The vegetation in the Vancouver area was originally temperate rain forest, consisting of conifers with scattered pockets of maple and alder, and large areas of swampland (even in upland areas, due to poor drainage).[45] That they can grow in Vancouver is an indicator of the city's temperate climate in comparison to the rest of Canada. The conifers were a typical coastal British Columbia mix of Douglas-fir, Western red cedar and Western Hemlock.[46] The area is thought to have the largest trees of these species on the British Columbia Coast. Only in Seattle's Elliott Bay did the size of trees rival those of Burrard Inlet and English Bay. The largest trees in Vancouver's old-growth forest were in the Gastown area, where the first logging occurred, and on the southern slopes of False Creek and English Bay, especially around Jericho Beach. The forest in Stanley Park was logged between the 1860s and 1880s, and evidence of old-fashioned logging techniques such as springboard notches can still be seen there.[47]

Many plants and trees growing throughout Vancouver and the Lower Mainland were imported from other parts of the continent and from points across the Pacific. Various species of palm trees grow in the city in isolated cases, as do large numbers of other exotic trees such as the monkey puzzle tree, the Japanese Maple, and various flowering exotics, such as magnolias, azaleas, and rhododendrons. Some rhododendrons have grown to immense sizes,[citation needed] as have other species imported from harsher climates in Eastern Canada or Europe. The native Douglas Maple can also attain a tremendous size. Many of the city's streets are lined with flowering varieties of Japanese cherry trees donated from the 1930s onward by the government of Japan. These flower for several weeks in early spring each year. Other streets are lined with flowering chestnut, horse chestnut and other decorative shade trees.
