 Conclusion
Topic B4. Slide 3 of 32
• Wetlands and mangroves cover 6-9% of global land area
• Despite their small area, wetlands provide many
benefits for human populations
• These benefits are called “ecosystem services”

Ecosystem Services
 Resources and processes supplied by natural
ecosystems that benefit humans

1. Supporting
Natural processes that support all other tropical wetland ecosystem
services
• tree growth
• nutrient cycling
• water cycle

Topic B4. Slide 10 of 32
2. Biological: plant
Sonneratia mangroves trees can grow
in very salty water
Nypa palm mangroves trees
cannot growin salty water, they
like freshwater
Wetlands have many kinds or SPECIES of
plants, fish, and animals (Tomlinson 1986;
Nagelkerken et al, 2008)
Topic B4. Slide 11 of 32
Prop roots
Mangrove tree species: Rhizophora apiculata
Topic B4. Slide 12 of 32
2. Biological: fish, shrimp, crabs
The roots, trunks, and other plant structures within
tropical wetlands and mangroves provide areas that
can used by many species of fish, shrimp, and crabs
when the wetlands are flooded with water
(Primavera 1998; MacKenzie and Dionne, 2008).

2. Biological: fish
pneumatophores
knee roots
prop roots

Different types of roots provide different levels of protection. Smaller spaces within
pneumatophores and knee roots provide excellent hiding places for small fish. Prop roots also
provide hiding places, but can also allow larger fish to access (MacKenzie and Cormier, 2012.

2.
Biological: fish
More fish are usually found in ocean areas that are next to mangroves compared to ocean areas
where there are no mangroves or where mangroves have been cut down.

2.
Biological: fish
Leaf litter from wetland plants and
mangrove trees are an important food
source for crabs and shrimp.
Topic B4. Slide 16 of 32
2. Biological: fish
These crabs and shrimp are also important food
for many species of birds and other animals.

of human beings (Carpenter et al., 2009)

• Spiritual
• Recreational
• Educational
• Ecotourism
• Inspiration for music & art

development and cultural advancement of people

Conclusion
Wetlands are important ecosystems that
provide a variety of valuable ecosystems
services to the human populations that rely on
them. These services include many different
kinds of supporting, biological, provisioning,
regulatory, and cultural services. This
underscores the importance of wetlands and
the need to protectand conserve wetlands
around the globe. While wetland restoration is
also a much needed and important approach to
wetland conservation, prevention of wetland
loss is the best strategy to protect wetlands and
maintain the many services that they provide.
