Basic information
Sample name: Cevennes National Park (S2)

Reference: J. Fonderflick, A. Besnard, A. Beuret, M. Dalmais, and B. Schatz. 2014. The impact of grazing management on Orthoptera abundance varies over the season in Mediterranean steppe-like grassland. Acta Oecologica 60:7-16 [ER 2151]
Country: France

Coordinate: 44° 17' N, 3° 31' E
Basis of coordinate: stated in text
Geography comments: "on a high limestone plateau (Causse Mejean)" and specifically on "an experimental farm... managed by the Cevennes National Park"
altitude 950 to 1100 m
Climate and habitat
Habitat: temperate savanna
Altered habitat: pasture
Protection: national/state park
Substrate: ground surface
WMT: 23.0
CMT: 3.0
MAP: 1000.0
Habitat comments: "steppe-like grasslands with some cultivated zones" with a "mixed continental and Mediterranean climate... This study was carried out in seven pasture areas, five of which had been grazed by sheep every year for at least 10 years, and two of which had not been grazed (ungrazed grassland) for at least six years and were used as control plots"
Life forms: orthopterans
Sites: 7
Sampling methods: line transect, hand capture, visual
Sample size: 1214
Years: 2010
Seasons: summer
Sampling comments: "We randomly placed 25 10-m2 plots in each of the seven pastures" and performed a sampling session "lasting 4-5 days" and specifically starting on 26 July; "we counted and identified Orthoptera (Ensifera and Califera) along a permanent 10-m2 line-transect (10 m in length 1 m in width, defined by two permanent wooden markers)"; most identifications were visual but "a local sample" was drawn to establish "a mean ratio of the two species" in each of three genera; the ratio apparently does not affect the actual reported counts
