Scientific Name: Microgale jobihely
Species Authority: Goodman, Raxworthy, Maminirina & Olson, 2006
Common Name(s):
English Northern Shrew Tenrec
Taxonomic Notes: A recently described species of tenrec, having a sister relationship with the much more widespread Microgale cowani (Goodman et al. 2006).

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Hoffmann, M.
Reviewer(s): Stephenson, P.J. & Rathbun, G. (Afrotheria Red List Authority)
Justification:
Listed as Endangered as the species is known only from the southwestern slopes of the Tsaratanana Massif, is entirely outside of the protected areas network, and is faced with considerable anthropogenic pressure.

Geographic Range [top]

Range Description: Microgale jobihely is known only from two sites on the south-western slopes of the Tsaratanana Massif in madagascar across an elevational gradient from 1,420 to 1,680 m (Goodman et al. 2006). It appears to be the only member of this genus that is a very localized endemic (Goodman et al. 2006).

Population: Currently known from 12 specimens taken at two sites on the south-western slopes of the Tsaratanana Massif.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The holotype was collected in montane forest habitat near Matsaborimena Lake. According to Goodman et al. (2006), the largest trees at the site are about 15 m tall, the canopy is partially open, the sub-canopy contains few lianas, sparse herbaceous ground cover, and on slopes and in valleys a considerable number of downed and rotten tree trunks. The site, which is relatively close to the village of Bemanevika, is partially disturbed, with numerous trails associated with different minor types of forest exploitation, including cattle grazing.

The second locality where the other 11 specimens were taken is the Analapakila Forest, which shows considerable signs of anthropogenic disturbance. At this site the canopy is open, the remaining trees are notably separated from one another, the sub-canopy has a dense growth of small lianas, and the forest floor has considerable fallen and decomposing tree trunks and branches. The site is located next to an extensive marsh, which has been partially converted to rice paddy. Within the forest there are numerous signs of human disturbance, including cattle grazing, wood cutting, hunting of forest animals and coffee cultivation (Goodman et al. 2006).
Systems: Terrestrial

Threats [top]

Major Threat(s): The two sites from which this species has been recorded are in a relatively remote forested region extending off the
south-western flank of the Tsaratanana Massif. In both the foret du lac Matsiborimena and the foret d’Analapakila, there is local human pressure on the forest, mostly in the form of slash and burn agriculture (tavy), as well as non-commercial timber extraction. Furthermore, the marshlands close to the sites from which this species was obtained are being converted to rice paddies (Goodman et al. 2006).

Conservation Actions [top]

Conservation Actions: The area where the species has been recorded is outside the protected area of the Reserve Naturelle Integrale du Tsaratanana.
