Beaver Marsh Trail - #2 - Native Plants



 

What is a Native plant? What is so special about native plants?

Native plants are plants that can grow in an area naturally without human influence or by being brought from another region in a specific location. They often serve as the foundation for ecosystems including wetlands and have important interactions with other members of an ecosystem. Most of the times, this interaction is being a source of food for many animals. They can convert solar energy into a form that is useable by plants and other organisms and this useable form is transferred throughout the ecosystem when animals eat plants or other animals. Native plants also help to improve the aesthetic of an environment and help make it unique from other regions.

What is an indicator plant?

Plants can be used to indicate the conditions of a local ecosystem. For example, Q. stellata is a tree species that does not grow well in sterile, sandy soil. Evergreen forests only grow in areas with high rainfall throughout the year and grasslands can be found only in regions where it rains mainly during the summer. Species like Utricularia, Wolffia grow only in very polluted regions and plants like Agrostis, Eupilobium, Pium Plum usually grow in areas with frequent wildfires.

Why are non-native plants a problem?

While native plants are usually very important for an ecosystem, non-native plants, which are often invasive plants, can be extremely harmful. Not only do they compete for nutrients and other resources but they can disrupt an ecosystem. Invasive plants are currently one of the biggest threats to biodiversity because they are much more capable of utilizing native sources than native plants and though can make an area filled with many different plant types become an area with only one or two plant types.

What can I do to help promote native plants?

Non-native plants pose a big threat to local ecosystems but their harmful impacts can be reduced. One way to do so is to simply verify that the plants you use are not a non-native invasive species. Planting native plants can help restore the function and health of an ecosystem. Another way to help is by volunteering at parks or other wildlife areas to help remove any non-native plants.
