Interaction with infrastructure
Fauna interactions with infrastructure are expected to occur though the impact of
such hazards is difficult to predict, since such numbers are hard to obtain and are
often incomplete when available (Berger 1995).

Vehicle-Fauna Collisions
Vehicle-fauna collisions are expected to occur and be greatest in areas of highest
or continuous traffic volume and in high value habitats. Traffic volumes are
predicted to be highest along the haul roads. In addition, vehicle traffic will
increase in the surrounding area, outside the LSA, due to the Ambatovy Project
(Volume B, Section 5.5).
