An estimation of Scots pine (Pinus sylvestris L.) ecosystem productivity on reclaimed post-mining sites in Poland (central Europe) using of allometric equations

Abstract

The work presents determination of the productivity of post-mining ecosystems (PME) derived from the aboveground biomass and annual biomass increment of Scots pine (Pinus sylvestris L.) stands. Single tree biomass assessment data from 42 cut trees were used in developing local allometric equations which may be used as an index during post-mining reforestation projects. The total biomass of pine ecosystems was determined from dendrometric measurements of sample plots with the use of elaborated equations. Forest floor vegetation was determined using the harvest method. Control plots were set up in the vicinity of the mining-sites at a managed forest on natural pine sites (NPS). Results confirm wide ecological amplitude of pine and indicate a high PME productivity on all substrates (2.79–4.34Mgha−1yr−1).
