Na \u0160umav\u011b k\u016frovci neodolalo mnoho vzrostl\u00fdch strom\u016f v hust\u00fdch porostech. Takov\u00e1to k\u016frovcov\u00e1 gradace dala vzniknout velkoplo\u0161n\u00fdm pasek\u00e1m, rozs\u00e1hlej\u0161\u00edm vyk\u00e1cen\u00fdm ploch\u00e1m a vzniku men\u0161\u00edch \u010di v\u011bt\u0161\u00edch ostrov\u016f bez strom\u016f.

N\u00e1sledn\u011b, po napaden\u00ed k\u016frovcem, se stromy za\u010daly postupn\u011b rozlamovat a upadat. D\u00edky tomu do\u0161lo k oslun\u011bn\u00ed ploch, to zp\u016fsobilo r\u016fst podrostu a rostlin, kter\u00e9 za\u010daly bohat\u011b plodit.\tZv\u011bt\u0161en\u00e1 plocha otev\u0159en\u00fdch prostor\u016f, zv\u011bt\u0161en\u00e1 nab\u00eddka bobulovit\u00e9 potravy a pravd\u011bpodobn\u011b i hmyzu p\u0159il\u00e1kalo v\u00edce ptactva.

Vzrostl po\u010det nov\u00fdch druh\u016f, kter\u00e9 ze \u0160umavy zmizely.
