(Wines&Vines) - Some of the blackened hills of the North Bay are sporting a light covering of green as new grasses push from the soil following November rains. Yet many of the trees on those hills are dead brown, and large swaths of blackened hillside remain in Sonoma, Napa, Mendocino and Solano counties. More than two months after fires ignited across the North Coast, much work remains to be done in ensuring the areas affected by the fires won’t be further damaged by significant erosion.
