Method for evaluation of coarse cork oak root system by means of digital imaging
Surový, Peter; Ribeiro, Nuno Almeida; Brasil, Felipe; Pereira, João Santos; Oliveira, Maria do Rosário GamitoDigital imaging is becoming a powerful tool for data storage and information retrieval. Image comparison and similarity evaluation has become part of the information market and it is today a common part of, for example, web search engines. The cork oak tree (Quercus suber L.), the dominant species of the ‘montado’ woodland system is, due to its cultural and socio-economic value, protected by law that prevents e...
Growth modeling in complex forest systems: CORKFITS a tree spatial growth model...
Ribeiro, Nuno Almeida; Surový, PeterCork oak (Quercus suber L.) woodlands (montado) consist of a multifunctional forest system that covers about 713,000 ha in Portugal. Today, its importance stems from cork production, with Portugal producing half of the cork in the world. As the main economic objectives may change with changes in markets and environment conservation concerns (e.g. biodiversity, water, carbon) there is a need for improved managem...
Software development for forest growth models and management. CORKFITS: web bas...
Surový, Peter; Vones, Petr; Ribeiro, Nuno AlmeidaNew methods of forest management and the study of their impact on sustainability are strongly dependent on realistic mathematical modelling. The complexity of the models however, makes the use of computational power, and thus the incorporation of knowledge from computer science and research, indispensable. In this paper we wish to demonstrate the development of a simulator for the growth and production of cork ...
Observations on 3-dimensional crown growth of Stone pine
Surový, Peter; Ribeiro, Nuno Almeida; Pereira, João SantosIn this work we wish to demonstrate the possibility of a reconstruction of the 3D growth of the Stone pine (Pinus pinea L) crown. The crowns of two samples were digitized in segments corresponding with individual years, which allowed us to reconstruct length-growth and 3D shape over the last 5 years. Due to the low sample amount, we limited ourselves to observations and methodology-descriptions instead of overa...
Economic implications of different cork oak forest management systems
Pinheiro, António Cipriano; Ribeiro, Nuno Almeida; Surový, Peter; Gonçalves, AlfredoThe agro-silvopastoral system “montado” dominates the landscape of the south-western Iberian Peninsula, occupies approximately 3.1 million hectares of woodland in Spain and 1.2 million hectares in Portugal. The forest system “montado” is mostly dominated by Mediterranean evergreen oaks such as cork oak (Quercus suber L.) and holm oak (Quercus rotundifolia). The “montado” production system management aims the ma...
