THE EUROPEAN PINE MARTEN MARTES-MARTES IN THE BALEARIC-ISLANDS, SPAIN

Between March and December 1990, a survey of Pine Marten Martes martes L. on the Balearic Islands of Minorca and Majorca was carried out. Pi ne Marten were found distributed over 55% of Minorca and occupied Alep po Pine and Holm Oak forests, mediterranean shrublands and riparian/cl iff habitats. In Majorca, Pine Marten were found on 48% of the island and three broad physiographic areas, the Sierra de Tramuntana, Sierra de Levant and the Massif de Randa. Droppings were collected along four designated routes during five bimonthly intervals in Minorca to descr ibe the Pine Marten's differential use of habitat types. The upland/op en pine forest had the highest use index while the Holm Oak forest had the lowest. The number of Pine Marten faeces collected was greatest d uring the months of July-August. The Balearic Island Pine Marten popul ations were once on the verge of extinction; however, protection durin g the last 20 years has enabled the species to recover throughout most of the forested habitats on both islands. Resource managers must care fully monitor the Pine Marten populations to provide the species and i ts habitat with adequate protection and management in the future.
