Exurban residential household behaviors and values: Influence of parcel size and neighbors on carbon storage potential

•Parcels >0.53ha (just over 1 acre) (LP) have proportionately less mown lawn.•LPs have more big trees, more trees planted, and less fertilization or irrigation.•LP owners are less concerned that their yard fits neighborhood norms.•Demographic variables alone do not account for differences in landscape behaviors.•Large exurban lots may provide more carbon storage than smaller lots.
