Preheat oven to 300 F. Line two baking sheets with parchment paper.
Combine oats, coconut, flour, salt, cinnamon and brown sugar in a large bowl and mix well.
Combine butter, maple syrup and corn syrup in a medium saucepan. Heat over medium heat until butter melts, stirring occasionally. Remove from heat.
Combine baking soda and boiling water, stir to dissolve. Add to maple syrup mixture, and mix well. Add maple extract. Stir all of that into dry ingredients. Add pecans; mix well.
Place 2" balls of dough on baking sheets, 3 inches apart. Flatten slightly.
Bake 18 to 20 minutes, until golden brown and set. If you want to add pecan halves to the top as a garnish, add them now.
Cool on the baking sheets 5 minutes; transfer to a wire rack to cool completely.
