Baker’s (2006) chief criticism of Fulé et al. (2003) is that
they fail to acknowledge the alternate interpretations of their own data. Baker
asserts that fire scar reconstructions, like all disciplines, have undergone a
certain recalibration to tune the validity of their methods. Baker assessed the
data presented by Fulé et al. (2003) and arrived at a very different conclusion
than the original authors because Baker 1) made comparisons between the mean
CFI for all four study sites and the estimated fire return interval and 2) used
evidence of even-aged trees stands and other available data to induct a fire history
with high-severity fires. Fulé et al. (2003) apparently made several
assumptions (such as the absence of severe fires in the site) and calculated
return interval estimates with pooled data, leading them to what Baker avows as
erroneous conclusion about the site’s fire legacy. Baker’s assessment of the
Fulé et al. (2003) study differed by a factor of 10. While Baker acknowledges that
Fulé et al. (2003) might be correct, he maintains his own valuation is just as
(if not more) valid.
How fire history is measured and how those measurements are construed
matter because these findings are what influence land management. Best
management practices are increasingly founded on scientific research derived
from empirical evidence. However, if evidence is interpreted erroneously it
could have deleterious effects on landscapes, their processes, and
biodiversity. While the final decisions regarding fire regime restoration lie
with land managers, researchers also bear responsibility for the version of
reality they present to laypeople.
