The basin Bonis (39 ° 25'15 '' N and 16 ° 12'38 '') is located in the Sila Cosenza and is a sub-basin of the river Cino. It has an area of 139 hectares.
The basin , public property , was identified and designed from 1984 and equipped in 1986 with the aim of establishing a permanent laboratory for the study of the water balance at the basin level and water processes at the scale of slopes ( sub-basins ) , in forest stands ( Corsican pine ) , also in relation to the evolutionary dynamics leading to thinning operations . The monitoring of the outflows was carried out with the realization, in the closing section , of a building of measurement consists of a stilling reinforced concrete . The stretch of river bed upstream of the tank is channeled to a length of 32 meters and in the end parts extends in the shape of a funnel to link up with a bridle in cement concrete on the one hand and with the tank on the other side . From the point of view of forest cover the surface is affected by the 80% of populations of Corsican pine (Pinus laricio Poiret ) , largely man-made , made in the period between 1955 and 1970. The nuclei of natural origin , age next to that of reforestation , occupy the highest part of the pelvis in the left and right bank .
Within the basin , in May 2003 , in the village Cozzarella - Don Bruno , a tower was installed to measure the mass exchange (CO2 , H2O) and energy (sensible heat , H) between forest and atmosphere that makes use the eddy covariance technique . The tower is the site of forest further south in Italy and has the objective to study the dynamics of carbon exchange and evapotranspiration of a reforestation of Corsican pine . The decision to install the measuring station for the exchange of CO2 and water vapor in this basin was made to adopt an integrated measure of the hydrosphere - biosphere - atmosphere interactions . The station was installed in an artificial pine forest about 35 years old, planted on former pasture and sparse in 1986 , which represents the main ecosystem of the basin , and a principal of the Calabria region .. The morphology is slightly wavy . The geological substrate is composed of granitic rocks , the soils belong to the association Ultic Haploxeralfs , characterized by a clayey horizon with illuvial clay focused, often , even in the strip ( Dimase & Iovino 1996 Castrignanò & Buttafuoco 2004). From the point of view phytoclimatic the area is due to the hot sub Fagetum ( Pavari 1916) On the phytosociological , the pine forest is attributable to the association Hypochoerido - Pinetum laricionis , which can implant in areas uncovered by forming consortia which is generally quite sparse .
The pine forest has 637 trees per hectare, basal area of 45.4 m2 ha-1 , mean diameter of 29 cm and average height of 21.5 m , the leaf area index , measured with the LAI -2000 ( LiCor , Lincoln , Nebraska - USA ) was of 6.6 ± 0:18 m2 m -2. At this site are active , since June 2003, micrometeorological measurements and instrumentation to measure the exchange of carbon and water vapor.
