Tvar krajiny je formovana rickou Rokytnou, ktera zde tvori cetne
meandry. Relief krajiny je diky tomu znacne clenity. V uzemi je
mozne nalezt svahy nejruznejsi orientace a sklonu, cetne skalni
vychozy a kolme skalni steny, coz v kombinaci s ruznym chemismem
pudy vytvari podminky pro vznik rady odlisnych rostlinnych
spolecenstev. Podklad je tvoren slepenci permskeho stari (tzv.
rokytenske slepence). Misty jsou permske sedimenty prekryty
sedimenty kvarteru, caste jsou mlade (holocenni) ricni sedimenty.
Vegetace skal, lesostepi, lesu a lesnich lemu, ktera se na uzemi
nachazi, je druhove velmi bohata a zahrnuje radu chranenych a
ohrozenych druhu. Mezi nejvyznamnjsi zastupce vyssich rostlin patri
endemicky hvozdik moravsky (Dianthus moravicus). Z
dalsich to jsou napr. rerisnicnik skalni (Cardaminopsis
petraea), piskavice thesalska (Trigonella
monspeliaca), a kosatec nizky (Iris pumila)
nachazejici se hlavne na kopci Tabor. Z bezobratlych je na lokalite
hojne zastoupena kudlanka nabozna (Mantis religiosa), dale
se zde vyskytuje napr. pestrokridlec podrazcovy (Zerynthia
polyxena), tesarik obrovsky (Cerambyx cerdo), v
prirozenem useku reky Rokytne byl potvrzen vyskyt kriticky
ohrozeneho velevruba malirskeho (Unio pictorum). Dale na
zdejsích skalach muzete spatrit i celou radu plazu vcetne zakonem
chranenych - jesterku zelenou (Lacerta viridis), uzovku
hladkou (Coronella austriaca) a uzovku obojkovou
(Natrix natrix). Ptactvo je zastoupeno krepelkou
polni (Coturnix coturnix), sovou palenou (Tyto
alba), dudkem chocholatym (Upupa epops) a vyrem
velkym (Bubo bubo).
K ochrane tohoto unikatniho spolecenství byla zrizena Narodni
prirodni rezervace s naucnou stezkou. Dalsi informace

Nyni k samotne kesi. Souradnice vas nasmeruji na kopec Krizak
nad mestem Moravsky Krumlov. Je odsud pekny vyhled na udoli Rokytne
a slepencove skaly nad mestem. Toto misto navstivit musite, protoze
zde musite splnit ukol nutny k uznani logu.
K uznáni logu je nutne:
1. Poridit fotografii z navstivene oblasti, na ktere budete
zachyceni - napr. pohled do udoli, slepencove skaly, kvetouci
rostliny....
2. Na nas profil odpovedet na otazky:
- Co znamena v biologii slovni spojeni endemicky vyskyt?
- Slepencove skaly maji specificky barevny odstin. Jaky? A zkuste
urcit, ktery chemicky prvek je za to zodpovedny?
- Jaky letopocet je na krizi na kopci Krizak?

The countyside is formed by the river Rokytna which makes a lot
of meanders. So the topography is very rugged. At the area you can
find downhills of various orientation and inclination also vertical
rock walls. In combination with various land chemism form
conditions for differnt natural communities. The basement is formed
by pudding stones from Permian ages. According to the river they
are called Rokytna pudding stones. Somewhere you can find young -
Recent epoche sediments. The vegation of the rocks, forest steppe
and forrest hera is very rich. We can mention the most significant
plant - Dianthus moravicus - endemic range here. The others are
Cardaminopsis petraea, Trigonella monspeliaca and Iris pumila. At
the area we can find also a lot of Invertebrates -praying mantis
(Mantis religiosa), Great Capricorn Beetle (Cerambyx
cerdo) and endangered painter's mussel (Unio
pictorum). On the rocks there are a lot of reptiles such
as Green Lizard (Lacerta viridis), Coronella austriaca
and grass snake (Natrix Natrix). In the forest you
can see barn owl (Tyto alba), eurasian eagle owl (Bubo
bubo) and hoopoe (Upupa epops).
Now something to the cache. The coordinates leads you to the
hill called Krizak above the town Moravsky Krumlov.
For successful log you have to:
1.Take a photo of you at the visited area
2.To our profile answer the questions:
- What does it mean endemical occurrence in biology?
- The pudding-stone has specific color tone. Which one? It is due
to a high concentration of one chemical element. Which one?
- Which year is written on the cross on the hill Krizak
