Invasive Species
Phragmites Australis
Phragmites Australis
Phragmites Australis
- Phragmites is a type of wetland grass that is native to many parts of the world.
- It has tall, thick stalks that can grow up to 15 feet in height.
- Phragmites spreads through underground rhizomes and seeds that can regenerate into new plants.
- When phragmites is introduced to a new area, it can spread quickly and outcompete native plants for resources.
- Phragmites can also alter the chemistry of the soil, making it less suitable for native plants.
- Phragmites make it more difficult for fish and other aquatic animals to move through the water, which can affect their ability to find food and reproduce.
- To prevent the spread of phragmites, it is important to clean boats and equipment before moving them between bodies of water.
- If phragmites has already invaded an area herbicides is the best treatment.
European Frog-bit
Phragmites Australis
Phragmites Australis
- Frogbit is a type of aquatic plant that is native to Europe and Asia.
- It has round leaves that are about 1-2 inches in diameter and small white flowers.
- Frogbit spreads through seeds that can float on water.
- When frogbit is introduced to a new area, it can spread quickly and outcompete native plants for resources.
- This can harm local ecosystems and the wildlife that depends on them.
- To prevent the spread of frogbit, it is important to clean boats and equipment before moving them between bodies of water.
japanese Knotweed
Phragmites Australis
japanese Knotweed
- Japanese knotweed is a type of herbaceous plant that is native to Asia.
- It has hollow stems and produces small, white flowers.
- Japanese knotweed spreads through underground roots and stem fragments that can regenerate into new plants.
- When Japanese knotweed is introduced to a new area, it creates a monoculture and outcompete native plants for resources.
- As a result, the plant can reduce the diversity of plant species in an ecosystem and make it less suitable for wildlife.
- It is important to avoid planting Japanese knotweed in gardens or landscaping, as this can allow the plant to spread to natural areas.
- If Japanese knotweed has already invaded an area, there are several methods that can be used to remove it, such as hand-pulling, herbicides, or mechanical removal.
Giant knotweed
Giant knotweed
japanese Knotweed
- Giant knotweed (Fallopia sachalinensis) is an invasive plant species native to Asia.
- It grows rapidly and can reach heights of up to 10 feet (3 meters).
- Giant knotweed has thick, hollow stems with large, heart-shaped leaves and small white flowers.
- It spreads quickly through underground rhizomes (roots) and can form dense stands that crowd out native plants.
- Giant knotweed is found in many countries around the world, including the United States, Canada, and Europe.
- It is a serious threat to natural habitats and can cause damage to infrastructure such as roads and buildings.
- Control measures for giant knotweed include manual removal, herbicides, and the use of specialized knotweed-eating insects.
- It is important to properly identify and manage giant knotweed to prevent its spread and protect natural habitats.
SB-CISMA
Giant knotweed
Spongy Moth
Arenac Conservation Districts partners with other communities in the Saginaw Bay area through the Saginaw Bay Cooperative Invasive Species Management Area (SBCISMA) to work together, share resources and promote outreach and education through a grant from the MDNR invasive species grant program.
Spongy Moth
Giant knotweed
Spongy Moth
- The spongy moth is a species of moth native to Europe and Asia.
- It was introduced to North America in the late 1800s and has since become a major pest of trees and forests in the United States and Canada.
- Spongy moths have a wingspan of about 1.5 to 3 inches (3.8 to 7.6 cm). The wings of the males are typically white or light brown, while the females have dark brown or black wings.
- Spongy moths are known for their voracious appetites and are capable of defoliating entire trees and forests.
- They prefer to feed on the leaves of hardwood trees, such as oak, maple, and birch, but will also feed on conifers.
- Spongy moths are most commonly found in the northeastern and mid-Atlantic regions of the United States.
- Control measures for Spongy moths include the use of insecticides, pheromone traps, and the release of natural predators, such as birds and insects.
- It is important to monitor for and manage Spongy moths to prevent significant damage to trees and forests.
