“…5.1) confirm the change over time in the presence of Abies alba and provide new data about the chronology of its dynamics (Pèlachs et al 2009b;Bal et al 2011;Pérez-Obiol et al 2012;Cunill et al 2013). In addition, other techniques of high spatial precision such as soil charcoal analysis or sedimentary macroremains analysis have confirmed this chronology and provided more information about the altitudinal and local distribution.…”

“…At that time, the species would have achieved a dominant presence in the montane zones and low-altitude areas (Schneider and Tobolski 1985;Tinner et al 1999;Wick and Möhl 2006). In the Pyrenees, environmental geohistory studies have confirmed this trend (Jalut 1988;Pèlachs et al 2009b;Galop et al 2013;Cunill et al 2015). A study by Cunill et al (2015) in fir populations at 300 m altitude on the north slope of the Pyrenees showed that, far from being anomalies or the fruits of repopulation efforts, these arboreal masses are witness to the greater importance of firs in the past in low pre-Pyrenees zones and a presence in the area for at least 5000 years.…”

“…During the late glacial periods, Abies alba withdrew to refuge zones (still little-known to this day) and then at the beginning of the Holocene migrated progressively from east to west along the Pyrenees range. It appears earlier in the Mediterranean Pyrenees (in Estanilles about 8500 years cal BP, in the Burg Lake about 8000 years cal BP), and later in the Bassa Nera of the Atlantic-influenced Aran Valley (at about 6500 years cal BP) (Jalut et al 1998;Esteban et al 2003;Pèlachs et al 2009b). In coming years, recently initiated pollen and genetic studies should begin to provide more information on this topic (Sancho-Knapik et al 2014;Matías et al 2016).…”

Proper management of the perceived value of any geographic space requires the capacity to interpret research results from spatial, temporal, and environmental points of view, applying the principles of environmental geohistory. Basic concepts such as baseline, threshold, or resilience are discussed from a long-term ecological perspective, with examples that explain the dynamics of fir forests as well as the changes in agricultural cover. Studying the changes in the altitudinal limit of the forest and surveying the wetlands dynamics on the southern slopes of the central Catalan Pyrenees have been shown to be effective tools to develop appropriate management tasks. The arguments presented are useful to enrich the public debate over management policies for natural protected spaces in high-mountain areas.

“…Generally, a decline of silver fir has been going on in Europe for the last two centuries (Musil 2003;Šindelá and Frýdl 2004;Kuneš et al 2005;Abraham 2006;Zerbe 2002;Diaci 2002;Mosandl and Kleinert 1998;Kuiters and Slim 2002;Pèlachs et al 2009). In typical fir regions of the Balkan Peninsula, this trend has been mostly attributed to the effects of past air pollution and, more recently, to the increasing negative impact of game (e.g.…”

Introduction of silver fir (Abies alba Mill.) as one of the historically important coniferous tree species in Central Europe into allochthonous cultivated forests is an important task for contemporary and future generations of foresters. The aim of our work was to optimize the management of fir in allochthonous cultivated stands of National Park Ceské Švýcarsko formed mainly by Norway spruce (Picea abies /L./Karst.). The effects of light and soil conditions and game on the survival and growth of fir plantations were investigated. Browsing was determined as the limiting factor for fir reintroduction. Assessing the significance of edaphic conditions for the height increment of fir, favourable effect of luvisol could be demonstrated as compared to acidic soil. Canopy openness maximum of 30% and stand basal area of 30 to 43m 2 /ha with relative direct radiation of up to 45% and relative indirect radiation of up to 55% with prevalence of the diffuse component create optimal environmental conditions for the survival and sustainable growth of fir plantations in the spruce stand in regeneration.

“…as well as for scientific research (landscape analysists, macroecologists, etc.). Vegetation and land cover dynamics have a key role in landscape structure; indeed, changes in the distribution of plant communities or human alteration of biotic and abiotic components are main drivers of landscape evolution (Cowen and Jensen 1998;Serra, Pons, and Sauri 1999;Pèlachs et al 2009;Sexton et al 2013b). Furthermore, analysis of land cover changes allows researchers to understand the interactions between ecological and climatic systems (Bonan 2008;Herrera and Doblas-Miranda 2012;Xian, Homer, and Aldridge 2012;Beltrán et al 2014).…”

Global or regional land cover change on a decadal time scale can be studied at a high level of detail using the availability of remote sensing data such as that provided by Landsat. However, there are three main technical challenges in this goal. First, the generation of land cover maps without reference data is problematic (backdating). Second, it is important to maintain high accuracies in land cover change map products, requiring a reasonably rich legend within each map. Third, a high level of automation is necessary to aid the management of large volumes of data. This paper describes a robust methodology for processing time series of satellite data over large spatial areas. The methodology includes a retrospective analysis used for the generation of training and test data for historical periods lacking reference information. This methodology was developed in the context of research on global change in the Iberian Peninsula. In this study we selected two scenes covering geographic regions that are representative of the Iberian Peninsula. For each scene, we present the results of two classifications (1985-1989 and 2000-2004 quinquennia), each with a legend of 13 categories. An overall accuracy of over 92% was obtained for all 4 maps.
