Populations of the red-cockaded woodpecker (Picoides borealis) have experienced massive declines since European colonization of North America. This is due to extensive habitat loss and alteration. Logging of old-growth pine forests and alteration of the fire regime throughout the historic range of the species were the primary causes of population decline. Listing of the red-cockaded woodpecker under the Endangered Species Act of 1973, as amended, and increased emphasis on management of non-game species have resulted in efforts to recover remnant populations of the red-cockaded woodpecker in many parts of its historic range. Due to extensive research and adaptive management initiatives much is now known about the elements required for both short- and long-term management of viable populations of red-cockaded woodpeckers. A short-term strategy is crucial because currently available habitat, in nearly all populations, is poor in 1 or more critical respects. Consequently, almost all populations require immediate attention in the short term, to insure suitable midstory and understory conditions, adequate availability of suitable cavities, and restoration of demographic viability through improvements in number and distribution of breeding groups. Management techniques including artificial cavities, cavity entrance restrictors, translocation of birds, prescribed fire, and mechanical and chemical control of woody vegetation are available to achieve these needs. In the long term, cost-effective management of red-cockaded woodpecker populations requires a timber management program and prescribed fire regime that will produce and maintain the stand structure characteristic of high quality nesting and foraging habitat, so that additional intensive management specific to the woodpeckers is no longer necessary. Timber management that achieves this goal and still allows substantial timber harvest is feasible. The implementation of a red-cockaded woodpecker management strategy, as outlined above, represents appropriate ecosystem management in the fire-maintained pine ecosystems of the southeastern United States and will ultimately benefit a great number of additional species of plants and animals adapted to this ecosystem.

This is the book of abstracts for the Migration Conference 2020, 8 to 11 September. We’re pleased to welcome you to the 8th Migration Conference. The Migration Conference 2020 is held online via Microsoft Teams platform due to COVID-19 Pandemic restrictions. We have as usual covering a wide array of topics in this year’s edition too. There are about 350 presentations and debates running over 4 days from 8th to 11th September 2020. We have tried to address the time zone differences by moving sessions towards mid-day and grouping presentations, where possible, according to time zones. However, we believe this is not perfect to accommodate hundreds of colleagues from Brazil to Japan, and Australia to Canada. PLEASE NOTE all times are GMT+1 British Summer Time (BST). MS Teams will normally show the times according to your computers local time. Our all-women keynote speakers line up this year features Nissa Finney, Jelena Dzankic, Martina Cvajner, Elli Heikkila, Agnes Igoye, and Helén Nilsson. Although the main language of the conference is English, this year we will have linguistic diversity as usual and there will also be some sessions in Spanish and Turkish. We thank all participants, invited speakers and conference committees for their efforts and contribution. We are particularly grateful to hundreds of colleagues who served as reviewers and helped the selection process.
