“…Pico Island is divided into three municipalities: Madalena, São Roque do Pico and Lajes do Pico, with a population density of approximately 31.8 inhabitants/km 2 in 2011 (PORDATA 2015). The economy is currently dependent mainly on crops, cattle production, fisheries and tourism (Calado et al 2014). Settlements, transportation infrastructure and economic activities are concentrated along the coast, mainly due to their dependence on the sea as the most important route of commerce and to the geological, geomorphologic and climatic constraints of the island (Porteiro et al 2005).…”

The concept of ecological structure (ESt), as implemented through spatial planning, has been recently used to protect ecosystem functions (EFs) and services and their contribution to human well-being. This study intends to provide an exploratory analysis to operationalize the inclusion of EFs in the design of ESt in territories lacking detailed individual studies on EFs. The objective is to advance this concept in small island ecosystems and use Pico Island (Portugal) as case study. The proposed methodology identifies EFs contributing to the objectives of ESt. It uses (i) geographic data available from studies on individual EFs and (ii) definition of territorial units (TUs), based on biophysical features, used as cartographic units to assign and map remaining EFs. A total of 15 EFs were selected among three main categories: natural regulation (10), support (3) and cultural (2) functions. Geographic data are available for carbon storage and groundwater recharge. To assign the remaining EFs, a total of 86 TUs were defined. The performed analysis suggested that the use of EFs, along with multi-criteria decision-making techniques, could successfully contribute to define ESt and integrate it into spatial planning on Pico Island and other small islands systems.

“…For example, red swamp crayfish [Procambarus clarkii (Girard, 1852)] might have arrived in Portugal from escapes in aquaculture facilities in Spain to the Guadiana river (Gherardi et al, 2002). Most imports to the Azores came from mainland Portugal, through commercial shipping and flights to the archipelago, mainly arriving on São Miguel island (Calado et al, 2014).…”

Non-indigenous and Invasive Freshwater Species on the Atlantic Islands of the Azores Archipelago

et al. 2021

Freshwater systems on remote oceanic islands are particularly vulnerable to biological invasions. The case of freshwater ecosystems in the Azores Archipelago is especially relevant considering the islands’ youth and remoteness, and low natural connectivity. This study presents a review of the introduction and presence of non-indigenous freshwater species in the Azores, retrieved from various historical records, paleoenvironmental reconstructions, published records, and field data from two decades of the Water Framework Directive (WFD) monitoring programs. At least 132 non-indigenous freshwater species have successfully established in the Azores, belonging to several taxonomic groups: cyanobacteria (10), synurophytes (1), desmids (1), diatoms (20), plants (41), invertebrates (45), amphibia (2), and fishes (12). Intentional and accidental introductions have been occurring since the establishment of the first human settlers on the archipelago, impacting freshwater ecosystems. The first reported introductions in the Azores were intentional fish stocking in some lakes. Non-deliberate introductions have recently increased through transport-contaminants (51%) associated with the aquarium trade or agricultural products. In the Azores, the highest number of non-indigenous species occur on the largest and most populated island, São Miguel Island (116), followed by Flores (68). Plants constitute the most representative group of introduced species on all islands, but invertebrates, diatoms, and fishes are also well established on most islands. Among invertebrates, non-indigenous arthropods are the most well-established group on all islands except on the smallest Corvo Island. Many non-indigenous species will likely benefit from climate change and magnified by globalization that increases the probability of the movement of tropical and subtropical species to the Azores. Present trends in international trade, importations, and enhanced connectivity of the archipelago by increasing flights and shipping will probably promote the arrival of new species. Augmented connectivity among islands is likely to improve non-indigenous species dispersal within the archipelago as accidental transportation seems to be an essential pathway for non-indigenous freshwater species already present in the Azores.
