The theme of this work is the monitoring of the snake´s head fritillary (Fritillaria meleagris L.) in the area of Međimurje County. Snake´s head fritillary is a threatened and strictly protected species in the Republic of Croatia and monitoring should be carried out continuously. Monitoring means assessing the status of taxa on natural locations, such as the Koprivnica-Križevci County, Varaždin County, Krapina-Zagorje County, Sisak-Moslavina County, Požega-Slavonia County, Bjelovar-Bilogora County and Zagreb County. Of course they are also widespread in the area of the Međimurje County in settlements such as Sveta Marija, Donji Vidovec and Goričan. The monitoring methodology includes field trips where the plants of snake´s head fritillary are counted and observed, filling the A3 forms for the assessment of population status, uses of GPS devices, searching for new surfaces in areas where snake´s head fritillary usually grow. Monitoring lasts for several days, and for Međimurje County it is an average of 3 work days in field and two researches that are involved in this activity, through which they are gathering all informations about snake´s head fritillary on locations that are mentioned above. After field work, the collected data are processed and compared to the results of previous years, when the activity of tracking snake´s head fritillary was also performed. During the monitoring in 2019 there was a significant decrease in the number of snake´s head fritillary, mostly attributable to weather conditions and reduced rainfalls in winter months. The absence of humid periods in the winter period 2018/2019 has significantly influenced the population of snake´s head fritillary in Međimurje County.
