The following mortality and removals queries are returning incorrect summaries in EVALIDator.
Average annual mortality of growing-stock trees (at least 5 inches d.b.h.), in cubic feet, on forest land
Average annual harvest removals of growing-stock trees (at least 5 inches d.b.h.), in cubic feet, on forest land
Average annual other removals of sawtimber trees, in board feet (International 1/4-inch rule), on forest land
Average annual other removals of sawtimber trees, in board feet (International 1/4-inch rule), on timberland
In addition the ratio estimate option (i.e. the option to choose a denominator) is returning incorrect estimates for any ratio involving net growth, mortality, or removals on timberland. Ratio estimates involving net growth, mortality, or removals on forest land are working correctly. Ratio estimates are intended to be restricted to timberland-to-timberland or forest land-to-forest land observations but the restriction is currently malfunctioning for timberland-to-timberland observations.
We are working to correct the problem and will update the alert when it has been corrected.
We are sorry for the inconvenience.
FIDO is working properly.
