韦弗和艾伯森（1956年第218页）描述环草有一个垫状生长，经常有死中心。这一模式与Strickland（1983年）报道的一些物种和Jansen（1988年）报道的利比亚半荒漠针叶草的模式相似。在南达科他州西部的半干旱地区，在植物密度低的地方，已经观察到蓝禾和小蓝茎草的环形图案或中空冠。以下是一些似乎可以解释南达科他州年轮生长模式的因素。这些因素可能也适用于其他领域。
Weaver and Aibertson (1956 p.218) describe ring grass as having a mat-like growth that frequently had dead centers. This pattern is similar to ones reported by Strickland (1983) for a number of species and by Jansen (1988) for semidesert needlegrasses in Libya. In semiarid areas of western South Dakota, ring patterns or hollow-crowns have been observed for blue grama and little bluestem where plant densities were low. The following are some factors which seemed to explain ring-growth patterns in South Dakota. Possibly, these factors are applicable to other areas.
