Sustainable development goals imply proper landscape management, a challenging task in human-dominated environments, where the identification of key habitats is often necessary to achieve the conservation of multispecies communities or threatened taxa. We studied the avian composition of 9 habitats in Tota Lake, a highly diverse Andean wetland affected by human activities. We evaluated the richness, abundance, dominance, and bird diversity, and used a species-habitat network approach to assess some emerging properties of the landscape and to identify key habitats for conservation. We observed 116 bird species, with a low diversity index (Shannon = 2.2) due to the dominance of gregarious species. The landscape showed a substantial sensitivity to disturbances due to habitat loss. Natural habitats were more important than human-related habitats, except for the wooded pastures used for low-scale grazing, which are among the most important coverages. This habitat represented a good example of sustainable land use. In contrast, the croplands and touristic beach were notoriously unsustainable in terms of wildlife conservation. Among the natural habitats, the most important was the marshes that presented the higher richness, abundance, importance for the landscape network, and was the most used by birds of conservation concern. Natural forest habitats, despite being reduced and fragmented, were more important to birds than the extensive forest of introduced exotic vegetation, probably due to the evolutionary history of the birds with the native vegetation.

不同自然和人类相关栖息地对安第斯高湖鸟类保护的作用

可持续发展目标意味着适当的景观管理,这在人类主导的环境中是一项具有挑战性的任务,在这种环境中,通常需要确定关键栖息地,以实现对多物种群落或受威胁分类群的保护。我们研究了托塔湖中 9 个栖息地的鸟类组成,托塔湖是受人类活动影响的高度多样化的安第斯湿地。我们评估了丰富度、丰度、优势和鸟类多样性,并使用物种栖息地网络方法来评估景观的一些新兴特性并确定关键的保护栖息地。我们观察到 116 种鸟类,由于群居物种的优势,多样性指数较低(香农 = 2.2)。由于栖息地丧失,景观对干扰表现出极大的敏感性。自然栖息地比人类相关的栖息地更重要,除了用于小规模放牧的树木繁茂的牧场,这是最重要的覆盖范围。这个栖息地是可持续土地利用的一个很好的例子。相比之下,农田和旅游海滩在野生动物保护方面是出了名的不可持续。在自然栖息地中,最重要的是沼泽地,其对景观网络的丰富度、丰度和重要性更高,是受保护鸟类使用最多的地方。天然森林栖息地尽管减少和破碎,但对鸟类来说比引入外来植被的广阔森林更重要,这可能是由于鸟类与本地植被的进化历史。这个栖息地是可持续土地利用的一个很好的例子。相比之下,农田和旅游海滩在野生动物保护方面是出了名的不可持续。在自然栖息地中,最重要的是沼泽地,其对景观网络的丰富度、丰度和重要性更高,是受保护鸟类使用最多的地方。天然森林栖息地尽管减少和破碎,但对鸟类来说比引入外来植被的广阔森林更重要,这可能是由于鸟类与本地植被的进化历史。这个栖息地是可持续土地利用的一个很好的例子。相比之下,农田和旅游海滩在野生动物保护方面是出了名的不可持续。在自然栖息地中,最重要的是沼泽地,其对景观网络的丰富度、丰度和重要性更高,是受保护鸟类使用最多的地方。天然森林栖息地尽管减少和破碎,但对鸟类来说比引入外来植被的广阔森林更重要,这可能是由于鸟类与本地植被的进化历史。丰富,对景观网络的重要性,并且是保护关注的鸟类最常使用的。天然森林栖息地尽管减少和破碎,但对鸟类来说比引入外来植被的广阔森林更重要,这可能是由于鸟类与本地植被的进化历史。丰富,对景观网络的重要性,并且是保护关注的鸟类最常使用的。天然森林栖息地尽管减少和破碎,但对鸟类来说比引入外来植被的广阔森林更重要,这可能是由于鸟类与本地植被的进化历史。
