Adaptive Management on Sustainability of Cork Oak Woodlands
نویسنده
چکیده
The cork oak woodland production systems result from the integration of conflicting activities in the same space creating the need of constant search of equilibrium between its components in order to achieve sustainability. In a climate change environment, associated with recent modifications in rural societies, adaptive management concepts are needed so as to maintain cork oak woodland systems sustainable. Nowadays/Currently cork oak woodlands are facing disturbances that are affecting the production system sustainability both by intensification of the activities undercoverthat leads to a lack of regeneration and consequent disappearing of the crown cover, loss of cork production and site degradation mainly by soil loss-, or by the abandonment that conducts to an invasion of shrubs and other oaks increasing the competition (reducing cork production) and the risk of forest fire. Only adaptive management techniques associated with growth models and decision support systems, constructed in knowledge based monitoring system, are able to prevent cork wood land decline with the adoption of management practices focused in long term objectives. For the present study it was selected a set of permanent plots according with site quality and stand age and structure. Simulation studies results indicates that cork oak woodland system sustainability (both economical and ecological) is supported in regeneration events associated with the shrub control techniques without soil mobilization with strong dependency of cork prices and

Drivers of Productivity Trends in Cork Oak Woodlands over the Last 15 Years
Higher biodiversity leads to more productive ecosystems which, in turn, supports more biodiversity. Ongoing global changes affect ecosystem productivity and, therefore, are expected to affect productivity-biodiversity relationships. However, the magnitude of these relationships may be affected by baseline biodiversity and its lifeforms. Cork oak (Quercus suber) woodlands are a highly biodiverse...
متن کاملThe Way Forward
Cork oak trees and woodlands have been managed and cherished by generations of people of many different Mediterranean cultures and in many different ways. Their resilience in a sometimes hostile environment, their economic importance, and their nonmonetary, or nonmarket, aesthetic and cultural values make these cultural woodland systems an outstanding example of the kind of mutually beneficial ...
متن کاملA Comparison of Management Strategies in the Oak Woodlands of Spain and California
The characteristics, uses, and management of oak woodlands and savannas in California and southern Spain are compared. There are many similarities between the Spanish dehesa and the California oak woodland. Both are located in Mediterranean climate zones, and are used predominantly for livestock grazing. However the Spanish dehesa is a more diverse and long-standing system of management. Produc...
متن کاملEconomic implications of different cork oak forest management systems
The agro-silvopastoral 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 maintenance of a balanced sustainable land use to cope with the Mediterranean climate variability. One important issue in cork oak forests is the control shrub growth in order to ...
متن کاملEnvironmental and microbial factors influencing methane and nitrous oxide fluxes in Mediterranean cork oak woodlands: trees make a difference
Cork oak woodlands (montado) are agroforestry systems distributed all over the Mediterranean basin with a very important social, economic and ecological value. A generalized cork oak decline has been occurring in the last decades jeopardizing its future sustainability. It is unknown how loss of tree cover affects microbial processes that are consuming greenhouse gases in the montado ecosystem. ...
