Rainfall Monitoring

Rainfall readings were taken in both the village of Accompong as well as traditional hunting grounds in the forest core over the 2019 field season. Indigenous team members  continue to take rainfall readings in the village

Data loggers

Data loggers have been placed in the village as well as the hunting grounds; they take hourly logs of temperature, humidity, and dew point. Aquatic data loggers have also been placed in three water sources to take hourly temperature readings.

Rainy season drought

Rainy season looks distinctly different in 2019/20 than it has in previous years. Days of heavy rainfall punctuate long periods of no rain. Rain was in fact more frequent during the end of the dry season, when much of the island still experienced significant drought, than during the heart of the rainy season. Local indigenous researchers misplaced the four readings (of less than 30) that occurred over the three-week period that appears blank ion the graph (between October and November). 

Accompong's microhabitat

It has been a long held assumption that rainfall in heaviest in the forest core than the periphery. However, the geographical feature specific to Accompong (the large verdant gorge around which the village was built) almost serves as hot, humid soup bowl from which updrafts can often be seen forming. As a result, the village often sees more rain than the core - particularly in this year's drought season. This makes the village, with its own microhabitat, a particularly important location for observing species presence.

Temperature/humidity

In the forest core, a distinct fall in temperature and  humidity can be seen in the period without rain (between the 13th August and 22nd August 2019). These extended dry spells can begin to have significant impacts on  both the microhabitats within the forest, and the ecosystems they support.
