Here is a link from New Sceintist which summarises the economic value of ecosystems globally, How Much Would You Pay For Planet Earth?
Here is a snippet from the article:
The cash value of Earth's biomes
Values are in dollars per hectare per year. The range represents the different values of biomes of each type around the world, with the top end of each range corresponding to prime locations (Source: TEEB)
Coral reefs (tropical and subtropical): $14 - $1,195,000
Key values: tourism, storm protection, fish nurseries
Coastal wetlands: $2000 - $215,000
Key values: waste purification, fish nurseries, storm protection
Other coastal systems: $248 - $80,000
Key values: tourism, fish nurseries
Inland wetlands: $1000 - $45,000
Key values: natural water reservoirs, waste treatment
Rivers and lakes: $1800 - $13,000
Key values: water supply, waste treatment, tourism
Tropical forests: $91 - $23,000
Key values: climate regulation, gene banks (for medicinal plants, for example), erosion prevention
Temperate and boreal forests: $30 - $4900
Key values: Food, gene banks, watershed protection
Woodlands: $16 - $2000
Key values: timber and other forest products, waste treatment
Grasslands: $300 - $3100
Key values: climate regulation, watershed protection
