Initial conditions<br />

The Bohemian Karst landscape has been occupied by human<br />

settlements cont<strong>in</strong>uously for <strong>the</strong> last 7000 years (Stolz & Matoušek<br />

2006). Human settlements have always been connected to livestock<br />

graz<strong>in</strong>g, which has significantly shaped <strong>the</strong> landscape (Poschlod &<br />

WallisDeVries 2002). Due to <strong>the</strong> relatively low yield of dry grasslands<br />

on shallow soils over limestone, sheep and goat graz<strong>in</strong>g has been common<br />

<strong>in</strong> <strong>the</strong> Bohemian Karst, as <strong>the</strong>y tolerate lower-quality fodder and<br />

rocky terra<strong>in</strong>.<br />

Graz<strong>in</strong>g has ma<strong>in</strong>ta<strong>in</strong>ed open vegetation patches even <strong>in</strong> periods<br />

of closed canopy forest, and thus supported plant and animal species<br />

conf<strong>in</strong>ed to this type of habitat. From <strong>the</strong> conservation po<strong>in</strong>t of view,<br />

graz<strong>in</strong>g has played a positive role <strong>in</strong> <strong>the</strong> ma<strong>in</strong>tenance of species diversity.<br />

In <strong>the</strong> 20 th century, <strong>the</strong> extent of graz<strong>in</strong>g livestock decreased<br />

significantly <strong>in</strong> <strong>the</strong> Bohemian Karst, ma<strong>in</strong>ly after World War II, from<br />

roughly 10,000 to 100 goats and sheep (Novák & Tlapák 1974). Along<br />

with this, landscape changes occurred, whereby large open patches<br />

developed <strong>in</strong>to woodland, ei<strong>the</strong>r through succession (<strong>in</strong> remote and<br />

unprofitable places), or due to tree plant<strong>in</strong>g.<br />

The rema<strong>in</strong><strong>in</strong>g patches of grasslands are degrad<strong>in</strong>g due to <strong>in</strong>creas<strong>in</strong>g<br />

cover of dom<strong>in</strong>ant grasses and sedges at <strong>the</strong> expense of less<br />

competitive species, and plant and <strong>in</strong>vertebrate species diversity is decreas<strong>in</strong>g,<br />

small bare soil patches are disappear<strong>in</strong>g, litter is accumulat<strong>in</strong>g,<br />

and microhabitat diversity is decl<strong>in</strong><strong>in</strong>g.<br />
