Ljubljansko barje - Rakova jelša
Ljubljansko barje meri 163 km2, oziroma 0,9 % slovenskega ozemlja. Ob vsakoletnih poplavah, je poplavljena površina območja do 80 km2.
Z geološkega stališča je to več kot 200 m globoka poznopliocenska udornina izpred dveh milijonov let, nastala na stičišču alpskega in dinarskega sveta.
Živalstvo
Veliki škurh (Numenius arquata) si gnezdo splete na tleh, na močvirnem travniku. Ko samica vali jajca, nepremično sedi na gnezdu v visoki travi in se zanaša na svojo varovalno barvo. Takrat je zanjo usodno, če jo najde pes, ki spuščen z vrvice prosto teka po Barju.
Kosec je vrsta travniške ptice in je edina v svetovnem merilu ogrožena vrsta, ki gnezdi na Ljubljanskem barju. Še pred desetimi leti je na barju gnezdila še ena globalno ogrožena vrsta ptice, južna postovka, ki pa je danes tam ni več.
Čeprav Ljubljansko barje obsega le odstotek celotne površine Slovenije ima zaradi izjemnosti habitatov na njem svoj dom tudi do 20 odstotkov populacije nekaterih vrst travniških ptic. Med njimi predvsem veliki škurh, katerega deset parov na Barju predstavlja edino stalno slovensko gnezditveno populacijo, s pomembnim deležem pa so zastopane tudi druge vrste: prepelica, priba, poljski škrjanec, repaljščica, močvirska trstnica, postovka. Na Ljubljanskem barju najdemo še nekatere ogrožene vrste gozdnih ptic in močvirskih ptic, vsega skupaj kar 107 vrst rednih in občasnih gnezdilcev, obenem pa je to območje, pomembno za prezimovanje in selitvene prelete številnih drugih vrst ptic.
Na Ljubljanskem barju najdemo ogroženo vlagoljubno populacijo barjanskega okarčka. Slednja ne živi nikjer drugje. Ponovno jo naseljujejo v Iškem morostu.
Na širšem območju Ljubljanskega barja živi okoli 45 vrst sesalcev, med najbolj ogroženimi pa je vidra, ki jo je mogoče občasno zaslediti ob Ljubljanici in Iščici. Pomemben člen barjanskega ekosistema so številne voluharice, ki živijo izključno na travnikih. Zelo redka je postala močvirskemu svetu prilagojena želva močvirska sklednica. Dvoživk (zelena rega, urh, rjava in zelena žabe) in nevretenčarjev je na barju še v izobilju, kar je tudi eden izmed razlogov za pestrost in številčnost ptic.
Rakova Jelša
Ime Rakova jelša izhaja iz dejstva, da je na omenjenem območju prisotnost jelše v takih količinah, da zastruplja zemljo in zato ostalim rastlinskim in živalskim vrstam povzroča bolezen raka. Zato je življenje na takem območju za navadne ljudi oteženo. V sedemdesetih se je območje najprej imenovala Rakasta jelša, vendar pa se je tekom let v ljudskih krogih tamkajšnega prebivalstva ime preoblikovalo v Rakova jelša.
Rakova jelša je edina soseska v Ljubljani z večinskim neslovenskim prebivalstvom. Nastala je s priseljevanjem prebivalstva iz območja nekdanje Jugoslavije od sedemdesetih let dalje. Proces priseljevanja prebivalstva iz nekdanje Jugoslavije v Slovenijo in Ljubljano ter nastajanje etničnih četrti kot je Rakova jelša je zanimivo iz socioekonomskega vidika značilnosti prebivalstva. Anketiranje lokalnega prebivalstva razkriva tudi zadovoljstvo s kvaliteto bivalnega okolja a hkrati nakazuje problematiko integracije priseljencev v novo okolje.

Ljubljana Marshes
The Ljubljana Marshes measure 163 km2 or 0.9% of Slovenia's territory. With annual floods, the flooded area of the area is up to 80 km2.
From a geological point of view, it is a more than 200 m deep Late Pliocene depression from two million years ago, formed at the junction of the Alpine and Dinaric worlds.
Fauna
The Great Woodpecker (Numenius arquata) weaves its nest on the ground, in a swampy meadow. When the female hatches eggs, she sits motionless on the nest in the tall grass, relying on her protective color. At that time, it is fatal for her if she is found by a dog that is running freely on the Marsh.
