Data from: Bark and ambrosia beetle catches differ with reported white oak decline, but pooled totals can mislead Tivon Feeley (24567798) Mark Runkel (24567915) Forest health and pathology Forest ecosystems Forestry management and environment Terrestrial ecology white oak decline, bark beetles ambrosia beetles Scolytinae forest health. forest monitoring Quercus alba indicator species analysis, Iowa <p dir="ltr">This dataset contains site-level bark and ambrosia beetle records and associated forest-condition measurements from 19 white oak-associated forest sites in Iowa sampled between 2022 and 2025. Seven sites were categorized as decline-reported and twelve as no-decline based on field assessments. The site-by-taxon matrix contains 32 taxa and 22,383 pooled captures. Supporting files provide site information, sampling coverage, taxon metadata, geographic coordinates, long-term climate normals, crown-thinning estimates, and lower-bole maternal-gallery measurements. Beetle counts represent pooled site catches; sampling years varied among sites, and counts are not standardized by trap operating time.</p> 2026-09-25T15:54:17Z Dataset Dataset 10.15482/USDA.ADC/33249888.v1 https://figshare.com/articles/dataset/Data_from_Bark_and_ambrosia_beetle_catches_differ_with_reported_white_oak_decline_but_pooled_totals_can_mislead/33249888 CC0
