THE STATE OF VEGETATION IN THE STANDS ESTABLISHED ON DEGRADATED LANDU IN THE HILLY AREA OF TRANSILVANIA

In the past, Transylvania was an area of high afforestation, in 1919 having a surface of about four million hectares. Due to the need to expand agricultural areas, accessible ones have been deforested, with some of them degrading as a result of intense and irrational grazing. In order to ensure that the degraded areas are not totally unproductive, in the 1970s, they have been afforested, many of them being made with resinous, even in situations where the ecological group provided for other solutions. A number of six sample surfaces were taken into study, in which measurements were taken to track the growth of stands on degraded lands. These stands suffer from isolated windfall and crown breaks, due to the fact that the silvicultural operations are performed at a lower frequency than the production stands. Comparing the data obtained, it was found that the most healthy stands are in the Săvădisla, Sic and Sărmaşu areas, while in the Filitelnic area the trees are affected by isolated windfall and tops and crowns breaks. For tree damage to occur at the lowest possible frequency, strict silvicultural operations required for each stage of development is necessary
