Introduction

The Florida Gap Project is mandated by the National Gap Program, USGS/BRD to use the recently enacted United States National Vegetation Classification System (NVCS)as the classification for it’s vegetation map of the state of Florida (Anderson et al. 1998, Grossman et al. 1998; http://www.consci.tnc.org/library/pubs/class/). The NVCS is based on a hierarchical structure with vegetation physiognomic and floristic elements (Table 1).

The competing needs of producing a map with a high classification resolution and the use of landcover data from the LANDSAT satellite system has resulted in the development of a modified vegetation classification for the state based on the NVCS classification. Vegetation was classified to the Alliance level or to a higher aggregation of Alliances when discrimination to the Alliance level was not reliable.

Various factors can limit the type and content of a classification. For example, due to cloud cover and cost, the Florida Gap Project often used LANDSAT data from a single date for each scene. Adjacent scenes often were from seasonally different dates, resulting in spring/summer phenology for one scene and fall/winter phenology for another. Thus, reliable classification of deciduous versus evergreen dominated vegetation types was reduced.

The modifications consisted of two types. Classes were either generalized using elements of the mandated vegetation classification system, or Alliance and Formation levels of the classification were used. Generalized classes were called Compositional Groups and Ecological Complexes (Pearlstine et al. 1998). “Compositional groups are composed of alliances that are spatially discrete but cannot be discriminated into separate classes because of spectral similarity” and “Ecological complexes are distinguished from compositional groups in that it is the spatial closeness of the alliances that prevents discrimination based on satellite imagery” (Pearlstine et al. 1998).

Additional information necessary to understand this classification includes these Class level definitions (Grossman 1998).

Forest (I): Vegetation dominated by trees with their crowns overlapping, generally forming 60 - 100% cover; includes reproductive stages or immature secondary growth stands that are temporarily less than 5 meters or 16.5 feet tall.

Woodland (II): Open stands of trees with crowns not usually touching, generally forming 25-60% cover. Canopy tree cover (rarely) may be less than 25% in cases when the cover of each of the other lifeforms present (i.e. shrub, dwarf-shrub, herb, nonvascular) is less than 25% and tree cover exceeds the cover of the other lifeforms.

Shrubland (scrub) (III): Vegetation dominated by shrubs greater than 0.5 meters or 1.5 feet and typically less than 4 to 5 meters or 13 to 16 feet in height, forming greater than 25% cover, with trees forming less than 25% cover; shrub cover may be less than 25% in cases where the cover of each of the other life forms present is less than 25% and the shrub cover exceeds the cover of other life forms; does not include developing secondary associations dominated by tree species.

Dwarf-Shrubland (IV): Vegetation dominated by low-growing shrubs and/or trees, usually under 0.5 meters or 1.5 feet tall; dwarf-shrubs generally form greater than 25% cover, although (rarely) may be less, and tree and taller shrubs generally form less than 25% cover.

Herbaceous vegetation (V): Herbs (graminoids, forbs, and ferns) dominant, generally forming at least 25% cover. Trees, shrubs, and dwarf-shrubs generally with less than 25% cover. Herbaceous cover (rarely) may be less than 25% in cases when the cover of each of the other lifeforms present (i.e. tree, shrub, dwarf-shrub, nonvascular) is less than 25% and herbaceous cover exceeds the cover of the other lifeforms.

Nonvascular vegetation (VI): Nonvascular cover (bryophytes and lichens) dominant, generally forming at least 25% cover. Trees, shrubs, dwarf-shrubs, and herbs generally with less than 25% cover. Nonvascular cover (rarely) may be less than 25% in cases when the cover of each of the other lifeforms present (tree, shrub, dwarf-shrub, and herb) is less than 25% and nonvascular cover exceeds the cover of the other lifeforms. Crustose lichen-dominated areas should be placed in the Sparse Vegetation class.

Sparse vegetation (VII): Vegetation is scattered or nearly absent; total vegetation cover, excluding crustose lichens (which can sometimes have greater than 10% cover) is generally 1%-10%.

Due the difficulty of spectral differentiation of communities containing these species a broad more general class was created. The order of species in the class name does not represent the order of dominance. (Leitman et al. 1983, Loftin 1998).

The forest is dominated by Pinus elliottii var. densa and tends to be found on sand in the northern part of it’s range and limestone rock in the south part. This forest tends to have reduced canopy coverage compared to north Florida slash pine (Pinus elliottii var. elliottii)
    I.A.7.N.a. Tropical or subtropical needle-leaved evergreen forest
      I.A.7.N.a.020. Pinus elliottii Tropical Forest Alliance
14 Sand Pine Forest: Forest dominated by sand pine (Pinus clausa). No attempt was made to differentiate between Pinus clausa var. clausa and Pinus clausa var. immuginata. These forests are found on dry, sand ridges in the interior and along the coast.

15 Mesic-Xeric Mixed Pine/Oak/Hickory Forest Ecological Complex: This complex represents mesic to xeric mixed pine/oak/hickory forest. The dominant species may include varying levels of Pinus echinata, P. elliottii, P. palustris, P. taeda, Quercus falcata, Q. hemisphaerica, Q. virginiana, Carya glabra, and C. tomentosa. These species are not exclusive dominants for this class, but they were observed frequently during ground-truthing.
    I.C.3.N.a. Mixed needle-leaved evergreen - cold-deciduous forest
      I.C.3.N.a.049. Pinus echinata - Pinus taeda - Quercus (alba, falcata, stellata) Forest Alliance??

      I.C.3.N.a.180. Pinus taeda - Quercus (alba, falcata, stellata) Forest Alliance
16 Mesic-Hydric Pine Forest Compositional Group: This class represents multiple pine forest types. The variation found among forest types is dependent on slightly varying moisture conditions. The dominant pine type in the class tends to be slash pine (Pinus elliottii var. elliottii) flatwoods. Classes were combined because of the difficulty in differentiating pine types from satellite data.

      I.A.8.N.g.040. Pinus elliottii Saturated Temperate Forest Alliance
17 Swamp Forest Compositional Group: This class represents deciduous and evergreen swamp forests of north and central Florida. Classes were consolidated because LANDSAT satellite data from phenologically varying times (leaf on vs. leaf off) was not available. Leaf on or leaf off data were commonly available for adjacent scenes. The resulting classifications tended to consistently detect broad-leaved dominated swamp forest, but not differentiate deciduous from evergreen. This class may contain measurable, but not dominant amounts of cypress (Taxodium spp.). The class may contain some of the same species and species combinations as class 6 (Bay/Gum/Cypress Forest Ecological Complex). The Bay/Gum/Cypress forest was treated as a separate class because it is common to north Florida and was detectable using LANDSAT data and our classification techniques. Contrast with class 7 Loblolly Bay forest, in which this type of evergreen swamp was separable.

The difficulty of differentiating grassland and some forms of agriculture (e.g. hay) from pasture using spectral data has resulted in this lumped class. The class appears to be primarily pasture, although some overlap with sandhill and other open, graminoid type communities may have occurred.
67 Ag/Groves/Ornamental: This class represents orchards (e.g. pecan, peach, pear) and groves (e.g. Citrus).
68 Ag/Confined Feeding Operation/ Specialty Farms: This represents cattle feetlots and dairy farms.
