Temporihygrophilous Quercus broteroi forests in southern Portugal: analysis and...

This article deals with a phytosociological survey of marcescent Portuguese oak (Quercus broteroi) forests in southern Portugal, and presents the results of an analysis of 56 releve´s, combining Braun–Blanquet’s methodology with hierarchical cluster analysis (Ward’s Hierarchical Clustering, based on Bray–Curtis distance). From these results, a new temporihygrophilous Portuguese oak forest association is describ...

Guia geobotânico da excursão ao Parque Natural da Serra de Aires e Candeeiros

The “Serras de Aire e Candeeiros” Natural Park, in the Centre of Portugal, are mostly formed by limestone formations of the Middle Jurassic. Among the plant species located in this Protected Area, there are seven endemic species included in Annex II and/or IV of CEE/92/43 Directive by their rarity: Arabis sadina, Coincya cintrana, Iberis procumbens subsp. microcarpa, Juncus valvatus, Narcissus calcicola, Saxifr...

Geographic variation among iberian communities of the exotic halophyte Cotula c...

The exotic annual forb Cotula coronopifolia has locally invaded salt marsh communities naturally dominated by Spergularia marina along large parts of the Iberian coastline. While the floristic composition of C. coronopifolia dominated communities on the Atlantic coast of northern Portugal has already been described, this information was missing for the southern part of the country. We carried out a phytosociolo...

Flora e vegetação do sudoeste de Portugal continental

The present paper presents the updated syntaxonomical typology of southwest mainland Portugal, complemented with the table of correspondence of each syntaxon with the NATURA 2000 habitats code (when applicable) as well as the floristic catalog of the studied area. All the syntaxa include chorological, synecological and floristic information. Regarding the lower level syntaxa (association and subassociation), it...

Guia geobotânico da excursão ALFA 2009 ao litoral alentejano

The organization of the Geobotanical Excursion by ALFA (Associação Lusitana de Fitossociologia) is yet another contribution for the enhancement and addition of scientific knowledge regarding the flora and vegetation of the Portuguese territory. This field guide is, thus, a synthetic description of the flora and vegetation occurring in the Coastal Vincentine biogeographical district. Considering both the richnes...

The application of the Habitats Directive in Portugal

A succinct review of the application of the Habitats Directive in Portugal is presented. Since 1971 until 2000 Portugal has defined approximately 8,8% of its territory as national protected areas. With the application of the Habitats Directive nature conservation policies extended to more than 17,4 % of the territory increasing by 98% and the knowledge on vegetation community’s habitats was certainly deepened. ...

A methodological approach to potential vegetation modeling using GIS techniques...

An attempt to obtain a consistent spatial model of natural potential vegetation (NPV) for the mainland Portuguese territory is reported. Spatial modeling procedures performed in a Geographic Information System (GIS) environment, aimed to operationalize phytosociological expert-knowledge about the putative distribution of potential zona1 forest communities dominam in the Portuguese continental territories. The p...
