State 1
Moist Hammock

Moist hammocks are evergreen hardwood and/ or palm forests with a variable understory typically dominated by palms and ferns occurring on moist soils, with limestone bedrock often at or very near the surface. They are characterized by a closed canopy with a dominance of oak species and cabbage palms.

Characteristics and indicators. Moist hammocks are typically low in height, no greater than 80 ft, with a closed canopy and sparse to open understory. Epiphytes are vastly abundant growing on tree trunks and limbs. What species exist in the understory compose of hydrophytic grasses, sedges, and ferns.

Community 1.1
Moist Hammock

This reference community is dominated with a closed canopy of oaks and palms, with a variable understory depending on flooding frequency and depth. They are typically low in height with a vast amount of epiphytes growing on tree trunks and limbs, providing to a very diverse species assemblage.

Resilience management. Flooding is the main driver in this community. Species composition is mainly influenced by flooding patterns. Frequency and depth of inundation have a profound effect on oak canopy composition as well, supporting species that are more tolerant of saturation, such as a shift from live oak to laurel oak. Fire is not a dependent management factor, moist hammocks are tolerant of light ground surface fires but are often rare.

Community 1.2
Palm Dominated Moist Hammock

After intense fires due to drought or drainage, intense fires may kill the overstory oak species and may replace this community with cabbage palm trees. Oaks and palms are tolerant of light surface fires, with intense fires favoring the growth of cabbage palms while killing the oak species. This community is rare however due to the rarity of fires within the moist hammock system. This community is characterized as a dominance of cabbage palms in the overstory rather than a codominance with oak species as seen in a moist hammock.

Pathway 1.1A
Community 1.1 to 1.2

This transition is driven by fires that may destroy the oak community within a moist hammock, leaving an open canopy forest dominated by cabbage palms. Another possible transition can be through the selective logging of oak species which will allow for the cabbage palms to become dominant in the canopy.

Context dependence. Fire is rare in moist hammocks, but in periods of extreme drought or effects of drainage may leave moist hammocks vulnerable to intense fires. Oak species are tolerant of light surface fires to maintain community structure, but intense fires may kill their root system and the tree. Cabbage palms however are tolerant of intense fires and favor them for optimal growth.

Pathway 1.2A
Community 1.2 to 1.1

This transition is driven by the regeneration of oak in the understory. Growth into the overstory will shift the community structure from a cabbage palm dominated stand to an oak- palm dominated forest typical of the reference community.

State 2
Altered Hydroperiod: Wet Hammock

This state refers to the alteration of the long term hydroperiod within a moist hammock system. While moist hammocks are tolerant and dependent on flooding to maintain community composition, increases in the long term hydroperiod may shift species vegetation towards more hydrophytic compositions. While slight increases in hydroperiods are seen in moist hammocks, reflected in the presence of hydrophytic vegetation such as cypress, large increases in hydroperiods may change the community altogether.

Community 2.1
Oak / Palm dominated Cypress Swamp

This community may be present where there has been an increase in the long term hydroperiod within the moist hammock community. This may happen due to fragmentation of a habitat, allowing flooding for longer periods of the year. This change is characterized by longer periods of flooding as well as the major presence / replacement of hydrophytic species in the overstory such as cypress.

State 3
Altered Hydroperiod: Dry Hammock

This state refers to the alteration of the long term hydroperiod within a moist hammock system. While moist hammocks are tolerant and dependent on flooding to maintain community composition, decreases in the long term hydroperiod may shift species vegetation towards more mesic and xerophytic compositions. While slight decreases in hydroperiods are seen in moist hammocks, reflected in the presence of mesic and xerophytic vegetation such as pines and saw palmetto, large decreases in hydroperiods may change the community altogether.

Community 3.1
Mesic Hammock

This community is the result of decreases in the long term hydroperiod within a moist hammock. This may be due to the effect of fragmentation or drainage of the site for preparation of rangeland or agricultural lands adjacent. It is represented by a presence of mesic species in the understory such as saw palmettos and more xerophytic shrubs. Note this is an altered moist hammock and not a reference community of mesic hammock,.

