ICP Forests biodiversity dataset for Solling (ID 04_304, ID 04_305), time frame 1994 to 2019

The dataset contains vegetation cover from 1x1 64 permanent plots along an altitudinal gradient (1722-1978 m a.s.l.) established in four summits in the northen Apennines. The plots are arranged at the four cardinal directions of each summit. The samples are collected every 5/7 years. The data are collected according to the GLORIA Multi-Summit Approach.

In 2012 permanent plots with size of one square meter were established, to occupy the vegetational developement of alpine grassland with Kobresia myosuroides, in aspects of climate change and long-term monitoring Data records are presented from 23.07.2012 to 30.08.2012 Data includes vegetational coverage in 43 different plots and pH-values of soils measured in 29 plots

We are interested in the interplay and impacts of disturbances, climate change and nitrogen deposition on tree regeneration (Picea abies) in the high elevations of the Bavarian Forest National Park. The process of forest recovery is thereby significantly slowed down by a native grass species (Calamagrostis villosa) which became increasingly competitive due to the sudden, environmental shifts induced by the bark beetle outbreak. This new competitor grows faster than the spruce in conditions of clear cuts, which means higher light and nutrients availability. Furthermore, the productivity of C. villosa is additionally favored by the input of N due to human activity, especially agriculture. We sampled species richness and abundances (spermatophytes), grass biomass and tree regeneration in a systematic grid-based plot sampling. Furthermore, we analyzed data on reproduzing P. abies in the sourrounding area. Additionally, we investigated species richness and abundances (spermatophytes and mosses), pH, salinity and temperatures of forest springs.

In 1985 the Corine programme was initiated in the European Union. Corine means 'coordination of information on the environment' and it was a prototype project working on many different environmental issues. The Corine databases and several of its programmes have been taken over by the EEA. One of these is an inventory of land cover in 44 classes, and presented as a cartographic product, at a scale of 1:100 000. This database is operationally available for most areas of Europe (http://www.eea.europa.eu/publications/COR0-landcover).

19 different types of habitats have been identified and mapped over the extent of the Samaria National Park area. The habitats identified, according to Natura 2000 classification, are: 1120-Posidonia beds (Posidonion oceanicae), 1240-Vegetated sea cliffs of the Mediterraneancoasts with endemic Limonium spp., 1310-Salicornia and other annuals colonising mud and sand, 2230-Malcolmietalia dune grasslands, 3170-*Mediterranean temporary ponds, 4090-Endemic oro-Mediterranean heaths with gorse, 5420-Sarcopoterium spinosum phryganas, 5430-Endemic phryganas of the Euphorbio-Verbascion, 6220-*Pseudo-steppe with grasses and annuals of the Thero-Brachypodietea, 8140-Eastern Mediterranean screes, 8210-Calcareous rocky slopes with chasmophytic vegetation, 8310-Caves not open to the public, 8320-Fields of lava and natural excavations, 9290-Cupressus forests (Acero-Cupression), 9320-Olea and Ceratonia forests, 9540-Mediterranean pine forests with endemic Mesogean pines, 92C0-Platanus orientalis and Liquidambar orientalis woods (Plantanion orientalis), 92D0-Southern riparian galleries and thickets (NerioTamaricetea and Securinegion tinctoriae) and 934A-Greek Quercus coccifera forests. Of these types, some are considered already in a critical state, while others are well established and thriving. Furthermore, the classification takes into account the habitats' spread pattern in order to assess their conservation priority level. Thus, three classes of priority have been established, with 5 out of 16 habitats' identified ranking in the highest class of importance.
