Acorn & mast crop
Iowa's hardwood timber — particularly the Driftless region in the northeast — supports productive white oak, red oak, and bur oak stands. Mast quality in these scattered timber pockets shapes how hunters compete for the state's premier trophy zones.
Multi-year trend
Categorical ratings per year. Overall is solid; white oak and red oak series are dashed.

Annual mast report
2025
White oak
Red oak
Other mast
Regional notes
Preliminary reports show productive statewide mast.
Hunter implication
Mast is plentiful enough to pull deer off plots and ag fields. Find the productive oaks and set up tight; expect deer to be less predictable on traditional stand sites built for travel routes.
Annual mast report
2024
White oak
Red oak
Other mast
Regional notes
Solid recovery and bumper white oak in some Driftless counties.
Hunter implication
Mast is plentiful enough to pull deer off plots and ag fields. Find the productive oaks and set up tight; expect deer to be less predictable on traditional stand sites built for travel routes.
Annual mast report
2023
White oak
Red oak
Other mast
Regional notes
Mixed conditions; mast more variable than typical.
Hunter implication
Mixed conditions — some areas with productive oaks, others without. Scout for the pockets that produced and hunt the travel routes between bedding and mast. Plots and ag fields still hold deer where mast failed.
Annual mast report
2022
White oak
Red oak
Other mast
Regional notes
Strong Driftless production; western timber average.
Hunter implication
Mast is plentiful enough to pull deer off plots and ag fields. Find the productive oaks and set up tight; expect deer to be less predictable on traditional stand sites built for travel routes.
Hunter strategy
Locate specific white oak flats with active drop, hunt tight to the trees, and expect deer to be less predictable on traditional travel-corridor stand sites. With food everywhere, generic stand placement loses to oak-specific scouting.
Always cross-reference with the most current published agency report before basing planning decisions on this page.
State-wide mast surveys are a starting point. Bield: Hunt lets you pin the specific oaks producing on your property, track drop year over year, and find the stands those trees pull deer to.
