Seasonal growth curves for forage production in different regions under historical (1961–1990) and future (2070–2099, for A2 and B1 emissions scenarios) climate conditions.

<p>Growth curves represent the accumulated forage produced on a daily time-step, summarized at monthly intervals as the amount of total forage produced over the season by that date. Each line shows the mean production for all years within each 30-year period and for all cells within each county. Only cells containing rangelands were used (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057723#pone-0057723-g003" target="_blank">Figure 3</a>).
