Field studies were undertaken to evaluate hoary cress (Cardaria draba (L.) Desv.) reproduction and spread in a sagebrush ecosystem. Hoary cress germination, emergence, and survival were restricted to moist environments. These conditions occurred 2 out of 8 years. Hoary cress germination under field conditions was greatest on toe slope positions and areas of soil disturbance. Number of shoots varied annually for established hoary cress populations. Shoot propagation was reduced when early spring growth was followed by frost or drought. Shoot numbers were increased when spring growth was delayed and warm, moist growing conditions occurred in May. Seed reproduction did not increase plant density in monitored populations. Established populations relied upon vegetative reproduction to sequester resources and increase plant density.
