Spiders suffer from human impact

so have a negative effect on spider diversity in agricultural and pasture ecosystems. The researchers show in the study that organic farming is more beneficial to arachnid abundance than conventional agriculture, but that these effects depend on the complexity of the landscape.

The study proposes some solutions for spider conservation. A reduction in mechanical alterations to the land, such as harvesting, ploughing and grazing would increase spider diversity in agricultural and pastural ecosystems. In addition, the use of insecticides should be more controlled, as in organic farming, and habitat fragmentation should be avoided.

According to the authors, although "they do not enjoy an excessive level of public sympathy", spiders are an important animal group for humans, since they free us of a large number of pest insects and are "very important" predators in the functioning of natural systems.
