MLRA notes

Major Land Resource Area (MLRA): 035X–Colorado Plateau

This ecological site is found in Common Resource Area 35.3 – the Colorado Plateau Sagebrush – Grasslands.

The Common Resource Area occurs within the Colorado Plateau Physiographic Province. It is characterized by a sequence of flat to gently dipping sedimentary rocks eroded into plateaus, valleys and deep canyons. Elevations range from 4800 to 6700 feet and precipitation averages 10 to 14 inches. The elevation range is lower (about 4500 to 6000 ) on the western side of the Colorado Plateau along the Grand Canyon, and moves up about 500 to 800 feet higher on the eastern side in the areas of the Navajo and Hopi Indian Reservations due to rain shadow effects from the Kaibab Plateau and Mogollon Rim. Common vegetation in this region includes Wyoming big sagebrush, Utah juniper, Colorado pinyon - cliffrose, Mormon tea, fourwing saltbush, blackbrush Indian ricegrass, needle and thread, western wheatgrass Galleta, black grama, blue grama, and sand dropseed. Sedimentary rock classes dominate the plateau with volcanic fields occurring for the most part near its margin. The soil temperature regime is mesic and the soil moisture regime is ustic aridic.

Physiographic features

This ecological site occurs on stabilized dunes with steep slopes. The overall slope of the site is 15 to 45 percent, but may include flatter or steeper spots. This ecological site is found on hillslopes, edges of plateaus and valley sides with soils that are deep to very deep to any plant root restricting layer. The surface texture of the soil is generally loamy sand, loamy fine sand or fine sand. Subsurface horizons are generally fine sand or sand.

Climatic features

Winter summer moisture ratios range from 70:30 to 60:40. Late spring is usually the driest period, and early fall moisture can be sporadic. Summer rains fall from June through September; moisture originates in the Gulf of Mexico and creates convective, usually brief, intense thunderstorms. Cool season moisture from October through May tends to be frontal; it originates in the Pacific and the Gulf of California and falls in widespread storms with longer duration and lower intensity. Precipitation generally comes as snow from December through February. Accumulations above 12 inches are not common but can occur. Snow usually lasts for 3-4 days, but can persist much longer. Summer daytime temperatures are commonly 95 - 100 F and on occasion exceed 105 F. Winter air temperatures can regularly go below 10 F and have been recorded below - 20 F.

Influencing water features

The soil moisture on this ecological site comes from precipitation. The site does not benefit significantly from run-on moisture. The sandy surface texture of the soil allows the site to capture the majority of both gentle winter storms and intense summer thunderstorms with little runoff.

Soil features

The soils associated with this ecological site are deep to very deep to any plant root restricting layer. The surface texture of the soil is generally fine sand, loamy sand to loamy fine sand. Subsurface horizons are generally sand, fine sand, loamy sand and loamy fine sand. Parent material is eolian material and alluvium derived mainly from sandstone. The soil ranges from slightly to moderately alkaline (pH 7.4 to 8.4). The permeability is moderately rapid to rapid and the soil profile can absorb all the moisture the climate can supply. The available water capacity is very low to low. Wind erosion is a severe problem if the vegetative cover is lost. Soil moisture regime is ustic aridic. Soil temperature regime is mesic.

Typical taxonomic units on this site include:
SSA 711 Navajo Mountain Area MU's 35 Pinavetes and 39 Mido;
SSA 713 Chinle Area MU 39 Mido;
SSA 715 Fort Defiance Area AZ/NM MU's 82 & 84 Pinavettes family.

Ecological dynamics

The plant communities found on an ecological site are naturally variable. Composition and production will vary with yearly conditions, location, aspect, and the natural variability of the soils. The historical climax plant community (HCPC) represents the natural potential of plant communities found on relict or relatively undisturbed sites. Other plant communities described here represent plant communities that are known to occur when the site is disturbed by factors such as grazing, fire, or drought.

Production data provided in this site description is standardized to air-dry weight at the end of the summer growing season. The plant communities described in this site description are based on near normal rainfall years.

NRCS uses a Similarity Index to compare existing plant communities to the plant communities described here. Similarity Index is determined by comparing the production and composition of a plant community to the production and composition of a plant community described in this site description. To determine Similarity Index, compare the production (air-dry weight) of each species to that shown in the plant community description. For each species, count no more than the maximum amount shown for the species, and for each group, count no more than the maximum shown for the group. Divide the resulting total by the total normal year production shown in the plant community description. If rainfall has been significantly above or below normal, use the total production shown for above or below normal years. If field data is not collected at the end of the summer growing season, then the field data must be corrected to the end of the year production before comparing it to the site description. The growth curve can be used as a guide for estimating production at the end of the summer growing season.

