The Threatened Species No-Go Mapping Tool: An online open-access land-use decision support tool that identifies areas of importance for highly sensitive species of conservation concern

Biodiversity is declining faster than at any time in human history, with
anthropogenic drivers causing significant alteration of 75% of the world’s
land surface. The resultant habitat loss is driving more species than ever
towards extinction, with range-restricted, endemic species most at risk.
Nevertheless, it is unrealistic to believe that development will suddenly
cease; thus, achieving conservation goals whilst simultaneously promoting
sustainable development requires integrated landscape planning, spatial
prioritization, and the enforcement of appropriate legislation. Here, we
introduce an open-access, online tool that maps the locations of these
most imperiled of species within South Africa. The Threatened Species
No-Go Mapping Tool’s primary objective is to inform the placement of
proposed potentially detrimental developments in order to encourage
early-stage Environmental Impact Assessment rejection or avoidance.
Furthermore, from an applied conservation viewpoint, the tool allows one
to assess the extent to which these No-Go Areas fall within the country’s
Protected Area network. We show how this information can be used to focus
conservation efforts and guide protected area expansion plans, ultimately
helping in safeguarding the most vulnerable species. Finally, we discuss
how the tool can be adapted and adopted in other regions/countries with
high levels of range-restricted, endemic species. Solution: By mapping the
distribution of the most range-restricted, threatened species, the
Threatened Species No-Go Mapping Tool informs the placement of proposed
potentially detrimental developments in order to encourage early-stage
Environmental Impact Assessment rejection or avoidance. As a result,
unnecessary cost to the developer and the responding interested and
affected parties can be avoided, ultimately reducing the irreversible loss
of critical habitat.
