Country: Latvia


Coordinate: 56° 53' N, 21° 10' E
Coordinate basis: based on nearby landmark

Geography comments: south of Pavilosta (basis of coordinate)

Environment
Habitat: temperate coniferous forest

Protection: nature reserve

Substrate: ground surface

Habitat comments: "coastal dune habitats... The white dune bordering the sea was narrow and low, gradually transforming to the grey dune. This habitat covered about 20 m wide zone. The width of typical grey dune was about 50 m. Inlands the grey dune is bordered by dry grassland near Scotch pine plantings"

Methods
Life forms: orthopterans

Sampling methods: line transect,pitfall traps

Sample size: 920 individuals

Years: 2006

Days: 224

Seasons: spring,summer,autumn

Nets or traps: 40

Net or trap nights: 8960

Sampling comments: "One transect was selected for studies during the whole non-freeze period of the year – from April to November. 40 pitfall traps were arranged on 80 m long transect. Transect started on white dune then crossed typical grey dune and ended at dry coastal meadow. The distance between traps was 2 m. The traps were emptied and refilled every two weeks from 02.04.2006 to 12.11.2006" (i.e., over a 224 day span, meaning 17 collection events)
