• Photographic Record
Within the sampled reclamation area, representative color photographs were taken to
document the appearance of the vegetation in 1997. Within each photo, a placard identifies the
reclamation area being illustrated.
Statistical Methods
Sample adequacy calculations were carried out using the formula as prescribed by CMLRB
(1988):
tz s2
Nmin =
dZ xz
where:
t = two-tailed t-value with n-1 degrees of freedom
s2 = sample variance (based s~.,)
d = 0.1 (level of precision or desired detectable reduction)
x =sample mean
• Climatic Data
Precipitation data from the Seneca II-W Mine for the period of January 1992 through July 1997
were provided by SCC. Since the long-term average for the mine exists for a relatively short
time, the long term average monthly precipitation data from the National Oceanic and
Atmospheric Administration (NOAA) for the nearby town of Hayden was used as an appropriate
base for comparison. Information on degree-days was also derived from the NOAA records at
Hayden.
