Wild pig (Sus scrofa) populations in Singapore have been rising over the past two decades, likely due to a lack of hunting or large natural predators to regulate their numbers, in addition to the availability of suitable habitats to expand into and possibly supplemental food from anthropogenic sources. In other nearby Asian forests, high densities of wild pigs have been shown to inhibit forest regeneration through seed predation, trampling, foraging for food (i.e., digging or rooting), creating wallows, and building birthing nests, which all may damage seedlings and saplings. Wild pigs may also facilitate the spread of invasive species by causing soil disturbances or acting as seed dispersers. Here we assessed the plants associated with pig foraging sites in Singapore along eight 6 m (W) × 1000 m (L) straightline transects in secondary forests. In contrast to many studies elsewhere, we found that wild pig foraging sites do not appear to be associated with any specific plant group or origin status (native or nonnative) within the secondary forests of Singapore. Our work is situated within secondary forests so that the knowledge gained can help inform Singapore's substantial reforestation efforts and specifically help to restore or protect habitats from wild pig degradation.
