Study Site • Gaelic name: Mòine meaning mossy or boggy and Mhór meaning great or large • Plateau area 4 x 4 km at 950 m elevation • Sub-arctic plateau: late autumn to spring often snow covered

Snow cornicing on Caochan Dubh (Jan, 2015) Study site highlighting where hydrological monitoring is carried out

Research Aims • Define extent and condition of the site • Quantify aquatic carbon loss • Quantify impact of deer activity

Methods • Nested catchment approach

Future work • Calculate aquatic C budget for site • Are there any differences between the streams?

• Determine impact deer are having on site before they are excluded from an area

Conclusions • Help inform future restoration work • Habitat worthy of research and protection • A role to play in addressing climate change
