See Where We Work

The Green Belt Movement set up a Geographical Information Systems (GIS) lab to help us cope with the increasing demand for reliable data from the field. The data helps us in decision making for our watershed based approach- ensuring more effective conservation and community development across Kenya. GBM works with communities to map their tree nurseries and tree planting sites.

Community Tree Nursery Groups

This interactive map shows the location of these community tree nurseries. If you click on the tree icon you will see the name of the community tree nursery group that takes care of the tree nursery and the number of participating households in that nursery group.

This location-specific information uses GPS coordinates; the same technology used in mobile devices for directions in cars and phones. It has been invaluable in the process of scaling up GBM’s work at the grassroots level. GBM uses this information to monitor and enable availability and distribution of indigenous seedlings required to meet the re-afforestation gaps in critical watersheds.

Tree Survival

We recommend monitoring the progress and growth of the young seedlings on the ground for a period of two to three years based on the tree species, size of the seedling during planting and the site characteristics. GBM field staff and the communities use GPSes to map the location of their planting sites (shown as a green tree icon) and the number of trees planted on the site for periodic monitoring.

GBM’s Monitoring team uses the vital information on the number of trees planted in each site, and the date of planting and condition of the trees, to ensure a high rate of tree survival and the sustainability of the project.
