• Observed important species Attributes observed in the field: • Dominant vegetation as an indication of status of the wetland Wetlands should be seen as a system and not as separate entities. For this reason wetland sections were combined. For example, some portions of a floodplain riparian wetland may change to non-floodplain riparian or seepage (up-stream or downstream of the floodplain), but since it is part of the same system it has been included as part of the floodplain riparian wetland. 4.3 Field verification of the wetlands Field verification of the wetlands took place as part of the second phase of the project. The field verification was divided into two portions: o Field verification of wetlands throughout the catchment, and o Field verification of wetlands on the mining properties. For the first part of the field verification the wetlands adjacent to public roads were verified. The location of the wetlands were marked using a Garmin GPS 60 and, where possible, a photograph was taken of the site. The observed status, connectivity and threats to the wetland were noted, as well as, the dominant vegetation in the wetland. Since there are more public roads in the southern portion of the catchment, and most of the mines are located in this area, verification of the wetlands was focussed in the southern portion of the catchment. For the second part of the verification phase the wetlands on the mine properties were verified. The various environmental and safety officers at the mines were contacted for appointments to visit the mines and to serve as guides to the wetlands. The same data was collected for the wetlands at the mines as at the previous field verification site visit wetlands adjacent to the public roads. The UORC wetland database was corrected using the information obtained from the field verification site visits. Wetland Database for UORC - 78 -
Since the field verification site visits enabled us to get a clearer picture of which areas are wetlands and which not, the wetland database was reviewed again on the aerial photographs and corrections made. 5. RESULTS AND DISCUSSION 5.1 Wetland maps Wetlands and dams in the UORC were delineated based on the aerial photographs. Field verification of the wetlands was completed as part of the second phase of the project. The final wetland database is indicated in Figure 16 and the dam layer in Figure 17. Figure 16.
