.森林物种组成记录在82个森林中的希默兰和Hornsherred地区在丹麦和隔离（距离其他森林和森林地区），森林的连续性（老或年轻的200年），土壤pH值，树种组成和种子传播组进行了分析。连续性和隔离措施与森林物种丰富度在Hornsherred。Myrmecochorous，autochorous，anemoballistic和endozoochorous物种明显较少，在最近比古代森林。在希默兰，模式弱得多，很少有显着的相关性，发现森林物种丰富度或不同的种子传播组和森林的连续性或隔离。这两个地区之间的差异可能是由于土地利用不太密集，气候更潮湿，物种池较小，物种较少，距离较短的扩散在希默兰。因此，景观破碎化似乎限制了森林物种的退化更多的霍恩舍雷德比在希默兰。
. Forest species composition was recorded in 82 forests in the Himmerland and Hornsherred regions in Denmark and analysed with respect to isolation (distance to other forests and areas of forest), forest continuity (older or younger than 200 yr), soil pH, tree species composition and seed dispersal groups. Continuity and isolation measures were correlated with forest species richness in Hornsherred. Myrmecochorous, autochorous, anemoballistic and endozoochorous species were markedly fewer in recent than in ancient forests. In Himmerland, patterns were much weaker and few significant correlations were found between forest species richness or different seed dispersal groups and continuity or isolation of the forests. Differences between the two regions may result from less intensive land use, a more humid climate and a smaller species pool with less species with short distance dispersal in Himmerland. Landscape fragmentation therefore appears to limit forest species’recolonization more in Hornsherred than in Himmerland.
