In this study we have analyzed the information
provided by 17 publicly available Eucalyptus
microsatellite (SSR) markers (Brondani et al.
1998, 2002; Jones et al. 2002; Steane et al.
2001) in the context of genetic identification
within a sample of 140 individuals from an elite
collection (denoted hereafter base) of RAIZ
genetic improvement population.
Portuguese forest area has a great expression being around 39%. Since the last centuries the Quercus suber L.(cork oak) areas have increased, reaching to 715 922 ha (23%) according to the last National forest inventory. Afforestation programmes financed by the European Union and the existing protection laws for the species are one of the main reasons for this increase. These efforts are important to promote for these stands a distribution by age class that ensure cork oak forest sustainability (only 14% of the existing even-aged stands are young stands with less than 10 years). In this study, the programme – Afforestation of Agricultural Land – in the region of Beira Interior Sul was analysed, to assess afforestation success during the period of 2001 to 2011.
In this study an agro-forestry area of cork oak partial affected by fire was considered. Even though having a forest management plan, the existing management compartments didn’t allow for a sustainable cork annual harvest. To achieve sustainability the area control method for forest regulation was first applied, using a cycle of nine years through a 27 years planning horizon. Later, cork annual yield was also considered in the forest regulation analysis. Cork yield was simulated along the 27 years period using the individual tree growth and yield model Suber. Finally, the proposed management unit compartments were produced as vector layer a GIS and the attribute table organized with all the information available in order to support forest management.
