In 1988\u20131992, a total of 4110 Tree Frog young, bred in the Zoo&#8217;s Laboratory of Ecology, were released into the wild in Bla\u017e\u0123a Ezers protected nature area. As a result, a healthy wild Eastern Tree Frog population was established in Southwestern Latvia. The reintroduction project was initiated and led by Juris Zvirgzds, Head of the Zoo&#8217;s Laboratory of Ecology. In 1997, Juris Zvirgzds received the award of the Cabinet of Ministers of the Republic of Latvia for his contribution to nature protection and conservation of biodiversity.<\/p>\n\n\n\n<p><strong>Publications<\/strong><\/p>\n\n\n\n<p><a href=\"https:\/\/rigazoo.lv\/wp-content\/uploads\/2023\/06\/AM_Hyla-arborea_litt_1995.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Zvirgzds J., Sta\u0161uls M., Viln\u012btis V. 1995.&nbsp;<strong>Reintroduction of the European Tree Frog<\/strong>&nbsp;(<em>Hyla arborea<\/em>)&nbsp;<strong>in Latvia.<\/strong>&nbsp;\u2013&nbsp;Memoranda Soc.
