User Alert:

January 4, 2017: FIDO is not able to be accessed from outside the Forest Service at this time due to security configuration files. We are working with the Chief Information Office to resolve the issue.

October 20, 2016: New Tool Available! The Design and Analysis Toolkit for Inventory and Monitoring, DATIM, is available.

January 8, 2016: FIDO's Standard Reports is no longer being maintained. If you are experiencing issues, please use the custom reporting tool instead. FIDO's Standard Report option will be discontinued upon future release.

For FIDO, EVALIDator and the DataMart users wishing to know what has recently become available see this page:

September 22, 2015: The EVALIDator is unable to produce estimates of growth, removals and mortality for multiple inventories when "Trend analysis" is chosen as the row classification variable and the inventories chosen have different sampling designs (i.e., a mix of periodic and annual inventories). In the event that a user inadvertently runs such a retrieval the EVALIDator will return zeroes for the periodic inventories and the correct numbers for the annual inventories. We are sorry for any inconvenience.

The Design and Analysis Toolkit for Inventory and Monitoring (DATIM) is a collaboration between the National Forest System (NFS), Forest Service Research & Development (FS R&D), and Ecosystem Management Coordination (EMC). DATIM provides four modules: an analysis tool for inventory and monitoring (ATIM) used for creating tables; a spatial intersection tool (SIT), a design tool for inventory and monitoring plans (DTIM), and a data compilation system (DCS) to add FVS attributes to DATIM datasets.



This program allows users to produce a large variety of population estimates and their sampling errors based on the current FIADB.