State 4
Invasion of Non-Native / Exotic Species

This state consists of Florida Department of Agriculture and Consumer Services (FDACS) Non-Native Category 1 Species list . More information on these species list can be found: https://www.fdacs.gov/content/download/63140/file/Florida%E2%80%99s_Pest_Plants.pdf or by contacting the UF / IFAS Center for Aquatic and Invasive Plants (http://plants.ifas.ufl.edu/), the UF / IFAS Assessment of Non-native Plants in Florida's Natural Areas (https://assessment.ifas.ufl.edu/), or the FWC Invasive Plant Management Section (http://myfwc.com/wildlifehabitats/invasive-plants/). This community will not represent every possibility of invasive species but rather the most common in these areas.

Characteristics and indicators. Non-Native species include species that exist outside of Florida's natural range and are introduced to the state via people, weather events, or any other means.

Resilience management. This state can be found as a part of any other state and can completely replace the native habitat if not properly managed. Restoration to natural communities after exotic non-native invasion includes practices such as mechanical and chemical removal.

State 5
Managed Resource Areas

The following communities comprise the major land uses in the United States and the land uses receiving the majority of the conservation treatment that address soil, water, air, plant, and animal resources within the USDA.

Characteristics and indicators. These land uses consist of areas that are not completely naturalized (i.e. native habitat) but are not completely altered by anthropogenic means.

Community 5.1
Rangeland

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. This is the reference community for this state because it requires very little alterations to the landscape for grazing species. 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.

Resilience management. Grazing, by both domestic livestock and wildlife, is the most common ecological management process, with fire and weather extremes also being significant ecological factors. For information regarding specific cattle grazing techniques please contact your local NRCS office.

Community 5.2
Open Transitional Managed Communities

This is an area that is managed to maintain open land before shifting to another community. These communities are often used as transitional periods from one practice to another and could lead to an abandoned / fallow field.

Community 5.3
Improved Pasture

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. Pasture is the basis of any livestock operation that is truly sustainable. It is especially important as livestock grazers continues to experience extraordinarily high fuel and other input costs.

Resilience management. Pastures receive periodic renovation and cultural treatments such as tillage, fertilization, mowing, weed control, and may be irrigated. For more information regarding specific pasture management please contact your local NRCS office.

Community 5.4
Agriculture

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 export from Florida consists 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.

Resilience management. 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.

Community 5.5
Silviculture

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. Many managed silvicultural lands in Florida include tree plantations for growth of tropical ornamental species such as palms; and lumber, pulp, and paper species such as slash pine, longleaf pine, cypress, and eucalyptus. This community also include management practices of agroforestry, the intentional mixing of trees and shrubs into crop and/or animal production systems to create environmental, economic and social benefits. This is included in this community and not any other state because the primary management is for tree species. This may include practices such as riparian forest buffers, windbreaks, forest farming, silvopasture, and alley cropping.

Resilience management. Management of silvicultural lands require specific prescriptions based on the management goals for the stand, and may include thinning, harvesting, planting, pruning, prescribed burning and site preparation. For more information regarding specific management for silviculture practices please contact your local NRCS office.

Pathway 5.1A
Community 5.1 to 5.2

This pathway is driven by land clearing practices that consists of removing the existing vegetation from the habitat and altering the habitat to prepare for modified land use.

Pathway 5.2A
Community 5.2 to 5.1

This pathway is driven by the restoration of the native habitat for the use of rangeland. This includes restoration of both the hydrology and landscape in advance of replanting native species. This is a time-consuming process and often results in second-hand community structure. Once restored to a natural capacity the introduction of grazing species to the system creates a managed rangeland.

Pathway 5.2B
Community 5.2 to 5.3

This pathway is driven by preparing the land for pasteurization. This includes the planting of vegetation consisting of grasses, legumes, other forbs, shrubs or a mixture that will provide preferred forage for managed grazing species.

