Title Characteristics of Salt Plant Community and its Protection on the Area of Retrograde of Swina River Delta
Source Rocznik Ochrona Srodowiska
Abstract Scientific research was realized on the Karsiborska Kepa Island, which is one of the biggest islands laid in the retrograde delta of Swina river. Research was conducted on the meadow-pasture community area. After the preliminary analysis, grasslands located on the mineral-rot and mud-rot soils were chosen to the detailed analysis. They were conducted using botanical-weight method. Location of research sites is shown in Figure 1. Utility value of individual sward communities was determined on the basis of the utility (Lwu) - [8], and natural values by valorisation numbers (Lwp) - [13]. Configuration of ground water level was determined using piezometers, which were deployed in the area covered by the research (Fig. 1). In the term of first cut, on the allowed areas, plant samples were taken to the floristic botanical analyses. Use value of the grassland, was define by number of use value and natural value was define by number of valorization. Water level was detected by piezometres, which were located on the research areas. Differential environmental conditions influenced the community area. On the mineral-rot soil, community of: Agrostis stolonifera, Elymus repens with Festuca rubra, Agrostis stolonifera with Deschampsia caespitosa were formed. On the mud-rot soil with the higher level of groundwater, community of: Juncus gerardi and Festuca rubra with Juncus gerardi were formed. Little occurrence of salt plants (Juncus gerardi, Triglochin maritimum, Glaux maritime, Triglochin palustris, Plantago maritima and Lotus tenuis and Trifolium fragiferum) justified extensive pasture farming or mowing, which provided active environmental protection for salt plants, and also take notice on the necessary of efficient running of reclamation infrastructure. In order to maintain stability of humidity conditions on and the prevalence of communities of meadow-pasture with halophytes on Karsiborska Kepa it is necessary to improve functioning of the drainage infrastructure, with the possibility of regulation of groundwater level in various parts of the island and to stabilize agricultural use of grasslands by rational economy of grassland.
