Joined and flat version of EDI data package knb-lter-hfr.118.33

Source: R/data.R

A fully joined and flat version of EDI data package knb-lter-hfr.118.33 (Ant Assemblages in Hemlock Removal Experiment at Harvard Forest since 2003) with all relevant ecocomDP L1 identifiers and content added. Use this dataset as an input to the L0_flat argument of the "create" functions.
