HAVRANKA
Prirodni pamatka Havranka - je to vlastne
nejvetsi trojske vresoviste zvane Pusta vinice. Svah je tvoren
prevazne vresovým porostem a spolecenstvim teplomilnych rostlin.
Souvisle vresoviste je prechodovym clankem mezi nekdejsi
hospodarskou kulturou a hajem. To ze zde kdysi po zpustnutí pry
nejstarsi vinice vznikla pastvina, melo za nasledek posleze prave
vznik vresoviste ( neb kozy a ovce vsechno ostatni v zarodku
sezraly, ale vres jim nejede - aspon to mi kdysi, pri psani zivotne
prostredni seminarky, tvrdily botanicke kapacity 
Soucasna udrzba spociva prave v odstranovani
naletových drevin ( uz zase za pomoci koz a ovci ) a potlacuje prirozeny proces zarustani, ktery by
vedl k promene v neprilis vzacny haj.
Z mista se vam otevre pekny vyhled na Prahu a taky na mista ulozeni
zhruba tak 6ti blizkych kesek. 
A pokud prijedete na horskem kole, prosim vezmete to dolu cestou a
ne skrze vresoviste, jak to bohuzel mnoho bikeru dela.
dodatek pro kocarkare: od severu lze s timto geovozitkem
prijet: teren 1,5 hvezdicky, z jihu je to po schodech:teren 2,5
hvezdicky
ENG: Natural sanctuary Havranka - this is the biggest Troja's
heathland called Wasted Vineyard. Heathland is situated on the
hillside, where once upon a time :) was the oldest local vineyard.
After vineyard, place turned into grassland and finally ( with help
of sheep and goats, which ate everything except heather) turned
into heathland.
From the cache, you can see nice view over the city. And over about
6 other nearby caches. :)
for bikers: please ride the road, not trough the
heathland.