State 6
Human Altered and Human Transported Areas

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 formed 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 taxa, usually found as an "Urban land complex" within that communities' natural soil properties (e.g., Urban land, 0-2% slopes).

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 deeply 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).

Community 6.1
Reclaimed Areas

Reclaimed areas are areas that have been modified through anthropogenic means that are restored to a natural or second-hand natural community. Areas that can be reclaimed are any intensity urban areas, and may be required to be reclaimed after urban use (e.g., active mines must be reclaimed). These practices include the identification, removal, and stockpiling soil materials before altering the land, and revegetation and replacement of soil materials after altering the land. This also applies to nearby urban areas that have been adversely affected by the anthropogenic activities.

Community 6.2
Urban

This urban community consists of development for human use. Urban areas include a variety of land uses, e.g., inner city or urban core, industrial and residential areas, cemeteries, parks, and other open spaces; the overall function which may benefit the quality of human life. These often form an urban soil mosaic, where the natural landscape has been fragmented into parcels with distinctive disturbance and management regimes and, as a result, distinctive characteristic soil properties. Within this community there are three different levels of urbanization, based off population dynamics, residential density, and intensity of development. These are labeled as low-intensity, medium-intensity, and high-intensity urban areas, which can eventually be split apart into its own separate state. Low-intensity urban areas may consist of single dwelling homes with little impact on the surrounding community which still somewhat represents the natural community (e.g., represents natural landscape, hydrology, and vegetation) , other examples of this are urban parks, cemeteries, or campgrounds with little urban development. Medium-intensity urban areas consist of larger urban dwellings with some natural features, but have been modified to meet urban needs (e.g., towns). High-intensity urban areas are areas of heavily modified areas with complete alterations of the natural landscape, hydrology, and vegetation to support a very large population, which once constructed is permanently altered (e.g., metropolis areas/ active mines).

Community 6.3
Non-Reclaimed Lands

Non-reclaimed areas are areas that have been modified through anthropogenic means that are unable to be restored to a natural or second-hand natural community. Areas that cannot be reclaimed are areas under active mining status or mined areas before the Phosphate Land Reclamation Act in 1975, which leaves shut down operations alone. These areas also include fallow mines that have been flooded and are now permanent bodies of water

Community 6.4
Landfills

This is an anthropogenic site for the disposal of waste material. It includes manufactured layers (artificial, root limiting layer below the soil surface) that are representative of human altered and human transported sites. These layers are often alternative between natural fill material and geotextile liners, asphalt, concrete, rubber or plastic that are built up and can rise above the surrounding landscape by 30 meters or more often impeding water, gas, or roots from moving through the profile.

Pathway 6.1A
Community 6.1 to 6.2

This shift in communities is driven by clearing and developing the land for the desired community.

This transition is driven by a decrease in the long term hydroperiod from natural or anthropogenic means.

Transition T1C
State 1 to 4

The invasion of non-native or exotic species can be driven by a multitude of different environmental factors such as changes in natural hydroperiods or in fire regimes. Typically once a change in one of the two factors mentioned above occurs, non-native or exotic invasive species become established and begin to compete with native species for habitat and nutrients.

Constraints to recovery. Recovery from non-native or exotic invasive species may be difficult due to many adaptations which allow them to outcompete and survive in intolerable conditions. Localized knowledge for each species must be known for best management of it it without harming the natural habitat, and often different treatments must be applied over one given area.

Context dependence. Growth of non-native and exotic invasive species can be rapid following a change in a natural stressor such as fire frequency or natural hydroperiods which might have once kept the invasive species at bay.

State 4 to 1

Mechanical, biological, and chemical removal strategies include removing the non-native and exotic invasive species through various mechanisms. Localized knowledge for individual non-native or exotic invasive species is needed for specific management. Sometimes introduction of fire regimes may prevent or stop the growth of non-native or exotic invasive species, but many species are fire tolerant. Mechanical removal might include roller chopping, harvesting, or cutting and removal of invasive species. Chemical removal might include aerial dispersal from planes, or basal bark injection treatments.
