Long periods of drought and mild winters have significantly affected the forests of the Czech Republic in recent years. If this trend continues, forest stands will be weakened and dehydrated, which will increase the probability that forest fires will occur and spread. It is essential that fire managers prepare for this possibility. A main requirement for extinguishing large forest fires is the availability of water supply points. In this study, we determined if the Czech Republic has enough water to fight forest fires and whether these water supply points are distributed so that all forest stands will have enough water nearby to fight fires. We analysed forests, water supply points and forest roads in three study areas. One reservoir is sufficient to cover tens to hundreds of hectares of forest. We found that there are currently enough water supply points in the studied areas of the Czech Republic to extinguish forest fires. The results indicate that any shortage in water availability can be eliminated by using water supply points that are useable but that are not currently part of the database used by Fire Rescue Service of the Czech Republic. A thorough and regular update of the database of water supply points is therefore essential.

近年来，长期干旱和冬季温和严重影响了捷克共和国的森林。如果这种趋势持续下去，林分将被削弱和脱水，这将增加森林大火发生和蔓延的可能性。消防经理必须为这种可能性做好准备。扑灭大面积森林大火的主要要求是供水点的可用性。在这项研究中，我们确定了捷克共和国是否有足够的水来扑灭森林大火，以及是否分配了这些供水点，以便所有林分站附近都有足够的水来扑灭森林大火。我们分析了三个研究区域的森林，供水点和林道。一个水库足以覆盖数十至数百公顷的森林。我们发现，捷克共和国研究的地区目前有足够的供水点来扑灭森林大火。结果表明，可以通过使用可用的供水点来消除任何水资源短缺，但是这些供水点目前不属于捷克共和国消防服务所使用的数据库。因此，必须定期对供水点数据库进行彻底更新。
