Mesquite: A Tree of Many Fruits

Trees have dotted the Texas landscape for years, and their various uses could be pondered for days. But what if you took that tree and made it into something better, more multi-purposed? Grafting trees has been around at least as far back as 5000 B.C. when the Chinese experimented with grafting fruit and nut trees for commercial purposes, and even Greek philosophers pondered the best way to graft plants. How about growing an assortment of disparate fruit from one tree? That’s what an artist in New York has done. Sam Van Aken grafted stone fruit, of antique and heirloom varieties, to one tree base. This inimitable tree has grafted branches from 40 different kinds of stone fruit and has been dubbed the “Tree of 40 fruit”.

As amazing and tasty as this sounds it really is not that new of a concept. What Mr. Aken has done is preserved fruit varieties by turning a simple tree into a versatile tree. Wildlife biologists are doing the same thing, but with mesquite. Mesquite is tree that can be the bane of a landowner, or a blessing, depending on how it is used. A mesquite tree left alone can reproduce on such a level that land has to be cleared every decade just to maintain them, much less eradicate them. However, if a mesquite tree is half-cut, this once pesky tree now provides the perfect loafing cover for quail. While mesquites left alone can provide some cover, once they grow multiple stems they are too burdensome for quail to use. Half-cutting transforms the mesquite tree into a refuge for quail from avian predators and high temperatures. Dr. Dale Rollins explains how this technique is used on the Rolling Plains Quail Research Ranch to benefit quail in the video below.

When you produce a tree with 40 varieties of fruit, it would be pretty accurate to assume that there will be something for everyone to enjoy. If you aren’t a fan of plums, try an apricot, or a cherry. Like the tree with so much variety, mesquites can be enjoyed by other species as well. Understandably, brush and shrub species occupy a lot of space that could be populated by more favorable forage, but they do serve more than one purpose. Tyson (2010) suggested that mast producing plants provide a greater abundance of food items for quail, grassland species, and predators of quail. During this study which took place in the Rolling Plains ecoregion of Texas, mast from prickly pear and mesquite ranked 2nd and 3rd, respectively, in the diet of coyotes. Thus, the importance of mast producing trees and shrubs to both quail and coyotes in this part of the state should not be underestimated.
So the next time you are considering what to do with your pasture of mesquite, think about the tree of 40 fruit and gauge whether you too could find an adaptable management plan that incorporates these invasive trees. You just might find that mesquites in moderation are not so bad.
