Its small, rounded leaves have flattened stems, making them tremble and shimmer in the slightest breeze, creating a distinctive rustling sound. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Magnoliopsida - **Order:** Malpighiales - **Family:** Salicaceae - **Genus:** Populus ## Interesting facts - Aspen bark contains a natural pain reliever, similar to aspirin, used by ancient peoples! - Aspen's leaves turn a brilliant gold or yellow in autumn, lighting up entire mountainsides! - Its light, strong wood is used to make safety matches because it doesn't leave an afterglow! - The world's largest living organism is an Aspen clone named Pando, in Utah! ## Special abilities - **Trembling Leaves:** Aspen has unique flattened leaf stems that make its leaves tremble and shimmer, which helps maximize sun exposure and allows light to reach lower branches. - **Clonal Colonizer:** Aspen can form vast underground root systems, allowing it to sprout many new trees that are genetically identical, creating entire forests from one organism. - **Winter Photosynthesis:** Aspen has chlorophyll in its smooth, pale bark, which helps it continue to photosynthesize and produce energy even in winter when its leaves have fallen. ## Measurements & details - **Height:** 15-30 m - **Spread:** 5-10 m - **Edible:** No - **Size:** 20-50 cm - **Lifespan:** 60-150 years - **Fruit Type:** Capsule - **Growth Rate:** Fast - **Leaf Type:** Deciduous ## Ecological connections - **Eats:** [American Beaver](https://www.snappit.app/explore/american-beaver) (*Castor canadensis*) — Beavers fell aspens for food and building materials. - **Eats:** [Moose](https://www.snappit.app/explore/moose) (*Alces alces*) — Moose browse on aspen leaves, twigs, and bark, especially in winter. - **Eats:** [Elk](https://www.snappit.app/explore/elk) (*Cervus elaphus*) — Elk graze on young aspen shoots and strips bark during winter. - **Depends on:** [Yellow-bellied Sapsucker](https://www.snappit.app/explore/yellow-bellied-sapsucker) (*Sphyrapicus varius*) — Sapsuckers drill holes in aspen bark to drink sap and attract insects. ## Traits - [Deciduous](https://www.snappit.app/explore/traits/deciduous): Deciduous plants periodically shed all their leaves, typically during autumn or dry seasons. - [Broadleaf Tree](https://www.snappit.app/explore/traits/broadleaf-tree): Broadleaf trees are angiosperms characterized by flat, wide leaves that are typically shed annually in temperate climates. - [Fall Color](https://www.snappit.app/explore/traits/fall-color): Fall color refers to the seasonal change in foliage pigmentation, primarily in deciduous plants, displaying vibrant hues. - [Rapid Growing](https://www.snappit.app/explore/traits/rapid-growing): Rapid growing plants exhibit accelerated growth rates, quickly increasing in size and biomass within a short period. - [Mountain](https://www.snappit.app/explore/traits/mountain): This habitat trait identifies species found in mountainous regions, characterized by high elevation, steep slopes, and varying climate zones. ## Collections - [Trees](https://www.snappit.app/explore/collections/trees) ## Safety **Danger:** 1/5 · Very low Do not pick or eat anything you find. Some plants and mushrooms can be harmful. ## Frequently Asked Questions ### How to identify Aspen? Compare leaves or needles, how they attach to the twig, buds, bark and the shape of the crown.
