    Michael Bloom, a member of the Abingdon Naturalists Society, presents a thorough and detailed report on the orchid displays around the Hinksey Hill Interchange which have given pleasure to bus passengers travelling to and from Oxford and to passing motorists.
  2. Seventy eight insect species reared from fungi in an ancient, semi-natural beech woodland in the Chilterns

    published online February 2021
    Seventy eight species of non-coleopteran fungivorous insects were raised from fungi collected from an ancient, semi-natural beech wood in the southern Chiltern Hills near Henley. This allows matching the host fungus with the insect species that develop from them. Although many fungivorous insects are polyphagous, others are not, and we have identified food sources for a number of flies that have been known for many years as adults without determining the fungi from which they develop. These include: Exechiopsis leptura, raised from Botryobasidium aureum; Mycetophila autumnalis raised from the bracket Postia; M. lamellata from Ceriporiopsis; M. unipunctata from the resupinate Physisporinus; Tarnania nemoralis from Clitocybe, and Lasiomma seminitidum from rotting Meripilus giganteus. M. unipunctata had been known for more than 200 years without a host being identified. A brief discussion is given of conservation issues around fungivorous insects, in recognition of their importance in the woodland ecosystem.
  3. Is the population of ancient trees at Burnham Beeches sustainable?

    published online May 2021
    Burnham Beeches is designated as a nature reserve of European importance because of the ancient pollarded trees and their associated saproxylic species. Historical and recent surveys of the numbers of pollards have been used to calculate mortality rates and produce maps to indicate changes in live tree density over time. While the rate of loss has declined in recent years, likely due to intensive work on the trees, it is evident that fragmentation of the population is occurring as well as an overall decline in numbers. The consequences of this are discussed and some suggestions made for how to mitigate for the tree loss. The area of Burnham Beeches supporting the ancient pollards is relatively small. It would be beneficial to improve the management of adjacent areas in different ownership in order to buffer the nature reserve and provide suitable habitat for saproxylic species in the long term, given that saproxylic beetles in particular are, according to Cálix et al. (2018), the most threatened species group in Europe.
