Salt Marshes - biotic points of view Maia McGuire, PhD Florida Sea Grant Extension Agent

Slide 2

What is a salt bog? "A people group of developed halophytic vegetation in zones then again immersed and depleted by tidal activity." "Far reaching between or supratidal ranges involved by established rising vascular macrophytes and an assortment of epiphytes and epifauna." Emerged : standing out of the water; Halophytic : salt-cherishing; Inundated : overflowed; macrophyte : plant that is sufficiently vast to see; epiphyte : plant developing on another living being yet not a parasite; epifauna : creature rendition of epiphyte

Slide 3

Where are salt swamps found? Along intertidal shore of estuaries Flat, shielded waters Extensive from Maine-Florida, along Gulf coast from Florida-Texas In FL, most bounteous north of the stop line (70% of state\'s salt bog)

Slide 4

The salt bog group Plants Marsh grasses Associated halophytic (salt-tolerant) plants Animals Permanent inhabitants Visitors

Slide 5

Salt bog grasses Spartina alterniflora Smooth line grass Juncus roemerianus Black needle surge Cladium mariscoides Swamp sawgrass Spartina patens Salt knoll rope grass

Slide 6

Associated plants Many are succulent Exceptions incorporate saltgrass Many are consumable (saltwort, glasswort, ocean purslane) Form transitional zone between salt bog and sea loft

Slide 7

Salt bog zonation Intertidal—Spartina, Juncus High bog (above mean high water)— Distichlis spicata, Batis maritima , Salicornia spp., Borrichia sp., Sueda linearis, Limonium carolinanum Upper edge of high bog—Iva frutescens, Baccharis halmifolia Marsh-mangrove move zone

Slide 8

Resident creatures Littorina irrorata Marsh periwinkle (snail) Crabs Fiddler crabs ( Uca spp.) Marsh crabs ( Sesarma spp.) Geukensia demissa Ribbed mussel

Slide 10

The greater part of economically imperative marine species depend on estuaries/salt bog at some phase of life Examples incorporate blue crab, shellfish, hard mollusks, shrimp, red drum, seatrout, sheepshead, bluefish, mullet

Slide 11

Importance of salt bogs Productivity Habitat Erosion control Filtration

Slide 12

Productivity Biological term—measure of carbon delivered per m² per unit time 3 kg (powder free dry weight)/m²/year Limiting elements incorporate supplements, light Salt bog plants give garbage to the estuarine sustenance web Few nibblers on sharp edges (< 10% of biomass) Large detrital biomass bolsters expansive nourishment web

Slide 13

Partial salt bog sustenance web Dolphins Humans Fish Birds Oysters Insects Mussels Shrimp Crabs Snails Marsh grass Zooplankton Bacteria, growths Detritus Phytoplankton

Slide 14

Habitat Nursery grounds Feeding grounds Microhabitats Aerial Benthic Aquatic Stressful environment Rapid changes in temperature, saltiness, water profundity, broke up oxygen Sedimentation
