Abstract: After the catastrophic fire of 2007 in Parnitha mountain, reforestation has taken place with greek fir (Abies cephalonica) in surfaces of the burned fir forest in the National Park. To assist the regeneration of fir, which under natural conditions depends on nurse plants for successful establishment, several sites were planted with black pine (Pinus nigra). In the present study the development of this aspect of the reforestation project is investigated in five monitoring plots which were planted in 2009 and 2010. Black pine seedlings were surveyed in November 2011. Results show that black pine seedlings exhibit low survival rates. The differences among plots were statistically significant. Various other problems were also observed, such as browsed, broken or dead seedling top and dead needle occurrence. The average apical growth of seedlings was lower than in the growth period of 2010. Also in this case, there is a statistically significant difference of the median apical growth among plots.
