Résumé

The Batyrevskaya colony of marmots located in territory of Chuvashia which remained in the depression years of the marmots' population presents a great interest for science. It was declared as an order in 1961, in 2000 was joined to the Prisurskiy nature reserve. There are true data about the marmots' number since the thirtieth of the last centw.y before 2005; 1931- seven fallilies, twenty-four dwelling holes (Teplov, Tikhvinskiy, 1936), 1961 - five marmots, one dwelling hole, in spring 1961 - ten between fifteen (Oliger, archives data), 1963- six marmots, eleven dwelling holes (Kulick et al, 1965), 1969- forty marmots (by data of the regional hunting specialist), 1970, 1971 - about fort y marmots (Khrustselevskiy, Sergeev, 1983), 1977 - forty-eight, 1978 - thirty-eight, 1979 - sixteen marmots (Dezhkin et al, 1983; Khrustselevskiy, 1988), 1979 - thirty marmots (by data of the regional hunting specialist), 1980 -twenty-two (by data of the region hunter; Dezhkin et al, 1983),1980 - sixteen (Lastukhin A.A., pers. comm.), 1981 - thirteen marmots (Khrustselevskiy, Sergeev, 1983; Khrustselevskiy, 1988),1981 - eight (data of the regional hunting specialist), 1982- output of the twenty marmots, brought froll the Ulyanovsk region; twenty-two marmots (Gurjev A.V., pers. comm.), thirty-three (data of the regional hunting specialist), eleven (Dezhkin, 1983,1985),1983 - twenty-three, 1984- twenty-eight, 1985- twenty, 1986- twenty, 1987- forty, 1988 - forty-two, 1989 - fifty-one (data of the regional hunting specialist), 1991 - sixty-three (nineteen fallilies), 1992 - forty (seven of the salle age) (data of the regional committee of the nature guarding), 1993- about fort y (eleven fallilies, thirty-one dwelling holes), 1994 - (eleven families, eighty-two dwelling holes), 1995 - fifty-four marmots, 1996- forty-eight, 1977- thirty-five, 1998- twenty-eight, 1999- twenty-two, 2000- twenty- eight (Dimitriev, 2001), 2001 - thirty-three (in spring), thirty-four (in autumn, allong them twenty-three young), 2002 - thirty-three (in spring), forty-seven (among them twenty-six young), 2003 - thirty (in spring), fifty-seven (in autumn, allong them twenty-six young), 2004 - forty-five in spring (in autumn fifty-seven, allong them ten young), 2005- forty-one (in spring). Received data testify that the marmots' colony functions rather stable in spite of its dislocation in the densely populated region. To keep this colony promoted the creation in this place in 1961 of the republic order, later in 2000 of the Batyrevskiy site of Prisyrskiy nature reserve, also historically turned out ecological and cultural relations between the marmots and the local population. This socio-ecological aspect, to our mind, presents a great scientific cognition and a practical interest.
