Wildlife Research and Conservation


Collection of dead otters in the Czech Republic has occurred since 1990. From 2008, it has been organised by our company through various financial sources:

2008 - 2010: Project Finding missing data on biology and ecology of the Eurasian otter: creating a population development model

2011 - 2012: Nature Conservation Agency of the Czech Republic and own funds

2013 - 2014: Own funds

2015 - 04/2017: Project Implementation of selected measures from the care programme for the Eurasian otter in the Czech Republic

05/2017 - 2018: Nature Conservation Agency of the Czech Republic and own funds



We work with the following partners in collection and analysis:

Nature Conservation Agency of the Czech Republic - cooperation in collecting dead otters

Czech Otter Foundation Fund - cooperation in collecting dead otters (Třeboňsko)

Pavlov rescue station, o.p.s. - cooperation in collecting dead otters (Vysočina region)

Police of the Czech Republic - investigation of illegal killings of otters

Ústí nad Labem City Museum - basic autopsies, archiving samples

Institute of Vertebrate Biology, Academy of Sciences, Czech Republic - genetic analysis of samples

Czech University of Life Sciences, Prague and University of Veterinary and Pharmaceutical Sciences, Brno - parasitology

Faculty of Chemical Technology, University of Pardubice - inorganic substances in tissues

Project overview

Monitoring the status of endangered animal populations is usually based on assessing their distribution. However, systematic data on the deaths of individuals can also be a significant source of information. Finding the causes of wildlife mortality provides a valuable source of information about the factors affecting their populations. In addition to the causes of death, many important parameters of a given population can also be monitored by performing further analyses such as detailed autopsies, DNA analyses, X-rays, tooth cut, etc. These data can then be used to determine population age structure, sex ratio, mortality rate and genetic variability or gene flow. These data, especially if they are collected over a long period of time and by a consistent method, are an invaluable tool for monitoring the development of these populations.

Since the 1990s, dead otter collection for these reasons has occurred across the Czech Republic. From 2008, however, ALKA Wildlife o.p.s. has taken on this responsibility. This is our long-term goal and we aim to deal with this topic in more detail in the future.
