Section 62-340.000, F.A.C. - Definitions Flashcards
Aquatic Plants
Free floating plants such as duckweeds and water lettuce and underwater plants such as eel-grass and spatter dock
Canopy
the top layer of the forest; woody plants or palms with a main trunk at least 4” in diameter at DBH
Diameter at Breast Height (DBH)
4.5’ above the base of a tree; used as a reference point to measure trunk diameter
Facultative Plants (FAC)
plants which are so problematic in their distribution as to render them inappropriate for indicating inundation and/or soil saturation
Facultative Wet Plants (FACW)
plants which under natural conditions typically exhibit their maximum cover in areas subject to surface water inundation and/or soil saturation, but can also be found in uplands
Ground Cover
includes all plants which are less than 4.5’ tall or have a DBH of less than 1”; vines and lianas are not considered
Ground Truthing
on-site evaluations of the wetlands and their parameters necessary to accurately delineate a wetland
Inundation
pertains to all surface water at or above the soil surface
Obligate Plants (OBL)
those plant species which under natural conditions are only found or achieve their greatest abundance in an area which is subject to surface water inundation and/or soil saturation
Example(s): water lilies
Riverwash
includes areas generally considered to be alluvial
Saturation
the extent to which shallow water tables can create anaerobic conditions throughout the soil profile
Seasonal High Water
the elevation to which the ground and surface water can be expected to rise in a normal wet season
Subcanopy
generally thought of as the smaller trees and tall shrubs in the forest; plant must have a main stem more than 4.5’ tall and greater than 1” in diameter to be considered
USDA - SCS
the former United States Department of Agriculture - Soil Conservation Service, now known as the USDA - Natural Resource Conservation Service (USDA - NRCS)
