3b Flashcards
Influence of European vegetation
- Postglacial development of vegetation
2. Direct and indirect human influence
Postglacial development of vegetation
Most species have migrated north due to the receding ice
Species came from the Mediterranean
Direct and indirect human influenc
Would have potentially had forests everywhere but in extreme climatic conditions
Vegetation communities due to deforestation and grazing
May have caused extinction of large mammals in Europe
May indirect I.e climate change, pollution
Neolithic revolution
Agriculture spreading from SE to NW
Little pollen analytical evidence
Forrest were burnt to grow cereals
Manure as fertiliser
Iron Age
Increase human impact due to metal tools
Increasing cutting in mountainous areas
Roman period
Increase population density + construction of roads and cities
Introduction of fruit trees and wine grapes in Mediterranean
Medieval period
Preferred cultivation of rye
Poorly wooded landscapes
Park like grazing landscapes
Industrial revolution
Reforestation
Pollution
Heavy machinery
Land reclamation
River damming
Consequence of clear cutting and agriculture
Overexploitation of health
Grassland + beech swamp
Soil erosion = forming inland dunes
Removing trees in sandy soils enables the soil to become more mobile preventing new trees from developing
