ميشيغان الأكثر غير المرغوب فيها
لم تنتشر هذه الأنواع الخمسة الغازية إلى ميشيغان، لكنها تسببت في مشاكل في أجزاء أخرى من الولايات المتحدة نحن لا نريدهم هنا ويمكنك المساعدة!
ما هي الأنواع الغازية؟
نوع غير أصلي والذي يسبب إدخاله، أو من المحتمل أن يسبب، ضررًا اقتصاديًا أو بيئيًا أو ضررًا على صحة الإنسان.
| ASIAN CARP (BIGHEAD) (Hypophth halmichthys nobilis) | RED SWAMP CRAY (procambards clarki) | KUDZU (Pueraria lobata) | WATER LETTUCE (Pistia stratiotes) | Hardwood trees, particularly maple, birch, elm, willow, buckeye, and horse chestnut; maple is the most common host | |
|---|---|---|---|---|---|
| LOOK FOR THEM HERE: | Open waters | Marshes, swamps, ponds, and slow-moving rivers and streams | Forest edges, abandoned fields, and roadsides. | Ponds, lakes, ditches, and slow-moving rivers and streams | ASIAN LONG-HORNED BEETLE (ALB) (Anoplophora glabripennis) |
| IDENTIFY THEM WITH: | Weighs up to 90 pounds. Very large head and toothless mouth. Eyes sit below the mouth | Dark red with raised bright red spots. 2 to 4 inches long | Leaves look just like a bean leaf - a single trifoliate leaf is made of 3 broad, slightly pointed leaflets with golden hairs. Leaves can be as large as 10 inches across. Seeds are in a pod, looks like a pea pod | Thick and ridged leaves with short soft hairs eaves form a rosette. Feathery roots grow up to 32 inches long and hang below the water surface. | - Long antennae (male beetles have antennae longer than their bodies - Shiny black body with white spots - Six legs, may have blue feet - 1-1½ inches long |
| INTERESTING FACTS. | Bighead is just one kind of Asian carp. There is also the black carp, grass carp and silver carp. | An important aquaculture species in the southern states - they make up the majority of crayfish consumed worldwide! | Kudzu can grow one foot a day! | Water lettuce is sold as an ornamental plant for water gardens and aquariums. But if it gets into the wild, it becomes Invasive. Small groups of water lettuce were found in southeast Michigan and south of Lansing; however, the Michigan DivR removed the plants by hand. | Pay attention to trees, especially maples, with dying branches - Look for 3/8 inch, perfectly round exit holes in bark of large branches or the trunk |
| WHY WE CARE: | Hurts native fish either by damaging habitat or consuming mass amounts of food. Poses a threat to native high such as walleye, yellow perch, and lake whitefish. Can create economic and ecological damage to entire Great Lakes region | - Competes for food and habitat with native water wildlife. Feeds on aquatic plants, snails, insects, fish and amphibian eggs. Eventually forces out native crayfish populations, and may also impact fish populations. | Covers all other plants - even trees. and eventually is the only plant left in the area. Can harbor soybean pests and disease. which could spread to crops. Creates mats that c can be 5 feet deep, making the area unusable tor outdoor recreation | - Forms dense mats that make it difficult or native plants to grow. Disrupts fish communities. Affects water quality er recreation like boating | Kills trees - Larvae feed in tunnels in the wood of tree branches and trunks, eventually killing the tree - Maple trees are the ALB's favorite host, and there are more than 1 billion maple trees growing in Michigan! |
