Plantings are commonly used in roadside reclamation for ornamental purposes and for increasing slope stability and road safety. However, the role of these plantings in restoring ecological processes, such as seed dispersal, has received little attention. We carried out a study to assess the potential role of plantings on roadside embankments to attract frugivorous birds and to enhance seed dispersal mediated by birds from the surrounding landscape. We examined: (1) bird species richness and abundance; (2) patterns of avian spatial distribution within embankments and (3) seed dispersal mediated by birds. Bird richness and abundance did not differ between embankments with and without plantings. However, birds were not distributed randomly within embankments, with levels of species richness and abundance for facultative frugivorous between 4.8–8 times higher in areas closer to plantings. An analysis of bird droppings showed that birds only dispersed seeds of the planted species since no seeds of woody plants from matrices were detected. These results suggest that plantings acted as selective bird attractors, providing food and perches for frugivorous species. Nevertheless, the scarcity of seed-dispersing birds in the surrounding agricultural landscape prevented plantings from enhancing seed dispersal and connectivity to adjacent habitat.

种植通常在路边的填海中用于装饰目的，并用于增加边坡稳定性和道路安全性。然而，这些种植在恢复种子散布等生态过程中的作用很少受到关注。我们进行了一项研究，以评估路堤上种植植物对吸引食肉类鸟类和增强周围环境鸟类传播的种子传播的潜在作用。我们研究了：（1）鸟类物种的丰富度和丰富度；（2）堤防中鸟类空间分布的模式，以及（3）鸟类介导的种子扩散。有和没有种植的路堤之间的鸟类丰富度和丰度没有差异。然而，鸟类并不是在河堤内随机分布的，其种类丰富和丰富的兼性节食水平介于4之间。靠近种植区的地区高8–8倍。对鸟粪的分析表明，鸟只分散了种植物种的种子，因为未检测到基质中的木本植物种子。这些结果表明，种植可作为选择性的鸟类吸引者，为食肉性物种提供食物和栖息地。然而，周围农业景观中种子散布鸟类的稀缺阻止了种植业促进种子散布以及与邻近生境的连通性。
