Researchers in North Dakota have correlated leaf-stage development with growing degree-days (GDDs) in several native and introduced grass species. Their findings allow range managers with large districts to supplement field observations with mean daily temperature data from local weather stations to determine when various spring "turnout" pastures will be ready for grazing in a given year. In this document this process has been modified for British Columbia.
