The 14 largevolcano cones remain in their original state andpossess complete volcano craters. Vegetations onXiaogushan volcano cone and one or two othervolcano cones were once partially destroyedby human activity, but these actions havebeen completely stopped,and this vegetationsis undergoing restoration. The lava plateaus,whether the new period aa and pahoehoe lavaaround Laoheishan and Huoshaoshan volcanoes,or the massive lavas around the old periodvolcanoes, are all well preserved, and most ofthem are kept in original state. Human activities,such as some traces of construction, quarry miningand lumbering, and little patches of farm fieldswere found in some parts.

In the last 10 yearsefforts have been made to restore vegetationsdestroyed due to the basalt quarrying .
