A frog chorus on summer evenings
KwaZulu-Natal’s Zululand region has the highest frog diversity in the province. At Suni-Ridge, much of it on habitat restored from old farmland, more than 50 species have been recorded — and on summer nights their calls serenade the restaurant deck.
Restored habitat, rich diversity and the value of long-term monitoring
Suni-Ridge has been documenting its amphibian species for several years, providing important habitat — much of it restored from monoculture agriculture — to the benefit of frogs. The Zululand region boasts the highest frog species richness in the province thanks to its rich diversity of habitats, high rainfall and warm temperatures.
Keeping annual records of which species are detected provides valuable monitoring information, helping to explain changes in species assemblages over time in response to climate or habitat change. One of the best ways to do this is through call identification — each species has its own unique call. So sit back and enjoy the sound of the frogs serenading you from the restaurant deck on summer evenings.
Keeping annual records of which species are detected provides important monitoring information, and can help explain changes in species assemblages over time in response to climatic conditions or habitat change.
