Tropical rainforest and sustainable management Flashcards
What is natural vegetation?
Natural vegetation is plant life that covers certain part of the world’s area and develops without human interference.
What is tropical climate?
Tropical climate is the average weather conditions of a place over a period of time, usually 30 years.

What is the similarities and differences between weather and climate?
Similarity: They both use the same atmospheric elements.
Difference: The time-scale of observation
What is a tropical rainforest?
The main type of vegetation found in parts of the world that experience tropical climate.
- Receives abundant sunlight
- High rainfall
Forest structure:
Emergent layer, Canopy layer, under storey, shrub layer, forest floor
Adaptation to environment:
-Broad leaves
-Waxy leaves
-Drip Tips
-Buttress Root
What are mangroves forests?
Unique natural vegetation found along/very close to the coast.
What are the environments that mangroves require to grow in?
- Experience tropical climate:
- Average air
- Water temperatures not below 20 degrees
- Calm water conditions
Characteristics of mangroves:
- Relatively uniform in height
- Horizontal distribution
What is horizontal distribution?
Distribution of plants in speicifc areas accrording to certain parameters, each characterised by the dominant species.
Adaptations of mangroves:
- Salt-secreting leaves
- Salt-excluding roots
- Aerial roots (soil is waterlogged, very poor in oxygen, soft and unstable)
Characteristics of Aeiral roots:
- All grow partially above the soil surface
- Anchor mangrove to the soft soil
