Ulvikapollen

SEA MEADOW

When the lush beach area innermost in Ulvikapollen was protected, the bird life was instrumental to the decision. The plant diversity is just as impressive. In Hordaland sea meadows such as this are rare small in size - they are more common in coastal environments.

A sea meadow is a gently sloping beach with pasture vegetation on loose sediment deposits. Though they tend to be naturally small, these characteristic ecosystems have been made even smaller many places because of farming or other development. Those that are left in the fjord country are most often found in brackish water areas on a delta.

In Ulvikapollen the outer zone of vegetation gets flooded with tidewater. Here, several common beach plants grow, including brackish-mud rush, slender spike rush and sea milkwort. On this fine-grained bottom the rare species horned pondweed is abundant. Other rare plants include grey club rush and two species of sea grass. In the tidal zone there is lush swamp vegetation with, among others, iris, golden loosestrife and meadowsweet.

The birds are not especially interested in these rare plants, except for the ducks and swans who will happily graze on the sea grasses. Ulvikapollen is a good nesting place for wading birds such as the Lapwing, Red Shank and Snipe. A pair or two of Oystercatchers also nest in the sea meadow. Red-breasted Mergansers nest further out in the fjord, but come to Ulvikapollen with their youngsters. The area produces a lot of insects, which often attract swarms of swallows and swifts who harvest the water surface. The swifts are believed to come from afar - their nearest known nesting place is at Vossavangen.

It is in nesting time that Ulvikapollen is most popular with the birds. Many ducks find a good resting place here, and periodically a flock of Canada Goose stop off, and swim around in the fjords in Inner Hardanger. The shallow beaches are good fishing spots for the Grey Heron. The most numerous bird of all here is the Common Gull. Gulls from near and far gather in Ulvikapollen in the hope of finding a tasty dinner.

At the plant school south-east of Ulvik Centre a little house has been built with free access for the public. Here, you can find information about the preserve, while you stand close to some of the birds. If you are lucky, you might be able to spot a rare species. Ulvikapollen is one of the places in Inner Hardanger where rare species most often turn up.

Nøttekråka finst berre i fem hovudområde i Sør-Noreg. Eit av dei femner om nokre av dalføra i Indre Hardanger og Voss. Liene kring Ulvikafjorden er ein av dei sikraste stadene å sjå denne sjeldsynte fuglen.

 

Nøttekråka byggjer reir i tette granfelt, og på vårparten et ho ein god del frø frå bartrea. Men det er hasselnøtter som er hovudføda, og dei sankar ho i store mengder og lagrar på gøymestader på bakken. Mange fuglar har problem med å finna att slike deponi, men nøttekråka finn oftast fram, sjølv under tjukke snølag. Ho er lettast å få auga på om hausten, når fuglane flyg hektisk til og frå for å sikra vinterforrådet. Då må dei stundom dra 15–20 kilometer for å finna nok nøtter. Arten blir ikkje talrik i dei bratte liene i Hardanger – til det krevst for store revir.

 

Nøttekråka held seg stort sett på same staden, og det skal vera verkeleg smalhans før ho legg ut på vandring. Somme år, som i 1968 og 1995, vart likevel Vestlandet invadert av nøttekråker. Dette er sibirske fuglar, som elles lever av frø frå sembrafuru. Det er når frøsetjinga på denne furua har svikta, at nøttekråka fer så vide.
