And to hear forestry experts tell it, it's a dire threat to Ontario's oak trees. Oak wilt has been found in Belle Isle, Mich., about 500 metres from the Canadian border.

The oak tree will become part of the city's official symbols, which also include a flag, coat of arms and the mayor's chain of office. More information on oak trees in Toronto can be found here.

With a girth of 6.1 meters (20 feet), the tree ranked in the top 100 of London’s 600,000 oak trees for size, according to the Woodland Trust.

Players can now find fallen trees as a decorative variant of trees. These blocks come in the four following variants — oak, birch, jungle, and spruce.
