Opis

Približno tretjina svetovnega pridelka hrane zraste na rastlinah, ki so jih oprašile živali, velik delež cesar s svojim nacrtnim zbiranjem peloda prispevajo cebele. Zaradi tega je pomen cebel za preživetje cloveštva kriticen. Med je poleg tega eden redkih prehrambenih izdelkov, ki ga ljudje uživamo nepredelanega. Vrednost pridelka, za katerega oprašitev so poskrbele cebele, samo v ZDA ocenjujejo na 15 milijard dolarjev. Tamkajšnji pridelovalci sadja, detelje in drugega pogosto povecujejo pridelek tako, da najamejo cebelarje, ki pripeljejo panje domacih cebel v bližino nasadov.

Clovek ogroža cebele predvsem z neselektivnim škropljenjem poljšcin s pesticidi. Pesticidi lahko zastrupijo cebele neposredno ali s kontaminacijo vira hrane. Pri domacih cebelah, kjer se populacijska dinamika najpozorneje spremlja, je to že privedlo do opaznega povecanja smrtnosti. Verjetno so pesticidi eden izmed faktorjev, ki prispeva k sindromu propada cebeljih družin (angleško Colony Collapse Disorder oz. CCD), ki je v zadnjem casu deležen veliko pozornosti strokovne in širše javnosti. Ce upoštevamo, da so cebele neposredno odgovorne za velik del svetovnega pridelka hrane, lahko izginjanje domacih cebel ob hkratnem izginjanju drugih opraševalcev privede do globalnih težav s preskrbo s hrano. V splošnem naj bi se škropljenje izvajalo zvecer, ko cebele niso aktivne. Vse cebele poleg kemikalij ogroža tudi izguba habitatov in sajenje monokultur, kar še povecuje odvisnost pridelka od domacih cebel.

Ce vas zanima, zakaj cebela pici, kako se cebele pogovarjajo, kakšno je satovje in kaj vse potrebuje cebelar, lahko to izveste, ce obišcite cebelarsko ucno pot na Cerkniškem jezeru. Speljana je na otoku Goricica sredi skrivnostnega in spreminjajocega se Cerkniškega jezera. Opremljena s poucnimi tablami nudi osnovna znanja o cebelji družini, življenju cebel, hrani cebel, cebeljih pridelkih, boleznih cebel, zgodovini cebelarstva, medovitih rastlinah, vrstah medu in njegovih zdravilnih ucinkih. Pot se zacne v Pretržju, med Dolenjim Jezerom in Otokom, pri cebelnjaku Cebelarskega društva Cerknica. Pot je dolga le 250 m, za ogled potrebujete 1,5 ure. V cebelnjaku na ucni poti se lahko oskrbite tudi z domacim medom in izdelki iz medu. Ucno pot si lahko ogledate sami ali pa se dogovorite za voden ogled pri Cebelarskem društvu Cerknica.

Dostop

Dostop do cebelarske ucne poti je iz Cerknice skozi Dolenje jezero proti vasi Otok. Parkiranje je možno neposredno ob ucni poti (tocka PARK), lahko pa parkirate tudi prej in se do tja odpravite peš po nasipu. Seveda je dostop mogoc tudi s kolesom.

Dostop do zaklada je mogoc skozi celo leto, z možno izjemo dni, ko je jezero tako polno, da preplavi cesto. To se zadnje case dogaja le vsakih nekaj let.

Zaklad

Zaklad je 1,1 l Lock & Lock škatla. V njej je poleg knjižice vpisov, svincnika, šilcka in GC sporocila, ki naj ostanejo v zakladu, še nekaj manjših predmetov za menjavo. Prvega najditelja caka FTF priponka, ki jo lahko odnese s seboj za nagrado.

