-strip felling
-education
-ecotourism

Question 18

FSC labelling systems - what is it?

Answer 18

stamp on wooden products to say that the wood has come from a sustainable source

Question 19

advantages of FSC labelling systems

Answer 19

-can be internationally recognised
-consumers can easily recognise it
-gets the people buying the furniture to think before buying

Question 20

disadvantages of FSC labelling systems

Answer 20

-timber companies pay FSC assessors to assess their wood company, the assessor wants to have a good reputation so that they get hired more so they may pass timber companies that don’t actually comply with the regulations
-some plantations have been certified even though they damage the environment
-only certifies primary forests

Question 21

agroforestry- what is it?

Answer 21

growing trees and crops at the same time

Question 22

advantages of agroforestry

Answer 22

-prevents soil erosion
-increases crop yields
-increases biodiversity
-creates effective short term cash flow

Question 23

disadvantages of agroforestry

Answer 23

-very labour intensive
-daily farming issues are far more complex
-agroforests often see reduced crop yields because smaller crops would have to compete with the taller trees for light, nutrients and water

Question 24

selective logging- what is it?

Answer 24

trees are only felled when they reach a particular age

Question 25

advantages of selective logging

Answer 25

-allows young trees a guaranteed life span and the forest will regain full maturity after around 30-50 years

Question 26

disadvantages of selective logging

Answer 26

-lose most healthy trees
-regrowth often proved difficult
-can be very harmful for trees
-as old tree fall it harms and destroys small trees around

Question 27

trekasaw- what is it?

Answer 27

portable saw that can be taken into the forest

Question 28

advantages of trekasaw

Answer 28

-can cut trees into manageable sections that allows trees to be taken out of the forest without destroying more trees

Question 29

disadvantages of trekasaw

Answer 29

-is nothing like as efficient as a saw mill
- can not cope with the very largest trees

Question 30

afforestation- what is it?

Answer 30

-the opposite of deforestation, if trees are cut down they are replaced to maintain the canopy

Question 31

advantages of afforestation

Answer 31

-grows trees that provide wildlife habitats
-increases supply of timber and charcoal
