A species level classification of maquis would be useful in understanding vegetation structure and dynamics, which would be an indicator of degradation or succession in the region. Although remote sensing was regularly used for classification in the region, maquis are simply represented as one to three categories based on density or height. To fill this gap, we test the capability of Sentinel-2 imagery, together with selected ancillary variables, for an accurate mapping of the dominant maquis formations. We applied Recursive Feature Selection procedure and used a Random Forest classifier. The algorithm is tested using ground truth collected from site and reached 78% and 93% overall accuracy at species level and physiognomic level, respectively. Our results suggest species level characterization of dominant maquis is possible with Sentinel-2 spatial resolution.

[Termes IGN] zone sinistréeRésumé : (Auteur) Context : In the Mediterranean area, different post-fire management strategies are used for coppices of resprouting species to promote a more regular forest structure, enhance plant growth, and reduce fire risk. However, the effects of these management treatments on forest-associated fauna are unknown, which in turn could be limiting their beneficial effects.
Aims : The aim of this work was to determine whether forest management of a recently burned area dominated by a vigorous resprouting tree species (Arbutus unedo L.) affects ant communities.
Methods : Ant communities, sampled using pitfall traps, were examined from unmanaged and selective thinning coppices of A. unedo. Ants are here used as bioindicators of ecosystem health and surrogates for other animal groups.
Results : Very limited effects of these post-fire management strategies on the structure and composition of ant communities were found. The lack of effects could be due to the reported small changes in physical conditions among treatments; or either, the most sensitive ant species to these post-fire management treatments might be the same ones affected by fire and, consequently, the ant species that would potentially be affected most were no longer in the study area.
Conclusion : The lack of any significant effects caused by these post-fire management practices on the associated fauna of A. unedo coppices points out the suitability of these treatments in these circumstances.Numéro de notice : A2014-580 Affiliation des auteurs : non IGN Thématique : FORET Nature : Article DOI : 10.1007/s13595-014-0381-5 Date de publication en ligne : 05/06/2014 En ligne : https://doi.org/10.1007/s13595-014-0381-5 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=74770

[Vedettes matières IGN] Ecologie forestièreRésumé : (auteur) The authors characterize the main preforest and forest formations in the Western Mediterranean where laurifolious species are present. They successively envisage the distribution of these elements in sclerophyllous, deciduous and high altitude coniferous forests to demonstrate that laurifolious species are undeniably at their peak development in deciduous oak forests. From their work it appears that the best preserved structures have undergone either a rational silvicultural management for a very long lime, or have been spared from intensive human activity (mountain peaks in Algeria and Morocco, sites at cliff bases in France). The actual distribution of these elements makes apparent the existence of four groups, two of which have a high bioclimatic value:
— the thermo-Mediterranean group with deciduous oaks and Laurus nobilis;
— the upper Mediterranean group, the supra-Mediterranean with deciduous oak forests, fir forests and cedar forests and the mountain Mediterranean group with yew and holly;
— the Macaronisian laurifolious species group with Laurus azorkas and Prunus lusitanica;
— the fourth group includes structures directly conditioned by human degradation (Viburnum tinus and Arbutus unedo shrublands, Buxus sempervirens and Buxus balearica shrublands).
Historic factors provide concurring results and lead to the conclusion of a probable extension of these elements towards the Atlantic within deciduous oak forests during climatic phases more humid than these found today.Numéro de notice : A1994-028 Affiliation des auteurs : non IGN Thématique : FORET Nature : Article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=82211
