In version 1, only polygons larger than one acre were retained in the published layer. In version 2, existing polygon boundaries were split, reduced in size, or merged, and additional polygons not captured in the original layer were digitized. If split, original IDs from version 1 were retained for one half and a new ID was created for the other half. In instances where adjacent meadows were merged together, only one ID was retained and the unused ID was “decommissioned”. If digitized, a new sequential ID was assigned. </SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="font-weight:bold;margin:0 0 14 0;"><SPAN><SPAN>Acknowledgements</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Tim Lindemann, Dave Weixelman, Carol Clark, Stacey Mikulovsky, Qiqi Jiang, Joel Grapentine, Kirk Evans - USDA Forest Service, Pacific Southwest Region </SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>Wes Kitlasten - U.S. Geological Survey </SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Sarah Yarnell, Ryan Peek, Nick Santos - UC Davis, Center for Watershed Sciences </SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>Anna Fryjoff-Hung - UC Merced </SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN /><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="font-style:italic;font-weight:bold;margin:0 0 0 0;"><SPAN><SPAN>Meadow Polygon Attributes </SPAN></SPAN></P><P STYLE="font-style:italic;font-weight:bold;margin:0 0 0 0;"><SPAN /><SPAN /></P><TABLE><TBODY><TR><TD><P STYLE="font-weight:bold;margin:0 0 11 0;"><SPAN><SPAN>Field</SPAN></SPAN></P></TD><TD><P STYLE="font-weight:bold;margin:0 0 11 0;"><SPAN><SPAN>Description</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>AREA_ACRE</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Meadow area in acres</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>STATE</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>State in which the meadow is located (CA or NV)</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>ID*</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Unique meadow identifier UCDSNMxxxxxx</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>*Note: IDs are non-sequential* </SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>HUC12</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Unique identifier for the Hydrologic Unit Code (HUC), level 12, in which the meadow is located</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>OWNERSHIP</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Land ownership status (multiple sources)</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>EDGE_COMPLEXITY</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Gives an indication of the meadow's exposure to external conditions EDGE COMPLEXITY = (MEADOWperimeter/EAC perimeter) [EAC = Equal Area Circle]</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>DOM_ROCKTYPE</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Dominant rock type on which the meadow is located </SPAN></SPAN><SPAN><SPAN>based on the USGS layer</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>VEG_MAJORITY</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Vegetation majority based on the LANDFIRE layer (GROUPVEG attribute)</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>SOIL_SURVEY</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Soil survey from which SOIL_COKEY, MAPUNIT_Kf, MAPUNIT_ClayTot_r, SOIL_MUKEY, and SOIL_COMP_NAME were assigned to each meadow (SSURGO or STATSGO depending on layer coverage)</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>SOIL_MUKEY</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Mapunit Key: Unique identifier for the Mapunit in which the meadow is located</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>SOIL_COKEY</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Component Key: Unique identifier for the major component of the mapunit in which the meadow is located </SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>SOIL_COMP_NAME</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Component Name: Name of the soil component with the highest representative value in the mapunit in which the meadow is located </SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>MAPUNIT_Kf</SPAN></SPAN></P></TD><TD><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>K factor: A soil erodibility factor that quantifies the susceptibility of soil particles to detachment by water.

As for the K and clay values for CA790 (Yosemite NP), because it is a new survey, O horizons were populated for those components. There may be a similar issue with the Tahoe Basin. NRCS does not populate the K factor for O horizons. And, at least at the time, NRCS is not populating any mineral material in the O horizons. Many NRCS national interpretations have been edited to look at the first mineral horizon and exclude the O.
