Non-timber forest financial value

  • extractive - financial or economic value
    • fuel
    • lumber
    • pulp for paper
    • mining
    • hunting?
  • non-extractive economic value
    • recreation
  • ecosystem services
    • water reserves
    • others

Carbon budgets

  • Systems view:
    • reducing carbon into the atmosphere by:
    • maintaining carbon storage in current forests
    • decreasing carbon released during deforestation or degradation of ecosystem (soil loss, etc)
    • increasing carbon taken up during growth of a forest (such as those previously cut)
  • Accounting -
    • what information do we need to make a decision and what system do we set up to get that information?
    • we don't want to miss anything - "completeness"
      • example - leakage
      • carbon is sequestered in one place but is just being released somewhere else
    • we don't want to double count anything either
      • new carbon take up can't also be counted as what is already stored
      • don't get to count the leaves when they're on the tree and also soil accumulation that year (from falling leaves)

Management for Carbon

  • FIRE
    • forests as a sink for carbon
    • need to count how much is lost to wildfires compared to how much is lost to controlled burns
    • use simulation models with different treatments to explore the outcomes
    • without wildfire - control (no action) had largest carbon stored
    • with wildfire - control had the most emmissions from fire and the least stored in trees
    • control burns - intermdediate
    • best - push forest to low-density stand of fire resistant pines
  • LOGGING METHODS
    • tropical forest
    • represent about half of the 558 Pg carbon stored in all vegetation
      • Peta gram (10^15 g) - 1 metric ton = 10^6 g
      • 558 billion metric tons
    • selective logging may loose upto 70% of storage potential (damage)
    • 20 years of study and then extrapolating
    • use of intensive timber stand improvements
      • getting rid of bad trees, selective harvest
      • forest carbon recovered in 45 years after logging
      • without TSI - 100 years to recover carbon lost

Managing for forest ecological integrity

  • composition
  • structure
  • function
  • as compared to its natural or historical range of variation
  • large forests and parks compared to smaller historical parks
  • report the results green, yellow, red - stoplight metaphor
  • in the context of global climate change
    • rapid change of climate doesn't allow time for the forests to adapt to new composition
    • climate models predict NH will have the climate of either Virginia or N. Carolina under low and high CO2 emission scenarios (TNC - Winter 2009)

Several Case Studies of REDD

  • carbon emissions from deforestation accounts for 17 to 18% of global carbon emissions
    • that's more than all vehicles (13%)
  • planting new trees counts but not cutting down forests doesn't count - until REDD
  • some countries have already preserved their forests (how can that count)
  • country (or larger) level of accounting is needed to avoid leakage
  • in Brazil, 90% of deforestation is illegal - how can that be controlled?
  • land tenure - ownership by local people is a real problem
  • Economist - although REDD has risks there are more risks with continued deforestation
    • (reverse statement of the precautionary principle - i.e. we know what we are doing is bad, try something else)

 

  • Bolivia
  • N. California
  • Indonesia

Some interesting facts:

  • young redwood forests in California that are growing can take up about 3 tons CO2 per year per acre
  • can hold 500 tons per acre total
  • a car produces about 5 tons per year
  • Pacific Corp has agreed to pay about $10/ton
