1
Potential for native species plantations in
carbon forestry
Sean C. Thomas Faculty of Forestry, University of
Toronto
2
Options for enhancing forest carbon sequestration

• Afforestation / reforestation
• Forest conservation
• Enhanced growth and yield through intensive
  forest management
• Increased rotation length
• Changes in species/genotype
• Stand conversion
• Shift from even- to uneven-aged management

3
Socio-economic evaluation Favorable prices for
hardwoods
(Local prices for large-dimension, high quality
logs)

• Tilia mandshurica 2,010 Yuan/m3
• Fraxinus mongolica 1,380 Yuan/m3
• Quercus mongolica 1,370 Yuan/m3
• Betula dahurica 1,260 Yuan/m3
• Populus davidiana 1,040 Yuan/m3
• Pinus koraiensis 1,000 Yuan/m3
• Picea spp. 800 Yuan/m3
• Larix spp. 650 Yuan/m3

3.Field Data Collection of Forest Stands in Liping

• 4 forest stand types
• Chinese fir, mansson pine, mao-bamboo, natural
  secondary broadleaved forests
• 23 Age stages for each forest type
• 3 Plots for each stand
• MeasurementsDBH,Height,Volume,core,Leaf angle to
  the stem

Grain-to-green Ecological Program
plots in Liping County
plots in Puding County
13
The Properties of Karst forest habitat

• High surface rock exposure(gt80), separate soil
  body
• Shallow topsoil layer, rich in calcium and higher
  pH value(7.28.0)
• High water deficit, low moisture keeping capacity

14
The structural and functional properties of
primitive karst forests

• High species diversity (7680species/30m30m)
• Low ecological dominance,
• infinite predominant species
• community height 38m, small diameter and low
  biomass
• (100150t/hm2)
• Relatively fragile, low resistance ability to
  human disturbance

15

• Tea Plantation
