Population trends of birds in alpine habitats at Ammarnäs in southern Swedish Lapland 1972-2011
(2013) In Ornis Svecica 23(2). p.81-107- Abstract
- All birds were counted along six permanent routes (total
length 90 km) located in the low alpine zone (800–1000
m.a.s.l.) at Ammarnäs, southern Lapland, during fortyyears,
1972–2011. Eighty-three species were recorded;
average 41 species and 1677 birds per year. Number of
species as well as population size increased for waterfowl,
waders and other non-passerines but not for passerines.
Thirteen of the thirty-eight most regular species had
significant population trends, twelve of them positive.
The route counts correlated well with the number of pairs
in two adjacent territory mapping plots. The trends also
correlated positively with those... (More) - All birds were counted along six permanent routes (total

Thirteen of the thirty-eight most regular species had
significant population trends, twelve of them positive.
The route counts correlated well with the number of pairs
in two adjacent territory mapping plots. The trends also
correlated positively with those found in all mountain
routes of the Swedish Bird Survey. Although not quite
significant this similarity indicates that common largescale
factors are involved in governing the local population
changes. Several of the species that have their main
distribution at lower levels are expanding their ranges
into the alpine zone. Despite the predominance of positive
trends some species have more or less severe problems,
requiring deeper studies or conservation measures:
Melanitta fusca, Aythya marila, Philomachus pugnax,
Eremophila alpestris and Plectrophenax nivalis. (Less)
