Abstract

Savannas are an important ecotone between prairies and forests, and ants play a critical role in the success of these habitats. I studied how savanna restoration efforts influence ant diversity and the most efficient way to sample ants in restored savannas. Sampling 21 sites using pitfall traps and leaf-litter sifting, I found that pitfall traps collected significantly more species than litter sifting samples (41 and 21 species respectively). Ant diversity increased with restoration efforts. Older sites averaged twice as many species as younger sites, probably due to changes in habitat complexity. These results highlight the effect of temperate savanna restoration on ant diversity.
