What is wetland restoration?
Wetland restoration is the sustainable rehabilitation of wetland areas in order to restore the wetland back to its' previous condition before either natural or human change.
1 of 20
Benefits to the carbon cycle of wetland restoration.
Increased carbon storage due to increased vegetation.
Protect soil carbon storage as they stabilise the soils meaning less carbon escapes to the atmosphere.
2 of 20
Benefits to the water cycle of wetland restoration.
provides an established store in between rivers and run-off which decreases the chances of flooding and adds established stores.
Increased evapotranspiration due to the plants losing water to the heat.
3 of 20
What % of the world's carbon do wetlands hold?
Up to a third.
4 of 20
What is an example of wetland restoration?
Goss Moor Nature Reserve, Cornwall.

What is the aim of the wetland restoration project?
They aim to stabilise the water table and send water back to the River Fel which hasn't been happening due to agriculture.
6 of 20
How has the wetland restoration project attempted to achieve their aim?
They have used flow directors on rivers to encourage the discharge of water,
use bundles of willow to permanently block water.
Added more vegetation so cattle can be introduced who can help to shape the wetland.
plan to re-introduce beavers.

What are some challenges with wetland restoration?
requires a large amount of space which could be used for urban development or agriculture.
Requires a lot of local knowledge which increases the people needed and makes projects longer.

Define afforestation.
Afforestation is the process of restoring previously threatened ecosystems which have become so due to deforestation or desertification for example.
9 of 20
Benefits to the Water cycle.
Increases interception which reduces surface run off.
Will break up the soil therefore increasing infiltration and percolation which will refill aquifers and reduce the risk of flooding.
10 of 20
Benefits to the carbon cycle.
Trees remove carbon from the atmosphere due to photosynthesis. Thus reducing the effects of climate change.
They also can help to restore habitats which can mean that decomposition can increase which will make soils more fertile.

What are some problems with afforestation projects?
The act of afforestation has been used by many companies as a loop hole for them to justify for poor action on climate change.
Afforestation can cost $200 per acre which can discourage companies.
Afforestation can create a monoculture too.

What is an example of an afforestation project?
Mersy Forest.
13 of 20
How has an afforestation project attempted to achieve their goals?
The Mersy Forest has worked with surrounding councils and organisations in order to increase rates of afforestation.
They also have introduced floating islands and green walls to spread the message and add to their productivity.

Define no-till farming.
the act of not tilling the soil in order to avoid oxidising the carbon within by turning it over,
15 of 20
What are some issues with no-till farming?
The initial cost of equipment is high, gullies may form in the farm.
The learning curve for the process is higher, making it more expensive and time-consuming.
16 of 20
Define silvopasture.
The process of integrating trees, animals and other plants for mutual gain of all members within the ecosystem.
17 of 20
Benefits of regenerative agriculture for the water cycle.
Progressive cattle grazing can help as cows are rotated around which allows for the grass to grow back which increases interception as grass is growing faster, reducing surface run off.
18 of 20
Benefits of regenerative agriculture to the carbon cycle
Growth of more resilient crops help to maintain steady CO2 sequestration. Vegetation can absorb 25x more carbon than soil.
19 of 20
What is an example of regenerative agriculture?
Bec-Hellouin is a French farm which integrates wildlife with farms in a tiered system. They plant in random locations, ensuring more biodiversity and healthier soils.
