Z t\u011bchto d\u016fvod\u016f p\u0159istoupila Spr\u00e1va N\u00e1rodn\u00edho parku \u0160umava v letech 2001\u20132004 k jeho revitalizaci. V t\u00e9 dob\u011b byla p\u0159ehrazena podstatn\u00e1 \u010d\u00e1st odvod\u0148ovac\u00edch kan\u00e1l\u016f a na povrch ra\u0161elini\u0161t\u011b navezen mul\u010d tak, aby se zde sn\u00e1z uchytily mok\u0159adn\u00ed rostliny.<\/p>\n

Ra\u0161elini\u0161t\u011b, kter\u00e9 bylo od t\u00e9 doby p\u0159\u00edstupn\u00e9 ve\u0159ejnosti, z\u00edsk\u00e1valo zp\u011bt sv\u00e9 funkce \u2013 op\u011bt za\u010dalo zadr\u017eovat vodu, ochlazovat krajinu a ukl\u00e1dat uhl\u00edk. N\u00e1v\u0161t\u011bvn\u00edci, kte\u0159\u00ed proch\u00e1zeli nau\u010dnou stezkou, tak mohli pozorovat tyto procesy p\u0159\u00edmo uvnit\u0159 tohoto seversk\u00e9ho biotopu a z nadhledu sledovat ra\u0161elini\u0161t\u011b z men\u0161\u00ed vyhl\u00eddkov\u00e9 v\u011b\u017ee. Zpo\u010d\u00e1tku p\u0159itom sta\u010dilo um\u00edstit na celou 1,5 km dlouhou nau\u010dnou stezku jen p\u00e1r pov\u00e1lkov\u00fdch chodn\u00edk\u016f, kter\u00e9 se klenuly pouze nad nejvlh\u010d\u00edmi m\u00edsty. Jak se ale ra\u0161elini\u0161t\u011b postupn\u011b regenerovalo a zavod\u0148ovalo, podzemn\u00ed voda stoupala a st\u00e1le zamok\u0159en\u00fdch m\u00edst rychle p\u0159ib\u00fdvalo. V sou\u010dasnosti je situace tak daleko, \u017ee nen\u00ed mo\u017en\u00e9 proj\u00edt nau\u010dnou stezku suchou nohou.<\/p>\n

\u201eTo je nekomfortn\u00ed pro turisty a z\u00e1rove\u0148 devastuj\u00edc\u00ed pro obnovuj\u00edc\u00ed se ra\u0161elini\u0161t\u011b. Proto Spr\u00e1va N\u00e1rodn\u00edho parku \u0160umava napl\u00e1novala kompletn\u00ed rekonstrukci, tedy sp\u00ed\u0161e stavbu plnohodnotn\u00e9ho pov\u00e1lkov\u00e9ho chodn\u00edku, kter\u00fd za\u010dnou \u0159emesln\u00edci budovat letos 1. srpna.

V\u00fdstavba pov\u00e1lkov\u00e9ho chodn\u00edku na Soumarsk\u00e9m ra\u0161elini\u0161ti vyjde na 4,5 milion\u016f korun bez DPH.
