coastal kati Flashcards
cr features
-hosting thousands of marine species, including fish, mollusks, and crustaceans.
-act as natural barriers, protecting coastlines from storms and erosion.
cr threats
-climate change (coral bleaching)
-overfishing
-pollution-sewage
cr management
-global organisation
-sustainable fishing practices to preserve
-national protection areas
-restricted access
cr adaptations
- algae uses sunlight to photosynthesise and provide food for coral
-hard skeletons to protect themselves from predators and strong currents.
cr conditions for growth
-thrive in warm waters (23-29°C)
-need plenty of sunlight (up to 30m depth)
-require clear, saltwater conditions with low nutrients.
cr distribution
-all over the world
-primarily found in shallow, tropical waters near the equator
- between tropics of cancer and Capricorn
-indopacific region, Southeast Asia, pacific, Atlantic and carribean
mangrove features
-intertidal
- exist in saltwater and freshwater
man threats
-deforestation
-invasive species
-development and building
man adaptations
-specialized roots that allow them access to oxygen in waterlogged soils.
man management
-prevent erosion (barrier)
-water filtration system
man conditions for growth
-saline environments with slow-moving waters where fine sediments accumulate.
man distributuon
-tropical and subtropical regions, -typically found along sheltered coastlines, riverbanks, estuaries
sd features
-found along coastlines, deserts, and inland areas with a supply of sand and strong prevailing winds
-eg ahyara desert
sd threats
-human activity (construction, tourism)
-natural erosion threaten sand dunes
-Climate change, with rising sea levels, stronger storms pose a risk to their stability
sd conditiond for growth
-supply (accumulation) of mud and shingle, strong winds to move the sand, and vegetation to trap and stabilize the sand particles.
sd managment
-build boardwalks limit human trampling
-plant vegetation-stabilize dunes -fence off sensitive areas
sd adaptations
-plants like marram grass grow on dunes
-roots help hold the sand in place, they can survive salty and dry conditions.
sd distribution
typically found along coastlines, deserts, inland areas with supply of sand and strong prevailing winds
sm features
-act as buffers against coastal flooding
- absorb pollutants
- provide vital habitats for birds from behind a spit
sm threats
-Developmentand housing -agriculture
-pollution
sm adaptations
-Salt marsh plants, like cordgrass, can handle salty and flooded conditions. -have long roots to keep them stable
sm management
-setting up wetlands
-restoring damaged areas with plants.
sm conditions for growth
-require low-energy environments where fine sediments can settle
-thrive in brackish water
-depend on regular tidal flooding.
sm distribution
-found in temperate and subpolar regions, often along coastlines and estuaries
