death Valley at around 200 feet below sea level, perhaps lower. (Imagine sitting near a Joshua tree on the forested shore of Lake Manly, which filled Death Valley hundreds of feet deep.) And at one point or another during the Pleistocene, they likely grew almost everywhere between those two points.

How did the Mojave change?
Less rain and snow fell in the Southwest. The Mojave started getting warmer. The desert’s rivers went dry. The lakes they had fed became salt flats. Those Pleistocene animals that could not adapt to the new Mojave moved away or died out or both.
How do yucca moths work?
The females work for a few days, collecting and distributing pollen and laying eggs, and then expire . Within the developing Joshua tree fruit, five distinct seed chambers begin to develop. In one of those chambers, the yucca moth larva hatches from its egg and begins to eat. The seeds, little flat black flakes about the size of a lentil, grow to fill their chambers like stacked coins in a banker’s paper roll. The moth larva eats through one of the five stacks, chews its way out of the fruit and drops to the ground, then burrows into the soil to pupate.
Why do plants need seed dispersal?
If you’re a plant, seed dispersal is key to the survival of your species in the face of climate change . Some plants, like dandelions and tumbleweeds, rely on the wind to move their seeds from place to place. Others make their fruit attractive to birds, which eat them and then fly away, scattering pre-fertilized seeds widely across the landscape. For example, those Pleistocene piñons and junipers enjoyed help from seed-dispersing birds in escaping the warming desert floors; their populations migrated not only up the mountainsides but up to far north mountain ranges.
What is the most repulsive tree in the vegetable kingdom?

Why is the Joshua tree important to the ecosystem?
Because of the highly specific adaptations that allow the Joshua tree to survive in the Mojave Desert, it is often considered to be an indicator species for the health of that ecosystem. The key ecological relationship ensuring this plant’s survival is one of mutualism (a symbiotic interaction between two species that benefits both).

Joshua trees, like most other yucca species, rely exclusively on the female yucca moth (genus Tegeticula) for pollination, and no other animal is capable of performing this action.

How do Joshua trees survive in the desert?
Rigid leaves covered by a waxy surface help the Joshua tree survive in the desert by being able to resist wilting and water loss. Its widespread roots are about 3 feet deep. Water is stored in its trunk and leaves. The plant is pollinated mainly by the yucca moth and reproduction of the plant occurs when its black, flat seeds are scattered in the wind or when underground stems sprout near the parent tree. Joshua trees don’t flower every spring. This flowering is also tied to weather. Joshua trees produce few flowers after a warm winter, more after a cold one. A large Joshua will be about 30 feet tall, although there is one 58 feet tall in Lancaster that is estimated to be 1,000 years old.
Why do cacti grow spaced out?
The roots have tiny hairs that help them collect water. The plants often grow spaced out because of stiff water competition below the surface.
