16
Q

National park

A

An area mostly in natural state that is managed to protect biodiversity

17
Q

Sustainable forestry

A

Ways of harvesting forest without damaging it in the long-term

18
Q

Geographical conflict

A

Disagreement and differences of opinion linked to the use of places
and resources

19
Q

Sustainable forest management

A

This is about conserving forests by ensuring they are not used faster than
thev can be renewed.

20
Q

Agroforestry

A

Growing trees and crops together. Some crops benefit from the shelter
of the tree canopy. Trees also prevent soil erosion and crops benefit
from the nutrients in the leaf litter.

21
Q

Clearcutting

A

This is the logging of all trees in a wide area of forest.

22
Q

Selective logging

A

Trees are only cut down when they reach a certain height. Young trees
are allowed to mature so the height of the canopy is maintained. It only
moves large, valuable trees and leaves some of the forest intact.

23
Q

Afforestation

A

The replanting of trees to replace the original, primary forest that has
been lost. This method does not maintain the biodiversity of a natural
forest.

24
Q

Protecting areas

A

Just like in Costa Rica, this is simply about giving places legal protection
and enacting tight laws that stop deforestation in certain places.

25
Q

Sustainability

A

Sustainability ensures that future generations can access the
environment, while current generations use it effectively for social,
economic and environmental gain

26
Q

CITES

A

The Convention on international trade in endangered species
CITES bans cross-border trade in certain species

27
Q

REDD

A

RED - Reducing emissions from deforestation and forest degradation
A United Nations project whose purpose it is to stop deforestation

28
Q

Sustainable forest management

A

This is about conserving forests by ensuring they are not used faster than
they can be renewed.

29
Q

Agroforestry

A

Growing trees and crops together. Some crops benefit from the shelter
of the tree canopy. Trees also prevent soil erosion and crops benefit
from the nutrients in the leaf litter.

30
Q

Monitoring

A

Satellite technology and photos are used to ensure that no illegal
activities are taking place and that landowners follow guidelines for
sustainability.

31
Q

Indirect threat

A

Caused by global warming/pollution - e.g. increased CO2 levels

32
Q

Intact forests

A

These are primary forests that have never been deforested.

33
Q

Direct threat

A

clear link between one thing happening and the damage being caused
to something else - deliberately cutting down trees

34
Q

Taiga or boreal forest

A

Taiga is Russian for forest. The world’s largest biome made up on
coniferous trees that have adapted to a cold climate. It has a n extreme subarctic climate. Biodiversity is low

35
Q

Biodiversity

A

 The variety of plant and animal life in the world or in a particular habitat,
a high level of which is usually considered to be important and desirable

36
Q

Net primary productivity

A

This is a measure of how much new plant and animal growth or biomass
is added to a biome each year. It is measured in grams per square metre per year
