Peelbark St. John's-wort - Chapman's St. John's-wort / Longleaf Three-awn - (Yellow Pitcherplant, Parrot Pitcherplant) Shrubland


Element Identifiers

NVCS association: Hypericum fasciculatum - Hypericum chapmanii / Aristida palustris - Sarracenia (flava, psittacina) Shrubland

Database Code: CEGL008594

Formation: Seasonally flooded microphyllous shrubland

Alliance: HYPERICUM (CHAPMANII, FASCICULATUM) SEASONALLY FLOODED SHRUBLAND ALLIANCE (III.A.4.N.d.1)

Element Concept

Summary: This association, found in the western panhandle of Florida, includes shrublands dominated by Hypericum chapmanii, Hypericum fasciculatum, and Hypericum brachyphyllum. The dominant herbaceous species is Aristida palustris. Lobelia paludosa, Sarracenia flava, Sarracenia psittacina, and Rhynchospora macra are also abundant and characteristic. Sparse, short-statured stems of Taxodium ascendens may also be present.

Environment: This association occurs in seasonally flooded wetlands in an ecotone between herbaceous-dominated prairies/savannas and cypress stringers.

Vegetation: The vegetation is dominated by Hypericum chapmanii, Hypericum fasciculatum, and Hypericum brachyphyllum. The dominant herbaceous species is Aristida palustris. Lobelia paludosa, Sarracenia flava, Sarracenia psittacina, and Rhynchospora macra are also abundant and characteristic (NatureServe unpubl. data). Other species present include Aristida beyrichiana, Balduina uniflora, Chaptalia tomentosa, Coreopsis linifolia, Drosera capillaris, Drosera tracyi, Eriocaulon compressum, Fuirena breviseta, Lophiola aurea (= Lophiola americana), Oxypolis filiformis, Pinguicula planifolia, Pleea tenuifolia, Rhynchospora corniculata, and Xyris difformis.

Bald-cypress - Swamp Blackgum Basin Swamp


Element Identifiers

NVCS association: Taxodium distichum - Nyssa biflora - Acer rubrum - Magnolia virginiana Saturated Forest

Database Code: CEGL003804

Formation: Saturated cold-deciduous forest

Alliance: TAXODIUM DISTICHUM - NYSSA BIFLORA - (NYSSA AQUATICA) SATURATED FOREST ALLIANCE (I.B.2.N.g.9)

Element Concept

Summary: Stands of this forest are dominated by Taxodium distichum, Nyssa biflora, Acer rubrum, and Magnolia virginiana. It is known from Big Gum Swamp Wilderness, Osceola National Forest and may also occur directly to the north at Pinhook Swamp, Osceola National Forest and Okefenokee Swamp National Wildlife Refuge. It occurs in a large, poorly drained flat area, with some poorly defined creeks which are tributaries of the Middle Fork St. Mary's River. The site is along the flat divide between the Atlantic drainage (St. Mary's River) and Gulf drainage (Suwannee River).

Vegetation: This forest is dominated by Taxodium distichum, Nyssa biflora, Acer rubrum, and Magnolia virginiana. The subcanopy is composed of Acer rubrum, Magnolia virginiana, and Persea palustris. Shrubs are Lyonia lucida, Morella cerifera, Persea palustris, and Leucothoe racemosa. Toxicodendron radicans is an important vine, and Dulichium arundinaceum is the only sparse herb documented. In a stand from the Ocala National Forest, the canopy contains Nyssa biflora, Taxodium distichum, Acer rubrum, and Pinus elliottii. In addition, the subcanopy contains Ulmus americana (= var. floridana), Ilex cassine, Persea palustris, and Sabal palmetto. Shrubs include Diospyros virginiana, Fraxinus caroliniana, Ilex cassine, Itea virginica, Morella cerifera, Nyssa biflora, Persea palustris, Quercus nigra, Toxicodendron radicans, and Vaccinium virgatum. Vines include Parthenocissus quinquefolia, Smilax bona-nox, Decumaria barbara, and Vitis aestivalis. Herbs include Woodwardia virginica, Hypoxis curtissii, Peltandra virginica, Dichanthelium sp., Osmunda regalis, Carex sp., Chasmanthium nitidum, Mitchella repens, Osmunda cinnamomea, Solidago latissimifolia, and the epiphytic Tillandsia bartramii. This type is described from Big Gum Swamp Wilderness, Osceola National Forest, and a stand from the Ocala National Forest is also assigned here.

Dynamics: These forests are prone to flooding, especially after hurricanes.