The blackbird is a species of meadow bird and is the only globally endangered species that nests in the Ljubljana Marshes. Ten years ago, another globally endangered bird species, the southern post-warbler, nested on the marsh, but it is no longer there today.
Although the Ljubljana Marshes comprise only one percent of the total area of Slovenia, up to 20 percent of the population of some species of meadow birds is home to it due to the exceptionality of its habitats. Among them, the great shearwater, whose ten pairs on the Marshes represent the only permanent Slovenian nesting population, while other species are also represented with a significant share: quail, priba, field lark, reed warbler, marsh reed warbler, postovka. The Ljubljana Marshes also contain some endangered species of forest birds and marsh birds, a total of 107 species of regular and occasional nesting birds, and at the same time this area is important for wintering and migratory flights of many other bird species.
On the Ljubljana Marshes, we can find an endangered moisture-loving population of the marsh okarček. The latter lives nowhere else. It is being repopulated in Iž morost.
About 45 species of mammals live in the wider area of the Ljubljana Marshes, and among the most endangered is the otter, which can occasionally be found along the Ljubljanica and Iščica rivers. An important member of the marsh ecosystem are numerous voles that live exclusively in meadows. A swamp bowl turtle adapted to the swamp world has become very rare. Amphibians (green rega, urh, brown and green frogs) and invertebrates are still abundant on the marsh, which is also one of the reasons for the diversity and abundance of birds.
Rakova Jelša
The name Crab alder comes from the fact that in the mentioned area there is a presence of alder in such quantities that it poisons the soil and therefore causes cancer to other plant and animal species. Therefore, life in such an area is difficult for ordinary people. In the seventies, the area was first called Rakasta alder, but over the years the name was transformed into Rakova alder in the folk circles of the local population. Rakova alder is the only neighbourhood in Ljubljana with a majority non-Slovenian population. It was created by the immigration of the population from the area of the former Yugoslavia from the seventies onwards. The process of immigration of the population from the former Yugoslavia to Slovenia and Ljubljana and the emergence of ethnic quarters such as Rakova alder is interesting from the socio-economic point of view of the characteristics of the population. The survey of the local population also reveals satisfaction with the quality of the living environment, but at the same time indicates the problem of integrating immigrants into the new environment.
AVANTURA
Avantura se začne pred mostom čez potok Curnovec. Tam parkirajte vozilo in prečkajte most ter se napotite južno, direktno proti Krimu. Na prvem križišču zavijte desno in sledite cesto do vmesne točke (tripod, na cca. 1.5 m višine). Na njej poiščite vsebnik z navodili, kako do zaključne lokacije z lettterbox-om. Leterbox se nahaja cca 75 m stran.
V leterbox-u je PVC zabojnik s klik pokrovom, dnevnik – log book, pisalo in štampiljka z zelenim odtisom ljubljanskega zmajčka, zaščitnim simbolom Ljubljane. V zabojniku je tudi dovolj prostora za odložiti kakšen manjši sledljivček.
Po zaklad se odpravite pripravljeni, primerno obuti in oblečeni. Posebej poleti ko je vegetacija bujna, se je treba zaščititi od kopriv in robidovja ter nadležnih komarjev, ki jih je v teh koncih kar vsepovsod mrgoli.
Lepo prosim, da po najdbi vse lepo zložite in vrnete na mesto, kako ste tudi našli.

The adventure begins in front of the bridge over the Curnovec stream. Park your vehicle there and cross the bridge and head south, directly towards Crimea. At the first intersection, turn right and follow the road to the intermediate point (tripod, app. 1.5 m high). On it, find a container with instructions on how to get to the final location with the lettterbox. Leterbox is located approx. 75 meters away.
In the leterbox there is a PVC container with a click lid, a log book, a pen and a stamp with the green print of the Ljubljana dragon, the trademark of Ljubljana. There is also enough space in the container to store a small tracker.
Go for the treasure prepared, appropriately shod and dressed. Especially in summer, when the vegetation is lush, it is necessary to protect yourself from nettles and blackberries and annoying mosquitoes, which are everywhere in these parts.
I kindly ask you to fold everything neatly after finding it and return it to the place you found it.
