- Description:
- The decline in groundwater levels is a cause of concern in many regions of the world, including the Sand Ridge of Hungary. The causes of the regional depletion range from rising air temperatures, changes in precipitation, domestic and agricultural groundwater use and past amelioration and recent afforestation, including the effects of drilling for crude oil exploration. The relations between the decline, the soil water regime and groundwater recharge under existing aged forests remained unclear thus far. Based on our monitoring of groundwater and soil moisture we aim to clarify this interplay in a new experimental site on the hilltop of the Sand Ridge. We compared three land-uses: a 41-year-old black locust (Robinia Pseudoacacia) offshoot forest, an 83-year-old first generation black pine (Pinus nigra) forest, and a grassland control site. The observed differences in the soil moisture profiles and dynamics were connected to the use of water by the given type of vegetation. We indicated a connection between the disruption of the groundwater recharge and the loss of contact of the rooting system of the forests with the deepening of the unconfined aquifer. Even if the aged forests could locally contribute to the decline, we conclude that the decline at the hilltop site that may be more strongly driven by other regional factors.

- Description:
- Středoevropská lesní měkkýší fauna je přirozeně velmi bohatá díky poloze na zoogeografické křižovatce Evropy. Dnes ale padá za oběť nevhodnému lesnímu hospodářství. První velkoplošná devastace přirozených lesních společenstev byla způsobena výsadou borových a především smrkových plantáží během konce 19. století. V takových plantážích dnes žije 3-5 druhů plžů. Tuto devastaci měkkýší i další bezobratlé fauny pak dovršily výsadby akátů na špatně dostupných místech zarostlých bohatou stepní vegetací, především v kaňonech velkých řek. Rekonstrukce složení původní lesní fauny na většině území České republiky je proto dnes velmi komplikovaná a jsme tak závislí na svědectví fosilních měkkýších sukcesí., Regional woodland mollusc fauna is falling victim to unsuitable forest management. The first important large-area devastation of natural forests was caused by pine and mainly spruce plantations (from the end of the 19th century), with 3-5 mollusc species. Locust tree planting in reserved sites with rich steppe vegetation subsequently finished the devastation of invertebrate fauna especially in canyon areas of large rivers. The reconstruction of the composition of native mollusc forest fauna in the majority of areas of the Czech Republic is complicated and depends on the evidence of fossil mollusc successions., and Vojen Ložek, Lucie Juřičková.
