STPACE: Beginning pace of a segment.
ALONG: Distance from the start of the segment to the individual (in cm?). This is measured for 1988 tagged individuals (seedlings and saplings) who were still alive in 1998, but some are missing. NOT measured for 1989 tagged individuals. Measured for 1998/1999 tagged individuals. "double" variable with 2396 unique values in the range [-5.1, 39.52], 852 NA values.

.
PEX89: Extension growth in 1989 for 1989 tagged plants. This might not be a full year of extension growth, so prefixed with 'P' for partial.
EX88: Extension growth measured in cm. In 1988, only collected extension growth for as many as 10 years from 1987-1978. In 1989, starting with PE1989
, extension growth was measured for as many years as possible for all seedlings; for saplings, extension growth was measured for as many years as possible only on the first plant of each species encountered on segment. The second and third saplings of each species in each segment only had 10 years of extension growth measured.

EXCNT88: Number of extension growths measured.

should be missing, trust the EX
s.
BRS: Browsed off (renamed this from BR to BRS to better distinguish with "broken"). If PEX99

should be missing. All other ext. growths are not reliable for the year. If PEX99
> 0, then retain the extension growth data, and all ext. growths are not reliable for the year.
BK: Broken. If PEX99
== 0, PEX99
should be missing. All other ext. growths are not reliable for the year. If PEX99

This is the distance remaining from the last positively identified growth measurement to the root collar for seedlings; and distance remaining from the tenth ext. growth to the root collar if more than 10 years of ext. growth were recognizable, or the distance remaining from the last positively identified ext. growths to the root collar if less than 10 years of ext. growth were measured.
