Leaf water potential measurements with a Scholander-type pressure chamber at a mature tropical dry forest in northwestern Mexico.

This data set includes leaf water potential measurements from 8 tree species from a mature and well-preserved tropical dry forest in Alamos Sonora, Mexico. The field campaign was carried on September 15^th, 2023 at Racho el Guayabo within the reserve “Monte Mojino”, managed by Nature Culture International which lies within the federal protected area: “Area de Proteccion de Flora y Fauna Sierra de Alamos-Rio Chuchujaqui”, in the state of Sonora, Mexico. 

Data was collected at 5:00 am (pre-dawn), 8:00 am, 10:00 am and 12:00 pm (midday) in sun-exposed twigs of four different individual trees of six different genus.

Tree species measured:

*Plase note that when data was collected we believed we were sampling Acacia cochliacantha and now we understand that Vachellia is the revised genus revised for Acacia.

Ancillary data on shallow soil moisture (30cm) and meteorology are also provided.
