Average Overall 34 37
The average overall for the NIPP site and surrounds is 34 dB (A) during wet
season and 37 dB (A) during the dry season. As with standard methodology,
the baseline noise levels are therefore considered to be below the IFC Noise
Level Guidelines for daytime, 55 dB(A) LAeq, 15hr, and 45 dB(A) LAeq, 9hr, for
night time for residential, institutional or educational receptors.
4.9 TERRESTRIAL ECOLOGY
4.9.1 Flora
The assessment of vegetation was conducted to provide information on:
• floristic composition;
• plant species including the presence or absence of species;
• profile of the vegetation type; and
• inventory of economic plants including any crops of medicinal value.
The identification of species was conducted both in situ and ex situ.
Representative samples of plant species were collected and prepared as
standard herbarium species, to serve as a record of the vegetative composition
of the area and identification of those species not identified in the field.
A combination of line and belt transect were used for the rapid assessment of
the vegetation types. The belt transect used a 10 m by 5 m plot size. The
sampling included locations at either end of the proposed Project site with
seven points sampled in total during the dry season. The same sampling points
were also chosen during the wet season to include the proposed Site in addition
to the southern and south-eastern portions of the Project site. Figure 4.7
illustrates the sampling locations for surveying vegetation.
