Upiniai bebrai (lot. Castor fiber) yra vieni aktyviausi\u0173 \u201eekosistem\u0173 in\u017einieri\u0173\u201c. Jie geba i\u0161 esm\u0117s pakeisti aplink\u0105: statyti u\u017etvankas, formuoti \u0161lapynes ir reguliuoti vandens lyg\u012f.

Art\u0117jant jaunikli\u0173 atsivedimo laikotarpiui, bebrai aktyviai tvarko savo gyvenam\u0105j\u0105 teritorij\u0105. Jie stiprina ir remontuoja b\u016bstus, stabilizuoja vandens lyg\u012f, kaupia maisto atsargas. \u0160iuo laikotarpiu ypa\u010d suintensyv\u0117ja statybiniai darbai \u2013 bebrai stato ar atnaujina u\u017etvankas, kasa kanalus, gilina vandens telkinius.<\/p>

Kad palaikyt\u0173 auk\u0161t\u0105 vandens lyg\u012f, bebrai naudoja \u012fvairi\u0105 med\u017eiag\u0105 \u2013 ne tik nukritusias \u0161akas, bet ir aktyviai ver\u010dia pakran\u010di\u0173 med\u017eius, nugrau\u017eia kr\u016bmus. D\u0117l to nuken\u010dia jauni medynai, pakran\u010di\u0173 augalija, kei\u010diasi kra\u0161tovaizdis.<\/p>

Apgrau\u017eti ir i\u0161vartyti med\u017eiai \u2013 ne vienintel\u0117 bebr\u0173 daroma \u017eala. Did\u017eiausi\u0105 problem\u0105 grau\u017eikai kelia vandens re\u017eimui. J\u0173 \u012frengtos u\u017etvankos pakelia vandens lyg\u012f ir u\u017elieja aplinkines teritorijas \u2013 mi\u0161kus, pievas, \u017eem\u0117s \u016bkio laukus. U\u017emirkusios teritorijos tampa netinkamos \u016bkininkavimui, \u017e\u016bsta med\u017eiai, kr\u016bmai ir augalai. Arba atvirk\u0161\u010diai \u2013 pakeitus hidrologiniam re\u017eimui, tikslin\u0117s med\u017ei\u0173 r\u016b\u0161ys, tokios kaip egl\u0117s, pu\u0161ys ir kt. med\u017eiai, pradeda d\u017ei\u016bti.<\/p>

Ypa\u010d da\u017enai bebrai \u012fsikuria melioracijos grioviuose ir kanaluose \u2013 vietose, kurios buvo \u012frengtos pertekliniam vandeniui nutek\u0117ti. U\u017etvenk\u0119 tokius griovius, \u0161ie gyv\u016bnai suardo melioracijos kanalus, pablogina drena\u017eo sistem\u0173 darb\u0105, tokiu b\u016bdu panaikindami melioracijos sistemos paskirt\u012f ir sukeldami pakartotin\u012f teritorij\u0173 u\u017emirkim\u0105.<\/p>

Vis d\u0117lto bebr\u0173 veikla n\u0117ra vien neigiama. Ten, kur ji nesikerta su \u017emogaus interesais, bebrai atlieka svarb\u0173 ekologin\u012f vaidmen\u012f \u2013 kuria \u0161lapynes, didina biologin\u0119 \u012fvairov\u0119, sudaro s\u0105lygas daugeliui kit\u0173 r\u016b\u0161i\u0173 veistis. J\u0173 suformuotos buvein\u0117s tampa prieglobs\u010diu pauk\u0161\u010diams, varliagyviams ir vabzd\u017eiams, ypa\u010d sausr\u0173 metu, nes bebraviet\u0117se laukiniai gyv\u016bnai randa taip b\u016btino vandens.<\/p>

Siekiant suma\u017einti bebr\u0173 darom\u0105 \u017eal\u0105 ir palaikyti subalansuot\u0105 populiacij\u0105, Lietuvoje taikomas j\u0173 gausos reguliavimas. Bebrai yra med\u017eiojami nustatytu sezonu \u2013 nuo rugpj\u016b\u010dio 1 d. iki baland\u017eio 15 d. Med\u017eiokl\u0117 nevykdoma jaunikli\u0173 gimimo ir auginimo laikotarpiu, siekiant u\u017etikrinti gyv\u016bn\u0173 gerov\u0119 ir populiacijos stabilum\u0105.<\/p>

Bebrai gyvena \u0161eimomis \u2013 paprastai pora kasmet susilaukia 2\u20134 jaunikli\u0173. Kadangi \u0161ie gyv\u016bnai gali gyventi apie 10\u201312 met\u0173, per gyvenim\u0105 viena pora gali susilaukti keliasde\u0161imties palikuoni\u0173. Ma\u017edaug dvej\u0173 met\u0173 am\u017eiaus jaunikliai palieka \u0161eim\u0105 ir pradeda savaranki\u0161k\u0105 gyvenim\u0105, ie\u0161kodami nauj\u0173 teritorij\u0173. Taip bebr\u0173 arealas ple\u010diasi, o kartu did\u0117ja ir j\u0173 daroma \u012ftaka aplinkai.<\/p>

Pagal med\u017eiokl\u0117s plot\u0173 naudotoj\u0173 apskaitas Lietuvoje registruojama apie 40\u201350 t\u016bkst. bebr\u0173, ta\u010diau realus skai\u010dius gali b\u016bti didesnis, nes dalis populiacijos n\u0117ra tiksliai apskaitoma. D\u0117l to bebr\u0173 gausa vertinama kaip stabili, ta\u010diau reikalaujanti nuolatinio steb\u0117jimo ir reguliavimo.<\/p>

U\u017e \u0161i\u0173 grau\u017eik\u0173 populiacijos gausos reguliavim\u0105 yra atsakingi med\u017eiotojai, med\u017eiojantys tuose med\u017eiokl\u0117s plot\u0173 vienetuose, kur bebr\u0173 daroma \u017eala keli\u0105 pavoj\u0173 aplinkai. Na, o bebr\u0173 apgrau\u017etus med\u017eius ir i\u0161vartas tvarko VMU mi\u0161kininkai.<\/p>","protected":false},"excerpt":{"rendered":"
