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. -

Effect of Fire Intensity on Non-Native Plant Species Community in a Canarian Pine Forest Three and Eleven Years After Fire C
70 The Open Forest Science Journal, 2009, 2, 70-77 Open Access Effect of Fire Intensity on Non-Native Plant Species Community in a Canarian Pine Forest Three and Eleven Years After Fire C. García-Domínguez* and J.M. Fernández-Palacios Departamento de Ecología, Facultad de Biología, Universidad de La Laguna, La Laguna 38206, España Abstract: The invasion of non-native plant species is one of the greatest threats to natural ecosystems, and oceanic islands are especially susceptible to this threat. Fire, as a disturbance factor, has been found to promote non-native species invasion and fire intensity is one of the variables determining the severity of invasions. This study was designed to determine the impact of non-native species in the Tenerife pine forest understory on the island of Tenerife, Canary Islands, Spain, and how they are affected by low and high intensity wildfire. We resampled in 2006 the plots set for a previous study in 1998 within the area affected by a wildfire in June 1995. Six control plots, nine low-severity burned plots and twelve high-severity burned plots were sampled three and eleven years after fire. Native species cover increased in high severely burned plots with respect to control plots. It also increased in low and high severely burned plots from 1998 to 2006. No differences were found for non-native cover and richness between fire intensities or in time. Results suggest that some of the native understory plant species are adapted to high intensity fire and respond by increasing their cover after fire to the detriment of non-native species. -

Other typically herbaceous dicotyledonous groups in which species of the Atlantic Islands are appreciably woodier than non-insular ones include Centaurea and Sonchus ( Asteraceae); Cheiranthus, Crambe, Descurainia, Parolinia, and Sinapodendron ( Brassicaceae); Convolvulus ( Convolvulaceae); and Plan tago ( Plantaginaceae). The tendency for Macaronesian species to be woodier than their main land relatives has naturally given rise to interpretations. The rosette shrubs of these islands are quite characteristic; such shrubs were termed "Feder buschgewachse" by Schenck ( 1907). These suggest to some workers her baceous groups in which the notably moderate climate of islands has per mitted continued growth; in these groups there is natural selection for plants that are of longer duration and increased woodiness, suiting the year-long growing season of such insular areas. -
The Canary Islands
The Canary Islands Dragon Trees & Blue Chaffinches A Greentours Tour Report 7th – 16th February 2014 Leader Başak Gardner Day 1 07.02.2014 To El Patio via Guia de Isora I met the half of the group at the airport just before midday and headed towards El Guincho where our lovely hotel located. We took the semi coastal road up seeing the xerophytic scrub gradually changing to thermophile woodland and then turned towards El Teide mountain into evergreen tree zone where the main tree was Pinus canariensis. Finally found a suitable place to stop and then walked into forest to see our rare orchid, Himantoglossum metlesicsiana. There it was standing on its own in perfect condition. We took as many pics as possible and had our picnic there as well. We returned to the main road and not long after we stopped by the road side spotting several flowering Aeonium holochrysum. It was a very good stop to have a feeling of typical Canary Islands flora. We encountered plants like Euphorbia broussonetii and canariensis, Kleinia neriifolia, Argyranthemum gracile, Aeonium urbicum, Lavandula canariensis, Sonchus canariensis, Rumex lunaria and Rubia fruticosa. Driving through the windy roads we finally came to Icod De Los Vinos to see the oldest Dragon Tree. They made a little garden of native plants with some labels on and the huge old Dragon Tree in the middle. After spending some time looking at the plants that we will see in natural habitats in the following days we drove to our hotel only five minutes away. The hotel has an impressive drive that you can see the huge area of banana plantations around it. -

This is probably the most well known location on Tenerife as it is where most people see their first Blue Chaffinches and we were not to be disappointed. Also at this location we saw the only Great Spotted Woodpecker of the tour plus a few Canaries, a Tenerife Kinglet and a few African Blue Tits. After departing from Las Lajas we continued climbing and entered the Las Cañadas National Park which is a spectacular drive through volcanic scenery. On the drive we encountered quite a few endemic plants including Pinus canariensis and Spartocytisus supranubius that were common and easily recognized and Echium wildpretii, Pterocephalus lasiospermus, Descurainia bourgaeana and Argyranthemum teneriffae which were rather unimpressive as they were not yet flowering but we were compensated by the fabulous views across the ancient caldera. -
