There are many methods to estimate wild ungulate populations. One of these is represented by observations from vantage points usually employed in medium-low covered forest areas to estimate cervids. This method is subject to some limitations, such as the risk of double counting and the necessity to a high number of operators due to the small size of the observable areas. Such limitations could be reduced by integrating the “vantage points method” with Remote Piloted Aircraft System (R.P.A.S.) surveys.

Modern agriculture has increased food production, improved food security and reduced poverty, but farming has also caused a considerable decrease in biodiversity, primarily through land-use intensification and overexploitation, along with excessive pesticide and water use, nutrient loading and pollution. The major purpose of agriculture is to ensure sustainable food production, adequate nutrition and stable livelihoods for all.

Once the conditions that led to the creation of the Société Civile des Terres du Larzac (SCTL) have been introduced, the companion modelling approach used with this group of farmers is presented. The agent-based model co-constructed with a group of researchers and technicians is then described, as well as the way it was used to confront scenarios developed by the SCTL to envision management options of the forest massif, with scenarios developed by the farmers to improve the current functioning of their farms

The Spanish law Real Decreto 1469/2007 about the regulations of quality of Iberian pig meat, establishes limitations to the carrying capacity of Iberian pig in the dehesa (open oak parkland) and forces to the regional governments to make a programs of evaluation of acorn production at the beginning of each campaign, that will have to be based on agronomical, environmental, and topographical criteria, identifying each paddocks through SIGPAC.

The paper proves the necessity of making a system of technologies and machines for feed production as a necessary factor in the development of livestock breeding. The promising resource-saving technological groups include: radical improvement of natural forage lands; surface improvement of artificial hayfields and pastures and maintaining their productive service life with the use of combined machines; accelerated grassing of natural forage lands; and growing forage crops on the arable land.

Aunque el efecto del pastoreo en los ecosistemas ha sido ampliamente estudiado, muchos de los resultados a menudo resultan contradictorios. Esta ambigüedad es debida en parte a la capacidad de los herbívoros para dar forma a los sistemas naturales, favoreciendo a especies particulares de plantas o ejerciendo un efecto negativo o indiferente sobre otras.

Still, more agricultural land is getting abandoned in Slovenia, specially in less favored areas. Such process of degradation of fertile land is most intensively present in the Obalno-kraska region and Goriska. Similar happens with grassland in mountain region as less and less animals which are suitable for that region are bred there. To prevent brush encroachment and to start recultivation of aban

Farmland birds have suffered a severe decline in recent years throughout Europe including Ireland. Agricultural intensification is believed to be the main cause and this has led to the introduction of agri-environmental schemes, of which set-aside is a part. Bird abundance and diversity were compared between set-aside and adjacent tillage or grassland at 18 locations.

The classification of land usage in mountain grassland bovine areas is important for the management of forage production and grazing in grass-based livestock systems. The present paper proposes a novel, hierarchical neural network-based approach towards the classification of land usage in these areas. A survey of 72 farms was conducted in the Massif Central (France). Information was gathered on geographical characteristics and cutting and/or grazing practices on three general groups of fields: cut only, cut and grazed and grazed only fields.

The natural regeneration in the dehesa has been object of numerous studies, due to the ecologic and economic importance of such ecosystems. In this work is exposed a test of acorns germination of Quercus ilex L. subsp. ballota (Desf.) Samp, in the North of Córdoba (Spain), under three environmental conditions corresponding to the most traditional land uses of the dehesa: grazing, cereal sowing and fallow, each one with a different vegetal cover. A fourth group of acorns was placed in a tree nursery under controlled conditions.
