Description
Seasonal precipitation and temperature patterns play a significant role in Mediterranean grasslands, influencing within and between year variation in herbage production (Bentley and Talbot 1951, Rossiter 1966, Pitte and Heady 1978). Within the growing season, accumulated degree-days (AAD) which integrate season length with temperature should be an ideal index to herbage production in California's annual grasslands. This paper presents the simple correlations of seasonal herbage yield with ADD and proposes an efficient method of estimating seasonal herbage production profiles.
