15 Tree Seeds Preserved in Norway’s Famous Seed Vault

Deep inside a frozen mountain on the remote Norwegian island of Spitsbergen sits one of the world’s most important collections of seeds. Known as the Svalbard Global Seed Vault, this secure facility preserves backup samples from seed banks around the world.

The vault is best known for protecting food crops such as wheat, rice, corn, beans and potatoes. However, its collections also include seeds from trees and woody plants that provide food, medicine, animal feed, timber, shade and healthier soil.

In recent deposits, seeds from important African and Nordic tree species have been added to this remarkable collection. Here are 15 fascinating trees and woody plants represented in the international conservation work connected with the Svalbard Global Seed Vault.

What Is the Svalbard Global Seed Vault?

The Svalbard Global Seed Vault opened in 2008. It was built inside a sandstone mountain near Longyearbyen, Norway, far above the Arctic Circle.

Seed banks from different countries can send duplicate samples of their collections to Svalbard for safekeeping. The original seed bank continues to own its seeds and controls access to them. The vault simply provides a secure backup in case the original collection is damaged or lost.

Seeds are sealed inside special moisture-resistant packages, packed into boxes and stored at approximately 0°F, or –18°C. The cold and dry environment slows the aging process and allows many kinds of seeds to remain viable for decades.

1. African Baobab

Botanical name: Adansonia digitata

The African baobab is one of the most recognizable trees in the world. Its enormous trunk can store water, helping the tree survive extremely dry conditions.

Baobab fruit contains vitamin C and other valuable nutrients. The leaves, seeds, bark and fruit have all been used by local communities. Protecting baobab seeds helps preserve a tree that supports both people and wildlife throughout dry regions of Africa.

2. Apple-Ring Acacia

Botanical name: Faidherbia albida

Apple-ring acacia is an important African agroforestry tree. Unlike many trees, it commonly loses its leaves during the rainy growing season and produces new foliage during the dry season.

This unusual cycle allows crops planted beneath the tree to receive sunlight during their most active period. Fallen leaves add organic matter and nutrients to the soil. The tree also helps fix nitrogen, making it valuable for restoring poor farmland.

3. White Thorn

Botanical name: Acacia polyacantha

White thorn is a fast-growing African tree with pale bark, feathery leaves and sharp thorns. It can be used for shade, livestock fodder, fuelwood and traditional medicine.

The species can grow in seasonally wet areas and is useful for restoring disturbed land. Preserving different populations may help researchers identify trees with improved drought tolerance, disease resistance or other valuable traits.

4. Sudan Teak

Botanical name: Cordia africana

Sudan teak is a broad-canopied tree native to parts of Africa. It produces useful timber, shade and edible fruit. Farmers sometimes grow it near homes, fields and coffee plantations.

Its flowers support pollinators, while its fallen leaves contribute organic matter to the soil. Preserving its genetic diversity may support future reforestation and sustainable farming projects.

5. Egyptian Riverhemp

Botanical name: Sesbania sesban

Egyptian riverhemp is usually grown as a shrub or small tree. It grows rapidly and can improve soil by fixing nitrogen.

Farmers use it for animal feed, green manure, shade, wind protection and erosion control. Its ability to grow quickly makes it useful in areas where damaged soil needs to be restored.

6. Tamarind

Botanical name: Tamarindus indica

Tamarind is a long-lived tropical tree famous for its brown pods filled with tangy pulp. The pulp is used in drinks, sauces, candies and many traditional dishes.

The tree also supplies shade, timber and traditional medicinal materials. Conserving diverse tamarind varieties helps protect differences in fruit flavor, productivity and tolerance to local growing conditions.

7. Moringa

Botanical name: Moringa oleifera

Moringa is sometimes called the drumstick tree because of its long seedpods. Its leaves, flowers, young pods and seeds have many traditional uses.

The tree grows rapidly and tolerates heat and seasonal drought. Different varieties may contain traits that make them better suited to particular climates, soils or food-production systems.

8. African Locust Bean

Botanical name: Parkia biglobosa

The African locust bean is an important tree across West Africa. Its seeds are fermented to produce traditional seasonings, while its fruit pulp can also be eaten.

