Landscape uses - Feature Plant, Shade Trees Water requirements - Average Water, Ample Water This tree contains very sweet sap that can be distilled to create syrup that equals that of sugar maple. Further north its bark becomes home to mosses and ferns. Big-leaf maple creates habitat for wildlife, has high ornamental value and easily naturalizes. It is a good choice for expansive rural home sites with high water tables and perennially wet conditions in the west. Grow this tree in sites with good moisture and partial sun. The change to gold begins with the cooling of late summer nights. The new leaves are bright yellow green and darken through summer. Trees produce inconspicuous wind-pollinated flowers in the early spring, which mature into winged seeds called samaras. The big leaves can be truly enormous and are borne heavily on upright stems. In warmer regions it grows at the base of north-facing slopes where perpetual shade and summer dampness support its need for moisture during the growing season. It is nearly always found in conjunction with streams and creeks. It is counted among the few true western native maples, its range extending from foothills of Alaska to southern California and eastward to the Sierra Nevada Mountains. When asked what can be done to stop or slow down the worms' spread, Görres says he and his team are working on environmentally safe ideas such as using fungi or insecticidal soaps.īut he adds that it's difficult to find funding for projects to take down earthworm populations - another consequence, he said, of their street cred.This immense deciduous tree bears the largest leaves of all maple species and is spectacular when it turns golden in the fall. They also have a milky white or gray clitellum - the band that many earthworms have - that is flush with the rest of their body. through the domestic market, both through the horticulture industry and through their sale as fish bait.Ĭrazy worms can be identified by a few unique qualities, starting with their behavior. But it wasn't until fairly recently that crazy worms were seen as becoming established, and Görres and other scientists say they seem to be spreading more now. Then, in the 1800s, the new type of worms arrived from Asia. Cotton FarmersĮarthworms such as nightcrawlers came to the region later, arriving along with colonists from Europe. Short Wave A Pesky Rumble: Pink Bollworms Vs. "Without that protective leaf litter and duff layer, they become very stressed, and they're more susceptible to insects and diseases, and they're less likely to grow very fast," he said. "They tend to really impact maple trees," he said, particularly because those trees tend to have shallow roots. What about my syrup?Ĭrazy worms' impact on maple syrup could be "severe," Fish told Maine Public Radio. And because they mature in just 60 days, two groups of offspring can hatch in a single season.Ī number of states, including Maine and New York, have banned crazy worms outright. They can reproduce asexually, through parthenogenesis. The Asian worms also have biological advantages. In these images showing two stands of sugar maple trees, the one on the left has not been invaded by Asian crazy worms, and the one on the right has. But in the context of the northern forest, they are relative newcomers that have the potential to have huge effects." "I call earthworm invasions 'socially cryptic,' " Görres tells NPR, "because folks think of earthworms as the good guys - and maybe they are in certain ecosystems. "The street cred that they have is hiding the invasion," Josef Görres, a soil scientist at the University of Vermont, says of the worms. But in the Northeast, experts say invasive "crazy worms" from Asia are creating havoc in forests - and they say the unusual worms are a danger to animals and plants, and especially to sugar maple trees. Josef Görres/Plant and Soil Science Department University of VermontĮarthworms are often seen as a welcome presence in gardens, and even on fishing hooks. The worms can thrash around so violently that they can jump out of a person's hand. Crazy worms - an invasive species from Asia - pose a threat to forests, scientists say.
