Results focused on the crayfish protection

Great deal of the project activities focused on raising of public awareness in the crayfish protection. Within this activity a thematic calendar was produced as well as a leafleat aimed at protecting our native crayfish.

Leaflet “Crayfish in the Czech republic - what is allowed, what is not, what to do, what not to do”

The leaflet focuses on protection of our native crayfish populations. It summarizes the basic information on the crayfish in the Czech republic and highlights the basic rules for the native species protection.

Calendar promoting the crayfish protection (2016)

One of the project activities focused on crayfish protection promoting was the creation and distribution of the thematic calendar. Calendar for the year 2016 was printed in an edition of 2,000 copies and the prints were distributed during the educational activities to the interested participants from the expert as well as the general public.

Information boards

An important educational outcome of the project was the realization of a total of 36 information boards. Their aim is to give information on our native crayfish species protection and on the risk of the dissemination of the invasive species particularly in relation to the occurence of the crayfish plague. The information boards were located at localities of European relevance (26 boards) and other places with crayfish occurence (10 boards).

Monitoring results - summary

During the project a large amount of data was assembled and assessed, including the data on pharmaceuticals and pesticides content in water, the data on presence of the substances in sediments and data on presence and accumulation of organic substances and metals in crayfish bodies. For relevant monitoring sites/localities the charts from the following overview are also available under the “data” tab together with further data and context information.

Results of monitoring - localities, data

Besides above mentioned results a large amount of data was measured, processed and assessed on the total of 110 localities. On that localities infrmation was obtained on observed species and number of crayfish and fish, presence of pollutants in water, sediment and crayfish tissues, information on composition of macrozoobenthos, on hydromorfology etc. Results of the assessement were published in an interactive map with related data (tabular, photos, charts) and could be found together with other contextual information under the “data” tab.
