Seasonal rains turn Northern Borders plains into ‘green gold’ with Stipa capensis bloom

RAFHA: Seasonal rainfall has transformed parts of Saudi Arabia’s Northern Borders region into a sweeping natural tapestry, as the native grass Stipa capensis spreads across valleys and plains west of Rafha.

The plant now carpets lowlands south of Tal’at Al-Tumayyat, where golden and green hues ripple across the landscape, reflecting the renewal of vegetation cycles and the ecological balance of the open desert ecosystems, the Saudi Press Agency reported.

At sunset, the grasslands take on a particularly striking appearance, blending warm earth tones with the fading sky — a seasonal display that underscores the region’s resemblance to natural savanna environments.

Environmental specialists attribute this vegetation density to seasonal rainfall, highlighting the resilience and diversity of northern Saudi Arabia’s ecosystems, which closely resemble natural savanna environments.

Classified under the Poaceae family, Stipa capensis typically grows up to 50 cm tall and is distinguished by its fine, hair-covered leaves and delicate, needle-like awns. It thrives in sandy soils and open plains, particularly in the prairies surrounding Arar.

Often referred to as part of the “green gold” of the north, the plant plays a vital ecological role. It provides nutrient-rich forage for livestock such as camels and sheep, while also supporting local wildlife and contributing to soil stability.

Beyond grazing, Stipa capensis has practical uses in some communities, including traditional crafts, underscoring its broader environmental and economic value.

Officials and environmental observers note that such seasonal blooms are essential indicators of ecosystem health, reinforcing the importance of rainfall patterns in sustaining biodiversity across the Kingdom’s landscapes.
