Middens (i.e. persistent 'dung-heaps') produced by Rabbits (Oryctolagus cuniculus) on a limestone quarry-spoil bank in the process of reclamation were small areas of enhanced biological activity, initiated and maintained by Rabbits, that were probably beneficial, through recycling of nutrients, to those same Rabbits.The soil of the middens, at a depth …
The open mining of limestone degrades the land surfaces including the loss of vegetation, changes in the soil structure and density, and causes erosion, and water pollution (Rai et al. 2014; Suthirat 2017). The land reclamation and revegetation in several former limestone quarries in Tuban district have been conducted.
