Wetlands and Prairies and Woods, OH MY!


The Government Land Office (GLO) conducted public land surveys of Iowa from 1832 to 1859. Deputy surveyors and their assistants produced both field notes and township maps that briefly described the land and its natural resources (vegetation, water, soil, landforms, and so on). These maps and survey notes are one of few data sources about vegetation distribution before much of Iowa changed to a landscape of intensive agriculture.
