We plant a variety of food-bearing trees to support local nutrition and ecosystems.
Three of the species we commonly plant across Samburu County are the African Olive, Kei Apple, and Meru Oak. Read on to learn how these remarkable trees support both the diet and culture of the community!
1. African (Wild) Olive
The Fruit
The African Olive produces a deep, dark purple fruit. These olives are exceptionally rich in the antioxidant Vitamin E and heart-healthy mono-unsaturated fatty acids. They are also an excellent source of essential minerals, including calcium, magnesium, potassium, and iron. Because they store well and are so nutrient-dense, these olives serve as a vital subsistence food during droughts.
Cultural & Practical Uses
This resilient tree can live for centuries, growing slowly to produce a hard, durable wood known as lorien in Samburu. Lorien plays a deeply important role in traditional rites: it is burned in ceremonies and is considered a source of protection against evil. The bark of the tree is used for medicinal purposes and boiled into a tea to treat various ailments, including tapeworms.
2. Kei Apple
The Fruit
The kei apple produces plentiful, bright yellow fruit measuring 4–5 cm in diameter. Like the African olive, this fruit is incredibly nutrient-dense, boasting 83 milligrams of Vitamin C per 100 grams, nearly double that of an orange! It is rich in essential and non-essential amino acids (including glutamic acid, aspartic acid, and leucine), as well as potassium, phosphate, and sodium. The fruit can be enjoyed fresh or made into delicious jams.
Cultural & Practical Uses
An evergreen species native to dry woodlands, the kei apple is highly drought-resistant and remarkably hardy. Much like Moringa, it thrives in nutrient-poor soils where other fruit trees struggle. It has long, sharp thorns that naturally protect its leaves and fruit from grazing animals. Because of this built-in defense system, we frequently plant kei apple trees close together to form a "live fence" around homes and school agroforests.
3. Meru Oak
The Fruit
The Meru Oak bears a soft, black fruit that is commonly eaten during food shortages. It is a powerful protection against "hidden hunger" (nutrient deficiencies) because it contains high concentrations of Vitamins A and C.
Cultural & Practical Uses
This majestic tree is endemic to Kenya. Because its hard, durable wood is highly prized as timber for furniture and paneling, overharvesting has unfortunately landed the meru oak on the IUCN Red List of Threatened Species. With proper care, especially during the dry seasons, it grows beautifully. It has become highly valued by local communities for both conservation and nutrition.
