Our June 2 volunteer work session will be held at the Armstrong Preserve on June 2 at 10am-noon (link to map). Participants will receive tips on how to identify invasive plants that negatively affect forest and watershed health. Learn to protect native ecology in your own backyard by removing or controlling the spread of these undesirable plants, including Asiatic bittersweet vines, Japanese barberry, wineberry, and burningbush. Join our Garlic Mustard Challenge and pull this tasty but environmentally noxious weed by the pound to make your own pesto! We will meet at the kiosk and work nearby. Please wear long pants and sleeves to protect your skin from ticks and thorns, and bring thick leather gloves and a shovel if you have them. We will have some gloves and tools to share. For more information or to register, please contact Krista at email@example.com or 914-205-3533.
Invasive species are a major threat to biodiversity worldwide, second only to habitat loss. In this enlightening summit in Ross Hall, five experts share their hard-won insights about best practices to manage and restore ecosystems, and engage in audience conversation about how to establish goals, prioritize, take action to implement projects, and overcome challenges to achieve long-term success in both small- and large-scale sites.
Topics and Speakers:
Removal is Not (Usually) Enough!
Paddy Woodworth, award-winning Irish journalist and author of Our Once and Future Planet
Restoration Success in a Densely Urban Environment
Kristy King, Director of Natural Areas Restoration and Management for NYC Parks
So Many Weeds, So Little Time
Art Gover, Research Support Associate for the Penn State
Lessons from Urban to Suburban Environments
Tate Bushell, Director of Stewardship with the Westchester Land Trust
Jessica A. Schuler, Director of the Thain Family Forest at NYBG
Co-presented with Lower Hudson Partnership for Regional Invasive Species Management:
Five new student volunteers stayed warm by working hard at our first Saturday Volunteer Work Session of the year last week at the Clark Preserve. We worked together to clear Japanese barberry and other invasive plant species from an area near the entrance to the preserve, on Autumn Ridge Road in Pound Ridge. The students were able to draw connections between what they saw and learned about in the forest, and what they have in their yards at home. They asked important questions: “how did invasive species get here?” (They were brought in by nurseries for sale as landscaping plants, in many cases.) And, the kids want to know what is edible, trying out garlic mustard and onion grass and black birch. We talked about making syrup from Sugar maples, and how you can know you are looking at a maple even at this time of year (by the buds and pattern of branching). Curiosity flows freely in the outdoors.
We are grateful for the assistance of volunteers in maintaining the health of this seventy acre forest, and we look forward to spending more time out on the land this season. Join for our next Saturday Volunteer Work Session on April 1 at Richard’s Preserve on Honey Hollow Road, 10am to noon. We will be making improvements to the entrance to the preserve including installation of a water bar to direct road runoff out of the trail. Please bring a shovel if you have one, and wear long sleeves and pants for protection from thorns.
April is Invasive Pest and Disease Awareness Month, and a task force of the United States Department of Agriculture seeks to raise awareness of the threat of invasive species to ecosystems, the economy, and to our own well-being. Their website has excellent photographs of two main villains in our area: the Asian long-horned beetle (ALB) and the Emerald ash borer. It says, “The ALB has the potential to cause more damage than Dutch elm disease, chestnut blight and gypsy moths combined, destroying millions of acres of America’s treasured hardwoods, including national forests and backyard trees.”
Citizen help is needed to stem the spread of known populations and to prevent new ones. Hikers and landowners have reported several new occurrences, and if caught early enough, some cases can be eradicated. In New York, the state has imposed a quarantine on moving firewood and certain other wood products from one location to another, and with good reason. The map on the right shows the known distribution of the Emerald ash borer in New York.
We have been hearing about invasive species quite a lot in our local news in Pound Ridge. Earthworms from Europe aredepleting our soils and forest health, Mute swans (also from Europe) alter water quality and displace native wildlife, and our sources of food for birds and insects are in decline due to competition from non-native species. We seem to have an ecosystem in peril, with the good, the bad, and the ugly in conflict. What can we do? One thing we cannot do is expect Mother Nature to fix the problem. Adaptation and ecosystem balancing occur on such a long time scale that to wait is to risk massive extinctions and the loss of ecosystem services like clean water.
We can, however, draw upon the power or nature to right itself. A healthy ecosystem naturally resists biotic invasion from pests, whether they be animal or plant, because all of the niches in the system are filled. It is difficult for an invader to gain a foothold among the fierce competition of a thriving, co-adapted community. The plants and animals that do become invasive were often brought here intentionally and sold for their pest-resistant properties (because our wildlife cannot eat them).
Recommendations: We must all do our part to support diversity in native ecosystems by protecting certain areas as wildlife preserves and ensuring that those areas are connected by corridors. This is a major concern of the PRLC. We can also greatly expand the boundaries of protected land by choosing to landscape public and private properties with native plants to whatever extent possible, and in place of lawn.
To learn more about the relationship between native plants and wildlife species, attend one or more of the events sponsored by PRLC and other community organizations in our four-part series, beginning April 22, Birds & Bees: Wildlife Needs. Please also see what our neighbors are up to as we work together to certify the town as a National Wildlife Community Habitat.
