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.

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).

An extended monitoring programme in the Samaria National Park, with semi-quantitative sampling methods to keep track of the relative abundance presence of various classes of the Arthropoda phyllum. Sampling frequency and density varies according to monitored species.
