Short summary
Our study investigated the effect of coniferous and deciduous vegetation on Hg cycling. We quantified Hg in aboveground vegetation and soil horizons at eight paired forest sites. Organic horizons at coniferous stands had greater Hg concentrations and pools than deciduous stands. Mineral soil Hg pools did not vary with vegetation type but varied with soil chemical properties. Estimated Hg litterfall flux was greater at deciduous stands. A shift in vegetation type may impact Hg accumulation.
