Gede ruins regeneration project aims at assessing biodiversity on a 5 acre piece of land formerly a cropland, which has been replanted with indigenous tree species, which sits on a 70 acre piece of land within the Gede Ruins National Monument.
This project has brought in immense expertise from various research bodies, organizations and parastatals including National museums of Kenya (that stewards Gede Ruins National Monument), Kenya Forestry Research Institute(KEFRI), Malindi Museum Society, Michigan State University, University of Washington, and A Rocha Kenya.

The habitat was replanted 22 years ago, and the project involves measuring tree growth and soil content (an important indicator of carbon sequestration potential aimed at offsetting global climate change), bird and arthropod diversity. The project aims at comparing re-growth and biodiversity among different plots in the restored habitat.This will help evaluate relative effective tropical dry forest restoration on biodiversity conservation and ecosystem services along the East African Coast.
This project is, as far as we know, the only restoration project in East Africa focusing on indigenous tree species – an important endeavor, as it addresses important issues stemming from the introduction of a host of non-native species (Eucalyptus trees from Australia, and Neem from India) that are affecting water tables and myriad ecological interactions.
2012 and 2013 saw the implementation of phases one, two and three; that involved re-identification and re-labeling of the planted trees, growth measurement of all planted trees, and identification and measurement of all recruits.

Soil sampling falls under phase four , which was successful conducted on October 2014. We had to seek for an Archeologist opinion and supervision as we made pits and drilled agaers beneath the ground, and indeed, we brought to the surface a number of archeological artifacts ( local bodies and imported Chinese porcelain rings).

A total of four pits ( one meter cubed each) were made and soil collected in different horizons using the standard core samplers. Three of the pits were dug in the restored habitat and one in the primary forest. Both litter and ager soil samples were as well taken.

This will ultimately be used to assess bulky density, and carbon and nitrogen content. The KEFRI team (Gede station) is now in the process of analyzing the collected data and we hope to have the findings soon.What next? An Arthropod study, to assess diversity and distribution maybe?
