More than half of the shrub-steppe and 70% of the grasslands have been converted to agriculture, from dryland wheat fields to vineyards. Frequent fires were part of the natural cycle of birth and rebirth, helping to curtail the spreading of shrubs and cedar. Understanding long-term environmental changes under natural and anthropic forces is helpful for facilitating sustainable development. Trip time: About 8 hours, depending on stops.
