Amish and Amish Mennonite Genealogies
This encyclopedia for Amish genealogists is certainly the most definitive, comprehensive, and scholarly work on Amish genealogy that has ever been attempted. It is easy to understand why it required years of meticulous record-keeping to cover so many families (144 different surnames up to 1850). Covers all known Amish in the first settlements in America and shows their lineage for several generations. (955pp. index. hardcover. Pequea Bruderschaft Library, revised edition 2007.)
Retention as an Integrated Biodiversity Conservation Approach for Continuous-cover Forestry in Europe
Abstract: Retention forestry implies that biological legacies like dead and living trees are deliberately selected and retained beyond harvesting cycles to benefit biodiversity and ecosystem functioning. This model has been applied for several decades in even-aged, clearcutting (CC) systems but less so in uneven-aged, continuous-cover forestry (CCF). We provide an overview of retention in CCF in temperate regions of Europe, currently largely focused on habitat trees and dead wood. The relevance of current meta-analyses and many other studies on retention in CC is limited since they emphasize larger patches in open surroundings. Therefore, we reflect here on the ecological foundations and socio-economic frameworks of retention approaches in CCF, and highlight several areas with development potential for the future. Conclusions from this perspective paper, based on both research and current practice on several continents, although highlighting Europe, are also relevant to other temperate regions of the world using continuous-cover forest management approaches
Evaluating the Effectiveness of Retention Forestry to Enhance Biodiversity in Production Forests of Central Europe Using an Interdisciplinary, Multi-scale Approach
Abstract: Retention forestry, which retains a portion of the original stand at the time of harvesting to maintain continuity of structural and compositional diversity, has been originally developed to mitigate the impacts of clear-cutting. Retention of habitat trees and deadwood has since become common practice also in continuous-cover forests of Central Europe. While the use of retention in these forests is plausible, the evidence base for its application is lacking, trade-offs have not been quantified, it is not clear what support it receives from forest owners and other stakeholders and how it is best integrated into forest management practices.

Predicting Tree-related Microhabitats by Multisensor Close-range Remote Sensing Structural Parameters for an Efficient Selection of Retention Elements
Abstract: The retention of structural elements such as habitat trees in forests managed for timber production is essential for fulfilling the objectives of biodiversity conservation. This paper seeks to predict tree-related microhabitats (TreMs) by close-range remote sensing parameters. TreMs, such as cavities or crown deadwood, are an established tool to quantify the suitability of habitat trees for biodiversity conservation. The aim to predict TreMs based on remote sensing (RS) parameters is supposed to assist a more objective and efficient selection of retention elements. The RS parameters were collected by the use of terrestrial laser scanning as well as unmanned aerial vehicles structur...
