The aim of the work was to evaluate the condition of trees planting along the main road S7 in central Poland. There are many examples that trees along roads and highways in Poland grows badly and mortality of plants within one or two years after planting is on a very high level. This caused great losses of public means and huge, non-valuated losses for the environment and countryside. Results of this study where the evaluation of trees planting along road S7 between Jedlińsk and Grójec was undertaken, shows that almost 50% of trees died or vanished within 2-3 years after planting. Total number of trees planted on the studied area (8 species) was about 1775 units, and 887 out of them are lost. This made losses on 134000 PLN only on this segment of road. Value of trees planted along S7 road between Jedlińsk and Grójec was calculated on 287000 PLN, the coast of trees consisted on 169000 PLN.
