Wenchi
Basic information
Sample name: Wenchi
Sample aka: Brong-Ahafo

Reference: E. M. Attua and O. Pabi. 2013. Tree species composition, richness and diversity in the northern forest-savanna ecotone of Ghana. Journal of Applied Biosciences 69:5437-5448 [ER 1109]
Geography
Country: Ghana

Coordinate: 7° 47' N, 2° 15' W
Basis of coordinate: estimated from map
Geography comments: "approximately central to the Brong-Ahafo region of Ghana, between latitudes 722' - 80'N and longitudes 132'- 225'W"
Fig. 1 shows that the study area is actually within about 738' - 756' N and 155' - 235' W, centered slightly to the west of Wenchi
altitude is for Wenchi and is from Lacombe et al. (2012, Hydrological Sciences Journal)
Climate and habitat
Habitat: tropical/subtropical savanna
Substrate: ground surface
MAT: 23.9
MAP: 1200.0
Habitat comments: "savanna woodland interspersed with high forest mosaics and gallery forests along banks of streams and rivers" and sites were distributed across "near-forest ecotone... near-savannah ecotone" and "mid-ecotone"
there is significant disturbance of forests in the area but it is not clear if the transects per se are disturbed
MAP 1000 to 1400 mm
Methods
Life forms: trees
Sites: 9
Site area: 10.290
Sampling methods: line transect
Sample size: 1450
Years: 2010, 2011
Minimum size: 10.0cm dbh
Sampling comments: "In each site, the plotless sampling technique was applied along three transects laid at least 1km apart"
tree density per ha was estimated using an equation that is base on "the mean distance between trees" along a transect; density figures for the three sites imply effective areas of 2.70, 4.09, and 3.5 ha
