Introduction
This section presents the Environmental Assessment (EA) for the effects of the
slurry pipeline on fauna, including potential impacts on rare and locally endemic
species, faunal movement and faunal health, as per the Ambatovy Project (the
project) Terms of Reference and issues raised during consultation (Volume H,
Appendix 1; Volume A, Section 6).
This EA includes a baseline summary of survey results for key taxa and a
summary of key issues. For each identified issue, the following topics were
addressed:
•
evaluation of potential impact pathways;
•
assessment methods;
•
assessment criteria;
•
mitigation;
•
impact analysis;
•
residual impact classification;
•
prediction confidence; and
•
monitoring.
A summary of the main impacts as they relate to key species and habitats is
provided.

Study Area
The slurry pipeline Local Study Area (LSA) includes the approximately 195 km
slurry pipeline footprint, plus a 1 km buffer on either side of the proposed
pipeline route, from the ore body complex at the mine site to the plant site near
Toamasina (Figure 7.2-2, Volume A).
The LSA has been divided into three major land use sub-areas: the western
section, which is within the forest corridor (corridor zone); the central section,
which passes around primary zonal forest fragments through an area defined
primarily by a tavy matrix (tavy zone), and the eastern section, containing
entirely secondary vegetation and has a higher density of agricultural use, called
