\u201eNa z\u00e1klad\u011b t\u011bchto v\u00fdsledk\u016f jsme u\u017e v roce 2015 zah\u00e1jili vlastn\u00ed, podrobn\u011bj\u0161\u00ed monitoring s c\u00edlem zjistit detailn\u011bj\u0161\u00ed v\u00fdvoj roz\u0161\u00ed\u0159en\u00ed vydry na \u00fazem\u00ed n\u00e1rodn\u00edho parku a chr\u00e1n\u011bn\u00e9 krajinn\u00e9 oblasti \u0160umava,\u201c<\/em> dod\u00e1v\u00e1 Jan Mokr\u00fd.<\/p>\n

V roce 2015 zoologov\u00e9 roz\u010dlenili \u0160umavu do 86 \u010dtverc\u016f o rozloze 6×5,6 km. V ka\u017ed\u00e9m \u010dtverci vybrali dva mosty p\u0159ekon\u00e1vaj\u00edc\u00ed \u0159eku nebo potok, pod kter\u00fdmi panovaly vhodn\u00e9 podm\u00ednky pro zna\u010dkov\u00e1n\u00ed vyder. Tyto vybran\u00e9 mosty se tak staly kl\u00ed\u010dovou sou\u010d\u00e1st\u00ed monitoringu.<\/p>\n

\u201eVydra pat\u0159\u00ed mezi teritori\u00e1ln\u00ed druhy, a sv\u00e9 teritorium si zna\u010d\u00ed mimo jin\u00e9 trusem.

V takov\u00e9m p\u0159\u00edpad\u011b je relativn\u011b snadn\u00e9 potvrdit p\u0159\u00edtomnost tohoto \u00fa\u017easn\u00e9ho \u017eivo\u010dicha v dan\u00e9 lokalit\u011b.

Od roku 2015 se d\u00edky tomuto sledov\u00e1n\u00ed potvrdilo, \u017ee v\u00fdskyt vydry \u0159\u00ed\u010dn\u00ed je stabiln\u00ed ve v\u011bt\u0161in\u011b \u00fazem\u00ed NP a CHKO \u0160umava.

V\u011bt\u0161ina z nich je obsazena ka\u017edoro\u010dn\u011b, n\u011bkter\u00e9 lokality se v obsazenosti st\u0159\u00eddaj\u00ed.

Ale tady se nen\u00ed co divit: kysel\u00e1 a drav\u00e1 voda s mnoha vysok\u00fdmi skaln\u00edmi stupni nen\u00ed p\u0159\u00edzniv\u00e1 ani pro \u017eivot pstruh\u016f, kte\u0159\u00ed tvo\u0159\u00ed podstatnou slo\u017eku j\u00eddeln\u00ed\u010dku vydry.<\/p>\n

\u201eV\u00fdsledky tohoto dlouhodob\u00e9ho monitoringu n\u00e1m jasn\u011b \u0159\u00edkaj\u00ed, \u017ee vyd\u0159e \u0159\u00ed\u010dn\u00ed se na \u0160umav\u011b da\u0159\u00ed. N\u00e1\u0161 monitoring sice v tuto chv\u00edli neumo\u017e\u0148uje stanovit jej\u00ed po\u010detnost, ale odhadujeme, \u017ee jich zde \u017eij\u00ed des\u00edtky.
