New assessment finds lack of knowledge when designating MPAs lets ecologically important species slip through the net — and that small,有针对性的改变可以影响保护区的效率

— By Freya Wilson,万博亚洲体育前沿科学作家

Current marine protected areas (MPAs) leave almost three-quarters of ecologically and functionally important species unprotected,结论新的芬兰MPA网络的性能评估。发表在万博亚洲体育海洋科学前沿,the study finds the MPAs were designated with little knowledge of local marine生物多样性,提高现有网络生态最相关的地区只有1%可以翻倍保护最重要的物种。除了识别领域的高保护价值,the methodology — which uses a unique new dataset of 140,000个样本,也可以用于避免基于生态系统的海洋空间规划和影响,manbetx 手机客户端包括风力能源基础设施的选址,水产养殖和其他人类活动。

Marineecosystems正面临前所未有的生物多样性的丧失栖息地的破坏,海洋环境变化和增加提取海洋资源。

”This means now,more than ever,对于维持海洋生态系统保护区是至关重要的,”说Elina Virtanen,该研究的第一作者从芬兰环境研究所(SYKE),芬兰。

Marine Protected Areas — which can encompass estuaries,海洋和海洋,保护这些自然资源与人类活动。在欧洲,欧盟成员国使用欧盟栖地指令指定保护区基于列表的栖息地和物种保护方面起到了重要作用。

In Finland,which has one of the most complex marine environments worldwide,目前大约10%的海洋保护。But the assessment of Finnish MPA efficiency reveals this has still left important parts of the ecosystem completely unprotected — with an average of only 27% of marine biodiversity currently protected.

那么这是怎么发生的?吗?

”Establishment of these protected sites has relied on certain important habitats,such as lagoons,浅海湾和珊瑚礁,or the presence of seals or important bird areas,rather than knowledge of underwater species present or the ecological value of those areas,”维尔塔宁解释道。

虽然当前海洋保护区用来保护许多重要的栖息地,他们给的太少考虑水下自然,特别是功能重要的物种。但是由于广泛的保护覆盖在芬兰海域已经实现,明确证据需要任何更改现有的海洋保护区。

”因此重要指示的领域是最重要的海洋生物多样性热点地区,”维尔塔宁说。

研究人员有近140,000最近收集的样本数据对物种和栖息地的分布,as well as data on human pressures and the marine environment.These data were input into ecological distribution models to get a comprehensive view of the current marine environment.

这些分布模型被应用于空间优先级技术分带,which grades areas based on their ecological importance.这可以用来识别领域的高保护价值。

”我们发现增加保护区生物多样性最丰富地区仅为10%至11%将使最重要的生态系统物种的保护,”维尔塔宁说。”This means increased protection of rare and threatened species,功能重要的物种和鱼类繁殖区域。””

However,研究人员强调,增加保护区不是唯一手段维护海洋生态系统的完整性。Human activities threatening biodiversity can also be reallocated to areas of low biodiversity and conservation value using ecosystem-based marine spatial planning.

”We felt it is also important to highlight where sea usage can be allowed,such as the extraction of seabed materials,水产养殖、or wind energy,”维尔塔宁说。

This means a big win for marine protection,以及一个具有成本效益的MPA指定方法可以让决策者高兴。

Provided sufficient data exist,the approach can be used globally to show that small but targeted changes can have massive effects on the efficiency of protected areas — and a major boost for sustainable use of the sea.

”有必要重新评估当前MPA边界,以确保他们重点保护工作最有价值的地区,和强调增加生态效率是至关重要的指定或扩大海洋保护区时,”维尔塔宁说。”这样我们可以确保海洋保护区实现全球环境保护目标有意义和有效的”。”
