January 2006
Eight bird species observed in the pipeline LSA are listed on the IUCN Red List
and 14 species are listed by CITES (Volume J, Appendix 2.2, Table 3).
Species richness was greatest in the corridor zone. Of the 93 total species
recorded in the LSA, 35 species were found in both zones. Both exotic species
were observed in the tavy zone, but only
Acridotheres tristis
was recorded in the
corridor zone. All eight IUCN listed species observed in the LSA were recorded
in the corridor zone, but only
Accipiter madagascariensis
was recorded in the
tavy zone.

Impact Assessment
4.2.4.1 Issue Scoping
The baseline summary described the key faunal species and faunal habitat found
within the slurry pipeline LSA, particularly for species of concern (IUCN 2004;
UNEP-WCMC 2005). The purpose of the impact assessment is to assess specific
effects on the key species and habitats found within the LSA, identify strategies
to reduce potential project-related effects and discuss the potential to return the
area to pre-disturbed faunal habitat conditions. A variety of issues and concerns
were raised during consultation, with respect to potential pipeline effects on
biodiversity including fauna (Volume A, Section 6). Main issues connected to
faunal species include:
•
potential impacts to populations of rare and endangered species from
construction and operation of the pipeline and associated access roads
especially in the Mantadia-Zahamena corridor;
•
direct and indirect effects on faunal habitats from construction and
operations;
•
habitat fragmentation and potential impacts on movements of faunal
species; and
•
potential effects on faunal health due to changes in water and air quality
especially in the Torotorofotsy Wetlands.
These issues can be summarized by the following key questions:
Key Question W-1
What Effect Will the Project Have on Faunal
Abundance and Distribution?
Key Question W-2
What Effect Will the Project Have on Movement
of Faunal Species?
