The file present the data produced during long-term (three consecutive years 2019-2021) field observations and short-term girdling manipulation of top-crown shoots in three mature Betula pendula trees as details of our manuscript. Values of leaf gas-exchange, environmental variables, leaf water and nitrogen status, and concentrations of sucrose, hexoses (glucose and fructose), starch, total sugar, and total non-structural carbohydrate in leaves are listed. Data supporting "Seasonal dynamics and punctuated carbon sink reduction suggest photosynthetic capacity of boreal silver birch is reduced by the accumulation of hexose"dataset
