    Seasonal Biomass Growth (TI-NDVI).

    No full text
    <p>Shows how the 39 community pastures' seasonal growth in biomass compares to the 37 non-community controls (t-test = 2.103, df = 18, <i>p</i> = 0.05). Variation year-to-year is due to rainfall. Error bars = one standard error.</p

    Ten-Year Seasonal Growth Curve Comparison (NDVI).

    No full text
    <p>Shows how the 10-year average growth of the 39 community pastures compares with the average from the 37 non-community matched control sites (t-test = 2.715, df = 18, <i>p</i> = 0.014). The community pastures had a longer growing season and higher peak NDVI and produced more biomass than the non-community control pastures. *Above 0.1 is when plants can be grazed <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030991#pone.0030991-Zhou1" target="_blank">[26]</a>.

    Lowland area, 10-year average seasonal NDVI.

    No full text
    <p>Shows the 10-year average NDVI by the day of the year, with higher NDVI equaling greater grass biomass, and earlier greening and later senesce showing a longer growing season. “Lowland controls” shows the average of the control sites.</p
