Research: “Saboteur” wild boar plays an important role in maintaining rainforest diversity

“We have shown that wild boars can support a higher diversity of ecosystems, and because of the beneficial effects of their nesting, they are no longer just annoying Harmful organisms,” Luskin Bo said.

“Before production, wild boars usually build farrowing houses consisting of hundreds of saplings in flat and dry places in the forest. Although many dominant saplings are killed during nesting, the local dominance is inadvertently reduced The number of tree species, but usually does not reduce the rare native tree species, thus supporting the diversity of trees.”

Dr. Luskin pointed out that wild boar (Sus scrofa) is the offspring of the same domestic pig. Usually regarded as harmful animals by farmers, land managers and natural resource protectors. “Their negative effects on nature and cultivated ecosystems have been fully demonstrated-from destroying the soil to attacking newborn livestock.”

This is the first link between animals and the key mechanism for maintaining rainforest diversity Research up.

This group of scientists marked more than 30,000 saplings in a rainforest in Malaysia. After collecting more than 1,800 saplings from more than 200 pig litters, they inspected the trees in the pig’s nesting area. How diversity changes.

“You can think of pigs as’accidental forest gardeners’, they prune ordinary seedlings and inadvertently maintain diversity,” said Dr. Luskin. “In many areas, people focus on management The excess number of live pigs is to limit their negative impact on the environment. However, our research results indicate that keeping pigs in the ecosystem may have some positive effects.”

Dr. Luskin pointed out that due to field investigations It was carried out in Malaysia, and the pigs there are native, so Australian invasive pigs may not have a similar impact. “We are currently designing a new research method to study the same pig production method in Queensland.”

“This is an interesting discovery, because pigs have become the most widely distributed large animals on the planet. So recording any new ecological impact will have a huge impact on the world,” said Dr. Luskin.
