Got (Native) Trees?

 

As housing lots get smaller and smaller, more native trees are cut down for those developments than are planted back. It’s a trend that we need to reverse. And we can do that with our own actions: plant more native trees.

Sweetgums support life!

Whether it is a pristine woodland lot or a scraggly former cow pasture with early-succession trees, these areas contain plants – maples, sweetgums, oaks, tuliptrees – that support our native insects and they get wiped out when development comes through. What is planted back are rarely plants that sustain our insects. We usually get turf grass, exotic shrubs, and one tree in these new ¼-acre yards. The tree might be a native maple, but it just as easily could be an exotic elm or crape myrtle.

The population of butterflies and birds just took a dive in the new area because the carrying capacity of the area is diminished. We know from research that birds need about 70% native vegetation in order to stay at reproducible numbers (maintain the same population). Large trees like oaks, sweetgums, maples and tuliptrees significantly contribute to those kinds of numbers.

Friday was Arbor Day in Georgia. I write about this almost every year (and my post in 2022 was a good summary of why we have it in February and why native trees matter) because it is always a good opportunity to remind people of the importance of native trees. Last year, I specifically profiled red maple (Acer rubrum) for my Arbor Day post because of its statewide profile.

I hope you will take some time to look at what you have in your yard and consider adding a new native tree to increase your biodiversity. You might even consider replacing any non-native tree that you have already.
