Terceira Island (area:400.6km²; elevation:1,021.14m) is one of the nine islands from the Azores archipelago, located in the North Atlantic, roughly at 38°43′49″N, 27°19′10″W. The climate in the Azores is temperate oceanic, with regular and abundant rainfall, with high levels of relative humidity and persistent winds, mainly during the winter and autumn seasons. Terceira Island is known for the presence of some very important pristine areas at high elevation (Gaspar et al. 2011). However, few natural areas still remain at lower elevations, notably in Praia da Vitória’s council. Three wet areas, Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP) were studied in this project. Coastal vegetation dominates, namely Juncus acutus, and still includes some arboreal cover by the native shrub Morella faya. The Erica-Morella coastal woodlands as described in Elias et al. 2016, are not present and the exotic invasive species Arundo donax is very common. The PPV was a large coastal salty marshland with associated dunes, which was largely transformed and reduced for urban development and underwent several dynamic changes in the last 500 years of human occupation. After some major work performed between 2006 and 2010, PPV is currently characterized by a large waterbody with islands of Juncus acutus isolated by channels. PBJ was originally one of the largest dune areas from the Azores, but after the construction of the Praia da Vitória Harbor, it was reduced to a very small wet area with a dune covered partially by J. acutus. Of particular relevance is the presence of a small stream adding some diversity of vegetation and arthropods. The case of PPCP is completely different, since this is a recently created wetland, resulting from the removal of large amounts of stones for the construction of the Praia da Vitória harbor, around 1980. As a consequence a new ecosystem was created, the quarry of Cabo da Praia.

The inventory was conducted during the years of 2013, 2016 and 2017 under the responsibility of Rosalina Gabriel with the participation of Javier Diaz Castillo, César Pimentel and Mariana Reis Brito. The distribution of sampling dates and collectors by the three sites. Species identification were performed by César Pimentel, under the supervision of Rosalina Gabriel and David Claro, under the supervision of Cecília Sérgio. The identification of some challenging samples was performed by Manuela Sim-Sim and Cecília Sérgio.
|Title||The inventory of bryophytes in three coastal wetlands from Terceira Island (Azores)|

|Study Area Description||Terceira Island (area: 400.6 km2; elevation: 1,021.14 m) is one of the nine islands of the Azores archipelago, located in the North Atlantic, roughly at 38°43′49′′N 27°19′10′′W. The climate in the Azores is temperate oceanic, with regular and abundant rainfall, high levels of relative humidity and persistent western winds, mainly during the winter and autumn seasons. Terceira Island is known for the presence of some very important pristine areas at high elevation (Gabriel and Bates 2005 ). However, few natural areas still remain at lower elevations, notably in Praia da Vitória county. Three wetland areas, Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP) were studied in this project. Coastal vegetation dominates, namely Juncus acutus and still includes some arboreal cover by the native shrub Morella faya. The Erica-Morella coastal woodlands as described in Elias et al. 2016 are not present and the exotic invasive species Arundo donax is very common.|
|Design Description||A network of three or four transects in each wetland (160 m x 2 m or 300 m x 2m), was sampled every 20 m, in sampling points (4 m ); each sampling point was searched for bryophytes, collecting a maximum of six samples/microplots (10 cm x 5 cm); three replicates from soil and three replicates from rock.|
The personnel involved in the project:
In each site, bryophytes were sampled during the summers of 2013, 2016 and 2017 using a combination of standardised methods that included, in each transect and at every 20 metres, an area delimited of 4m2. Each sampling point (quadrat) was carefully examined to collect three samples (replicates or microplots) for each of the substrates that could be colonized by bryophytes (soil, rock). The area collected in each replica (microplot) was 50 cm (10 cm x 5 cm). The maximum number of samples obtained per sampling point was six (three replicates of soil and three of rock), but many sampling points did not contain bryophytes, especially those that were placed in places periodically flooded with brackish waters. For each sample of 10 cm x 5 cm, the scales for the ecological variables were adapted from Gabriel and Bates 2005.
|Study Extent||This study covers a small coastal area with 3.58 km extension between PPV and PPCP.|
|Quality Control||The correct identification of the sampled taxa is crucial. Keys and floras were used to identify the species, and their coverage (in %) was also estimated for each microplot. The main floras used were Smith 2004, Casas et al. 2006 for mosses and Paton 1999, Casas et al. 2009 for liverworts. Taxonomic keys provided by Schumacker and Váňa 2005 and field guides ( Atherton et al. 2010 , Llimona et al. 2004 ) were also consulted. Some important internet databases were also consulted, namely the Azorean Biodiversity Portal and TROPICOS to obtain taxonomic data and BBS Field Guide online pages, Bildatlas der Moose Deutschlands and Swissbryophytes to obtain morphological and ecological data. Nomenclature follows Gabriel et al. 2010 . The colleagues Michele Aleffi (University of Camerino, Italy), Juana Maria González Mancebo (Universidade de La Laguna, spain) and Maria Manuela Pinheiro Sim-Sim (University of Lisbon) revised samples belonging to Grimmia, Didymodon and Cephaloziella. Accumulation curves were performed and completeness was high for all sites when using the Jackknife first order estimator with values higher or equal to 74%.|
