Habitat surveys

The first field visit to the Cuajiniquil and Térraba-Sierpe sites took place in August 2018. This was an opportunity to inspect the reference sites and areas to be restored prior to installing field monitoring equipment.

A second visit to the sites was made at the end of November/early December 2018 to install Thalimedes sensors to determine the behaviour over the hydro-electric period and the soil topography. Soil samples were taken from the restoration area, especially in Térraba-Sierpe. A visit was also made to the Pitahaya region to identify a potential site for restoration.

The first phases of the restoration work include an assessment of the local environment:
• Selection of restoration areas and a reference area for data calibration

  • Analysis of the restoration and reference area’s environmental conditions
  • Monitoring of the physicochemical conditions of interstitial water
  • Analysis of the physicochemical parameters of the sediment
  • Analysis of forest structure and physiognomic types of the reference forests
  • Primary productivity (leaf-litter production and phenological behaviour)
  • Biomass and carbon in reference forests (quantification of carbon accumulated in the soil)
  • Methane concentration in the restoration region and a forest dominated by Rhizophora mangle.
