Along the southern and eastern swamp boundaries some water pollution could occur due to
human activities in neighboring dry land areas. But these activities, that are predominantly
agriculture, are limited in scale, and polluting agents are expected to be biologically degraded
very quickly. Therefore the water quality in the Wetland Area is considered as to reflect natural
conditions for the most of its extent. Water sampling in the swamp area approved this.
The waterways in the Dry land Area discharge water from residential and human-use activities as
agricultural and industrial. However, the impact of industries is expected to be very limited as
almost no factories are visible in the area.
The waterways can be polluted by substances released from these sources.
4.3 THE BIOLOGICAL ENVIRONMENT
4.3.1 VEGETATION
Records of the natural vegetation of the study area are available from the Western Wayambo
Swamp, the coast north of the Polder Weg naar Zee and from the adjacent eastern areas
(Gummels area). These records were made in 1975 to support the ecosystem mapping of
Northern Suriname (Teunissen, 1978). At that time, the entire Wayambo Swamp was only
accessible along two canals (so-called fish holes): the Durga Canal (at that time being excavated)
and along the canal of the "NV Zwampexploitatie Maatschappij" (ZEM), also known as "fish
hole Fräser". From these early records, 13 study sites are located in still existing wetlands, while
one was located in the ridge forest, now partly cleared to construct the Ensberg airstrip.
For the Environmental Baseline Study of the northern Tambaredjo area (IBT Engineering
Consultants, 1999) and the Environmental Impact Statement for the Wayambo Swamp (E2
CANADA & GOLDER, 2000), additional vegetation plots were recorded along the Durga
Canal, the Calor Canal and the Van Dijk Canal. All (56) available records of the Wayambo
Swamp were published in the above Impact Statement (E2 CANADA & GOLDER, 2000): the
complete summary of the records is provided in Appendix A, while a map of record locations are
shown in Appendix B, Figure B.1. of the PEIA study of Noordam and Teunissen (2007/2008).
Of the present wetland study area (the eastern extension of the Wayambo swamp) only the edges
are accessible (along the east side of the Van Dijk Canal, the north side of the Okrodam ridge
between Pomona and the Henri Fernandesweg and along the Henri Fernandesweg itself). From
aerial photos (CBL, 1971-73; Lufthansa 2001), satellite imagery (LANDSAT 2002, Google
Earth 2005) and fly-overs from Teunissen (2000-2007) there is no reason to assume that the
range and zoning of the vegetation types in the Eastern Wayambo Swamp differ from the those
in the adjacent better known Western Wayambo Swamp.
For the Environmental Impact Statement for the Wayambo Swamp (E2 CANADA & GOLDER,
2000), a vegetation map is presented for the Western Wayambo Swamp between Sara Maria and
the boundary between the Saramacca and Wanica District (5 th Rijweg), see Figure 4.8.1 of
mentioned report. The LANDSAT 2002 and Google Earth 2009 imagery was used to map the
present study area.
