1/5 Introduction: ecological restoration

2/5 Objectives 8

Sort the different concepts related to the anthropogenic changes

2/5 Objectives 9

Sort the different concepts related to the anthropogenic changes

1) What are the alternatives for an anthropised ecosystem or

landscape?

/ What are the different end points of a restoration process?

2/5 Objectives 10

Sort the different concepts related to the anthropogenic changes

1) What are the alternatives for an anthropised ecosystem or

landscape?

/ What are the different end points of a restoration process?

2) Measure the increase or decrease of anthropogenic effect

Measure of the difference between a reference natural state

and an anthropised one

3/5 Reference concepts 13

Naturalness:

state of the system when no human activity has influenced it

3/5 Reference concepts 14

Naturalness:

state of the system when no human activity has influenced it

Reference state of naturalness

= departure point to measure anthropisation

= goal to achieve while restoring
