Afforestation represents a viable solution for the ecological reconstruction of degraded lands, creating medium and long-term premises for using and sustainably developing these lands. The usage of fast-growing woody species in the afforestation of degraded lands include many advantages. The present paper presents data regarding the actual state, biometrics and auxological characteristics, as well as the productive potential of stands from fast-growing species (locust, alders, poplars and willows) from different conditions of degraded lands. Locust (Robinia pseudacacia L.) is one of the fast-growing forest species utilised on degraded lands in Romania. In addition, the species has a recognized importance at a high international level both through its bioproductive potential as well as through its ecological plasticity. All the species that were analysed had a good behviour in relation with the environmental conditions of degraded lands, both from a growing perspective and a health state one. However, this situation is present up to the age of 25-30 years. After this age, stand dryness, thinning, and a decrese of tree growth and quality are affecting the stand’s natural regeneration capacity and ecological diversity.
