Monitoring Avifauna in Tulawaka - with recommendations for affirmative action. Report to Pangaea Mining.

To record and assess the avifauna within the Tulawaka mine site, this is defined by those areas inside the 10.4km perimeter fence. In main objective was to set in place a system of monitoring any potential change in species diversity or frequency due to mining activities. A bird list was established by general observation throughout the site from the 7th – 10th October 2004, and in order to create a monitoring system, a series of Timed Species Counts were conducted in those areas considered most likely to be effected by mining activities. Following discussion, the TSC survey was conducted within Brachystegia woodland, located to the north-west, west and south-west of the tailings dam. This area was chosen due to the yearly prevailing wind direction from a potentially polluting source.

Timed Species Counts (TSCs) were carried out in two time sections (0600–0830 / 1630–1800) over a period of three days (8th – 10th October 2004). The location of each count was marked using GPS and recorded as UTM coordinates, no record of habitat condition or weather was taken. However should this habitat become degraded due to an extension (west) of the current waste rock site, this must be taken into consideration.

All TSC data was collected over a 30 minute time period, sub-divided into 5 minute time intervals, giving a TSC index score for each species of 6 – 1 respectively. Each species was recorded as near (within 25m) or far (outside 25m), with an estimated error of 5%. ONLY those species recorded by SIGHT within the 25m radius are used for analysis. Each of the count sites was marked in sequential order using pink spray paint.
