Abstract

To conserve biodiversity, complementary approaches are necessary. Besides using museum data from sightings and specimens, the knowledge of experts can also be employed. Often such valuable information is lost on retirement or death. To investigate the value of this knowledge for nature conservation planning, we sent questionnaires to 124 professional conservationists in the province of KwaZulu-Natal, South Africa. Fifty-two replies illustrated that the historical context biases our concepts of nature and the conservation of biodiversity. Despite an awareness of all the spatial scales, complexities and dynamics of nature, there is still a strong focus on large-sized animals and visibly discrete ecosystems, such as wetlands. Nevertheless, the respondents illustrated that an awareness of infrequently-seen and less well known organisms is increasing. Harnessing this expert knowledge was valuable for conservation planning, but had the weakness that many taxa and localities were neglected. Similar problems arose with data from museum specimens. However, both these approaches were synergistic and highlighted the geographical areas that need far more exploration of their biodiversity. Such information gathering is an important ethical and practical exercise for conserving biodiversity.
