Dreshslera poae fungus overwinters on the lower portion of the grass plant in the crowns and roots. Survival in winter is by conidia and dormant mycelia in infected live plant tissue and saprophytically in dead tissue, such as thatch and mat. The pathogen has also been known to overwinter in the dead thatch layer under the turfgrass. [7]
Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in ...
Grass typically goes dormant during periods of cold or heat outside of its preferred temperature ranges; dormancy reduces the grasses' water demand. Most grasses typically recover quite well from a drought, but many property owners become concerned about the brown appearance and increase watering during the summer months.

Lightly degraded grassland is the least potent of the three and is characterized by patches of dead or no grass, spottily dispersed throughout the land. [5] Plant and animal diversity starts to lessen but becomes really apparent in moderately degraded grasslands, in which patches of dead grass increase in size and number.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

The shortgrass prairie is an ecosystem located in the Great Plains of North America.The two most dominant grasses in the shortgrass prairie are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides), the two less dominant grasses in the prairie are greasegrass (Tridens flavus) and sideoats grama (Bouteloua curtipendula).
