Regina, Saskatchewan

==Geography==

The city is situated on a broad, flat, treeless plain.  There is an abundance of parks and greenspaces: all of its trees — some 300,000<ref name="Coneghan">Coneghan.</ref> — shrubs and other plants were hand-planted.<ref>[http://esask.uregina.ca/entry/regina.html "Regina," ''The Encyclopedia of Saskatchewan''] {{Webarchive|url=https://web.archive.org/web/20080429215846/http://esask.uregina.ca/entry/regina.html |date=29 April 2008 }}. Retrieved 11 July 2007.</ref> As in other prairie cities, [[American elm]]s were planted in front yards in residential neighbourhoods and on boulevards along major traffic arteries and are the dominant species in the urban forest.

In recent years the pattern of primary and high school grounds being acreages of prairie sports grounds has been re-thought and such grounds have been landscaped with artificial hills and parks. Newer residential subdivisions in the northwest and southeast have, instead of spring runoff storm sewers, decorative landscaped lagoons.

The streetscape is now endangered by [[Dutch elm disease]], which has spread through North America from the eastern seaboard and has now reached the Canadian prairies; for the time being it is controlled by pest management programs and species not susceptible to the disease are being planted; the disease has the potential to wipe out Regina's elm population.<ref>[http://www.cbc.ca/canada/saskatchewan/story/2007/07/17/trees-regina.html?ref=rss CBC "Saskatchewan Story" article on Regina's trees] {{webarchive |url=https://web.archive.org/web/20081226000330/http://www.cbc.ca/canada/saskatchewan/story/2007/07/17/trees-regina.html?ref=rss |date=26 December 2008 }}</ref><ref>[http://www.regina.ca/trees/ded.htm Dutch Elm Disease Control Program.] {{webarchive |url=https://web.archive.org/web/20071127193133/http://www.regina.ca/trees/ded.htm |date=27 November 2007 }}</ref>
