在东北意大利是一个显着的洪泛平原河流，保留了动态的性质和形态的复杂性，必须具有大多数阿尔卑斯山河流在原始阶段的特点。这条河流系统，FiortizTagenento，不仅是阿尔卑斯山的参考点，而且是欧洲大型河流的生态系统模型，是一种宝贵的资源。塔霍托河有许多在河流生态学中没有得到适当考虑的属性：（i）一个超过150平方公里的巨大走廊，连接陆地和海洋以及两个生物群落，阿尔卑斯山和地中海;（ii）不受约束的洪泛区段，其特征是水生/陆生栖息地的动态镶嵌;（iii）大量植被岛屿（约100平方公里）。700）。我们认为，为了有效地参与河流保护和管理计划，了解这些濒危属性的功能作用至关重要。意大利的塔利亚门托河提供了难得的机会，可以以欧洲其他地方几乎无法研究的规模研究自然过程。
In NE Italy is a remarkable floodplain river that retains the dynamic nature and morphological complexity that must have characterized most Alpine rivers in the pristine stage. This river system, the Fiume Tagliamento, constitutes an invaluable resource not only as a reference site for the Alps, but as a model ecosystem for large European rivers. The Tagliamento has a number of attributes that have not been given due consideration in river ecology: (i) an immense corridor of more than 150 km2 that connects the land and the sea and two biomes, the Alps and the Mediterranean; (ii) unconstrained floodplain segments characterised by a dynamic mosaic of aquatic/terrestrial habitats; and (iii) a large number of vegetated islands (ca. 700). We believe it is critical to understand the functional roles of these endangered attributes in order to effectively engage in river conservation and management programmes. The Tagliamento River in Italy offers the rare opportunity to investigate natural processes at a scale that can be studied almost nowhere else in Europe.
