Unique collections held and curated at the Museum is a useful reference tool that allows to monitor long-term environmental changes in the protected areas of the province after comparison with the data obtained during the latest fieldwork. Many interesting observations were made in result of continuous collaboration with University of KwaZulu-Natal and Ezemvelo KZN Wildlife in some of those protected areas.
For example, both Dlinza Forest and Entumeni Nature Reserve have been already thoroughly sampled for molluscs. Our collection has 20 species from Dlinza Forest with total of 44 observations recorded from 1985 to 2004 and 19 species from Entumeni with total of 38 observations recorded from 1981 to 2005.
Even to our own surprise, six species were reported from Dlinza Forest for the first time in result of our latest survey of that area in 2019. See Trachycystis glanvilliana (Ancey, 1893) [shell diameter: 4.8 mm] for example.
Fieldwork in Entumeni Nature Reserve has been even more productive: 13 species were recorded in result of our 2019 survey for the first time. See Microkerkus leucospira (L. Pfeiffer, 1857) [Sub-adult. Shell diameter: 10.5 mm] for example. It should also be noted that 10 out of 19 species previously known from Entumeni NR were not found during our 2019 survey.
Considering that only two days were spent at each above-mentioned Nature Reserve during our 2019 survey, additional collecting effort could further increase number of species known from these Nature Reserves and to the entire area in proximity of Eshowe.
