Influencing water features

This is a wet site receiving water from runoff and seepage of adjacent sandy sites. It often has a perched water table at or near the surface for much of the year.

Wetland description

This site is considered hydric, but onsite delineations are needed to verify wetlands status.

Soil features

The soils of this site are very deep, poorly drained, rapidly permeable soils formed in sandy sediments. Because of the seepage from the adjoining slopes, water seeps to the surface for some time following rains. The soil is saturated or nearly saturated most of the year because of the seepage. Soil correlated to this site include: Cadelake, Melhomes, and Sealy.

Ecological dynamics

This site resembles a wet prairie or savannah occupied by a predominance of hydrophytic plants. The dominant herbaceous species include maidencane (Panicum hemitomon), velvet dichanthelium (Dichanthelium scoparium), plumegrass (Erianthus spp.), southern wildrice (Zizaniopsis miliacea), Vasey's grass (Paspalum urvillei), rice cutgrass (Leersia oryzoides), common rush (Juncus effusus), and bulrush (Scirpus spp.). Little bluestem (Schizachyrium scoparium), Indiangrass (Sorghastrum nutans), switchgrass (Panicum virgatum), broomsedge bluestem (Andropogon virginicus), and bushy bluestem (Andropogon glomeratus) occur on the higher slopes. Smartweed (Polygonum spp.), swamp sunflower (Helenium autumnale), and swamp rosemallow (Hibiscus moscheutos) are common forbs. Woody species such as black willow (Salix nigra), willow oak (Quercus phellos), water oak (Quercus nigra), eastern baccharis (Baccharis halimifolia), yaupon (Ilex vomitoria), and wax myrtle (Morella cerifera) may also occur on the site. The savannah structure of this site was probably influenced by the herding and grazing effects of bison and cattle. Wildfires occurring during extreme drought may also have played a role in the maintenance of the savannah landscape.

T2A	-	Abandonment, no fire, and/or no grazing management
R3A	-	Extensive brush management and/or herbicide applications

State 1
Savannhah

One community exists in the Savannah State, the Tallgrass/Wax Myrtle Community. The site is dominated by warm season perennial grasses and has a presence of 5 to 10 percent woody species intermixed.

Community 1.1
Tallgrass/Wax Myrtle Savannah

This reference plant community resembles a wet prairie or wet meadow and is dominated by warm season perennial grasses including maidencane, rice cutgrass, plumegrass, and common rush. Wax myrtle, possumhaw (Ilex decidua), and blackberry (Rubus spp.) are woody shrubs and vines that commonly occur throughout the site. Water oak, willow oak, and black willow provide a 5 to 10 percent canopy and occupy locations influenced by wetness. Water oak occurs on the higher/dryer upslopes while black willow occurs on the lower/wetter position of the site. Willow oak is intermediate between the two. Fire may play a part in the maintenance of the savannah landscape in years of prolonged drought. This site has the potential to produce heavy fine fuel loads but is usually too wet to have fine fuel moisture conditions conducive for burning. Since this site has such favorable moisture regimes, especially during the summer, grazing and browsing by bison, deer, and cattle probably had more influence on the maintenance of the savannah landscape. Due to the wetness of the site, mechanical brush management is rarely a treatment option for this site. The inability to selectively apply broadcast herbicide normally precludes this treatment option, although individual plant treatment with herbicides may be a viable option. Abandonment of the site allows a transitional shift in vegetation towards a shrub-dominated community that, over time, results in a tree/shrub state. The maintenance of the reference plant community seems to require the presence of grazing and browsing animals and periodic fire when conditions permit.

State 2
Shrubland

One community exists in the Shrubland State, the Wax Myrtle/Blackberry Shrubland Community. The state is defined by woody canopy cover from 20 to 40 percent. Herbaceous production is limited compared to the Savannah State (1).

Community 2.1
Wax Myrtle/Blackberry Shrubland

This is a transitional community moving from the Savannah State (1) to Woodland State (3). It occurs when the site is abandoned and no grazing, burning, or brush management is applied over time. Wax myrtle, blackberry, yaupon, and baccharis increase in density and canopy coverage (20 to 40 percent) and begin to hinder herbaceous production. Saplings of water oak, willow oak, black willow, and water elm (Planera aquatica) appear. The invasive Chinese tallow (Sapium sebiferum) will invade the site. If abandonment continues and no brush management or burning occurs, shrubs and vines continue to increase in density and canopy coverage is greater than 40 percent, which represents a transition to the Woodland State. Saplings begin to become trees and the resulting shading severely reduces the herbaceous production of the site where grazing and fire are no longer treatment options for recovery of the site.

Grass/Grasslike	600	900	1200
Tree	300	450	600
Total	3000	4650	6000

State 3
Woodland

One community exists in the Woodland State, the Cottonwood/Elm Community. The site is defined by woody canopy cover over 40 percent. The site has reduced herbaceous production compared to the Savannah and Shrubland States.

