What Determines If A Plant Or Animal Species Is Invasive
This post has been updated to include additional, relevant information about native and invasive species.
Yous may have heard the termsnative,non-native andinvasivein the context of plants or animals that live in Northern Indiana. But the pregnant of these words might be disruptive, too as how their differences impact the health of our natural resource.
Let'due south start by defining our terms…
- Native: a species that originated and developed in its surrounding habitat and has adjusted to living in that particular environment. (It can become ambitious, like to an invasive species.)
- Invasive: a species of plant or animal that outcompetes other species, causing damage to an ecosystem.
- Non-native: a species that originated somewhere other than its current location and has been introduced to the area where it now lives (also chosen exotic species).
Did yous know?
Although not native to our state, the peony is Indiana's state flower. "It's a non-native plant that has been cultivated," said Brad Clayton from Clayton Garden Center. "Information technology's been here long plenty and doesn't cause economical or ecological harm." The peony, once not-native, is now a type of naturalized plant.
Meet our state flower and tree
"Native plants are ones that evolved and adapted to a specific area or region without human intervention," explains Brad Clayton, expert gardener from Clayton Garden Eye. In general, a native species will produce robust foliage and/or blooms once established, and quickly attract critters like butterflies and insects. They survive in both dry and rainy weather without suffering.
Aninvasive found will spread and forestall other plants from growing. "They cause either economic or ecological loss," Brad noted. "This can happen by reducing crop yields in agricultural production, or in the case of forestry product, the reduction of desirable species needed for timber." Although beautiful in their own way, they dominate their ecosystem and don't provide the nutrients needed by native insects and animals.
Not-native plants share qualities of both: they produce leaf or blooms and don't take over their habitat. Only they're frequently not adjusted to the environs, and require more than care than native plants. If a non-native stays around for long enough, it's labeled a naturalized establish. (Like the peony!)
Sometimes the differences go blurred. For example, you can have anative plant that becomes ambitious (but non invasive) as it takes over your flowerbed. In the context of a lake, blue-green algae is a native species that causes bug similar an invasive would.
You can besides havenon-native species that stay in i spot and don't becomeinvasive. Well-nigh landscaping plants (especially those planted annually) fall into this category. Although non native, they also don't disrupt their environment.
Examples of invasive species
These are common aquatic and terrestrial invasive species found in Kosciusko County.
Zebra mussels, or more specificallyDreissena polymorpha, are a species of freshwater bivalve. They are native to the Black Sea and Caspian Sea in eastern Europe, merely made their way to the U.s. in the 1980s in the ballasts of ships. They are prolific and can quickly clop pipes and line shorelines with sharp shells.
Starry stonewort is an aquatic invasive species that can grow in water anywhere from a few inches to ix meters deep. Information technology prefers hard h2o and can tolerate low-light conditions. At it'south worst, the invasive can out-compete native species and create dumbo mats on the surface.
This invasive shrub is found in woodlands and in landscaping. If allowed to grow without pruning, they become large and dumbo, preventing light from reaching other plants. They grow best in "platonic" weather: moist, well-drained soil and part-to-total sun.
Garlic mustard is a bright green, leafy plant that has minor white blooms. It tin apace re-seed and spread through big swaths of woodland. It can hands oversupply out native species, and it's hard to eradicate one time established.
Landscaping with native plants
The ideal native establish garden volition have a counterbalanced variety of species, much like the landscaping around the Lilly Heart's dwelling house in the Dr. Dane A. Miller Scientific discipline Complex.
"The simplest way to comprise native plants into an existing landscape is to merely plant them," Brad says. "Look for nativars, which are native plant species that have been cultivated by humans to be more desirable in landscapes."
For example, purple dome New England aster. "Majestic dome only gets xviii inches alpine and i-ii feet wide, compared to its native counterpart which is iv-6 feet alpine, and 2-3 anxiety wide," Brad explains. Both varieties are first-class nutrient sources in the fall for pollinators looking to stock upwards before winter.
In the Lilly Middle's native gardens, yous tin detect purple dome aster, swamp milkweed, purple coneflower, blue flag iris, wild quinine, blueish-stemmed goldenrod and black-eyed susans, just to name a few! Each establish is adapted to keep the others in bank check and also provides habitat and food for many kinds of insects and animals.
Many local nurseries go along native plants. Achieve out to them today!
From land to water
How you manage your landscaping can have a big influence on the health of local waterways, including lakes, rivers and streams. Thoughtful landscaping helps foreclose too many nutrients from entering the water and producing weeds and algae blooms!
Why does that matter?
