Conservation Biologists around the world have a lot to learn from each other. Jonathan Choquette, Lead Biologist of the Ojibway Prairie Reptile Recovery program, focusing on saving an endangered population of Eastern Massasauga rattlesnakes in southern Ontario, recently traveled to Hungary to visit a similar project now in its 25th year. Of special interest to Jonathan was the technique the Hungarian team developed for conservation translocations of an endangered viper.
Just two weeks ago, in late August, I had the privilege of visiting the Hungarian Meadow Viper Conservation Centre, in the Kiskunság National Park of Hungary. What an amazing place! There is a very inspiring project going on there focusing on a special little creature, the Hungarian Meadow Viper (vipera ursinii rakosiensis).
I first learned about this work being conducted halfway across the world back in 2015, as I casually perused through a dusty booklet published by the International Union for the Conservation of Nature, which was neatly tucked away on the shelves of the WPC office in Guelph, Ontario. Since that time my curiosity was piqued, and I knew I wanted to visit the project and learn as much as I could.
Well 2018 was the year it finally happened, and I have some good news to report: the conservation project is still alive and well, and nearing its 25th year of operation! Way back in 1993 work began to assess the status of the remaining wild Meadow Vipers in Hungary. Roughly 10 years later, in response to a critical need to augment the wild population, a captive breeding centre was born.
Over the past 15 years, hundreds of baby vipers were born under the protective enclosures of the centre, and raised for 3-4 years prior to release. In addition to maintaining a healthy captive breeding colony of about 30 pairs of adult snakes, the team releases 2-3 dozen head-started snakes per year to suitable habitat nearby and across the country!
The one thing I was most interested in seeing was the technique they developed for conservation translocations: an artificial burrow design used at both the breeding centre and the release sites. The “burrow” consists of a segmented, chambered, clay pipe inserted into a wider plastic pipe (i.e., a “sleeve”) buried at a 30 degree angle into the ground. The artificial burrows, with the animals destined for translocation already inside, are simply slid out of the outer sleeve at the breeding centre and transported to the release location, where they are slid into a different outer sleeve at the site of release. A specially designed cap allows snake entry/exit of the burrow without getting stuck in the space between the burrow and outer sleeve. The snakes, being released in a familiar shelter, are free to make exploratory movements in their new territory and return the safety of their “home” burrow. Pretty amazing stuff!
And to top off an amazing visit, Tamás and Zita gave me an artificial burrow segment as a “souvenir”. This will come in very handy as a model to use on our conservation translocation work with Massasaugas at Ojibway Prairie. Well, I am thoroughly impressed and inspired by my visit to the Hungarian Meadow Viper Conservation Centre. But the story doesn’t end there! Our Hungarian colleagues have developed some short videos that highlight the key components of this conservation program: We are sharing these great videos on our YouTube channel! Be sure to check them out.
Thanks so much to Tamás and Zita for your time in showing us around the Centre, for answering my many questions, and for your inspiring conservation work!
