The silver lining to the recent unrelenting cold snap is that many types of invasive insects can’t survive the frigid conditions. These invasive insects include the emerald ash bore, known for killing millions of trees in the last decade, and the gypsy moth, which eats the leaves of trees, such as those used to grow agricultural crops. All told, the damage by these tiny pests costs the US government and homeowners billions of dollars in damages each year. The good news is that reports show that the recent cold snap may have eliminated 80-100% of some of these pests in certain areas.
Unfortunately, there is also, of course, some bad news. The same climatic changes that have contributed to the polar vortex are also predicted to ultimately cause milder winters in the eastern United States, so the insects’ geographical range will expand further north from where it was once restricted by colder temperatures. The cold may also be killing parasitoid wasps, one of the few predators for the emerald ash bore. This means that when temperatures rise again this spring, the emerald ash bore may be able to bounce back in even greater numbers. Ecological systems are complex and highly interdependent, so it is rare that something will change just one piece of the system; the response to climate change by these invasive insects may have additional unpredicted results because of unidentified feedbacks (for instance, how might climate change affect their food sources or the other insects with whom they are in direct competition?).
Climatic changes won’t just affect invasive insects, but will also influence invasive plants, like the phragmites, or common reed, which we often encounter at Freshkills Park. Recent studies indicate that phragmites will thrive under increased carbon dioxide levels, meaning that the plant overgrowth will become even more of a problem as climate change progresses. While we have taken some steps to control the ever-present phragmites at Freshkills Park, even using goats in one restoration project, the interaction of climate change with these invasive species will pose a challenge for years to come and demand the ecosystem to adapt.
Our third annual Sneak Peak event is just one month away!
Sneak Peak is a rare opportunity to go inside the park and preview the incredible transformation of the site. This year’s event will take place on Sunday, September 23rd, from 11 am to 4 pm, and will feature all sorts of fun things to see and do, including birdhouse building, kayaking, kite-flying, bike riding, pony riding, mural painting, bag sewing, instrument making, and much more. Plus, the famous phragmites-munching goats will be making a special return appearance! But of course, the main attraction, as always, will be the breath-taking beauty of Freshkills Park.
If you haven’t made it out to see it for yourself, this is your chance.
For more information on getting there, including free shuttle buses to and from the Staten Island Ferry St. George terminal and a free round-trip New York Water Taxi ride departing from the Battery, click here.
Freshkills Park bids a fond farewell to the herd of goats who have spent the past few weeks “mowing” the invasive phragmites at the North Park Wetlands Restoration Site. This quirky group of goats, with names like Mozart, Haydyn and Van Goat, not only did a fantastic job of removing the vegetation from the site, but also seemed to thoroughly enjoy their pleasant surroundings at Freshkills Park. The herd even welcomed a new member during their stay, with the birth of an adorable baby goat a few weeks ago (see our previous post about this new “kid” on the block). For more photos of all the goats in action, be sure to look back at all of our Facebook and Flickr albums.
Although the goat crew will be missed, we are thrilled to be able to welcome them back to Freshkills Park for our annual Sneak Peak event on Sunday, September 23rd, where the herd will be featured at the Petting Zoo. Stay tuned to our blog and Facebook pages for more exciting Sneak Peak updates!
