Mangrove Conservation Jeopardy Thomas Becker, FFL Program Assistant Charlotte County Extension Service 10-20-15 What’s Missing in this picture Goal: Learn innumerable benefits of mangrove and proper maintenance Objectives • Demonstrate ‘How to’ apply a ppt./2010 jeopardy board template to a presentation • Adopt accepted norms relating to mangrove ecology, preservation, restoration and care • Understand the role and values of mangroves • Learn how to identify the differences between three mangrove species and those plants that often grow nearby Mangrove – red, black & white Constructed Canal Lot Forest, Eco- System, Fringe, Buffer, Back-bay Border, Swamps Wildlife Corridors, Tunnels, Remnants, Tree Islands, Aquatic Estuary Natural Mangrove along Gasparilla Island World Mangrove Distribution *National Geographic Magazine Charlotte Harbor Myakka River Peace River Pt Charlotte Lemon Bay Punta Gorda 18 Miles To Caloosahatchee Boca Grande Gulf River Cape Coral Captiva Ft Myers Sanibel Estero Bay What is an Estuary? Where fresh water meets salt water supporting GREAT plant and wildlife bio-diversity. Kidneys for the watershed improving water quality before going into the Gulf of Mexico. Charlotte Harbor estuary Shallow Water High biological diversity • Rivers • Barrier islands • Open water • Inlets • Salt marshes • Submerged • Oyster bars • Mud flats seagrass beds Species Living in SWFL Estuary Osprey Inshore lizardfish • 227 species of birds • 225 species of fish • 22 native species of • 468 native species of plants mammals including 84 non-natives Mangrove Forests in Florida (7 major estuaries w/mangrove) –Tampa Bay –Charlotte Harbor –Ten Thousand Islands & Rookery Bay –Florida Bay –Biscayne Bay –Lake Worth Lagoon –Indian River Lagoon 60,000 acres of submerged Charlotte lands Harbor Aquatic Preserve Mangrove Distribution in Charlotte Harbor* • 26% historic loss • 3% recent loss • 34% shoreline degraded Mangroves need thought of as part of the natural rather then constructed landscape *Charlotte Harbor National Estuary Program Draft 7 County Watershed Report Signs of a Healthy Estuary Mangroves line the shoreline with red, white and black mangrove Distinguishing between Fresh (water), Estuarine and Marine systems is often subtle Backyards are transition zones from the natural areas to yards. Plant Natives between home, yard, property border and mangrove Be In the Know – Protecting Mangrove • Three mangroves species grow along saline, tidally - influenced shores of the tropics/subtropics • Mangroves are preserved and protected as forested areas in Florida • Under FL law, only native plants can be planted along a shoreline • All mangroves species are cold-sensitive trees • Mangroves require NO watering • Of the three species, red mangrove does not survive severe pruning, nor the coldest temperatures for an extended period More Living on the Estuary (FFL™) • All mangroves protect water quality • Highest priority is preserving mangrove • Remove any prohibited exotics competing with existing mangrove • If no mangrove present, a maintenance-free zone of at least 10 feet separates the water from any landscaped areas Red (Rhizophora mangle) – Arching prop roots brace plant, trap silt, supply air to submerged roots – Long (pencil-like), green bean (curved) seed pods called propagules – Smooth & thick, elliptical leaves , dark green – No conspicuous glands at leaf base – Fragrant flowers especially spring and fall – Smoother, grayish-red bark compared to others – Ends of shoots have long and sharp pointed terminal bud Planting zone Shallows +0.5’ to -0.5’ Deep -3.0’ to -5.0’ Mid -0.5 to -3.0’ Adaptation Wet, moist soil Deep, brackish or fresh water White [Laguncularia racemosa) – Prefers higher ground (compared to red) – Two small visible glands base of each leaf used to excrete salt – Visibly rounded ends on each leaf – Less tree-like, more shrubby then red and black – Small white flowers in terminal clusters – Ribbed fruit that shaped like a spear-point – Produces short occasional root sprouts (shorter than Pneumatophores on Black) – Deeply furrowed bark Black (Avicennia germinans) – Leaves with smooth edges, shiny above, fuzzy below – White, fragrant flowers w/yellow center in clusters – Seed pods are leathery split lima bean or teardrops – Pneumatophores or breathing tubes for roots, vertical snorkels, no descending legs like red – Secrete salt found on surfaces of the leaves – Tall tree-like , usually black branches – Checker textured bark, sometimes black The Forest – Natural areas often find all three growing together – Maintain at any width. 8 feet to 50 feet wide – All are considered low maintenance, few pests – Trim mangroves properly October through March when mangroves are not growing as vigorously – Keep healthy, apply no fertilizer – Use as buffer to captures runoff & absorbs excess nutrients from land or water – Protects shoreline from wind, storm surge – Helps meet required water quality standards Use Native Plant Buffers w/Mangrove Salt- tolerant, beach plants Known plant associates with mangrove Plant
