TURF WAR: THE BATTLE BETWEEN INVASIVE AND NATIVE PLANTS

Everyone needs a home. For pollinators, and every other organism, that home, or habitat, means food, water, shelter and space. But what happens when our Texas pollinators can’t find a home? Well, it’s fairly simple; their numbers decline, often dramatically. And while there are many causes of habitat loss, some of the biggest culprits are non-native invasive plants.

One of the easiest and most effective ways for you to help our native pollinators is to avoid planting non-native vegetation and to replace any that currently reside in your landscape with natives. The types of plants, shrubs and trees you choose for your landscape is critical as they are primary providers of both food – pollen, nectar, leaves and seeds – and shelter. Many insects acquire most of their water from the vegetation they eat. Our Texas butterflies depend on Texas native plants for reproduction, laying eggs on the leaves. When the eggs hatch into caterpillars, those young butterflies eat the leaves to sustain themselves as they grow large enough to make their chrysalis, later emerging as adult butterflies. Many pollinators have evolved with native plants, both adapting to the local climate and growing season.  Non-native plants may not provide pollinators with enough nectar or pollen, or the plants may be inedible to some caterpillars.


Native plants play a critical role in the survival of pollinators

The existence of these plants impacts more than just pollinators. Many non-natives become invasive, out-competing existing natives for soil nutrients and crowding them out. Some of the worst offenders in our community include air potato vines, Chinese and Japanese privets, Japanese honeysuckle, Nandina (often called heavenly bamboo), elephant ears, and Japanese climbing fern. While some may look good in our yard and can be effectively managed, their seed or runners often escape into neighboring greenbelts, pathways and open spaces. The resulting loss of native vegetation and habitat value in these areas is never pretty.
