P1B 18Mangrove management

What role do mangrove forests play in tourism?

• They are primarily used for agriculture.

• They provide jobs and income for locals.

• They are a source of freshwater.

• They serve as a habitat for domestic animals.

What are the uses of mangrove wood?

• It is primarily used for making furniture.

• It is resistant to rot and insects, valuable for construction, fuel, pulp, woodchip, and charcoal production.

• It is mainly used for decorative purposes.

• It is used exclusively for making paper.

What are mangrove forests?

• Ecosystems that thrive in freshwater lakes

• Salt-tolerant ecosystems found in the intertidal zone of tropical coasts

• Forests that grow in mountainous regions

• Deserts that support unique plant species

How are local communities involved in mangrove management in the Sundarbans?

• Locals are incorporated into management programs, provided with alternative incomes, and trained as forest guards.

• Local communities are excluded from management decisions to ensure better conservation.

• Only government officials manage the mangroves without local input.

• Local communities are only allowed to collect firewood from the mangroves.

How do mangrove forests support fisheries?

• They provide a habitat for various marine species and serve as breeding grounds.

• They are primarily used for timber production and do not support fisheries.

• They filter pollutants from the water, making it safer for fish.

• They serve as home to a variety of fish, crab, shrimp, and mollusc species and act as nurseries for many fish species.

How does clearing affect mangrove forests?

• Mangroves are cleared for shrimp aquaculture, tourist resorts, human settlements, harbours, and industrial areas.

• Mangroves are preserved for biodiversity and ecosystem services.

• Mangroves are cleared to increase agricultural land for crops.

• Mangroves are planted to combat coastal erosion.

How does the destruction of coral reefs affect mangrove forests?

• It allows more sunlight to reach the mangroves, promoting their growth.

• Damaged coral reefs lead to stronger waves reaching the coast, undermining sediment and preventing mangrove seedlings from taking root.

• Coral destruction increases fish populations that help mangroves thrive.

• It has no significant impact on mangrove forests.

What is an example of effective mangrove management?

• The Sundarbans, the largest mangrove forest, is managed by incorporating local communities, reforestation projects, and alternative livelihoods.

• The Amazon Rainforest is primarily managed through logging and agriculture.

• Mangroves are best managed by removing all human activity from the area.

• The coastal areas are protected by building concrete barriers and preventing any natural growth.

Where are mangrove forests typically found?

• In the intertidal zone along 25% of tropical coasts

• In the mountainous regions of temperate zones

• In the deserts of North Africa

• In the Arctic tundra

How do mangrove forests protect coastlines?

• They provide habitat for marine life.

• Their dense root systems trap sediments, stabilize coastlines, prevent erosion, and protect coral reefs from sediment.

• They absorb excess nutrients from the water.

• They serve as a barrier against strong winds.
