Anthropogenic activities such as logging and mining play important roles in the economies of many countries worldwide. However, the benefits derived come at a detrimental cost to ecological integrity of forest systems. The impacts are often severe in developing countries where logging and mining occur pervasively and illegally especially in protected forest areas. Traditional methods of mining, i.e. without the use of heavy machinery or equipment (e.g. excavators) are still practiced in some parts of the world. This method of mining referred to as ‘galamsey’ in Ghana is purported to cause less damage to the vegetation by removing less flora compared to commercial mining. Nevertheless, not much work has been done to assess its impacts along with artisanal logging on fauna assemblages in tropical forests. 

 

 

   

In this research, I will examine the response of small mammal communities to artisanal logging and mining (i.e. galamsey) in a highly biodiverse forest located in Ghana. Small mammals are ideal for this study because they are sensitive to anthropogenic disturbances and are known to contribute significantly to ecosystem functions (e.g. seed predation and dispersal). Additionally, they are an important source of food protein in many homes globally (e.g. Africa, Asia, etc.). The investigation will be achieved using a combination of live trapping protocols established at multiple locations per disturbance category within the Atewa forest. Furthermore, an investigation will be conducted to assess the recovery of small mammals under different restoration schemes using meta-analytical approaches. Overall, this research will seek to address the following questions below:

  • Are small mammal densities/abundance affected by habitat change due to artisanal logging and mining?
  • Does artisanal logging and mining influence small mammal diversity?
  • Are small mammal parasitic loads influenced by habitat modifications caused by artisanal logging and mining?
  • Are successful small mammal recoveries determined by type of restoration scheme post mine closure?
