Conservation management codes were set depending not on individual PLS quarter-quarter sections, but on the administrating entity. This generalization may provide a code inaccurate for a particular parcel, but will provide a reasonably accurate assessment of the type of management practiced. Some ownership may have been omitted if the quarter-quarter section was primarily surface water. If the source database provided acreage less than half of the quarter-quarter section's area, but this comprised all of the land, it would not be coded into the base layer. Visual checks with known lake boundaries was done to correct this, but should not be regarded as a complete correction.
All polygons are closed and lines intersect where intended.
This includes county ownership without specific designation. State ownership from other sources is of varying completeness and vintage. Most federally owned lands are complete but smaller holdings are of older vintage, and may thus not reflect current ownership. Tribal ownership is complete for the state but does not include all federally owned lands held in trust or as reservation land. Privately managed lands are complete for over sixty counties.
