Near 45000 spider species are currently known throughout the world. They colonise almost all habitats - from subterranean environments to mountain tops. Spiders are a key component of forested habitats due to the fact that they are predators and they regulate invertebrate populations. Moreover, spiders constitute an important food source for other organisms. Many scientists claim that spiders are a good ecological bioindicators, which can monitor ecosystem change and help identify and address ecosystem stressors and guide forest management.

Fire is an important agent keeping a number of ecosystems in the native State and preventing their overgrowing by forest. Data of literatures suggested that spiders are first animals that can be found in the forest scene of fire. It is known that in a burned woods non web-building spiders are first noticed. Next, web-building spiders are observed, which dependent on the flora emergence. In the Upper Silesia Industrial Circle wooded areas can be find. The present of industrial and high ratę of population cause a lot of woods fire. So that is a reason why the Upper Silesia Industrial Circle seems to be a good choice of research about spiders in the after forest scene of fire. Preliminary studies present in a work seem to be confirm the literaturę data.