Mature trees provide shade and can remain in farm fields while crops grow beneath them. Protecting the species helps preserve local food traditions and the genetic diversity needed for future planting programs.

9. Shea Tree

Botanical name: Vitellaria paradoxa

The shea tree produces nuts used to make shea butter. This valuable natural fat is used in cooking, skin-care products, soap and cosmetics.

Shea trees grow slowly and may take many years to begin producing nuts. Conserving seeds and maintaining living populations are both important for protecting the future of this culturally and economically significant tree.

10. Indian Jujube

Botanical name: Ziziphus mauritiana

Indian jujube is a heat-tolerant tree that produces small, sweet fruit. It can grow in dry regions where many conventional fruit trees struggle.

The fruit may be eaten fresh, dried or processed. Some varieties produce much larger or sweeter fruit than others, making genetic preservation especially useful for future breeding work.

11. Desert Date

Botanical name: Balanites aegyptiaca

The desert date survives in hot, dry environments across Africa and parts of the Middle East. It produces fruit containing an oil-rich seed.

Different parts of the tree are used for food, livestock feed, fuel, tools and traditional medicine. Its ability to tolerate drought makes it particularly interesting as climates become hotter and rainfall becomes less predictable.

12. African Mesquite

Botanical name: Prosopis africana

African mesquite is a native tree found in savannas and dry woodlands. It produces dense, durable wood that has traditionally been used for furniture, tools, construction and fuel.

The tree can survive demanding conditions and contributes to the structure of dryland ecosystems. Conserving its diversity could support restoration projects in degraded landscapes.

13. Senegal Mahogany

Botanical name: Khaya senegalensis

Senegal mahogany is a large African tree valued for its attractive and durable wood. It is also planted along streets and in parks because it develops a broad, shady crown.

Overharvesting and habitat loss can place pressure on valuable timber species. Secure seed collections provide an additional layer of protection for their genetic diversity.

14. Silky Oak

Botanical name: Grevillea robusta

Silky oak is native to Australia but is now grown in many parts of the world. It is often planted for shade, wind protection, timber and farm improvement.

Its narrow crown can make it suitable for certain agroforestry systems because crops may still receive filtered light beneath the tree. Preserving different seed sources helps researchers study growth rate, climate tolerance and wood quality.

15. Norway Spruce

Botanical name: Picea abies

Norway spruce is a major forest tree across northern and central Europe. It is used for lumber, paper production, windbreaks and Christmas trees.

Seeds collected from different regions may carry adaptations to local temperatures, rainfall patterns and growing seasons. Protecting this diversity may help forest managers develop healthier forests as environmental conditions change.

Why Are Tree Seeds Worth Protecting?

Trees grow slowly compared with many agricultural crops. If a genetically distinct tree population disappears, replacing it can be extremely difficult.

Tree seed collections preserve traits that may become important in the future, including resistance to disease, tolerance to drought, adaptation to cold and the ability to grow in poor soil. These traits can support forestry, ecological restoration, sustainable agriculture and plant breeding.

Trees also provide much more than wood. They protect soil, store carbon, shelter wildlife, support pollinators and supply people with fruit, nuts, medicine, oils and animal feed.

Can Every Tree Seed Be Stored in the Vault?

Not every tree species produces seeds that can survive conventional cold storage.

Seeds that tolerate drying and freezing are known as orthodox seeds. These are generally the best candidates for long-term seed-bank storage. Many pine, spruce and acacia relatives produce seeds that can be stored successfully under the right conditions.

Other trees produce recalcitrant seeds that are damaged when dried or frozen. Many tropical fruit trees fall into this category. These plants may need to be conserved in living collections, botanical gardens, tissue-culture laboratories or cryogenic facilities instead.

A Frozen Backup for the Future

The Svalbard Global Seed Vault is not designed to replace forests, farms or ordinary seed banks. Instead, it acts as a backup for collections maintained around the world.

Its boxes contain far more than dormant seeds. They hold valuable genetic traits, cultural traditions and possibilities for future generations. From the massive African baobab to the cold-hardy Norway spruce, preserved tree seeds may someday help restore landscapes, strengthen food systems and protect plant diversity.

Every seed stored in the Arctic vault represents a small but meaningful promise: if a valuable collection is lost, humanity may still have another opportunity to grow it again.
