It is possible that in recent decades we have been witnessing changes in the distribution and abundance of two carnivore species: the weasel and the stone marten.

Weasel (Vormela peregusna) is a small carnivore in the weasel family (Mustelidae), with most observations in Israel coming from the Mediterranean region. In the 1970s, weasels were also observed in the northern Negev and even in the northern Arava, and it was then suggested that the species had penetrated those desert areas following the expansion of agricultural lands into them. Due to the limited information, it is not possible to confirm or reject hypotheses regarding the relationship between changes in the species' distribution and the expansion of agricultural areas in the region. Another carnivore species that has been surprising us in recent years at new sites is the Stone Marten (Martes foina). It appears that the species has expanded its range southward and is now also seen in the northern Negev. Regarding it, it should be noted that besides its appearance in new geographical areas, it seems to adapt well to inhabited areas and even enters dwellings.

Please pay attention to the report of a stone marten found roadkill in Kadumim (Noam Segev). Noam writes that he has never observed a weasel in the Kadumim area, although he often hikes there. Anyone who has information about weasel sightings is asked to use the system and share the information, so that we can substantiate or refute the claim that was heard, according to which there may be competition between the species also in the Mediterranean region.

In the attached photo - a sighting of a weasel from north of the Negev:
An individual found roadkill on the access road to Kibbutz Mashabei Sadeh (18/05/1995).
Since then, no sightings are known from the vicinity of the site.
