Summary:

One of the forms of protection of the natural environment, according to the legal act from April 16, 2004, is an ecological site. This form has been used in Poland since 1991.
The main reason of creating ecological sites is a necessity to protect small-area objects which are valuable because of their environmental and landscape virtues and which due to their small area and minor importance are not protected by any other form, for example are not reserves (Koreleski 2004, Koreleski 2005, Sammel i in. 2012, Sajnóg, Wójcik 20).
This article shows chosen elements present in a process of registering and recording ecological sites. Based on the analysis of works cited and present for many years legal acts and procedures, it has been stated that there can be discrepancies between data of various registers, and especially in registers of forms of protection of the nature and The Land and Building Register (EGiB). These data are incoherent and incomplete.
The aim of the paper is to identify and show reasons for such a state and also its possible ramifications. Techniques of a qualitative analysis (of legal acts and regulations excising in the last 20 years) and descriptive analysis have been used in the research.
Discrepancies in an interpretation of a term of an ecological site itself (in various registers), depending on the major aim of creating it as well as incoherence and impreciseness of legal acts in the last 20 years and procedures of creating, registering and recording them, have been pointed out as main reasons of differences and defects. They should be treated as the basic reasons of differences in data and possible lack of some data in EGiB and in The National Register of Forms of Protection of The Nature (CRFOP). The paper also shows possible consequences of such a state and supports a necessity to use an interdisciplinary approach to solve this problem.
