It’s hard to resist the Hans Christian Andersen fairy tale, when an ugly duckling grows into the most beautiful swan in the pond.

Unfortunately, New York State’s largest bird can be aggressive to humans, and their voracious appetites often disturb local ecosystems, displacing native species.

Mute swans eat up to eight pounds of submerged aquatic vegetation, including eelgrass, daily. They sometimes completely uproot plants, and often, adult swans will uproot more plants than they actually consume.

A disturbing study published in Feb. 2019, found that more than 40 percent of the world’s insect species could go extinct over the next several decades due in large part to habitat loss, with chemical pollutants, invasive species and climate change as additional causes.

Now, a new study, published in the Feb. 7, 2020 journal, Science, makes a case for climate change as the principle driver of the potential extinction of bumblebees. Scientists said that observers in North America are nearly 50 percent less likely to see a bumblebee in any given area than prior to 1974.

Using a massive dataset, scientists found that bumblebees are less abundant in areas that have become hotter or have experienced extreme temperature swings in the last generation. The researchers concluded that “climate chaos” is the primary driver in the decline of bumblebees. Species are being pushed beyond temperatures they can tolerate, said the scientists.

According to National Geographic, bumblebees are suited to cooler weather, with fuzzy bodies and the ability to generate heat while flying. The last five years were the hottest ever recorded in the 139 years that the U.S. National Oceanic and Atmospheric Administration has tracked global heat.

Honeybees are critical to the propagation of nuts, fruits and vegetables and account for more than $15 billion in the U.S. economy.

There is an open water dump site less than three miles off the northwest coast of Fishers Island, and wheels are in motion to use it as the dumping ground for 890,000 cubic yards of contaminated, fine-grained muck dredged from the bottom of the Thames River. The dredging will make way for a new class of ballistic missile submarines to be built at Electric Boat in Groton, Conn.

Nov. 29, 2019 was the final date for public comment on the proposed dredging. FIConservancy has a long history of objecting to dumping toxic dredge spoils at the head of the Race, where waters are shallow and tidal currents are among the strongest on the East Coast.

FIConservancy President Tom Sargent mailed a letter to the New York State Department of State expressing serious environmental concerns and explaining that our objections have never been about the fact of necessary dredging, rather where the dredge spoils will be dumped.

The Asian jumping worm, which can grow to eight inches, is identified by the whitish band that mostly circles its body near its head.

Dianne Crary in October reported the presence of “a lot” of invasive Asian jumping worms on her property along Equestrian Road. Unlike the familiar earthworm, which burrows into the ground, this Asian invader, when disturbed, writhes and scatters across the surface of the soil. If touched, it thrashes wildly and may shed its tail.

Living on the surface in woodlands, Asian jumping worms quickly devour fallen leaves and other organic material, turning the surface into loose soil resembling coffee grounds. The loss of leaf litter destroys long-lasting nutrients vital for the survival of trees. Additionally, altered soil inhibits the establishment of tree seedlings and is inhospitable to many native plant species.

Asian worms reportedly have reduced leaf litter in hardwood forests by 95%. A naturalist observed an infested forest in Cortland County, New York, and said that “it was almost entirely bare soil.”

As with so many invasive species, these worms are adaptable and difficult to stop. They are parthenogenetic: they can reproduce without fertilization. The introduction of a single individual is enough to launch a jumping worm invasion. The worms have an annual life cycle. They die in the fall, but leave tiny cocoons that winter in the soil.

What to do? According to the Cornell Cooperative Extension of St. Lawrence County, “Asian worms are commonly spread through the horticulture trade, both in containerized plants, and especially mulch, which they love. Check bulk mulch before purchasing, and maybe think twice about getting fill delivered to your property.”
