Habitat: Mediterranean woodland

Protection: national/state park

Substrate: ground surface

MAT: 13.6

MAP: 147.0

Habitat comments: "rainforest patches... on the summits of coastal mountains... within a matrix of semiarid scrub vegetation... mediterranean- arid with hot-dry summers and cool winters" with "around 95% of annual rainfall" falling "between June and August"
habitat is unaltered and therefore not designated as fragmentary

Life forms: trees

Sites: 3

Site area: 0.21

Sampling methods: line transect

Sample size: 120 individuals

Years: 2003

Net or trap nights: 0

Size min: 5.0

Basal area status: not stated

Sampling comments: "we set up three parallel transects... oriented approximately from north to south... separated from each other by at least... 25 m" with "ten sampling points separated by 20 m intervals along each transect line (200 m long)" with sampling "using the point-centered quarter method... At each point, we recorded the distance from the four nearest trees to the sampling point" (therefore, 3 x 10 x 4 = 120 trees were sampled; counts are back-computed from per 0.1 ha densities using this figure, and sampling area of ha is back computed from the sum of densities divided by 120)
basal area for all patches combined is illustrated but no figures are given
