Another hábitats of interest

Although there is no doubt that Izki emphasises the great Pyrenean oak mass, there are also other indigenous forests like, beech, gall oaks, yews and chestnuts and with lesser representation, the oak wood, alders and willows. The small azonal enclaves of Izki have an elevated natural value both because of its rarity and its strict environmental requirements. An example of these are the mosaics of quagmires, and peat which scatter the area, the siliceous pastures or the bodies of stagnant water. The heaths, pasturelands and prairies with the rocky habitats complete the landscape of Izki, an emblematic place in the heart of Alava.
