Forestry And Woodlands: Introduction To Forestry

Front 1

What is a forest?

Back 1

Land with tree cover of more than 10% and an area of more than 0.5 ha. Trees should be able to grow to 5m at maturity.

Front 2

Why don't forests grow everywhere?

Back 2

• Global Atmospheric Circulation
• Species with similar ecological tolerances, structure and functional characteristics.
• Biomes - Robert Whittaker's classification of biomes.

Front 3

What do forests need to grow?

Back 3

• Climate
• Soil
• Biodiversity
• Time

Front 4

What do plants need to grow?

Back 4

• Carbon dioxide
  
• Light
• Water
• Nutrients

Front 5

What are the major biogeochemical cycles?

Back 5

• Carbon cycle
  
• Hydrological cycle
• Nitrogen cycle

Front 6

How do the major biogeochemical cycles relate to forestry?

Back 6

• Forests are carbon sinks and hold onto atmospheric carbon, and then release it when they are harvested or in forest fires.
  
• Forests need water to grow and absorb it.
• Forests need nitrogen to grow and absorb it through there roots.

Front 7

What is primary growth?

Back 7

Primary growth extends the length of plant above and below ground and comes from the apical meristem.

Front 8

What is secondary growth?

Back 8

Secondary growth refers to the lateral growth or width of the plant from the lateral meristems.

Front 9

What types of competition do trees face?

Back 9

• Physical and chemical i.e water and nutrients and light.
  
• Predation, parasitism, symbiosis.

Front 10

What are the 4 categories of ecosystem services? and give examples.

Back 10

• Supporting - nutrient cycling, soil formation.
• Provisioning - food, fresh water, wood and fibre, fuel.
• Regulating - climate, disease, water purification.
• Cultural - aesthetic, spiritual, educational, recreational.
