FIA, the keystone of
Criterion 2, has reported
on U.S. forests from local to global

Make no mistake ….
Criterion 2 is about commodities,
timber and nontimber
However, looking holistically…
Indicators 1-4 in Criterion 1 cover area of all forest by type
and successional stage and indicators 7 and 9 cover species
abundance and change in forests
Indicator 26 in Criterion 5 covers biomass in forests by type
[and I would suggest some parallelism with Criterion 1]
Forest Inventory and Analysis
The Nation’s Forest Census
In the 2003 National Report on Sustainable Forests for Criterion 2:
Forest Inventory and Analysis
The Nation’s Forest Census
Indicators
2, 4, 10, 11, 12, 13, 31
What are we doing about Criterion 2 gaps?
Annualized forest inventory is progressing

Forest Inventory and Analysis
The Nation’s Forest Census
And, coming soon to a website near you:

Annual estimates of area, growth, removals and
mortality for all forest land, current and historic

Annual estimates of volume and biomass on all
forest land

Annual updates on forest ownership study results

Annual validation data for spatial tools based on
remote sensing [15-20,000 plots per year]

Indicator 2
We need to explore surrogates for age-class like average stand diameter?
The optimal mix of forests of
different average size trees is
difficult to define and depends
greatly on management
objectives. Clearly, the effects
of human activity and natural
events paint different pictures
in different regions.

Indicators 2 & 4
If we had known then….
FIA would have cataloged area by forest by type
and average diameter class (stand-size class)
jointly
FIA did it separately for 50 years and it is
difficult to recover from pre-digital data.
We have data from about 1980 on.

Fusing field and remote sensing data will offer new
opportunities for displaying patterns like ownership

questions
remain

Like number of hardwood trees in the U.S. by major species, 1963-2002
Even when we have trends, what do they mean?

Does ownership matter?
As public policy
has shifted,
removals have
moved
dramatically
from public
land in the West
to private land
in the East in
the last 15
years.
