Spider specimen data from Satoyama landscapes, including abandoned farmland, collected over multiple periods in Machida City, Tokyo

Satoyama is a traditional heterogeneous Japanese landscape complex including semi-natural ecosystems such as farmland, grassland, and secondary forests. In Satoyama, abandonment of farmland is increasing, contributing to the mosaic structure of these landscapes by introducing new components. However, previous research on Satoyama has largely overlooked this perspective. Spiders serve as valuable biodiversity indicators in mosaic landscapes and provide ecosystem services, such as pest control. This study presents spider collection data as an indicator of abandoned farmland’s impact on surrounding biodiversity, considering it a factor in enhancing landscape mosaic complexity. Specimens were collected from different Satoyama landscape components, including dry fields, paddy fields, abandoned dry fields, and abandoned paddy fields, in Machida City, Tokyo, over four periods during June–October 2023. The resulting dataset included 629 individuals representing 94 taxa identified at the following levels: 55 species, 31 genera, 1 subfamily, and 7 families.
