Practice cost and size differences in invasive plant management strategies: An empirical analysis of US Great Plains states

•Practice cost and unit size differ by invasive plant management strategy and state.•Prescribed burning is less costly than brush management and mulching in the Great Plains.•Prescribed burning covers more area than brush management and mulching in the Great Plains.•Prescribed burning could be a cost-minimizing management strategy.•Expanding practice unit size of a small covering strategy could be a policy alternative.
