MULTI-SOURCE NATIONAL FOREST INVENTORY (MS-NFI) 2021 RESULTS BY MUNICIPALITIES 
==============================================================================

1. The Files
------------

The excel-file contains descriptive sheet and forest resource tables for
the municipalities. The sheets can be exported, e.g., in .csv format in which
case the first column contains the municipality code (boundaries as on
1.1.2022). In some tables the cell values (mean, percentage) have more
decimals than the formatted values appearing in the sheets.
