Description of the Area Surrounding the Biotope: The river in Lublin Voivodeship, which is the left tributary of the Bystrzyca river. It flows between the villages Zagórze and Krężnica. Then take a turn and heads east to the city of Bełżyce, in the village of Babin begins to meander strongly and help to create picturesque landscapes. The river is over 20km long and ends its course near Lublin, affecting the marshy area to the Bystrzyca river. Presented flooded area are the result of the beavers’ activities, they are surrounded by meadows, reed beds and fallen trees.
生物群落周边区域描述：这条河流位于卢布林省，是比斯奇察河的左支流。它流经扎古热和克伦日尼察两座村庄，随后转向东流至贝乌日采市，在巴宾村开始形成强烈蜿蜒的河道，造就了如画的风景。河流全长超过 20 公里，最终在卢布林附近汇入比斯奇察河的沼泽地带。眼前这片被淹没的区域是河狸活动的杰作，四周环绕着草地、芦苇丛和倒伏的树木。
Description of the Underwater Landscape of the Biotope: The bottom is covered with mud, and a small amount of plants and dead wood, creating excellent great environment for breeding fish. The only species I’ve seen is Gasterosteus aculeatus, Leucaspius delineatus, and Pseudorasbora parva, it is an invasive species and comes from Asia. For several years, permanently settled in Polish waters. The depth is small, about 20-50 cm, and the water temperature in the summer reaches even 28°C.
水下景观描述：河床覆盖着淤泥，散布着少量水生植物和枯木，为鱼类繁殖创造了绝佳环境。我仅观察到三种鱼类：三刺鱼、欧亚梅花鲈和麦穗鱼——其中麦穗鱼是来自亚洲的入侵物种，近些年来已在波兰水域永久定居。水深较浅，约 20-50 厘米，夏季水温最高可达 28°C。
Description of the Habitat Parameters: Turbid water, hardness about 20dH, pH is 7.5. Temperature in summer is 23-28°C, in winter the place completely freezes.

Threats to the Ecology of the Biotope: The river was severely polluted in the 1980s and 1990s, leading to the complete extinction of Astacus astacus and Pseudanodonta complanata. Unfortunately, all the time Krezniczanka is exposed to the negative impact caused by humans, littering or flushed fertilizers from nearby fields negatively affect this small ecosystem.
生物群落生态面临的威胁：该河流在 20 世纪 80 至 90 年代遭受严重污染，导致欧洲螯虾与扁蚌完全灭绝。不幸的是，克热尼昌卡河始终面临人类活动的负面影响——垃圾倾倒或周边农田冲刷的化肥持续侵蚀着这个脆弱的生态系统。
