The warm winter is making it easier for invasive plants to grow, spread and thrive in 窪蹋勛圖厙 and across New England.
According to the 窪蹋勛圖厙 Invasive Plants Council, the state has more than , which can arrive from more southern states through bird migrations and the wind.
Bonnie Burr with UConns College of Agriculture, Health and Natural Resources, said those invasive plants are thriving more because of warmer temperatures, sunlight and moisture.
When [the] growing season gets warmer, gets longer that just gives our invasive plants a greater opportunity to expand, Burr said. We see them become much more dense in terms of how they infiltrate within our native plant populations.
Burr said her department is still seeing too many invasives that have not died off this season. She said curbing invasive plant growth requires temperatures dropping below freezing for at least 10 days.
But freezes have been hard to come by this year. Last month was and the , according to climate reports from the National Oceanic and Atmospheric Administration.
Randy Prostak, a University of Massachusetts Extension weed specialist, said the warmer weather could lead to longer growing seasons for invasive plants and cause them to spread more quickly.
The bigger the plant gets, the healthier it gets, the more likely its going to be able to flower and produce more seed, which is going to drive that forward, Prostak said.
, according to the 窪蹋勛圖厙 Invasive Plant Working Group (CIPWG). The group has identified species like common reed and garlic mustard . Japanese honeysuckle and Japanese barberry are also among plants of concern, according to the CIPWG.
Invasive plants are benefiting tick populations
A said invasive plant species like Japanese barberry can give ticks an unnaturally beneficial habitat.
Dr. Megan Linske with the 窪蹋勛圖厙 Agricultural Experiment Station said she has seen how Japanese barberry is benefiting populations of deer ticks in the state.
It tends to leaf out really early, capitalize on the sunshine and the warmth that comes with these warmer winters, Linske said, adding that it creates dense thickets that many tick species want to be in for a long time while seeking a host.
Burr, with UConn, said invasive plants easily acclimating to the warming climate raises a red flag.
Its their ability to get in and really create havoc, Burr said. That really, really has us concerned about how invasives are coming in and staying.
To report an invasive plant species sighting, the 窪蹋勛圖厙 Invasive Plant Working Group is asking people to email info@cipwg.org with photographs and details of the finding. More information is outlined .
