Savary Island

Savary Island is an island in British Columbia, Canada. Located in the northern part of the Strait of Georgia, it is 144 kilometres (89 mi) northwest of Vancouver. It is approximately 0.8-1.5 km wide and 7.5 kilometres (4.7 mi) long. It has a permanent population of 100. In summer the population sometimes exceeds 2,000.

This island is composed mostly of unconsolidated material such as glacial till, marine clay, and sand. This comes primarily from the era as material deposited by meltwater streams from glaciers which advanced southward through the Strait of Georgia over 20,000 years ago. The Ice Age materials are overlain by Holocene (Recent) era deposits; their features include sand dunes. Bedrock is exposed only at the eastern end around Mace Point. Most of Savary's soils are sandy, with brown podzolic and podzol profile development.

Since deglaciation (approximately 10,000 years ago), continued erosion under the general influence of prevailing south easterly storm waves, has caused the disappearance of much of the "original island". What remains today is very much in flux as the twin forces of erosion and accretion gradually move or shift the boundaries of the island. As one study described it, "With no exterior sources of sediment, the Island will continue to cannibalize its south coast."

In the rainshadow of Vancouver Island, Savary receives between 950 and 1,300 mm of precipitation annually, with maximum amounts in late fall through mid-winter. No permanent streams exist on the island, but at least one spring may be found mid-island called Indian Springs. The dry warm summers and erodible soils condition distinctive ecologic settings and surface processes (including wind erosion and deposition). In addition, storm waves, which are predominantly from the southeast, have important erosion and sediment transport effects along the south shore of Savary. It is this unique combination of "ecologic settings", "surface processes" and "transport effects" which gives rise to the wonderful beaches of Savary.

Common trees are Douglas-fir, western hemlock, western red cedar, lodgepole pine, grand fir, red alder, bigleaf maple and arbutus. It is claimed that one of the largest arbutus trees in the world is on the island. A few western white pine are present. A tiny population of Garry oak occurs at the eastern end — the northernmost natural occurrence of this species along the coast. It has splendid beaches, arbutus groves, meadows, and sand cliffs. Salal is the most plentiful shrub in the forest understorey. Red huckleberry, evergreen huckleberry and red flowering currant are among the other shrubs present. Many of the open areas have been conquered by alien species such as Scotch broom, gorse and Himalayan blackberry.