The State and Transition model shows the most common occurring plant communities likely to be encountered on this ecological site. This model may not show every possible plant community, but only those that are most prevalent and observed through field inventory. As more data is collected these plant communities may be revised, removed, and some added to reflect the ecological dynamics of this site.

Prescribed grazing, insect infestation (beetle kill) and/or extensive woodcutting, followed by periods of favorable or return normal precipitation events.

State 2
Native/ Introduced Annuals

This state has native shrubs and grasses, but now has introduced non-native annuals in the plant community. This is a loss of biotic integrity and degradation of soil site stability. Severe droughts, unmanaged grazing and frequent soils surface disturbance has allow for the introduction and establishment of non-natives. During periods of above average precipitation annuals can produce moderate amounts of cover.

Community 2.1
Native Grass/Shrub with Introduced Annuals

Introduced exotic annual grasses and forbs are present in minor amounts in the plant community, but the amount and proportions of native plants is similar to that found in plant community 1.1, Reference Plant Community.

Community 2.2
Shrubs with Grasses/Trees with Introduced Annuals

This plant community has a mix of large and half-shrubs with scattered overstory of trees. Grasses cover is reduced and most grasses are found within the shrub or tree canopies. Introduced exotic annual grasses and forbs are present in moderate amounts (5-25%) in the plant community.

State 3
Disturbed Surface

This state is dominated by trees and shrubs with native and non-native annuals. Grasses are mostly absent or severly reduced. Bare ground patches are large and connected within the woody canopy. There are active signs of erosion and deposition.

Community 3.1
Woody Overstory with Disturbed Surface

This site is characterized by a overstory canopy dominated by Junipers and Pinyon Pine with a understory of annuals and scattered shrubs and succulents. Prolonged drought conditions along with improper grazing have reduced the perennial herbaceous ground cover and increased soil erosion. There is significant disturbances to the soil surface through rills and gullies. Gullies show signs of active headcutting and rills/water flow patterns are evident and connected. A return pathway for this plant community may existm but is not displayed in the state and transition model. The possibe return pathways to state 2 may take several years or decades to occur thru management and practices, but may not be feasible due to the need for significant inputs.

Transition T1A
State 1 to 2

Introduction of non-native annuals species creates an irreversible change in the plant community

Transition T1B

Continuous heavy grazing and/or continous soil surface distance, natural tree regeneration/lack of fire, Introduction of non-native annuals, reduced perennial cover.

Transition T2A
State 2 to 3

Continuous heavy grazing and/or continous soil surface distance, natural tree regeneration/lack of fire, loss of perennial cover.

Restoration pathway R2A
State 3 to 2

Brush treatment to control woody species, reseeding or seed source for grass recovery, Prescribed grazing or No grazing. This pathway may not be feasible on a large scale due to significant inputs required.

Interpretations

Animal community

This site has limited suitability for grazing by stocker cattle, horses, and sheep during spring, summer and fall with a good variety of plants. In areas of steep slopes, livestock grazing is severely restricted and proper grazing distribution is often impossible to attain. Heavy use may occur in areas where access areas are frequented by livestock.

This site provides a great deal of habitat diversity because of the variety of food, topography, exposures and cover for wildlife species. Water can be scarce in natural springs or pockets.

Wildlife found on this site include golden eagles, red-tail hawks, badgers, porcupines, ground squirrels, snakes, blacktail jackrabbits, lizards and mule deer.

Recreational uses

Site is typically on edges of escarpments, terraces, valley sides and hills with sandstone parent material. It produces a mix of grasses, shrubs, forbs and a light overstory of trees which can be very picturesque.

Winters are cold, however, relatively mild spring, fall and summer months are attractive to recreationists.

Activities include hunting, cross-country riding, photography, hiking, and wildlife observation

Rangeland health reference sheet

Interpreting Indicators of Rangeland Health is a qualitative assessment protocol used to determine ecosystem condition based on benchmark characteristics described in the Reference Sheet. A suite of 17 (or more) indicators are typically considered in an assessment. The ecological site(s) representative of an assessment location must be known prior to applying the protocol and must be verified based on soils and climate. Current plant community cannot be used to identify the ecological site.

