Willows ( " Salix atrocinerea " ) occupy the eastern part of the island in permanently or temporarily waterlogged soils as the only tree species, mono-specific forest, and on the west side are mixed with alder ( " Alnus glutinosa " ).

The riparian vegetation, consequently, thrives : specifically, the patches of European alder ( " Alnus glutinosa " ) and communities of Portuguese laurel ( " Prunus lusitanica " ), with the presence of European holly ( " Ilex aquifolium " ).

Curiously, Saunags is also home to great lime tree ( Niglini estate ) and group of great black alder ( " Alnus glutinosa " ) trees ( Kalnbunkas estate )-http : / / www . dabasretumi . lv / Raksti / GEnMelnalksni . htm ( in Latvian ).

In addition to the pine and the spruce, " Betula pendula ", " Betula pubescens ", " Populus tremula ", and " Alnus glutinosa " ( the latter along some creeks ) are the taller tree species encountered in the national park.

The nocturnal larvae are polyphagous, feeding on the leaves of a variety of woody and herbaceous plants, mainly Sorbus, " Quercus robur ", Salix, " Corylus avellana ", Stellaria, " Filipendula ulmaria ", " Alnus glutinosa ", Rubus and Populus.

The beetle and the beetle's larvae host on the grey or speckled alder ( " Alnus incana " ) and to a lesser extent black alder ( " Alnus glutinosa " ), but will be found on hazel, birch and / or hornbeam if there is a shortage of food.

It was described as new to science in 2014 by Clowez and colleagues, following collections from riparian forests in Spain under " Alnus glutinosa ", " Ulmus minor " and " Eucalyptus camaldulensis ", although previous collections from Turkey under " Pinus nigra " have also been reported.

Patches of wet woodland colonise former areas of cut-away and other low-lying areas close to the lake and are dominated by willows ( " Salix " spp . ), birch ( " Betula " sp . ) and alder ( " Alnus glutinosa " ) with patches of common reed also occurring.
19.
There is substantial canopy cover provided by maple sycamore ( " Acer pseudoplatanus " ) and European alder ( " Alnus glutinosa " ), which allows spawning by the resident population of Brown trout and migratory populations of sea trout ( " Salmo trutta " ) and Atlantic salmon ( " Salmo salar ")

Downy birch ( " Betula pubescens " ), common sallow ( " Salix caprea " ) and alder ( " Alnus glutinosa " ) grow on sections of the site, beneath which can be found the narrow-lipped helleborine ( " Epipactis leptochila " ), characteristic of metalliferous sites in Northumberland and uncommon elsewhere.