Community 3.1
Wax Myrtle/Oak Woodland

This is a steady state community that occurs following long periods, greater than 20 years, of little or no management (grazing, burning, or brush control). Water oak, willow oak, black willow, wax myrtle, and yaupon become the dominant plants in the community and severely limit herbaceous production through shading. The herbaceous community will be dominated by sedges (Carex spp.), rushes (Juncus spp.), and shade tolerant forbs. Available treatment options to move this community back to the Savannah State are limited to tree dozing during drought periods or individual plant treatments with herbicides. Neither of these treatments may be economically feasible.

Grass/Grasslike	480	640	800
Total	4800	6400	8000

Transition T1A
State 1 to 2

The driver for this transition is abandonment, lack of fire, and/or lack of prescribed grazing. Woody species are allowed to continue to grow until reaching over the threshold of 20 percent. This signifies the transition to the Shrubland State.

Restoration pathway R2A
State 2 to 1

Prescribed grazing, periodic fire, and brush management are practices that will restore the site back to the reference state. The key to successful restoration is controlling the growth of woody species throughout the site.

Transition T2A
State 2 to 3

The driver for the transition to the Woodland State is further abandonment, lack of fire, and lack of prescribed grazing. The woody species have grown to a canopy cover greater than 40 percent, which signifies this transition.

Restoration pathway R3A
State 3 to 1

The driver for restoration from the Woodland State to the Savannah State is management of woody species. Extensive brush management is required to open up the overstory canopy and allow for more herbaceous growth.

Interpretations

Animal community

The favorable moisture regimes of this site provide conditions that keep plants green and growing during dry summer months and periods of drought. The site is attractive to domestic livestock as well as many species of wildlife including white-tailed deer, bobcat, raccoon, raptors, rodents, song birds, and feral hogs. Animal species use may change as the plant community changes on this site. Livestock have a higher preference for the site in a Savannah State where white-tailed deer and feral hogs may prefer the site in a Shrubland or Woodland State. Management should be applied to the site to produce the habitat for the species of concern.

Hydrological functions

This site is a collection area for seep water coming from the sandy uplands that always surround it. Ponding may occur for periods throughout the year.

Recreational uses

This site may be used for wildlife viewing or hunting.

Wood products

In the Woodland State, willow oak and water oak could provide timber products for firewood, cross ties, hardwood flooring, and lumber. The wetness of the site in addition to the presence of the deep sandy upland soils that typically surround this site make logging and access to the site by log trucks difficult.

Other products

Fruit from blackberries and grapes may be harvested on this site.

Supporting information

Inventory data references

These site descriptions were developed as part a Provisional Ecological Site project using historic soil survey manuscripts, available site descriptions, and low intensity field traverse sampling. Future work to validate the information is needed. This will include field activities to collect low, medium, and high-intensity sampling, soil correlations, and analysis of that data. A final field review, peer review, quality control, and quality assurance review of the will be needed to produce the final document.

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.

Number of gullies and erosion associated with gullies:
Gullies are uncommon for this site.
Extent of wind scoured, blowouts and/or depositional areas:
None
Amount of litter movement (describe size and distance expected to travel):
Under normal rainfall, little litter movement should be expected.
Soil surface (top few mm) resistance to erosion (stability values are averages - most sites will show a range of values):
Soil surface is resistant to erosion.
Soil surface structure and SOM content (include type of structure and A-horizon color and thickness):
Soil surface structure is 0 to 15 inches thick with colors from dark grayish brown fine sandy loam to black loamy fine sand and subangular blocky structure. SOM is approximately 1 to 6 percent.
Effect of community phase composition (relative proportion of different functional groups) and spatial distribution on infiltration and runoff:
The savannah of trees, shrubs, vines, grasses, and forbs, along with adequate litter and little bare ground provides for maximum infiltration and little runoff under normal rainfall events.
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:
Warm-season tallgrasses > Cool-season midgrasses >>

Sub-dominant:

Other:
Trees > Shrubs/Vines > Forbs

Additional:
Amount of plant mortality and decadence (include which functional groups are expected to show mortality or decadence):
There should be little mortality or decadence for any functional groups.
Average percent litter cover (%) and depth ( in):
Small to large woody litter is common on this site.
Expected annual annual-production (this is TOTAL above-ground annual-production, not just forage annual-production):
6,000 pounds per acre for below average moisture years to 10,000 pounds per acre for above average moisture years.
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:
Potential invasive species include wax myrtle, blackberry, black willow, baccharis, willow oak, water oak, and Chinese tallow.
Perennial plant reproductive capability:
All perennial plants should be capable of reproducing, except for periods of prolonged drought conditions, heavy natural herbivory or intense wildfires.
