A vegetation assessing apparatus (101) obtains step count measurement results obtained by a step measuring device (102) attached to a livestock animal (A) pastured in a pasture (H). The vegetation assessing apparatus (101) assesses whether a state of vegetation of the pasture (H) is a state suitable for pasturing, based on temporal change of the step count measurements obtained by the step measuring device (102). The vegetation assessing apparatus (101) transmits an obtained assessment result to a portable communications terminal (103) used by a livestock raiser.
