General Site Description: 

URBAN RIPARIAL AND FLOODPLAIN FORESTS TRANSECT IN THE CITY OF LJUBLJANA The urban forest site consists of a riparian pine forest, floodplain hardwood forest and a meadow. The riparian pine forest is located in the sub-urban part of the city of Ljubljana, along the Sava river. It is positioned on a raised riverine terrace, outside of the direct influence of the river water. The site is located at 300 m above sea level, and consists of a 0.25 ha (50×50m) plot of Scots pine (Pinus sylvestris L.) in the upper canopy layer, with 78% of total growing stock and a mixture of deciduous tree species in the mid-story and lower canopy layer, such as small-leaved lime (Tilia cordata Mill.), sessile oak (Quercus petraea (Mattuschka) Liebl.) and European hornbeam (Carpinus betulus L.). The canopy cover is very loose (fragmented), containing rather dense shrub and forest floor vegetation. The bedrock material is glaciofluvial gravel and the soil was classified as Fluvisols (WRB 2007). The thickness of the O horizon was 0 to 6 cm and the depth of the M horizon is 0 and 40 cm, with a sandy loam texture. The floodplain hardwood forest is located in the vicinity of the riparian pine forest, approximately 2 m above the Sava River terrace during the daily high flow. The site is located at 296 m above sea level and consists of a 0.25 ha (50 × 50 m) plot of sycamore maple (Acer pseudoplatanus L.), gray alder (Alnus incana (L.) Moench.), small-leaved lime (Tilia cordata Mill.), European ash (Fraxinus excelsior L.), willows (Salix sp.), European black poplar (Populus nigra L.), etc. Canopy cover is loose, with rather dense shrub and forest floor vegetation. This site is especially exposed to spontaneous spreading of invasive alien plant species, e.g., Fallopia japonica, Solidago canadensis, Rudbeckia laciniata as a result of frequent flooding. Bedrock material is glaciofluvial gravel and the soil was classified as Fluvisols (WRB 2007). The thickness of the O horizon is 0 t to 4 cm and the depth of the M horizon was between 0 and 90 cm, with a clay-loam texture. There are ongoing measurements of bulk precipitation, throughfall, air temperature, air humidity, wind speed and direction, soil moisture and soil temperature, etc. In addition, water balance modelling for forest stands was performed. The north-east sub-urban part of the city of Ljubljana, along the Sava river.

Purpose of Site : 

The Gameljne urban forest site aims to study the living urban forests, to detect and monitor their changes, to understand and model underlying causes and mechanisms, and to use the knowledge to help preserving the biodiversity and associated ecosystem services. Special attention is given to hydrological cycle of these forests and how changes in their ecology influence their hydrological ecosystem services. Another important topic is the endangered natural regeneration of autochthonous black polar population and intense spontaneous spreading of invasive alien plant species along the riverbed.
