In Darjeeling, which is above , temperate forest trees like oaks, conifers, and rhododendrons predominate. Embryophytes include the vascular plants, such as ferns, conifers and flowering plants. Larches are among the few deciduous conifers, which are usually evergreen. Both conifers and deciduous trees can become conjoined. Outside the breeding season, mourning doves roost communally in dense deciduous trees or in conifers. They favour old forests with a mix of conifers and deciduous trees. In the latter conifers and rhododendrons flourish exceedingly. Rosin is obtained from pines and some other plants, mostly conifers. Vegetation is more luxuriant, consisting principally of southern beech and conifers. All extant conifers are perennial woody plants with secondary growth. It grows in dense clusters on stumps and logs of hardwoods and conifers. The montane rainforests of Tasmania are dominated by Tasmanian endemic conifers (mainly "Athrotaxis" spp.). Alders largely help create conditions favorable for giant conifers that replace them. Like in the Cretaceous, southern beeches, Podocarpaceous conifers, "Nothofagus", and Proteaceae angiosperms were proliferous. Juniper berries may be the only spice derived from conifers.
