Goat grazing management is a powerful ecological force structuring plant communities which effects are highly different depending on factors such as climatic conditions, intensity, type of community, etc. Pastures in the Canary Islands have important heritage, socioeconomic and landscape values because they remains traditional livestock key element local economy. An experimental study goat exclusion has been carried out an area La Gomera Island to determine main abandonment species richness...
Abstract Question How are semi‐natural ecosystems affected by goat grazing regime (heavy, light and long‐term abandonment)? Location Anaga R ural P ark, T enerife I sland, C anary slands ( S pain). Methods We evaluated plant species composition, diversity structure (frequencies of functional groups based on growth form bare ground) for three regimes using 63 permanent point‐quadrat transects. The effect orientation N vs slope) was also analysed. Data were collected in the spring during each...
Seedling dynamics of the Macaronesian laurel forest have been monitored for first time in a long-term study to determine whether survival seedling community is affected by slope aspect and structure. More than 4000 seedlings were monthly from 2000 2003 well-preserved stands on Tenerife, Canary Islands. Trees bank species composition differed between windward leeward slopes. On both slopes, differences canopy suggest future shifts towards more advanced successional stage. Surprisingly, was...
In this study, we analysed the effect of a wildfire that occurred in 2007 well-preserved Canarian pine forest located ‘Integral Natural Reserve Inagua’. This reserve has highest level protection Network Protected Areas. 2009, established an area was affected by fire central part grid quadrats 500×500m size. Following corners quadrats, set up network 28 permanent square plots 25×25m. Ten more were randomly surrounding unaffected fire, with similar vegetation and environmental conditions. We...
Abstract Invasion biology is an important element of global environmental change and represents one the main threats to biodiversity. American species were introduced Tenerife after Spanish conquest during eighteenth century, as case for Agave americana Opuntia dillenii . The long period naturalization adaptation these has led them become two most dispersed archipelago. We analyzed several eradication management processes in area intensively invaded by both O. A. Three treatments randomly...
Prescribed fires are a powerful tool for reducing fire hazards by decreasing amounts of fuel. The main objective is to analyze the effects prescribed burning on understory vegetation composition as well soil characteristics reforested stand Pinus canariensis . study attempts identify preburning treatment cutting floristic parameters community. This was carried out two years following in Canarian pine stand. Cutting and affected species increased diversity. Burnt cut plots were characterized...
Historically, fire has played a dominant role in shaping many forest plant communities. Mediterranean-type vegetation is one of the world's major fire-prone biomes, with conifer forests among most flammable ecosystems Mediterranean region. Prescribed fires are powerful tool for reducing hazards by decreasing amounts fuel. The main objective this work to analyse effects prescribed burning on understory composition and species richness reforested stand Pinus canariensis. Nine 900 m2 plots were...
The question of how plant species foreign to a biological system can disperse and turn into an environmental problem is very important for the control invasive species, especially insular ecosystems, which are more susceptible invasions.We analyzed role played by European rabbit (Oryctolagus cuniculus) in seed dispersal scrub Acacia farnesiana Gran Canaria (Canary Islands).The results indicated that A. food resource rabbits use all year long.We found high percentage undamaged seeds (9.77%)...
Identifying the factors that influence spread of exotic species is essential for evaluating present and future extent plant invasions development eradication programs.We randomly established a network 250 plots on an Pinus radiata D. Don plantation Tenerife Island in order to determine if roads urban centers are favouring into forest.We identified four distinct vegetation groups P. stands: advanced laurel forest (ALF), undeveloped (ULF), ruderal (RU), Canarian pine stand (CPS).The farthest...
The recovery and survival of the Macaronesian laurel forest depends on its regeneration strategies. After years long-term monitoring, both sexual asexual appear to be equally important. However, mechanisms for each are just beginning understood. In order contribute understanding regeneration, we analyzed species composition seedling bank every two weeks over three in Anaga (Tenerife, Canary Islands). We compared compositions with canopy, changes their diversity this period different stands....
