Conservation of forest-dwelling arthropod species: simultaneous management of many small and heterogeneous risks

  • Author(s) / Creator(s)
  • The Canadian insect fauna is too inadequately Understood to support well-informed assessments about its conservation status: however, the foregoing collection of synthetic papers illustrates potential threats front industrial forestry. Loss of forest species and dramatic changes in forest insect assemblages driven by forestry activities are well illustrated by studies front places where industrial forest management has been more intensive or of longer duration. Improved Understanding of how arthropod species are coupled to habitats, especially microhabitats. appears to be central to progress toward their conservation. Studies of arthropods conducted at the species level are most relevant for applied conservation purposes. because only species-level work that is well documented with voucher specimens provides adequate comparative data to document faunal change. Although taxonomic infrastructure required to support such work is seriously under-resourced in Canada, entomologists can help themselves by producing useful modern resources for species identification, by Undertaking collaborative biodiversity work that minimizes the split between taxonomists and ecologists. and by supporting incentives for work at the species level. Securing the future of arthropod diversity ill Canadian forests through effective policy will require Sound regionally defined bases for whole-fauna conservation that mesh with broader land-Use planning. Building, these will require a practical Understanding of how \"ecosite-classification systems relate to arthropod diversity, accurate inventories of the predisturbance forest fauna in all regions, and development of sound monitoring plans designed to both detect faunal change efficiently and identify its drivers. such monitoring plans should include both baseline inventories and monitoring, of designated control areas. In addition, ef fective biomonitoring efforts will facilitate the development of suites of arthropod indicators, accommodate both seasonal (especially phenological) and annual variation, clarify the relationship between cost-effective samples and reality, and ensure adequate consideration of \"rare\" species. Return oil investment in monitoring, will depend Oil effective preplanned linkage to policy development that call respond to drivels of faunal change in a way that effectively addresses undesired changes.
