Support selective removal of invasive plants

SAVE MAUMEE GRASSROOTS ORGANIZATION·TUESDAY, JUNE 26, 2018

Diversity is Earth’s antibiotic. The new forestry technique is to remove the invasive species in wild areas, and the natives will return.  One does not even have to plant any other plants (although it helps)!  To have the natives return, one just needs to remove the plants that do not belong and nature will take care of the rest! Humans have introduced these non-natives and it will take humans to help get them under control.

The native species are better adapted to our climate and have longer taproots to live through drought of flood.  They have adapted over millions of years and this will help keep them hardy and help them to make it through stress caused by climate changes.  Animals in the specific region go hand-in-hand with the plants and have also taken a million years (or so) to adapt and become dependent on the native food sources and habitat these native species of plants provide.  Invasive species are not suitable to our local adapted wildlife. 

Be selective in your removal though, because different species of plants should be identified and categorized differently…for example:

* Natives – desirable and present previous to European decent and should be protected.  Here are some we plant: http://savemaumee.org/native-vegetation/ 

* Aggressive – present previous to European decent, BUT will aggressively outcompete other more particular native species and not necessarily desirable, but not invasive. 

* Naturalized – probably not present to European decent, and have the potential to eventually be invasive in the future, but are not considered invasive and currently have beneficial qualities present currently.

* Exotic – not present previous to European decent and human activity has moved the species here from its indigenous place of orientation. 

* Invasive – NOT present previous to European decent, and NOT desirable and SHOULD BE REMOVED in that area as common practice to land management. Invasive species that were not here previous to European descent were introduced by humans.   Invasive species outcompete other plants for light, space, water, and nutrients in the soil and some exude chemicals to kill other plants that may be growing near them.

*Prohibited and restricted is also INVASIVE– plants that do direct harm and SHOULD be removed from all of the root to the tip, and all flowers and seeds, and put in a bag and thrown in the trash.  

Why are invasive species so bad? 

*Competitive advantage over native plants for sunlight, moisture, space and nutrients in the soil, spreading by roots and seed and results in ability to further dominate areas. 

* Competes with native plants for pollinators, resulting in fewer seeds set on native species.

  • Example: Black swallowwort, (recently identified in Fort Wayne, IN) kills monarch butterflies because it is a close enough relative to our native milkweed that monarch lays eggs on this plants, but the caterpillars die because it is not the right food source.  
  • Example: Asian Honeysuckle (all 140 non-native species) do not bear fruit that the birds can digest properly.  The fruit is carbohydrate-rich and does not provide migrating birds the high-fat content needed for long flights. So native species of birds can starve to death with a full belly. It would be comparable to humans eating lawn-grass – we cannot metabolize lawn-grass for vitamins and nutrients our bodies need.It is suspected that honeysuckles may produce allelopathic chemicals that enter the soil and inhibit the growth of other plants around them.

So the DNR is creating a document of the worst plant offenders and are working to remove these species from store shelves….which is a great idea that Save Maumee supports!
