H3.3 Macaronesian Inland Cliff
European Red List of Habitats - Screes Habitat Group H3.3 Macaronesian inland cliff Summary The perennial vegetation of crevices and ledges of cliff faces in Macaronesia away from coastal salt-spray is of very diverse character - some, for example, dominated by succulents, others rich in ferns and bryophytes characteristic of shaded situations - and it includes several hundreds of taxa endemic to the archipelagoes. The main threats are mountaineering and rock climbing, outdoor sports and leisure activities, and construction of infrastructures such as roads and motorways. Synthesis There is no evidence of significant past reductions, either in the last 50 years or historically, and also future prospects are good, as no serious threats are envisaged, besides touristic/leisure activities and putative faulty environmental impact assessments that may overlook this habitat as valuable. Reduction in quantity, reduction in quality and criteria of geographic distribution yield the Least Concern (LC) category. In spite of the LC category, conservation policy and management should restrict to the maximum any threat to or reduction of the habitat, as it has a very high conservation value, because of high endemism of species and communities with many local and regional variaties. Overall Category & Criteria EU 28 EU 28+ Red List Category Red List Criteria Red List Category Red List Criteria Least Concern - Least Concern - Sub-habitat types that may require further examination Four general subtypes can be distinguished based on species composition and different ecological conditions. However, at present, no data are available to carry out an individual assessment of each of them. In the future, if detailed plot sampling has been carried out, such an evaluation may be possible. -

Received: 18 May 2020; Accepted: 2 June 2020; Published: 3 June 2020 Abstract: The genera Dracaena and Sansevieria (Asparagaceae, Nolinoideae) are still poorly resolved phylogenetically. Plants of these genera are commonly distributed in Africa, China, Southeast Asia, and America. Most of them are cultivated for ornamental and medicinal purposes and are used in various traditional medicines due to the wide range of ethnopharmacological properties. Extensive in vivo and in vitro tests have been carried out to prove the ethnopharmacological claims and other bioactivities. These investigations have been accompanied by the isolation and identification of hundreds of phytochemical constituents. The most characteristic metabolites are steroids, flavonoids, stilbenes, and saponins; many of them exhibit potent analgesic, anti-inflammatory, antimicrobial, antioxidant, antiproliferative, and cytotoxic activities. This review highlights the structures and bioactivities of flavonoids and stilbenoids isolated from Dracaena and Sansevieria. Keywords: Dracaena; Sansevieria; biological/pharmacological activities; flavonoids; stilbenoids 1. Introduction The taxonomic boundaries of the dracaenoid genera Dracaena and Sansevieria have long been debated. -
Gradient Analysis of Exotic Species in Pinus Radiata Stands of Tenerife (Canary Islands) S
The Open Forest Science Journal, 2009, 2, 63-69 63 Open Access Gradient Analysis of Exotic Species in Pinus radiata Stands of Tenerife (Canary Islands) S. Fernández-Lugo and J.R. Arévalo* Departamento de Ecología, Facultad de Biología, Universidad de La Laguna, La Laguna 38206, Spain Abstract: Identifying the factors that influence the spread of exotic species is essential for evaluating the present and future extent of plant invasions and for the development of eradication programs. We randomly established a network of 250 plots on an exotic Pinus radiata D. Don plantation on Tenerife Island in order to determine if roads and urban centers are favouring the spread of exotic plant species into the forest. We identified four distinct vegetation groups in the P. radiata stands: advanced laurel forest (ALF), undeveloped laurel forest (ULF), ruderal (RU), and Canarian pine stand (CPS). The groups farthest from roads and urban nuclei (ALF and CPS) have the best conserved vegetation, characterizing by the main species of the potential vegetation of the area and almost no exotic and ruderal species. On the other hand, the groups nearest to human infrastructures (ULF and RU) are characterized by species from potential vegetation’s substitution stages and a higher proportion of exotic and ruderal species. The results indicate distance to roads and urban areas are disturbance factors favouring the presence of exotic and ruderal species into the P. radiata plantation. We propose the eradication of some dangerous exotic species, monitoring of the study area in order to detect any intrusion of alien species in the best conserved areas and implementation of management activities to reduce the perturbation of the ULF and RU areas. -

African countries and neighbouring islands covered by the Synopsis. S T R E L I T Z I A 23 Synopsis of the Lycopodiophyta and Pteridophyta of Africa, Madagascar and neighbouring islands by J.P. Roux Pretoria 2009 S T R E L I T Z I A This series has replaced Memoirs of the Botanical Survey of South Africa and Annals of the Kirstenbosch Botanic Gardens which SANBI inherited from its predecessor organisations. The plant genus Strelitzia occurs naturally in the eastern parts of southern Africa. It comprises three arborescent species, known as wild bananas, and two acaulescent species, known as crane flowers or bird-of-paradise flowers. The logo of the South African National Biodiversity Institute is based on the striking inflorescence of Strelitzia reginae, a native of the Eastern Cape and KwaZulu-Natal that has become a garden favourite worldwide. It sym- bolises the commitment of the Institute to champion the exploration, conservation, sustain- able use, appreciation and enjoyment of South Africa’s exceptionally rich biodiversity for all people.

Utilising a family-run hotel on the outskirts of the ancient city of Arles as our base, the itinerary provided an easy opportunity to look for flamingoes, herons and wading birds using the shallow waters and reed-fringed lagoons as a breeding area or a suitable stop-over for migrants. The mountainous areas attract different and more localized species and we located special birds such as Wallcreeper, Rock Sparrow and Booted Eagle, together with a selection of other stunning species that call the Camargue home. Day 1 Monday 19th November Arriving in the early evening, leaders Neil and Matt met 15 of the 16 clients at Marseille airport, before collecting the minibuses and beginning the journey to the hotel. French protests and road blocks meant the route was more cross country but after just over an hour or so we arrived at our destination, Hotel des Granges. We were greeted by Bruno and Marie-Jo, our wonderful hosts and owners of this classically French Hotel, and a lone Black Redstart, the first bird for our trip, sat roosting over the entrance porch. -

A LONS O5 an d Luis M . C ARRASCA L6 SUMMARY .— New data on the population, distribution and habitat preferences of the Canary Islands stonechat Saxicola dacotiae . This paper updates estimates of population size, distribution and habitat preferences of the endemic Canary Islands stonechat Saxicola dacotiae on the basis of data gathered across their whole distribution range, the island of Fuerteventura. We surveyed 1,462 0.5-km line transects during the reproductive seasons in 2005 and 2006, distributed across the whole island. Results were used to estimate population size using two methods: stratified estimates of mean densities and sum of estimated abundances across strata, and sum of estimations of abundance in 1 km x 1 km UTM squares based on statistical models built by boosted regression trees (BRT). In both methods we accounted for the effects of bird detectability in transects. Overall, 490 mature individuals were recorded. The Canary Islands stonechat preferred high, steep terrain (particularly above 20% slope and 200 m a.s.l.) and selected negatively the lower and flatter areas comprising most of the island. These habitats were occupied, however, albeit at low density. The highest average densities sampled per habitat (up to 43 birds/km 2) were registered on steep areas (> 11%) with scrub, although the statistical models predicted densities of 66 birds/km 2 in the optimum 1 Grupo de Ecología Terrestre (TEG), Departamento de Ecología, Universidad Autónoma de Madrid . -
