Physical soil and water conservation has been implemented to enhance infiltration, and vegetation growth. There are five guards to protect the exclosure. Field observations showed that however some illegal grazing occurred in the exclosure in 2018.

Benefits for the community
Setting aside such areas fits with the long-term vision of the communities were hiza’iti lands are set aside for use by the future generations. It has also direct benefits for the community:
 * improved ground water availability
 * honey production
 * climate ameliorator (temperature, moisture)
 * the sequestered carbon (in total 53 tonnes per ha, dominantly sequestered in the soil, and additionally in the woody vegetation) is certified using the Plan Vivo voluntary carbon standard, after which carbon credits are sold
 * the revenues are then reinvested in the villages, according to the priorities of the communities; it may be for an additional class in the village school, a water pond, or conservation in the exclosure.
