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.

Previously reported issues with removals and mortality in EVALIDator have been corrected.

FIDO is working properly.
