Restoration plantings are frequently occupied by native wildlife, but little is known about how planting attributes influence breeding by, and persistence of, fauna populations. We monitored breeding success of woodland birds in restoration plantings in a fragmented agricultural landscape in south-eastern Australia. We documented nest fate and daily nest survival (DSR) in plantings and remnant woodland sites. We analysed the influence on breeding success of patch attributes (size, shape, type) compared to other potentially influential predictors such as nest-site and microhabitat variables. We found that, in general, patch attributes did not play a significant role in determining breeding success for woodland birds. However, we examined a subset of species of conservation concern, and found higher DSR for these species in restoration plantings than in similarly sized woodland remnants. We also found negative effects of patch size and linearity on DSR in species of conservation concern. The primary cause of nest failure was predation (91%). We used camera trap imagery to identify the most common nest predators in our study sites: native predatory bird species, and the introduced red fox (Vulpes vulpes). Our findings are further evidence of the value of restoration plantings and small habitat patches for bird populations in fragmented agricultural landscapes. We recommend controlling for foxes to maximise the likelihood that restoration plantings and other woodland patches in Australia support breeding populations of woodland birds. More broadly, our study highlights the importance of taking a detailed, population-oriented approach to understanding factors that influence habitat suitability for fauna of conservation concern.

植被和繁殖:农业景观中的恢复性种植是否支持林地鸟类的繁殖种群?

恢复性种植经常被本地野生动植物所占据,但是对于种植属性如何影响动物种群的繁殖和持久性知之甚少。我们在澳大利亚东南部一个零散的农业景观中监测了恢复种植中林地鸟类的繁殖成功。我们记录了在种植园和残余林地中巢的命运和每日的巢生存(DSR)。与其他可能影响的预测变量(如巢位和微栖息地变量)相比,我们分析了斑块属性(大小,形状,类型)对繁殖成功的影响。我们发现,一般而言,斑块属性在确定林地鸟类的繁殖成功率中不发挥重要作用。但是,我们检查了一部分受保护物种,并且发现这些物种在恢复种植中的DSR高于同等大小的林地残余物。我们还发现了保护区物种中斑块大小和线性度对DSR的负面影响。筑巢失败的主要原因是掠食(91%)。我们使用相机陷阱图像来确定研究地点中最常见的巢掠食者:本地掠食性鸟类和引入的赤狐(Vulpes vulpes)。我们的发现进一步证明了恢复种植和小的栖息地斑块对于零散的农业景观中鸟类的价值。我们建议控制狐狸,以最大程度地提高澳大利亚的恢复种植和其他林地斑块支持林地鸟类繁殖种群的可能性。更广泛地说,我们的研究强调了采取详细,
