Megjegyzések:	The authors present new faunistic data on dragonflies collected (larvae, exuviae and adults) and observed (adults) at four watercourses [two creeks (Csaronda, Kállai-főfolyás), one little river (Kraszna) and one medial river (Szamos)]. The investigated area (?Felső-Tisza-vidék`) is the geographical region of the northeast part of the Hungarian Great Plain. In the paper, the authors presented firstly the investigated area with the sampling sites, the methods used for the collection of specimens, the data processing and the introduced literature they had considered important in the identification of species and in reporting the faunistic data. Thereafter they provide a detailed material of the survey results from the sampling sites and finally summarize and evaluate the data based on the dragonfly fauna. Collections and observations were made in 1 year (2019), with the participation of 6 specialists on 24 days and 13 localities, in 11 cells (ET 69, EU 60, EU 61, EU 62, EU 92, EU 94, FT 09, FU 02, FU 03, FU 13, FU 20) of the 10x10 km UTM grid map. In the report, information on 757 specimens (451 males, 260 females, 46 specimens with undecided sex) is given in detail [318 larvae (142 males, 130 females, 46 with undecided sex), 11 exuviae (6 males, 9 females), 424 adults (303 males, 121 females)], with the observed adults representing 392 faunistic data (79 larvae, 15 exuviae, 236 collected and 66 observed adults) altogether. In this study, 29 species (10 Zygoptera and 19 Anisoptera) were recorded in the area. In the aspect of nationwide occurrence frequency 1 belongs to the very frequent, 13 to the frequent, 9 to the less frequent, 5 to the rare and 1 to the sporadic class.

Megjegyzések:	Based on our experiences from the survey of the occurrence characteristics of riverine dragonfly larvae, exuviae and adults, it can be concluded that data suitable for comparative evaluation and real monitoring can be obtained only that case, if the data collection criteria do not change throughout the whole period of the survey. Consequently we aimed to create a natural habitat survey method in a form of a data sheet that provides opportunity to record the habitat conditions of the watercourses on a given section and in a given time. Besides the sheet code and the eight basic criteria of the biotic investigation (topographical name, geo-coordinates and UTM codes of locality; time; collector and/or observer; taxon; aim and valuation of biotic examination and form and size of study site; methods of biotic field survey), the data sheet contains 30 main observation and examination standpoints (the defining and/or influencing background variables of the living beings' occurrence), equally paying attention to the special peculiarities of the bed in the case of the water-mass, the bottom and the riverside too, as well as the biotic and abiotic factors of the sampling site. Within the main viewpoints standardization was used that covers the whole range of the given background variables, and bases of this standardization - considering the measuring person's subjective decision situation - the types can be separated with sufficient clarity. In the case of some background variables - based on our field experience till now - such indicators were registered, that allow of judgement of the given type by the weight of it's occurrence. The filling in of the data sheet can be carried out in a short time even within field circumstances. Only the particle size composition analysis of the sediment, the determination of suspended load content and the ion type of the water, furthermore the trophic state identification of the water and sediment are suggested to implement in laboratory conditions. According to our experiences so far, the recommended data sheet provides solution to the unified recordings of the site conditions and field background variables of odonatological surveys on watercourses and in long term it is appropriate for the follow up and comparison of the spatial and temporal changes.
