Data on the volume of the current and general attrition at the constant experimental plats in spruce stands in the forestry’s during 2004–2013 are analysed. According to the forestry’s and the results of own inspections of the constant experimental plats, the comparative analysis of the spruce stands state on constant experimental plats of Tolochin forestry, Cherven forestry, Chausy forestry and Borisov skilled forestry is made. As a result dynamics of state changes in spruce stands at the experimental plats for 2011–2014 and dynamics of dead wood formation in spruce stands is presented. The current as-sessment of the constant experimental plats condition on the average category of state and according to the current and general attrition is also given. The reasons of difference between our and forestry data on the assessment of a condition of spruce stands on constant trial squares are analysed and discussed.
It is established that in a number of the surveyed constant experimental plats of the forestry’s there is an overestimate of an assessment of a condition of spruce forest stands that can lead to an inexact assessment of current state of spruce plantings in a number of regions of the republic
