GRUEZMACHER, Mónica  e  DUIVENVOORDEN, Joost F.. GROWTH OF TRANSPLANTED TIMBER SPECIES SEEDLINGS IN THE SOUTH OF THE COLOMBIAN AMAZON: A PRELIMINARY STUDY. Colomb. for. [online]. 2008, vol.11, n.1, pp.35-43. ISSN 0120-0739.

Two commonly used timber species in the area of Amacayacu National Park (Quararibea sp. and Minquartia guianensis) were selected to develop an experiment that compared the early performance of seedlings in mature and old secondary forest. We transplanted seedlings of these species into mature and secondary forest plots and observed height and diameter increments as well as mortality for a period of approximately 70 days. In situ seedling performance under parent trees in mature forests was measured as a control. The structure of both experimentalforestswasnotapparentlydifferent.We found similar seedling performance for both species in the two forests. However, the seedlings hardly showed any relative height or relative diameter increment in the short period of measurements. The results show that enriching secondary forests by means of transplanting seedlings from timber species might be a promising way of ecological restoration.
