Target ecosystem state
Select a state
State 1
Non-Forested Wetlands







Description
These communities are characterized by a dense understory of hydrophytic grasses and herbaceous species with the absence of overstory trees and shrubs.
Submodel
State 2
Forested Wetlands






Description
This state is characterized by a dense overstory dominated by hydrophytic trees and shrubs. The understory often consists of sparse herbaceous and grassy species during the dry season. In the wet season the understory will hold standing water and support both aquatic floating and submerged species. Arboreal epiphytes will be very abundant on overstory trunks and limbs. These areas can be identified as forested wetlands by specific physiological adaptations to roots (pneumatophores or "knees") and trunks (buttressing). Mosses and lichens growing on the bark of these species will serve as an indicator to seasonal ponding levels by growing to the water line.
Submodel
Description
Rangelands are described as lands on which the indigenous vegetation is predominately grasses, grass-like plants, forbs, and possibly shrubs or dispersed trees. Existing plant communities can include both native and introduced plants. Primary export from Florida ranges are cattle and have been present in the state since their first introduction by Spanish explorers in 1521. Native forage production is very good with proper management in this community, with only a slight effect on the community. Proper management will often result in an increase of grasses and reduction of shrubs while also maintaining proper fire intervals. Rangelands provide a diversity of ecosystems and also provide a diverse and significant production of economic benefits and ecosystem goods and services. Livestock production along with sustainable wildlife populations provide for the major direct economic benefits, but also tourism, recreational uses, minerals/energy production, renewable energy, and other natural resource uses can be very significant. Vital ecosystem contributions include clean water, clean air, fish/wildlife habitat, as well as intangible considerations such as historical, cultural, aesthetic and spiritual values. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations or prescribed grazing practices.
Rangeland in this ecological site is described for the Non-Forested Wetland state, not for the Forested Wetland state. Non-Forested Wetland communities have higher percentages of forgeable species due to the natural community composition and structure and have commonly been used as rangeland since European settlement. Forested Wetlands may have some forgeable species in the understory but are not utilized primarily as rangeland. The major limitation to grazing species in these communities are extended hydroperiods represented by ponding conditions.
Submodel
Description
Pasture is a land use type having vegetation cover comprised primarily of introduced or enhanced native forage species that is used for livestock grazing. Pasture vegetation can consist of grasses, legumes, other forbs, shrubs or a mixture. The majority of these forages are introduced, having originally come from areas in other states or continents. Most are now naturalized and are vital components of pasture based grazing systems. Pasture lands provide many benefits other than forage for livestock. Wildlife use pasture as shelter and for food sources. Well managed pasture captures rainwater that is slowly infiltrated into the soil which helps recharge groundwater. Many small pasture livestock operations are near urban areas providing vistas for everyone to enjoy. It is especially important as livestock managers continues to experience extraordinarily high fuel and other input costs. Overgrazed pastures can lead to soil compaction and numerous bare spots, which may then become focal points of accelerated erosion and colonization sites of undesirable plants or weeds. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations or prescribed grazing practices. This grassland / pastureland state correlates with the 2013 Florida Forage Suitability Group G155XB245FL (Sandy Over Loamy Soils on Stream Terraces, Flood Plains, or in Depressions). If the reference communities are drained and then converted to grasslands or pasture, then forage species and values correlating with the 2013 Forage Suitability Group G155XY241FL (Sandy Over Loamy Soils, on Flats on Mesic or Hydric Lowlands) should be utilized.

Description
The agriculture industry includes cultivated crops, aquaculture, and apiculture. Cultivated cropland includes areas used for the production of adapted crops for harvest. These areas comprises land in row crops or close-grown crops that are in a rotation with row or close-grown crops. Primary exports from Florida consist of fruits, greenhouse and nursery products, sugar cane, and the signature export of citrus. Aquaculture includes the cultivation and maintenance of aquatic plants, aquatic reptiles, crustaceans, food/ ornamental fish, shellfish, and other miscellaneous species for harvesting. Apiculture includes the maintenance of honeybees and hives to provide beeswax, honey/ other edible bee products, crop pollination services, and sales of bees to other beekeepers. These areas have been modified resulting in land clearing practices and hydrologic management to fit the growers needs. It is strongly advised that consultation with State Agronomist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations.
Characteristics and indicators
Major natural resource concerns facing cropland include: (1) erosion by wind and water, (2) maintaining and enhancing soil quality, (3) water quality from nutrient and pesticides runoff and leaching, and (4) managing the quantity of water available for irrigation. For more specific information regarding cropland please contact your local NRCS office.

