DESCRIPTION:What is Long Island’s environmental heritage? What did it look like before the Dutch arrive? What habitats were lost over the course of the centuries as Long Island was “developed’? What can be revitalized for future generations? \nOn April 16th at 7pm\, Marshall Brown\, President and Co-Founder of the Long Island Conservancy\, will be talking about the history and future of Long Island’s ecosystems at the Cold Spring Harbor Library\, sponsored by The Dartmouth Club of Long Island. \nIf the ultimate goal is to create a sustainable Long Island – how our understanding of local ecology\, and building upon work done decades ago here on Long Island\, can lead us to that goal. Learn why it is so important to plant native plants and remove invasive ones. \nIn conjunction with Spadefoot Design and Construction\, the Long Island Conservancy has been active in invasive plant removal\, and in the planting of natives. \nJoin us at the Cold Spring Harbor Library\, located at 95 Harbor Road in Cold Spring Harbor\, on Thursday\, April 16th at 7pm.

SUNDAY\, HOWEVER….] \nTrees work 24X7X365 to filter and oxygenate our air\, and filter our groundwater with their roots.  They feed countless species.  Arbor Day After asks\, “How do I act every day so that we will have our trees at all?” \nThe trees at Meadow Croft\, aka “The Roosevelt Estate“\, are under grave threat\, like so many others on Long Island.  They are being choked out by a host of invasive vines as you can see in these photographs. \n\n \n \n \n \n Clear Vines Out By Carriage House\n \n \n \n \n \n Weed Native Plant Garden (New Fencing Coming via a Scout Project)\n \n \n \n \n \n Lots of Vines Covering Farm Implements \n \n \n \n \n \n Tangle of Invasive Vines\n \n \n \n \n \n Forest Floor Being Choked Out\n \n \n \n \n \n More Invasive Overgrowth\n \n \n \n \n \n The Understory Has Been Mostly Taken Over\n \n \n \n \n \n Time To Clear Some Brush\n \n \n \n \n \n We Will Be Expanding The American Chestnut Grove\n \n \n \n \n \n Lots of English Ivy To Take Out\n \n \n \n \n \n All These Trees Will Die …Unless!\n \n \n\nThere is about every noxious invasive plant here:  Mugwort\, Oriental Bittersweet\, English Ivy\, Honeysuckle\, Multiflora Rose\, Wisteria\, Tree of Heaven\, and maybe Japanese Knotweed (but we hope not!). \nBring gloves and lopers.  Wear a good pair of boots and a pair of pants that will protect from thorns.  We can make great strides in saving this forest\, but it will take a small army.   Let’s see what we can do.  We have of course been there before several times to help out.  Last Veteran’s Day\, for instance\, when we had 50 volunteers. \nMeadow Croft is located on Brown’s River between Bayport and Sayville\, at 299 Middle Road\, Sayville on the north side\, as you turn onto a long dirt road with water on either side.  We will be busy removing vines\, weeding the native plant garden\, and planting American Chestnut saplings between 10-1 PM Sunday\, April 27th. \nHere is some more information about last years event at Meadow Croft and our work there\, work you will be continuing this year.  Please indicate using the contact form below that you will be seeking volunteer hours. \n\n← Back Thank you for your response. ✨\n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n\n\n\nName(required)\n\n \n \n \n \n \n \n \n \n \n \n \n \n\n\nEmail(required)\n\n \n \n \n \n \n \n \n \n \n \n \n \n\n\nWebsite\n\n \n \n \n \n \n \n \n \n \n \n \n \n\n\nMessage\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n\n \n \n \n Submit \n \n \n \nΔ URL:https://longislandconservancy.org/event/arbor-day-after-saturday-april-26/ LOCATION:Meadow Croft\, 299 Middle Road\, Sayville\, NY\, 11782\, United States CATEGORIES:American Chestnut,Invasive Removal,Meadow Croft ATTACH;FMTTYPE=image/jpeg:https://longislandconservancy.org/wp-content/uploads/2023/09/Meadow-Croft.jpeg ORGANIZER;CN="The Long Island Conservancy":MAILTO:info@longislandconservancy.org END:VEVENT BEGIN:VEVENT DTSTART;TZID=UTC:20241111T100000 DTEND;TZID=UTC:20241111T130000 DTSTAMP:20260519T020414 CREATED:20241024T175616Z LAST-MODIFIED:20241024T181610Z UID:4500-1731319200-1731330000@longislandconservancy.org SUMMARY:Volunteer Day At Meadow Croft: Caring For Our Native Plants DESCRIPTION:On Monday\, November 11th from 10-1\, The Long Island Conservancy will be hosting a volunteer day at Meadow Croft.  Over the past several years\, The Long Island Conservancy has been reintroducing native plants at this iconic former estate of John Roosevelt while also removing invasive plants. \nMeadow Croft\nWe’ve planted Red Maples along the edge of the meadow\, established a native wildflower garden\, and planted American Chestnut saplings as part of our breeding program.  Native plants are crucial for our native wildlife. \nRed Maples — Crucial Plants\nNative Wildflower Garden Freshly Planted With Native Plants\nA Chestnut Sapling Ready To Plant\nAs winter approaches\, we need to prepare.