Composition (Indicators 10 and 12) based on	Annual Production

Indicators

Number and extent of rills:
A few rills may form on steepest slopes.
Presence of water flow patterns:
Somewhat common, probably cover no more than 15% of the area; mostly discontinuous, usually less than 8 feet in length. On steepest slopes water flow patterns may be continuous and as long as 12 feet in length.
Number and height of erosional pedestals or terracettes:
Pedestals and terracettes may be common, especially during a drought, due to high wind erosion hazard of the soils and steepness of soils.
Bare ground from Ecological Site Description or other studies (rock, litter, lichen, moss, plant canopy are not bare ground):
Bare ground averages about 50%. Drought may cause an increase in bare ground.
Number of gullies and erosion associated with gullies:
Uncommon, but occasional gullies will form in natural drainages on steeper slopes due to reduced plant cover and lack of rock fragments.
Extent of wind scoured, blowouts and/or depositional areas:
Some wind scoured areas and depositional areas may occur, especially on edges of escarpments and during droughts, due to high wind erosion hazard of the soil. High wind erosion hazard occurs on soils with surface textures of loamy sand, fine sand and sand.
Amount of litter movement (describe size and distance expected to travel):
Herbaceous and fine woody litter will be transported primarily by wind and in water flow pathways. Coarse woody litter will remain under tree and shrub canopies.
Soil surface (top few mm) resistance to erosion (stability values are averages - most sites will show a range of values):
Soil surface texture range from loamy sand to sand. Coarse rock fragments range from 0 to 15 percent and help protect the site. Soil on this site will often have a thin crust (biological or physical) providing some protection against erosion. Soil aggregate stability ratings should average 3 under plant canopies and 2 in the interspaces.
Soil surface structure and SOM content (include type of structure and A-horizon color and thickness):
Soil surface structure is single grain; loose, but some soil surfaces are weakly granular. Surface textures are loamy sand, loamy fine sand and fine sand with thickness ranging from 2-3 inches. Surface color is light brown (7.5YR 6/4) and subsurface is pink (7.5YR 7/4), however color can be variable with hues of 5YR to 7.5YR.
Effect of community phase composition (relative proportion of different functional groups) and spatial distribution on infiltration and runoff:
This site is characterized by scattered plants with a light overstory of trees, generally with less than 15% canopy cover by trees. The plant community consists of about 50% grasses, 35% shrubs, 10% trees and succulents with about 5% forbs. Basal cover range from 5-15% (Grasses>Shrubs>forbs>trees).
Presence and thickness of compaction layer (usually none; describe soil profile features which may be mistaken for compaction on this site):
None
Functional/Structural Groups (list in order of descending dominance by above-ground annual-production or live foliar cover using symbols: >>, >, = to indicate much greater than, greater than, and equal to):

Dominant:
Cool season bunch grasses > warm season grasses > shrubs

Sub-dominant:
forbs >= trees > Opuntia and other succulents

Other:

Additional:
Amount of plant mortality and decadence (include which functional groups are expected to show mortality or decadence):
All plant functional groups are adapted to survival in all but the most severe droughts. Sever winter droughts affect shrubs and trees the most. Severe summer droughts affect grasses the most.
Average percent litter cover (%) and depth ( in):
Litter is a mix of fine herbaceous litter and coarse woody litter. Litter cover and depth will be highest beneath shrubs and trees. Litter cover and depth is lowest in the plant interspaces.
Expected annual annual-production (this is TOTAL above-ground annual-production, not just forage annual-production):
Average annual production on this site is expected to be 500 to 600 lbs/ac in a year of average annual production.
Potential invasive (including noxious) species (native and non-native). List species which BOTH characterize degraded states and have the potential to become a dominant or co-dominant species on the ecological site if their future establishment and growth is not actively controlled by management interventions. Species that become dominant for only one to several years (e.g., short-term response to drought or wildfire) are not invasive plants. Note that unlike other indicators, we are describing what is NOT expected in the reference state for the ecological site:
Broom snakeweed, rabbitbrush, yucca, Mormon tea, dune broom, and sandhill muhly occur naturally on this site, but can increase with disturbance. Plants that have the potential to invade this site are cheatgrass, ripgut brome and Russian thistle. Both juniper and pinyon pine have the potential to increase and invade a site with overstory canopies reaching up to 30% in the absence of fires and favorable climatic conditions for tree regeneration.
Perennial plant reproductive capability:
All plants native to this site are adapted to the climate and are capable of producing seeds, stolons and rhizomes except during the most severe droughts.
