    Due to a rapidly expanding human population in Florida, fire management has become hampered by urban encroachment, smoke management issues, and forest fragmentation. For these and other reasons, fire has been excluded from many stands, resulting in the buildup of dangerous fuel loads. These fuel loads have begun to result in recurrent destructive wildfires. Already, different communities are responding to these dangerous fuel loads in various ways.

    For some fifteen years, dairy cattle farming has been considerably developing in various parts of the Andes. Milk is transformed into cheese or sold fresh, giving rural families a regular income which secures their food supply.

    Selective grazing can modify the productive capacity of rangelands by reducing competitiveness of productive, palatable species and increasing the composition of more grazing-resistant species. A grazing system (season-long and short-duration rotational grazing) x stocking rate (light: 16 steers·80 ha-1, moderate: 4 steers·12 ha-1, and heavy: 4 steers·9 ha-1) study was initiated in 1982 on northern mixed-grass prairie. Here, we report on the final 16 years of this study (1991-2006). Spring (April+May+June) precipitation explained at least 54% of the variation in peak standing crop.
