What kind of world are we leaving to our children?
  • Less fish in the oceans
  • Fewer old forests
  • Depleted soils
  • Fewer species of animals and plants
  • A dangerously warming world
  • Is this progress?

3
Are we sending the wrong message?
  • Crime, pollution, sickness, greenhouse gases can
    make economy grow.
  • Longer work hours and stress make it grow
  • Distribution of income ignored

4
GDP and Natural Capital
  • GDP counts resource depletion as economic gain
    the more trees we cut, the more fish we sell, the
    faster we deplete our natural wealth the more
    the economy will grow, and the better off we
    are assumed to be.
  • Like factory owner selling machinery

5
In the Genuine Progress Index
  • Crime, pollution, sickness, greenhouse gas
    emissions, counted as costs not gain
  • Unpaid work, equity, free time valued
  • Natural resources are seen as capital assets
    subject to depreciation and requiring
    re-investment.

6
GPI Natural Resource Accounts Valuing Natural
Capital
  • For example, forest functions / values include
  • Preventing soil erosion and nutrient leaching
  • Protecting water quality and flows
  • Climate regulation/carbon sequestration
  • Providing habitat for the full array of native
    biodiversity
  • Recreation, tourism, aesthetic quality
  • Providing timber
  • Healthy Forest

Old Forests Store More Carbon A new study
published in Science, reported that ...
replacing old-growth forest by young stands ...
will lead to massive carbon losses to the
atmosphere mainly by replacing a large pool with
a minute pool of regrowth and by reducing the
flux into a permanent pool of soil organic
matter. (Schulze et. al. 2000)

Species vulnerable to clearcutting
  • Rare calicioid lichens absent from harvested
    stands (Selva 2001)
  • Four plant species found only in coastal old
    growth spruce forests (Moola and Vasseur 2001)
  • Northern and southern flying squirrels (Vernes
    2001 Gerrow 1996)
  • Moose (Snaith 2001)
  • Marten, fisher, and lynx
  • Trout (OBrien 1995)
  • Wood turtle (Herman 2001)
  • Red-backed and yellow-spotted salamanders, spring
    peepers, and wood frogs (Waldick and Freedman
    1999)

18
  • All hawks, especially goshawks, and broad-winged
    and red-tailed hawks (Staicier 2001 Gosse and
    Montevecchi 2001 Beaudette 2000)
  • Bicknells, Swainsons and Gray-cheeked thrushes
    (Rimmer 2001 Deal 1993 Thompson and Montevecchi
    1999)
  • Warblers Northern parula, Blackburnian,
    Tennessee, Magnolia, Bay-breasted, Black-throated
    green, Black-throated blue, Blackpoll, Black and
    white (Staicier 2001 Hobson and Bayne 2000
    Darveau et al. 1995 Deal 1993)
  • Pileated and black-backed woodpeckers, and
    yellow-bellied sapsuckers
  • Other birds Ovenbirds, Eastern wood-pewee,
    Red-eyed vireo, White-breasted nuthatch, Least
    flycatcher, Brown creeper
  • Arthropods (Kehler et al. 1996 Winchester and
    Ring 1996)

Clearcut harvesting and loss of natural age and
species diversity have resulted in loss of
  • valuable tree species
  • wide diameter and clear lumber that fetch premium
    market prices
  • resilience and resistance to insect infestation
  • wildlife sensitive to forest fragmentation and
    forest conversion
  • forest recreation and tourism opportunities

30
This represents a substantial depreciation of a
valuable natural capital asset.
  • degraded water quality and created unstable
    hydrological regimes
  • soil degradation and the leaching of nutrients
    that can affect future timber productivity
  • a substantial decline in carbon storage capacity
    a decline in other essential forest ecosystem
    services.

31
The Good News Volume 2 Best Forestry Practices
in N. S.
  • Selection harvesting increases forest value and
    provides more jobs
  • Shift to value-added creates more jobs
  • Restoration forestry is a good investment
  • What incentives can encourage restoration

32
Costs of Restoration
  • Pictou Landing 110/ha/yr
  • Frith 35/ha/yr
  • Dreschers estimates 80-150/ha/yr
  • Menominee Forest Enterprises 750-1,500/ha/yr
  • Algonquin Park 0.00
