The Protected Undisturbed Lands layer stems from a project employing large scale analyses of land use history across South Dakota and Southwestern Minnesota. Understanding the quantity of undisturbed grasslands and woodlands in this region is useful for assessing and informing land use conversion rates, habitat quality, soil and water quality and impacts on watersheds, land conservation and protection priority areas, and individual land management practices, amongst other things. Furthermore, understanding the protection status, especially the quantity and location of protected undisturbed lands, is essential for developing future land protection and conservation strategies. Previous attempts at quantifying undisturbed or native lands are inadequate for one of two reasons. 1) They employ statistical assessment methods at a small scale, which may provide valid information at a landscape or regional level, but are not scaleable to individual tracts of land. 2) They are based on assessments of native ground that occur on individual sites using ground surveys and other such tools, which are highly accurate for the sites surveyed, but may not cover all sites in an area, especially if undisturbed land is highly degraded or fragmented, thus they are not effectively scaleable to a landscape or region. The Potentially Undisturbed Lands project seeks to address both of these deficiencies by employing a landscape-wide deductive analysis approach at a scale resolution adequate for mapping individual tracts of land that show no apparent signs of prior or current disturbance. This protected lands layer further seeks to quantify and identify undisturbed lands that fall under some sort of permanent protection. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Protected Undisturbed Lands layer contains polygon features representing undisturbed lands that have a permanent protection status. It is a subset of the Potentially Undisturbed Lands layer (mn_pudl), and is created by intersecting the undisturbed lands layer with an aggregate layer of lands that are known to be permanently protected. Undisturbed land polygons were mapped at a scale of 1:8000 or greater over the entire Prairie Coteau and Lac qui Parle landscapes in Southwestern Minnesota. The project extent is defined by the layer: mn_pudl_cntyextent. Each polygon is classified as either undisturbed grassland or undisturbed woodland according to a rigorous, repeatable, systematic protocol. Permanently protected lands include an aggregate of fee title and easement holdings by a variety of state, federal, and private non-profit agencies and organizations.</SPAN></P></DIV></DIV></DIV> |
