Q

Adding beavers to ecosystems (Short term)

A

creates wetlands
stops flooding downstream
Kingfisher returns
kayaking might be more difficult

18
Q

Adding beavers to ecosystems (Long term)

A

Helps with climate change
Reduces flood risk
Animal species return
Tourism

19
Q

Epping Forest (deciduous forest north of London)

A

Home to many native trees(e.g. Oak,Elm Ash), insect, birds, amphibians, 177 species of moss and over 700 species of fungi
when leaves fall leave a nutrient rich layer

20
Q

Interdependence

A

Everything is linked

21
Q

Rainforest percents

A

20% of oxygen comes from rainforests.
25% of cancer curing drugs come from rainforests
50% of earths plants and animals come from rainforests

22
Q

Emergent

A

Around 50m high and are the habitat for the forests pollinators

23
Q

Canopy

A

Around 35m high and the most bio diverse layer of the rainforest. Most rainfall and 80% of sunlight is absorbed here it is quite windy.

24
Q

Under Canopy

A

Quite dense no wind and quite dim and dark

25
Q

Shrub layer

A

Plants grow on the forest floor and the shrub layer can be anything between thorny and open. There is a lot of leaf litter which decomposes quickly due to the constant heavy rain which leaves a nutrient rich topsoil. Many micro organisms and fungi help with decomposition.

26
Q

Biomass

A

all living things

27
Q

Adaptation

A

Actions taken to adjust to natural events such as climate change

28
Q

Biodiversity

A

Range of plants and animals in the world or a particular habitat. Biodiversity is important and desirable

29
Q

symbiotic

A

When a relationship between two animals mutually benefits both participants

30
Q

Buttress roots

A

large wide roots to give the tree stability.
They are quite shallow as rainforest soil is often lacking in nutrients due to leeching

31
Q

stilt roots

A

similar to buttress roots provide tall trees with support (less wide though) also stays quite shallow

32
Q

Lianas

A

Have roots in the ground and use other trees to grow into canopy to maximize sunlight. Many start in the canopy and send roots down to the ground

33
Q

Red leaves

A

Used to protect leaves from harsh sunlight

34
Q

leaf angling

A

Leaves arrange in specific ways to maximise sunlight

35
Q

tail drips

A

Leaves have a waxy texture so water doesn’t gather son algae doesn’t grow so it doesn’t harm the leaves ability to photosynthesize

36
Q

Epiphytes

A

plants that move on other plants (mostly trees) to make the most of the sunlight in the canopy layer

37
Q

Thin bark

A

Difficult for other plants to grow on bark. Also because of constant moisture is readily available thick,moisture preserving bark isn’t needed.

38
Q

Main causes of deforestation

A

Logging
Mining
Settlement growth
Road development
Farming(cash crops)
Cattle ranching
Hydro electric power

39
Q

Environmental impacts of deforestation

A

Causes 24% of greenhouse gases
4000-6000 species lost each year
80% of animals on earth would lose habitat
More soil erosion and flash floods
Less temperate climate worldwide

40
Q

Economic impacts of deforestation

A

Short term payout
Long term it isn’t sustainable

41
Q

Social impacts of deforestation

A

2 billion people worldwide rely on rainforests to survive
Also the indigenous tribes such as the Penan tribe would lose their culture

42
Q

5 Ws on the Penan tribe

A

Who= an indigenous tribe who live in harmony with the rainforest
What=Hunters who live off of the forest and feel safe there being moved out due to deforestation
Where= Borneo, Malaysia they aren’t exposed to the same viruses as outside
When= Now
Why= The Malaysian government is using the forest for many short term economic gains such as temporary jobs to help the economy fund infrastructure and mine valuable minerals rather than long term loses
