Redlisted beetles found in oak grove near Lake Østensjø

Data obtained from an insect survey of the oak grove in the ‘environmental park’ around Lake Østensjø (established 2002). “Østensjøvannets Venner” initiated the survey in 2014 to document the species diversity particularly in relation to a few large and potentially hollow oak trees. The aim of the survey was to identify which beetle species associated with dead wood exists in this area. Four insect traps (window traps) were put out at three different oak-tree locations, in the beginning of May to the end of August 2014. The traps were emptied every second week during this period. Sindre Ligaard identified the beetles. Totally 45 beetle species were found.

本数据集收录了来自位于 Østensjø 湖畔“环境公园”内橡树林（成立于2002年）的一次昆虫调查数据。‘Østensjøvannets Venner’组织于2014年启动该调查，旨在记录物种多样性，尤其是与几棵大型可能具有空洞的橡树相关的多样性。调查的目的是鉴定该区域存在的与枯木相关的甲虫物种。2014年五月初至八月底，在三个不同的橡树位置放置了四个昆虫陷阱（窗式陷阱）。在此期间，每隔两周清理一次陷阱。Sindre Ligaard 对捕获的甲虫进行了鉴定。共计发现了45种甲虫。
