@backpackerbecky_: Welwitschia mirabilis - one of the longest-living plants in the world, living for over 1,000 years, with some even reaching up to 2,000 years or more! 🤯 Found in Namibia 🇳🇦 and Angola 🇦🇴  Welwitschia mirabilis plant 🌱 is considered a living fossil because its species has existed for over 100 million years, virtually unchanged since the time of the dinosaurs 🦕! So, while it may not be the oldest individual plant, it is one of the most ancient types of plants in terms of evolutionary history. It can survive 5+ years without rain sometimes even 10! But how can it survive without water 💦 in a desert? 🌵🏜️ 1. Fog Harvesting (Hydraulic Efficiency) One of the most remarkable ways Welwitschia survives is by capturing moisture from the thick fog 🌫️ that rolls in from the Atlantic Ocean 🌊. The plant has specialized leaf structures that can absorb moisture from the air, even when there’s no rain. The leaves 🍃 are covered with fine hairs (trichomes) that trap water droplets from the fog. This enables the plant to “drink” the moisture in the air and stay hydrated without direct rainfall. 2. Deep Root System The plant’s roots 🪾 grow deep into the ground, sometimes up to 30 meters (98 feet) deep, where it can access underground water reserves. These long, deep roots allow Welwitschia to tap into moisture that is inaccessible to many other plants. The roots also help the plant stay anchored in the desert, where the winds can be extreme. 3. Slow Growth Rate Welwitschia has a very slow growth rate, which helps it conserve energy and water. This slow growth also means the plant does not require large amounts of water to sustain itself over long periods of time. 4. Adapted Photosynthesis The plant uses CAM (Crassulacean Acid Metabolism) photosynthesis, which is a specialized process some desert plants use to minimize water loss. During the day, when the heat is intense, the plant keeps its stomata (pores) closed to prevent water from evaporating. At night, when temperatures are cooler and humidity is higher, the stomata open and the plant takes in carbon dioxide to perform photosynthesis. This process significantly reduces water loss compared to typical plants that photosynthesize during the day. 5. Long, Durable Leaves Welwitschia’s two long, strap-shaped leaves are tough and leathery, which helps reduce water loss through evaporation. They also continue to grow throughout the plant’s life, constantly replenishing themselves. 6. Survival through Drought The plant’s metabolism slows during long dry periods, essentially entering a kind of dormant state. This allows it to survive extreme droughts, sometimes for years without water, by reducing its need for moisture. In essence, Welwitschia survives in the desert by making the most of every bit of moisture it can find, whether that’s from fog, underground water, or rare rainfall. Its ability to adapt to such a harsh environment is a key reason why it’s one of the oldest and most unique plants on Earth! 🌍 Nature is amazing! #angola #travelangola #angolatravel #africatravel #travelafrica
