Dispersal is a process that occurs after the pollination of a flower; and bears fruit; animals usually eat those fruits and leave the seeds on the forest floor. Additionally, sometimes the seed passes through the intestinal tract, which makes the seed even more suitable for sewing. Wunderle Jr. (1997) writes, “In many plant communities, seed dispersal by animals is often an important form of propagule spread, and in some sites over half of the tree species have seeds dispersed by animals rather than by the wind, water or other forms". of dispersion. For example, in some neotropical forests, more than 66% of canopy tree species have seeds that are dispersed by animals" (p. 224). This is respectively what happens in pristine forests. They have a complete cycle: after reproduction and the formation of fruits, the seeds would be sown and the growth process would begin with germination. However, what happens in desert forests is that there are no animals
