Companhia das Lezírias is one of the six research and monitoring stations of LTER-Montado, an umbrella site located in the Alentejo province in south Portugal (southwestern Iberia). The "Montado" represents an unique agro-silvo-pastoral ecosystem (named "dehesa" in Spain) found only in the Mediterranean basin. These savannah-like landscapes are dominated by evergreen cork and/or holm oaks and were shaped over millennia of traditional land use practices. These multi-use forests are two-layered systems that combine, in a single space, forest harvesting, extensive livestock husbandry, pastures and/or cereal cultivation (the most evident economical revenues), with other traditional uses (hunting, beekeeping and mushroom picking). Recently, increasing awareness arose on their benefits as biodiversity reservoirs, recreation grounds, and other ecosystem services providers, but these non-productive functions are not equally perceived and valued by users, as they tend to be conflicting with productive ones. Companhia das Lezírias is a state-run property, located in the bank tributary of the Tagus River, in the Ribatejo province, 30 km northeast Lisbon and 7 km from Vila Franca de Xira.Cork oak (Quercus suber) is the dominant tree type, with an average of 68 adult trees per hectare.Cork oak stands are the major use and the priority in terms of land management. It covers 6.751 ha (78% of forested land). Pine and eucalyptus stands (1.900 ha), agriculture areas, pastures and dams complete the current use of soil. Some tree decline is observed, especially on podzols. The natural regeneration of the tree stand is not uniform, and it is lacking in some places because of grazing and shrub clearing for fire prevention. No fires have been reported in the last 20 years. Conflicting interests arise from the livestock grazing component that affects the natural regeneration of cork oak trees. Interventions and adjustments to promote natural regeneration and active afforestation (e.g. fencing combined with shrub clearing) have been included in the stakeholder´s management plan over the last years.

Herdade da Coitadinha is one of the six research and monitoring stations of LTER-Montado, an umbrella site located in the Alentejo province in south Portugal (southwestern Iberia).

Recently, increasing awareness arose on their benefits as biodiversity reservoirs, recreation grounds, and other ecosystem services providers, but these non-productive functions are not equally perceived and valued by users, as they tend to be conflicting with productive ones. Herdade da Coitadinha is a state-run property, located in the bank tributary of the Guadiana River, in the Alentejo province, 200 km south-east Lisbon and 8 km from Barrancos (38º10’32’’N – 7º02’22’’W). Holm oak (Quercus ilex) is the dominant tree type. The site was bought by EDIA as a biodiversity offset to the building of the Alqueva dam, and so it is currently managed as a nature protection area (Parque Natureza de Noudar; www.parquenoudar.com). Management is made to promote biodiversity, while demonstrating the compatibility with land uses such as cattle grazing (0.5 livestock units/ha), winter fattening of black pigs, hunting (mostly wild boar), and eco-tourism. Holm oak woodlands are managed to promote natural regeneration, increase acorn production and maintaining tree health. In the foreseeable future the site will maintain its current land use, and so there are no imminent threats to the montado system. The main problem is the spread of oak tree diseases and mortality, which in the mid-term may impair the health of the ecosystem. Fire is a permanent threat, but there is thorough fire surveillance during the periods of high risk.

Herdade da Ribeira Abaixo is one of the six research and monitoring stations of LTER-Montado, an umbrella site located in the Alentejo province in south Portugal (southwestern Iberia). The "Montado" represents an unique agro-silvo-pastoral ecosystem (named "dehesa" in Spain) found only in the Mediterranean basin.

Recently, increasing awareness arose on their benefits as biodiversity reservoirs, recreation grounds, and other ecosystem services providers, but these non-productive functions are not equally perceived and valued by users, as they tend to be conflicting with productive ones. Herdade da Ribeira Abaixo is a state property, located on the left bank of Sado River, in Baixo Alentejo province, 100 km south of Lisbon and 7 km from Grândola (38.06° N – 8.35°W). Cork oak (Quercus suber) is the dominant tree type, with an average of 43 adult trees per hectare. Since 1990, there is a single main economic output - cork, which is harvested in a 9-year cycle, with an average production of 450 kg (dry weight) per hectare per year. Since 1998, cattle herding was abandoned and substituted by sheep, with an average stocking of 0.1 animals per hectare. Recently (2003 and 2004) the property was subject to management actions aiming to foster the natural regeneration of cork oaks; cork oak saplings were also planted in a recently burned area. The shrub layer is cleared heterogeneously across the property every 4-5 years. A serious tree decline is observed, especially in the high plateaus. Natural regeneration is not uniform, being concentrated in north facing slopes with a dense shrub layer. Ovine grazing, though of low intensity, is partly responsible for lack of regeneration. Holm oaks are rare in the property, but are increasing. Parts of the property were burnt repeatedly (the more recent fires happened in 2001 and 2003); however some of the north facing slopes maintain a luxurious mixed oak forest and were not burnt in the last 30 years. In these areas, shrub cover and height are increasing.

Machuqueira do Grou is a state-run property, located Bank tributary of the Tagus River, in the Ribatejo province, 100 km northeast Lisbon and 25 km from Coruche (39.116° N – 8.352°W). Cork oak (Quercus suber) is the dominant tree type, with an average of 90 adult trees per hectare. Managed as an agro-silvo-pastoral system but most of the woodland has been managed so as to maintain or increase tree crown cover over the last 10 years. Some tree decline is observed, especially on podzols. The natural regeneration of the tree stand is not uniform, and they are lacking in some places because of grazing and shrub clearing for fire prevention. No fires have been reported in the last 100 years. Conflicting interests arise from the livestock grazing component that affects the natural regeneration of cork oak trees. Interventions and adjustments to promote natural regeneration and active afforestation (e.g. fencing combined with shrub clearing) have been included in the stakeholder´s management plan over the last 5 years.