Description

Bees play an important role in pollinating flowering plants, and are the major type of pollinator in ecosystems that contain flowering plants. Bees either focus on gathering nectar or on gathering pollen depending on demand, especially in social species. Bees gathering nectar may accomplish pollination, but bees that are deliberately gathering pollen are more efficient pollinators. It is estimated that one third of the human food supply depends on insect pollination, most of which is accomplished by bees, especially the domesticated European honey bee. Contract pollination has overtaken the role of honey production for beekeepers in many countries. Monoculture and the massive decline of many bee species (both wild and domesticated) have increasingly caused honey bee keepers to become migratory so that bees can be concentrated in seasonally varying high-demand areas of pollination.

From 1972 to 2006, there was a dramatic reduction in the number of feral honey bees in the US, which are now almost absent. At the same time there was a significant though somewhat gradual decline in the number of colonies maintained by beekeepers. This decline includes the cumulative losses from all factors, such as urbanization, pesticide use, tracheal and Varroa mites, and commercial beekeepers' retiring and going out of business. However, in late 2006 and early 2007 the rate of attrition reached new proportions, and the term colony collapse disorder was coined to describe the sudden disappearances. After several years of research and concern, a team of scientists headed by Jerry Bromenshenk published a paper in October 2010 saying that a new DNA-based virus, invertebrate iridescent virus or IIV6, and the fungus Nosema ceranae were found in every killed colony the group studied. In their study they found that neither agent alone seemed deadly, but a combination of the virus and Nosema ceraneae was always 100% fatal. Bromenshenk said it is not yet clear whether one condition weakens the bees enough to be finished off by the second, or whether they somehow compound the other’s destructive power. "They're co-factors, that’s all we can say at the moment. They’re both present in all these collapsed colonies." Investigations into the phenomenon had occurred amidst great concern over the nature and extent of the losses. In 2009 some reports from the US suggested that 1/3 of the honey bee colonies did not survive the winter, though normal winter losses are known to be around 25%.

Apart from colony collapse disorder, many of the losses outside the US have also been attributed to other causes. Pesticides used to treat seeds, such as Clothianidin and Imidacloprid, have been considered prime suspects. Other species of bees such as mason bees are increasingly cultured and used to meet the agricultural pollination need.

Native pollinators include bumblebees and solitary bees, which often survive in refuges in wild areas away from agricultural spraying, but may still be poisoned in massive spray programs for mosquitoes, gypsy moths, or other insect pests. Although pesticide use remains a concern, the major problem for wild pollinator populations is the loss of the flower-rich habitat on which they depend for food. Throughout the northern hemisphere, the last 70 or so years have seen an intensification of agricultural systems, which has decreased the abundance and diversity of wild flowers.

If you want to know why a bee stings, how the bees talk, what is the honeycomb and what a beekeeper needs, you can find it out if you visit the Beekeeping learning trail at Lake Cerknica. The trail runs on Goricica island in the middle of mysterious and ever-changing Cerknica Lake. It is equipped with educational boards (only in Slovene language, unfortunately) that provide basic information about the bee family, life of bees, bee food, bee products, bee diseases, beekeeping history, honey plants, types of honey and its health benefits. The trail begins in Pretržje, between the villages of Dolenje jezero and Otok, at Beekeepers Association of Cerknica apiary. The path is only 250 m long but can take up to 1.5 hours. You can see the learning trail by yourself or can arrange a guided tour with the Beekeepers Association of Cerknica.

Access

One can access the learning trail by road from Cerknica through Dolenje jezero towards Otok. Parking is available nearby (waypoint PARK), or you can park earlier and walk to the site.

Cache is accessible throughout the year, with the possible exception of a few days when the lake is so full that it overflows the road. This happens usually only every few years.

Cache

Cache is a 1.1 liter Lock & Lock box. In addition to logbook, pencil, sharpener and GC note which are to remain in the cache, there are a few small items for trade. FTF badge is awaiting the first finder to be taken away as a small prize.

It is not very likely to come across muggles, but caution is still advisable. Hide the cache well afterwards to avoid some muggle finding it.
