Figure 39. View west towards Hoedkop, looking across Pan 2 and the water that accumulated in the ditch dug across its centre from the unexpected 30 mm of rain that fell the fortnight before. ..................................................................................... 96 Figure 40. Panoramic view along the south side of Windhoekberg W, showing the steep, shaded southern slope, the collections of rocks and gravels forming a skirt around its base, and the small drainage lines formed by previous runoff. Note the lack of mountains to the west towards Springbok and the Namaqualand habitats. .. 97 Figure 41. Panoramic view over the north side of Skelemberg, showing the less steep, sunny northern slope, with fewer rocks and gravels forming less of a skirt around its base, but many small drainage lines from previous runoff and denser bushes around the 'gutter'. Hoedkop is on the left and the Aggeneys mountains on the centre horizon. .................................................................................................. 97 Figure 42. Patch of green vegetation formed on the gravel skirt below the north slope of the western Windhoekberg, from runoff and seepage after the 30 mm of rain that fell a fortnight previously. ......................................................................................... 98 Figure 43. Flowers blooming and succulents growing on the gravel skirt below the north slope of the western Windhoekberg, after the 30 mm of rain that fell a fortnight previously. ............................................................................................................... 98 Figure 44. A patch of succulent mesembryanthemums/vygies flowering on a patch of rocks and gravels at the crest of red dunes just south of Aggeneys, after the 30 mm of rain that fell a fortnight previously. Hoedkop on the left and Skelemberg on the right horizon. ........................................................................................................... 99 Figure 45. A north-easterly view from Windhoekberg towards Springbok. Note the two main habitat types of the study: terrestrial to the left and rupiculous towards the right. ...................................................................................................................... 113 Figure 46. A view of red dunes and their vegetation in the foreground. Skelemberg is on the right-hand side and in the distance Windhoekberg lies on the left-hand side. .............................................................................................................................. 114 Figure 47. Typical natural rupiculous habitat on the unnamed hill near the farmhouse. .............................................................................................................................. 114 Figure 48. Habitat on Skelemberg. Note the rupiculous habitat on the left and the red sand and dunes to the left. .................................................................................... 115 Figure 49. Man-made rupiculous habitat in natural terrestrial habitat. Often many species use these structures for refuge. ................................................................ 115 Figure 50. Man-made quarry on the western side of the study site. In the background is Windhoekberg. ............................................................................... 116 Figure 51. A dry pan in the Koa River drainage line with Skelemberg on the left. .. 116 Figure 52. A man-made dam in the Koa River drainage line, with Hoedkopberg in the background. .......................................................................................................... 117 Figure 53. A view west from the man-made dam in the northeast corner of the study site. Note Hoedkopberg in the background. .......................................................... 117 SATO Aggeneys July 2011 10
Figure 54. An easterly view from Bobbejaansgat towards Windhoekberg. Note the cement weir and the pool of water in the foreground. Such artificial aquatic sources can create habitat for the Namaqua stream frog and other frog species. ............... 118 Figure 55. A view to the west from Windhoekberg. Note the few quiver trees. The farmhouse is in the centre of the picture with flat terrestrial habitat surrounding it. On the left is Skelemberg and in the distance on the right lies Ghaamsberg. .............. 119 Figure 56.
