Existing global databases on biodiversity responses to land use generally distinguish only broad land use types, focus on a wide taxonomic coverage at the expense of detail or completeness, or do not include biodiversity in primary vegetation as a benchmark. Here, we introduce <i>DiVert</i>: a comprehensive global dataset with local measurements of vertebrate abundance and diversity in a variety of land types and management practices as compared to primary vegetation.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main Types of Variables Contained</h3>\u0000 \u0000 <p>The database contains 5702 diversity and 177,340 abundance values in seven main land types: agroforestry, cropland, forestry, pasture, urban, secondary vegetation and primary vegetation. For each record, we also report detailed information relevant for assessing impacts of land use and management on vertebrate abundance and diversity. This information includes prior land use, time since conversion, crop type and diversity, type of logging and the presence of natural margins.
