Abstract. Cellulose content (CC [%]) in tree rings is usually utilized as a tool to control the quality of the α-cellulose extraction from tree-rings in the preparation of stable isotope analysis in wooden tissues. Reported amounts of CC [%] are often limited to mean values per tree. For the first time, CC [%] series from two high Alpine species, Larix decidua Mill. (European Larch, LADE) and Pinus cembra L. (Swiss stone pine, PICE) are investigated in modern wood samples and Holocene wood remains from the Early and Mid-Holocene. Modern CC [%] series reveal a species-specific low-frequency trend independent from their sampling site over the past 150 years. Climate-cellulose relationships illustrate the ability of CC [%] to record temperature in both species, but for slightly different periods within the growing season.

The Holocene CC [%] series illustrate diverging low-frequency trends in both species, independent of sampling site characteristics (latitude, longitude and elevation). Moreover, potential age trends are not apparent in the two coniferous species. The arithmetic mean of CC [%] series in the Early and Mid-Holocene indicate low CC [%] succeeding cold events. In conclusion, CC [%] in tree rings show high potential to be established as novel supplementary proxy in dendroclimatology.

Short summary
Cellulose content (CC [%]) series from two high Alpine species, Larix decidua Mill. (European Larch, LADE) and Pinus cembra L. (Swiss stone pine, PICE) are investigated in modern wood samples and Holocene wood remains from the Early and Mid-Holocene. Trends in modern and Holocene time series, as well as climate-cellulose relationships for modern trees in the Alps show high potential for CC [%] to be established as novel supplementary proxy in dendroclimatology.
