25
How many hectares of land in the UK is moorland?
350,000
26
Where in the UK are moorlands usually found?
Upland areas - mostly in Scotland
27
What sort of plants is in the moorland?
Rough grasslands, low-growing crops like heather
28
Where in the UK are heaths found?
Lowland areas
29
Why are heathlands important?
Often provide habitats to rare species, like the sand lizard
30
Where are wetlands usually located?
East Anglia, Scotland
31
What is the plant life of wetlands like?
Waterlogged soils, low in nutrients with distinctive plants such as bog mosses
32
What percentage of the UK is woodland?
12%
33
How many tourists are estimated to visit the UK coastline each year?
250 million
34
Name 2 examples of abiotic factors.
Climate, soil, water
35
What store is the largest in the nutrient cycle in the TRF?
Biomass
36
Why are nutrients recycled quickly in the TRF?
Year-round plant growth, rapid decomposition
37
What are smaller stores in the nutrient cycle of the TRF?
Soil, litter
38
Name, from top to bottom, the layers of the rainforest.
1. Emergent layer 2. Canopy 3. Sub-canopy 4. Shrub layer 5. Herb layer
39
Name one way animals have adapted to the TRF.
E.g: monkeys have strong hands and feet to travel across trees in canopy and emergent layer
40
Name 3 examples of goods provided by the TRF.
Timber, foods, plant species for medicine…
41
Name 3 examples of services provided by the TRF.
Home for indigenous tribes, carbon store (absorbs 2 billion tonnes a year), revenue
42
Name 2 ways climate change could affect the TRF.
Reduced biodiversity, cloud functioning, etc.
43
How much of Madagascar is forested now, compared to 1950?
20% - half the amount of 1950
44
Why is there deforestation in Madagascar?
Tavy (agriculture), logging, population growth…
45
Name an example of government sustainable rainforest management strategies have been implemented in Madagascar.
Association Mitsinjo
46
What industry contributes heavily to the income of Association Mitsinjo?
Tourism
47
How does Association Mitsinjo reduce deforestation? Has it been successful?
Members are paid for patrol the rainforst for illegal logging and hunting. It has been successful.
48
How is Association Mitsinjo restoring the rainforest?
In return for improved crop yield, farmers set aside land to grow rainforest.
49
How many new trees have been planted due to Association Mitsinjo?
1 million
50
How has Association Mitsinjo had social impacts?
Educating farmers on sustainability, funded local healthcare and environmental education
51
What are 2 disadvantages to Association Mitsinjo?
1. Those not in the Association are still using logging/unsustainable practices 2. It relies on aid
52
Name 2 ways the Amazon rainforest is being sustainably managed.
The government has offered grants to timber for logging companies in specific areas, carried out surveys to see which areas need the most protection, reduced-impact logging is more profitable and offers protection to the TRF…
53
Name 2 biotic characteristics of the deciduous woodland.
Deep, fertile soil created by annual leaf fall, slow leaching of nutrients and bogs, ponds provide habitats for plants and animals, etc.
54
In the nutrient cycle in TDW, which stores are a similar size?
Soil, biomass are a similar size
55
Why is the soil in TDW fertile?
1. Annual leaf fall adds a lot of nutrients to the soil 2. Colder temperatures in winter result in less decomposition than in spring
56
Name, from top to bottom, the layers of the deciduous woodland.
1. Canopy 2. Sun-canopy 3. Ground layer 4. Herb layer
57
Name 2 reasons TDW has lower biodiversity than the TRF.
1. Smaller ecosystem so less space for organisms 2. Lower food preduction in winter 3. Located at higher latitude -> lower temperatures and less sunlight, so less photosynthesis Etc.
58
Name 2 adaptations of plants in the deciduous woodland.
1. Deciduous trees drop leaves in autumn to conserve water during in colder winter months 2. Trees spread branches to access sunlight 3. Trees have large, deep roots for stability and to access nutrients Etc.
59
Name 2 adaptations of animals in the deciduous woodland.
1. Birds migrate in winter to warmer conditions 2. Squirrels store food for winter 3. Some animals hibernate to survive harsh winters
60
Name 2 goods provided by TDW.
Fuel, timber, non-timber forest products, etc.
61
Name 2 services provided by TDW.
Recreation, carbon store, conservation, etc.
62
How many people live in the New Forest area?
175,000
63
How many tourists are attracted by the New Forest National Park each year?
15 million
64
Name 3 challenges to sustainability posed in the New Forest area.
1. Erosion of paths 2. Increased pollution 3. Timber extraction 4. 40% of woodland privately owned and often unmanaged Etc.
65
Name 3 ways the Green Leaf Tourism Scheme has impacted New Forest.
1. Promotes the use of local products. In return, businesses give a percentage for local wildlife conservation and encourage visitors to walk or use bikes. 2. Sustainable transport schemes to reduce congestion, air pollution 3. Landowners provided funding to plant native tree species 4. Tree felling controlled - older trees felled more than younger
66
How successful has the sustainable management of New Forest been?
Reduced damage to ecosystem, particularly by tourists and reduced deforestation
