# Beach Sheoak (*Casuarina equisetifolia*) The Beach Sheoak is a tall tree that grows near the beach. It has long, thin leaves that look like needles and can provide shade on sunny days. This tree is great for helping to keep the sand in place! - **Category:** [Plants](https://www.snappit.app/explore/categories/plant) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 6 - **Habitat:** Coastal areas ![Beach Sheoak](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Casuarina_equesitifolia_tree.jpg&width=800) Photo: Ethel Aardvark, CC BY 3.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Casuarina_equesitifolia_tree.jpg) ## Appearance The Beach Sheoak has drooping, wispy, green branchlets that look like pine needles but are actually its stems. Its bark is rough, grey-brown, and it produces small, woody, cone-like fruits that are actually hardened flower clusters. These features make it visually distinct from true pine trees. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Magnoliopsida - **Order:** Fagales - **Family:** Casuarinaceae - **Genus:** Casuarina ## Interesting facts - Indigenous Australians used its bark for medicine and its strong wood for tools. - Its 'leaves' are actually tiny green branchlets that can whistle in the wind! - The woody 'cones' are actually hardened female flower clusters, not true cones. - This tree is sometimes called 'Australian pine' because its wispy branches look like pine needles. ## Special abilities - **Salt Wizard:** Beach Sheoak can grow in salty soil and withstand sea spray, helping it thrive right by the ocean. - **Nutrient Builder:** Beach Sheoak has special root partners that turn air nitrogen into plant food, allowing it to grow in poor sandy soils. - **Sand Anchor:** Beach Sheoak has a strong, deep root system that helps hold sand in place, protecting beaches from erosion. - **Wind Dancer:** Beach Sheoak has flexible, drooping branchlets that bend with strong coastal winds, preventing damage. ## Measurements & details - **Height:** 600-3500 cm - **Spread:** 500-1000 cm - **Bloom Season:** Spring to Summer - **Edible:** No - **Toxicity:** None - **Lifecycle:** Perennial - **Pollination Method:** Wind ## Ecological connections - **Eats:** Casuarina Moth (*Metanastria hyrtaca*) — Larvae feed on its branchlets. - **Shelter:** Leaden Flycatcher (*Myiagra rubecula*) — Builds nests among its branches. - **Shelter:** [Osprey](https://www.snappit.app/explore/osprey) (*Pandion haliaetus*) — Builds nests in tall Casuarina trees. ## Traits - [Nitrogen Fixing](https://www.snappit.app/explore/traits/nitrogen-fixing): Describes organisms capable of converting atmospheric nitrogen into compounds usable by plants. - [Coniferous](https://www.snappit.app/explore/traits/coniferous): Coniferous plants are typically evergreen, bearing needles or scales and reproductive cones. - [Evergreen](https://www.snappit.app/explore/traits/evergreen): Evergreen plants retain their foliage throughout the year, never shedding all their leaves at once. - [Pollinator Magnet](https://www.snappit.app/explore/traits/pollinator-magnet): Describes plants that are particularly attractive and beneficial to a wide range of pollinating organisms. - [Coastal](https://www.snappit.app/explore/traits/coastal): Coastal habitats are dynamic environments located along the interface between land and sea, influenced by tides, waves, and saltwater. - [Keystone Species](https://www.snappit.app/explore/traits/keystone-species): Describes a species whose presence and role have a disproportionately large effect on its environment. ## Collections - [Plants](https://www.snappit.app/explore/collections/plants) ## Safety **Danger:** 1/5 · Very low Stay away from the tree's sharp needles and be careful when playing near the beach. ## Frequently Asked Questions ### How to identify Beach Sheoak?
