# §5040.4. What is the effect of designating sustained-yield units?


Designating new sustained-yield forest units abolishes previous O. and C. master unit or sustained-yield forest unit designations. Until new sustained-yield forest units are designated for the first time in accordance with [43 CFR part 5040](/cfr/43/part5040.md), the current master unit designations will continue to be in effect.
