Wroshyr
native to the planet Kashyyyk, this species of trees could grow to heights measured in kilometers, with a few specimens tall enough to reach the clouds. Wookiee scientists located wroshyr trees with diameters that were several kilometers across, a fact that helped them support their massive trunks. Wroshyr trees dominated the planet's surface, extending to the tiny polar caps and the small desert located at the equator. While the surface of Kashyyyk was estimated to be forty-percent covered by water, the commingled wroshyr trees blocked any view of the water from space. The Wookiees who were native to Kashyyk built their cities in wroshyr trees, taking advantage of the tree's natural strengths to create their cities. The branches of a wroshyr tree merged with one another when they intersected, branching out to form vast networks of limbs. As these networks expanded, the Wookiees, could train them to grow in certain directions, allowing them to form living buttresses and walls. The merging of two wroshyr branches stood as a symbol of the unity and strength of the Wookiee people. The upper portion of a wroshyr tree was set aside for nursery rings, where young Wookiees were raised. Even at these heights, the wroshyr trees measured almost half a kilometer in diameter. Each wroshyr tree reproduced by producing cones every 100 years. Each cone contained a single seed, which was protected by the cone until it fell to the ground. Wookiees known as Tree Carers often gathered the fallen cones, storing the seeds for later planting.
