JJ Kotze MSc (Zoology) Compiled by JJ Kotze 2 Updated & Revised February 2014 Faunal study Rietvallei 180 IQ 1 INTRODUCTION The fauna surveys focused on the current status of threatened species occurring, or likely to occur, within the proposed development area, and on describing the available and sensitive habitats and any potential impacts posed by the proposed development to these habitats. 1.1 Objectives of the faunal surveys • To provide a description of the fauna occurring at and in close proximity to the proposed development area. • To identify faunal species of conservation importance. • To determine potential impacts of the proposed development on the fauna • To provide management recommendations to mitigate negative and enhance positive impacts. 1.2 Scope of study • Amphibian, reptile and small mammal surveys, recording sightings and/or evidence of existing fauna. • An assessment of the ecological habitats, evaluating conservation importance and significance, with special emphasis on the current status of threatened animal species (Red Data species), within the proposed development area. • Literature investigations with which to augment field data where necessary. • Identification of potential ecological impacts that could occur as a result of the development and assess the significance of these, where possible. • Investigate feasible and practical management recommendations that should be implemented to reduce or minimise the impacts, should the project be approved. • Documentation
