"A lot more of America is rural than wildland."

Rural is a larger identifier which encompasses wildlands. It also depends on what you classify as wildland. According to the dictionary it's uncultivated land. If we were to measure uncultivated and undeveloped rural land, how would that compare to the cultivated and developed rural land? If 17% of US land is cultivated and less than 10% is urban, do you really think that the majority of the US or even the majority of the rural area are not wildlands? Either way, it makes no difference to the argument. Some of the sources in your links even look at various crop lands. It just seems at this point you're grasping at irrelevant and unsupported straws.
