Human disturbance to wildlife is on the rise and disturbance management is a key activity in conservation. Although disturbance can be controlled with relative ease in nature reserves that are properly resourced and managed by employed staff, most reserves do not fall into this category, and most wildlife exists outside managed reserves entirely. Thus, developing and demonstrating the effectiveness of simple, low-cost approaches to minimising disturbance is an important objective in conservation. In this study we examine the effectiveness of regulatory signs in controlling the behaviour and impacts of visitors on a colonial island-nesting bird, the Northern gannet (Morus bassanus), on an unmanaged island. First, we found that the percentage of successful nests declined with proximity to the disturbed edge of the colony, and was much higher in an undisturbed control area. Second, the number of birds displaced by visitors correlated negatively with the minimum visitor approach distance. Third, visitor proximity to the colony was dramatically reduced in the presence of a regulatory sign in comparison to periods without signs, which resulted in fewer birds being displaced from their nests. Photographers were the only visitor group who didn’t always comply with the sign. Our results show that breeding success in a species often thought to be well adapted to human presence, suffers from tourist pressure, and that simple and informative regulatory signs can be a cost-effective way of reducing the disturbance caused by visitors at unmanaged wildlife sites.

繁殖过程中调控标志在控制人类行为和北方塘鹅(Morus bassanus)干扰方面的有效性:一项实验测试

人类对野生动物的干扰正在增加,干扰管理是保护中的一项关键活动。虽然在由雇佣人员适当资源和管理的自然保护区中可以相对容易地控制干扰,但大多数保护区不属于这一类,并且大多数野生动物完全存在于管理保护区之外。因此,开发和证明简单、低成本的方法来最大限度地减少干扰的有效性是保护的一个重要目标。在这项研究中,我们研究了监管标志在控制游客对殖民地岛屿筑巢鸟类北部塘鹅 (Morus bassanus) 的行为和影响方面的有效性,该鸟类位于无人管理的岛屿上。首先,我们发现成功巢穴的百分比随着接近殖民地的扰动边缘而下降,并且在未受干扰的控制区域中要高得多。其次,被游客取代的鸟类数量与最小游客接近距离呈负相关。第三,与没有标志的时期相比,在有监管标志的情况下,游客与殖民地的距离大大减少,这导致从巢穴中流离失所的鸟类减少。摄影师是唯一不总是遵守标志的游客群体。我们的结果表明,通常被认为能够很好地适应人类存在的物种的繁殖成功会受到旅游压力的影响,并且简单且信息丰富的监管标志可以成为减少游客在不受管理的野生动物场所造成的干扰的一种经济有效的方式。被游客驱赶的鸟类数量与最小游客接近距离呈负相关。第三,与没有标志的时期相比,在有监管标志的情况下,游客与殖民地的距离大大减少,这导致从巢穴中流离失所的鸟类减少。摄影师是唯一不总是遵守标志的游客群体。我们的结果表明,通常被认为能够很好地适应人类存在的物种的繁殖成功会受到旅游压力的影响,并且简单且信息丰富的监管标志可以成为减少游客在不受管理的野生动物场所造成的干扰的一种经济有效的方式。被游客驱赶的鸟类数量与最小游客接近距离呈负相关。第三,与没有标志的时期相比,在有监管标志的情况下,游客与殖民地的距离大大减少,这导致从巢穴中流离失所的鸟类减少。摄影师是唯一不总是遵守标志的游客群体。我们的结果表明,通常被认为能够很好地适应人类存在的物种的繁殖成功会受到旅游压力的影响,并且简单且信息丰富的监管标志可以成为减少游客在不受管理的野生动物场所造成的干扰的一种经济有效的方式。这导致从巢穴中流离失所的鸟类减少了。摄影师是唯一不总是遵守标志的游客群体。我们的结果表明,通常被认为能够很好地适应人类存在的物种的繁殖成功会受到旅游压力的影响,并且简单且信息丰富的监管标志可以成为减少游客在不受管理的野生动物场所造成的干扰的一种经济有效的方式。这导致从巢穴中流离失所的鸟类减少了。摄影师是唯一不总是遵守标志的游客群体。我们的结果表明,通常被认为能够很好地适应人类存在的物种的繁殖成功会受到旅游压力的影响,并且简单且信息丰富的监管标志可以成为减少游客在不受管理的野生动物场所造成的干扰的一种经济有效的方式。
