Continued thread

for different reasons, wild #boar are also beneficial to the #forest #ecosystem, contrary to popular misconceptions. Here's an excerpt from an article by Chantal Lyons, "Rooting for the truth: on wild boar" - Lyons writes, "I suppose there are two layers to this. In terms of their #ecological role, they’re unique. The niche they occupy, and the ecological functions they perform, there are no other animals among British #fauna that do the things they do. For example, their #rooting; #badgers engage in some rooting behaviour, resembling mini boars at times. However, they don’t penetrate the soil as deeply, and their rooting is not as extensive.

There’s a term for it called ​#bioturbation: the act of going into the soil, breaking it open, and mixing the different layers, which impacts the nutrients and the microbial activity in the #soil. This also involves exposing the #seed bank and creating space for #wildflowers to germinate. There’s evidence that bioturbation enhances the soil in a way that makes it easier for #trees, such as #oaks, to germinate and grow.

Related to the rooting behaviour, wild boar are particularly effective at dispersing seeds and spores. They go all over the place, carrying these organisms in their fur and hooves, and even in their digestive systems, subsequently depositing them through excretion. Additionally, their wallowing activities create mini wetlands, providing valuable ephemeral pools that benefit other wildlife."
