A method of monitoring the consequences of climate changes and status of environment on regional and global scales is presented. This approach supplements the dendrochronological method applied for historical monitoring of tree growth, which is reasonable and popular but has some restrictions. The subject of investigation was pine underwood (Pinus sylvestris L.), the monitored parameter was annual linear growth of trees (growth of trunk in height, branches in length). We called the proposed type of biometric investigations orpexometry ( is sprout in Greek); the corresponding element of the programme of monitoring is called orpexometric recording. An original procedure and results of its approbation in the Kandalaksha State Natural Preserve in 2000 and in the Pechora-Iluch State Natural Preserve in 2001 are presented, along with the algorithm of statistical processing of data, with the help of which a satisfactory accuracy of parameter estimation was obtained.
