Mechanical management decreases arthropod biomass by changing vegetation structure in fallow fields of high conservation value

Datasets collected in fallow lands in the agricultural lands within the Lleida plain (Catalonia, north-eastern Spain) on 2022-2023. These data is analyzed in the research article: Mechanical management decreases arthropod biomass by changing vegetation structure in fallow fields of high conservation value (on press). See the article for further information on experimental design and data collection.

Datasets incude:

• Biomass: arthropod abundance data, collected with pitfall traps, classified by order and converted to biomass values
• Orthoptera: orthoptera counts from transects. Classified by body size
• Pollinators: pollinators counts from transects. Classified by group, family and genre
• Vegetation: all previous datasets include data from vegetation structure associated to the pitfall station or transect
