We invite you to visit... In 1880 the site that was to become Glenwood City was a tranquil glen (valley) in the midst of huge forests. By 1885-1890 with the coming of the railroad and the lumber mills, Glenwood was the major trading center of the area with a population of 2000.
As mentioned above, other trees (such as birch trees) are tapped. 1  Coconut nectar (a.k.a., coconut syrup) - nectar collected from the coconut blossom sap. Tastes similar to toffee.  Coconut Sugar - coconut blossom sap boiled down till it crystalises.
As tree sap flows through the sapwood part of the tree, it produces carbon dioxide. This creates positive pressure and if there are any wounds or holes in the sapwood, the sap will ooze out. This is how harvesting saps from trees is achieved; cut or create a hole.
