Yucca glauca: Great Plains Yucca Introduction Yucca glauca are commonly found all through the entire great plains. This type of plant covers a wide range of habitats from a dry sandy soil to a more humid clay type area. Yucca glauca are known as a mutalistic symbiotic plant that relies on the yucca moth, Tegeticula maculate, for its reproduction and overall survival. These plants need to be in an area where the water is well-drained with an adequate amount of full sun and generally on either prairie land or exposed hillside. They grow to about three feet tall with long thin light green leaves that have a sharp apex (point) at the end. Numerous drooping bell shaped flowers are found on a Yucca plant with each one holding a hardened capsule full of seeds; these are dispersed by the wind. Wind dispersal is not the only way for the Yucca to reproduce; they also have a unique rhizomatous root system that allows them to branch out along the underground called runners. This process allows the plant to start popping up almost anywhere. This study was conducted by the South Dakota/Wyoming border near Cox Lake, South Dakota. Site one, which was on the North side of the road, was conducted on a dry hillside slope that was clear of trees and faced the sun all day. This site has soil that was a mixture of red clay and sandy dirt which was thinner due to erosion as well as causing faster run off. Land here resembled a pasture that had been overgrazed and never a chance to recover. Site two at Cox Lake was more of a flat prairie grassland (Southside of road), which doesn't face all day full sun. The soil here was similar in composition with the hillside except the grasses were more plentiful on the flatland. Both site one and site two had areas that were clumped with Yucca while other areas had little to no Yucca. This brings me to my purpose of this paper, the hypothesis
