<br /> Additional reconnaissance data collection using numerous ocular estimates and other inventory data;NRCS clipping data for USDA
<br /> program support;Field observations from experienced range trained personnel.Specific data information is contained in individual
<br /> landowner/user case files and other files located in county NRCS field offices.

<br /> Hierarchical Classification Relationships
<br /> MLRA 69 is in the Piedmont and Raton Sections of the Great Plains Province.The MLRA is further defined by Land Resource Units(LRUs)
<br /> A,B,and C.The modal concepts of each LRU can be defined by soil properties and annual precipitation zones(PZ).Other features such as
<br /> climate,geology,landforms and key vegetation further refine these concepts,and are described in the Ecological Site Description(ESD).
<br /> LRU A(10-12 inches PZ)is the central portion of MLRA 69,extent is 2.4 million acres.There is irrigated cropland in the Arkansas Valley.
<br /> Precipitation is too limited for dryland crops.Most of LRU A is rangeland,and includes the Comanche National Grassland(FS).This LRU is
<br /> found in portions of Bent,Crowley,Otero and Pueblo counties.Soil Moisture Regime is Ustic Aridic.The Mean Annual Air Temperature
<br /> (MART)is 51-54°F.
<br /> LRU B(12-14 inches PZ)is 4.7 million acres and includes portions of Baca,Bent,Crowley,El Paso,Fremont,Kiowa,Las Animas,Lincoln,
<br /> Prowers,and Pueblo counties.Most of the LRU is in rangeland.Land uses include irrigated and dry cropland,small acreage and urban
<br /> ownership.Land east of 1-25 remains largely agricultural.Canyonlands are in the southern half and include Pinon Canyon Maneuver Site
<br /> and the Picket Wire Canyon of the Comanche NG.Soil moisture regime is Ustic Aridic and the MAAT is 50-54°F.
<br /> The Salt Meadow,LRUs A&B,site was developed from an earlier version of the Salt Meadow ESD(2005,revised in 2007).This earlier
<br /> version of the Salt Meadow ESD(2005)was based on input from NRCS(formerly Soil Conservation Service)and historical information
<br /> obtained from the Salt Meadow range site descriptions(1975,revised1983).This ESD meets the Provisional requirements of the National
<br /> Ecological Site Handbook(NESH).This ESD will continue refinement towards an Approved status according to the NESH.

<br /> Data collection for this ecological site was done in conjunction with the progressive soil surveys within the Upper Arkansas Valley(MLRA 69)
<br /> of Colorado.It has been mapped and correlated with soils in the following soil surveys:Baca County,Bent County,Crowley County,El Paso
<br /> County Area,Fremont County Area,Huerfano County Area,Kiowa County,Las Animas County:Parts of Huerfano and Las Animas,Lincoln
<br /> County,Otero County,Prowers County and Pueblo Area:Parts of Pueblo and Custer Counties.
