National Park Service (USA) has a complete site with hundreds of links dedicated to invasive species present in the National Park system [1].
Plants:
Key Online resources:
- Invasive Plant Atlas.org [2] [National Park Service http://www.nps.gov] (search park name and then invasive species for a list)
- The National Park Service (USA) has also provided downloadable PDFs with details and pictures for hundreds of invasive plant species by region.

In the United States, the story usually goes something like this: Originally brought from (China, Japan, India, etc.) as an ornamental or decorative plant. Escaped, and began to take over the area.
Other plants were brought over purposefully to aid in erosion control, plant control, or even insect control. However, the invasion of the new species usually far outweighed the benefits.
Some invasive plant species include:

Challenge the young people to collect (if collection is allowed) items as they go on a hike or walk through a deciduous forest. They can share their stories upon their return.
An OBJECT LESSON is defined as a type of story which involves a visible tangible object that the speaker displays during her/his talk.
Here is one example of many:
Fall Colors: The fall colors of the deciduous forests are famous around the world! The green chlorophyll in the leaves, which uses the suns light to make energy for the leaf, will become toxic to the tree if it remains and the temperatures get to cold. So the leaves break down the green-colored chlorophyll leaving the yellow and orange-colored carotene pigments, which have been hidden all summer by all the green chlorophyll. The red pigment of maple leaves is caused by anthocyanin. This red pigment is added in the fall at about the time the green chlorophyll disappears. While the colors are beautiful, one can’t help but wonder why so much energy is used to make all that red pigment which will last for only a couple of weeks and then be of no use when the leaves fall off?
Scientists have now discovered at least three possible purposes for the anthocyanin in fall. Red repels aphids! Seeing their favorite tree turn red makes them jump off and find some other leaf to eat! So once a year the anthocyanin acts as an insect repellent. Secondly, when the leaves fall off, the anthocyanin is absorbed in the soil around the base of the tree and acts as an herbicide. Other trees are less likely to sprout and grow and compete with the mature tree! The third reason for anthocyanin is that it can help the tree trap the sun’s energy when the chlorophyll is gone thus extending the growing season a bit longer.
God often does things that may seem strange to us but He always has a purpose for what He does. He acts on our behalf; each act for a functional purpose. But He also adds beauty to the work He does. Enjoy the fall colors and be reminded that He is in control.

Tip for earning from home during the pandemic | |
Requirements 11b, d, and e can be done at home. Requirement 11a can be done if the trails in your area have not been shut down and if you maintain social distancing protocols during your visit. Requirement 11c could be possible with a virtual visit. |

Many hiking trails offer trail maps or sign posts with tree names and details mounted on or near the tree. Research whether your area has such a trail. Another option is to have a naturalist guide you on a hike to identify deciduous tree species.
