| − | == Uses ==
| |
| − | Bigleaf maple has been used for creating syrup but it is not common. This is because [[sugar maple]] has a higher sugar content. Nevertheless, syrup production has become a localized industry in bigleaf maple groves where weather conditions (including sub-freezing winters) are especially suitable, such as near sea-level in British Columbia and at higher elevations along the West Coast from Washington through Northern California.{{Citation needed|date=February 2016}}

| − | Bigleaf maple is the only commercially important maple of the [[Pacific Coast]] region.<ref name="US Forest Service" />
| |

| − | The [[wood]] is used for applications as diverse as furniture, piano frames and salad bowls. Highly figured wood is not uncommon and is used for veneer, stringed instruments, guitar bodies, and gun stocks.
| |
| − | | |
| − | The wood is primarily used in [[Wood veneer|veneer]] production for furniture, but is also used in musical instrument production, interior paneling, and other hardwood products; the [[heartwood]] is light, reddish-brown, fine-grained, moderately heavy, and moderately hard and strong.<ref>{{cite book |last1=Arno |first1=Stephen F. |last2=Hammerly |first2=Ramona P. |date=1977 |title=Northwest trees |place=Seattle, WA |publisher=The Mountaineers}}</ref> [[Lakwungen]] First Nations people of Vancouver Island call it the paddle tree and used it to make paddles and spindle wheels.{{citation needed|date=October 2008}}

| − | In California, land managers do not highly value bigleaf maple, and it is often intentionally knocked over and left un-harvested during harvest of [[Douglas fir]] and [[redwood]] stands.<ref>{{cite journal |last=Bolsinger |first=Charles L. |date=1988 |title=The hardwoods of California's timberlands, woodlands, and savannas |journal=Resource Bulletin PNW-RB-148 |place=Portland, OR |publisher=United States Department of Agriculture, Forest Service, Pacific Northwest Research Station}}</ref>

Interest in commercially producing syrup from bigleaf maple sap has been limited.<ref>{{cite web |website=Island Net |url=http://www.island.net/~backlund/syrup_info.pdf |title=Maple syrup |archive-url=https://web.archive.org/web/20060925031921/http://www.island.net/~backlund/syrup_info.pdf |archive-date=September 25, 2006 }}</ref>

| − | Although not traditionally used for syrup production, it takes about 40 volumes of sap to produce 1 volume of maple syrup.

| − | == Big Tree ==
| |
| − | The current [[National register of big trees|national champion]] bigleaf maple is located in [[Lane County, Oregon]].
