24 | KST Re-introduction Guidelines
Population Viability Analysis and Monitoring Working Group: James Gibbs (Chair).
his thematic area focuses on KST population viability, how KST will respond to various variables, monitoring environmental aspects of the gorge, population models, etc. The Group identified eight areas/aspects that are crucial for KST and therefore need monitoring. The components are: • Microclimate of the gorge
• Water quality
• Vegetation (wetland and woody vegetation)
• Invertebrates (in the wetlands) • Amphibians • Diseases
Population Viability Analysis and Monitoring
The group assumes the current monitoring of the various components in the gorge will continue using the protocols and timeframe as detailed in Gibbs’ report.
Challenges Hydrology of the Mhalala and Jabali not understood Priority Critical Activities Monitor discharge (quantity) of Mhalala and Jabali Output Report on the discharge of the two streams produced Timeframe Three times in a year to coincide with high, medium and low flow Organization College of Engineering and Technology responsible and reports to the LKEMP
Challenges Magnitude of Microclimate change of the gorge not understood Priority Critical Activities Monitor temperature, humidity, precipitation, evaporation, solar radiation, wind Output Data on various microclimate parameters produced Timeframe Temperature and humidity to be recorded on six hourly basis using data loggers Organization RAMPO responsible for data collection and report writing and reports to LKEMP
Challenges Water quality in the sprinkler system – no information is available for sediment deposition, which will lead to growth of bacteria and fungus Priority Critical Activities - Monitor: pH, electrical conductivity, Nitrates, Ammonia, total nitrogen, Total suspended solids, IN Jabali, Handaki and KR intakes. Analysis of bacteria and fungal growth in sprinkler pipes. Output Report on water quality variables produced Timeframe pH and electrical conductivity to be measured twice per month, other parameters to be assessed twice in a year to coincide with the dry and wet season Organization Department of Aquatic Sciences and Fisheries, University of Dar es Salaam and RAMPO
