Baseline vegetation excludes exploration disturbances of which 33.3 ha is attributed to work conducted by the
Project and 30.2 ha is attributed to the work of GENiM and
Phelps Dodge Madagascar S.A.R.L.
These
disturbances totalling 63.5 ha are largely included within the loss/alteration values presented due to the overlap in
areas between exploration and proposed mining.
Note: Due to rounding, subtotal and totals may not add precisely to expected values.
Total amounts of direct impacts to vegetation are outlined above. The direct
impacts related to each ore body are discussed below. These impacts are broken
down for each of the two ore body zones at Ambatovy and Analamay. The
impacts outlined below are not in addition to what is described above, rather,
they are presented to help clarify the scope of project impacts in each of the areas
represented with high proportions of azonal and transitional vegetation.
Vegetation zones encompassing the azonal and transitional vegetation types
within each of the ore bodies were defined for the purposes of this EA.