5.2. Non-Citrus Fruits
Description
This state is important and used by silviculturists, landowners, land managers, and the public/private industry. Silviculture is land used in controlling the establishment, growth, composition, health, and quality of forests and woodlands to meet the diverse needs and values of landowners and society such as wildlife habitat, timber, water resources, restoration, and recreation on a sustainable basis. These are forestry practices that include thinning, harvesting, planting, pruning, prescribed burning and site preparation, for managed goals such as wildlife habitat creation or harvesting.
Because of the generally wet soil conditions associated with forested wetlands, some of these areas can be very sensitive to forestry activities, particularly during ponded or periods of soil saturation. For silviculture operations in general, wetlands are probably most susceptible to changes in hydroperiod, which can result from improper forest road construction, logging operations, and certain types of site preparation activities. Due to management concerns within these wetlands, the creation and planting of tree plantations is not recommended and should be managed for stand harvesting and regeneration All silviculture operations should follow state and federal best management practices (BMP) to mitigate extensive damage to harvested wetlands.
These may include not significantly altering the natural drainage or flow patterns on forested lands, not conducting intensive mechanical site preparations such as bedding and fire line placement and avoiding road construction which may alter natural hydroperiods. For harvesting in these wetlands, specific criteria is used to prevent excessive damage to the natural system. These may include retaining leave trees for wildlife habitat and seeding, removing logging slash from the wetland system, minimizing heavy equipment operations which may cause extensive rutting, and only operating and harvesting in dry seasons/ periods or using specialized equipment in wetter conditions. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations for silviculture practices.
Resilience management
This state is managed by silviculture prescriptions that will vary based on individual forest stand and management goals.
Submodel
Description
This state represents the dominance of one or multiple non-native or exotic species which outcompetes the native natural community and may significantly alter the composition and structure of the invaded stand by overshading the canopy and understory components and preventing regeneration of forest species.
Submodel
Description
The reclaimed/ restored wetland state consists of non-forested and forested wetland communities which have undergone or currently undergoing transition from an altered state (agriculture field, pasture, mining land, urban areas) to a restored natural community. These reclaimed and restored natural communities will be managed to reflect the natural vegetation, management regimes, and hydroperiod of the reference community, with a history of land modification. This can often be accomplished through programs offered by the NRCS such as the Wetland Reserve Easements (WRE), a voluntary program to help restore and enhance wetlands which have been previously degraded due to agricultural uses. Restored wetlands will provide habitat to fish and wildlife, improve water quality by filtering sediments and chemicals, reduce flooding, recharge groundwater, protect biological diversity, and provide resilience to climate change. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations for silviculture practices.
Submodel
Description
These areas include soils that were intentionally and substantially modified by humans for an intended purpose, commonly for terraced agriculture, building support, mining, transportation, and commerce. The alteration is of sufficient magnitude to result in the introduction of a new parent material (human-transported material) or a profound change in the previously existing parent material (human-altered material). They do not include soils modified through standard agricultural practices or farmed soils with unintended wind and water erosion. When a soil is on or above an anthropogenic landform or microfeature, it can be definitely be associated with human activity and is assigned to a unique taxon, usually found as an "Urban land complex" within that communities' natural soil properties (e.g, Floridana mucky fine sand, ponded - Urban land complex, 0-1% slope).
Characteristics and indicators
Evidence of these areas include soils with manufactured items (e.g. artifacts) present in the profile, human altered-materials (e.g., deeply excavated or plowed soil) or human-transported material (e.g., fill), and position on or above anthropogenic landforms (e.g., flood-control levees) and microfeatures (e.g., drainage ditches). Detailed criteria regarding the identification of anthropogenic (artificial) landforms, human-altered materials, and human-transported material are in the "Keys to Soil Taxonomy" (Soil Survey Staff, 2014).
Submodel
Mechanism
This transition is driven by an absence of fire from a shrub – scrub wetland allowing for the establishment and dominance of existing woody species to mature into the canopy. This may be seen as a mixed stand of hardwoods and cypress species in an even aged stand or a pure overstory of cypress with a shrubby understory. Trees will often be greater than 20 feet (6 meters) in height.
Mechanism
This mechanism is driven by the introduction of livestock species to the natural system and implementing a planned grazing strategy. Use of a planned grazing strategy to balance animal forage demand with available forage resources. Timing, duration, and frequency of grazing are controlled, and some type of grazing rotation is applied to allow for plant recovery following grazing. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations or prescribed grazing practices.
Mechanism
Actions required to convert native habitat to pasture or forage production include herbicide application, seedbed preparation, and the establishment of desired plants. Decisions to convert native land to pastureland on this site should be made carefully and continuously evaluated before, during, and after conversion activities. This site is extremely susceptible to soil compaction and erosion. The decision to proceed with this action may have occurred before the regulation of wetlands within the state of Florida. Conversion may still be allowed if the proper permits are gathered in accordance with local, state, and federal regulations.

Mechanism
This transition represents proliferation and dominance of an invasive species. Soil mechanical disturbances can compound this effect and create suitable conditions for invasive species.
Mechanism
This transition is driven by the alteration and/ or transportation of soil materials via anthropogenic means.
Mechanism
This transition is driven by severe fire, usually occurring in periods of drought, or from anthropogenic decrease in the natural hydroperiod. If the roots were protected from fire, many species will rapidly re-sprout and form a shrub –scrub wetland. If the root systems were destroyed, these areas may be colonized by marsh grasses. The specific community of non-forested wetland will be dependent on local hydroperiods and geomorphic position of the area affected. Areas subject to removal of tree species via logging practices may be recolonized by a shrub – scrub wetland if not replanted and managed for its reference forested wetland community.
