Post hoc tests (such as Tukey's HSD or Bonferroni correction) are necessary in the event of a significant ANOVA because ANOVA only tells us that there is a significant difference in at least one group, but it doesn't tell us which groups are significantly different from each other. Post hoc tests allow us to make pairwise comparisons between all groups to determine which groups are significantly different from each other.
