2 Objectives Outline Invasive Species Problem What is APIPP? Describe Aquatic Species Spread Prevention Brant Lake Update Management Let s look at some plants!

3 What s the Difference? 1. Native Species Species indigenous to a region at the time of European settlement 2. Non-native Species (Exotic, Introduced, Alien) Accidental or purposeful introduction of a species outside of its historic range 3. Invasive Species (Noxious) Species that rapidly reproduces, displaces native species and causes ecological, economic or societal harm 4. Nuisance Species (Weed) Species that interferes with human activities

4 Benefits of Native Plants Provide food Provide shelter and spawning habitat Produce oxygen Protect shoreline Stabilize sediments Reduce turbidity Transport nutrients Support diversity

5 Characteristics of Invasive Plants Lack predators, parasites, and disease to limit growth Produce many small seeds and reproduce early May reproduce both by seed and vegetative growth Have few special seed germination requirements Generalists capable of colonizing a wide range of sites Monopolize resources such as light and nutrients May produce toxins that suppress the growth of other plants

13 Nonnative Fishes - Historic Conditions Relatively few fish species in interior waters

14 Yellow perch, smallmouth and largemouth basses, the northern pike, the chain pickerel and many other species were then almost endlessly dumped upon the Adirondack uplands.

15 Impacts of non-native fishes Ecosystem altered by top-down cascading effects. Predation and competition cause severe declines in brook trout and round whitefish.

16 1890: are found in nearly all the salmon and trout lakes in the Adirondacks. Now: Seven waters (scarce in most) plus some recent stockings.

22 Our Mission To Protect the Adirondack Region from the Negative Impacts of Non-native Invasive Species

23 APIPP Coordinates Two Projects Terrestrial Invasive Species Project Aquatic Invasive Species Project Purple loosestrife Eurasian watermilfoil Photo by Gordon Keyes

24 APIPP Objectives 1. Prevent new invasions. Increase public awareness and involvement to prevent the spread of invasive plant species. Education 2. Rapidly detect and eradicate infestations. Coordinate regional invasive plant inventory and monitoring program utilizing staff and volunteers. Monitoring 3. Manage established infestations. Facilitate the management, containment, and control of priority invasive plant infestations. Management

25 Partnerships Adirondack Mountain Club Au Sable River Association Boquet River Association Clinton and Essex County Master Gardeners Cornell Cooperative Extension Darrin Fresh Water Institute Federal Highways Administration Franklin County Network of Shoreline Associations Hamilton County Soil and Water Conservation District Lake Champlain Basin Program Lake Champlain Sea Grant Lake George Association Lake George Land Conservancy Paul Smiths College Watershed Stewards Program Residents Committee to Protect the Adirondacks Student Conservation Association SUNY Plattsburgh Adirondack Volunteers!

26 Prevention, Early Detection, and Rapid Response are the Keys to Successful Eradication!

27 Lakes Surveyed and Plant Distribution As of May 2010: Total Number of Waters Infected: 74 Total Number of Volunteers: 392 Total Number of Lakes Surveyed: 243

28 Opportunity Exists Number of Infested Lakes and Weed-Free Lakes in the Adirondack Park, Cumulative # of weed free lakes Cumulative # of Infected Lakes (Prevolunteer surveys) 2002 (Year 1 of volunteer surveys) 2003 (Year 2) 2004 (Year 3) 2005 (Year 4) 2006 (Year 5) 2007 (Year 6) 2008 (Year 7) (Year 8)

44 How are invasive species introduced and spread? Pathways Ballast Nurseries / Ornamentals Aquaria / Water Gardens / Pet Trade School releases Roadways Vehicles / watercraft Canals Clothing / Gear / Equipment Fill, mulch material Disturbance Firewood Wildlife Wind / Waterways Roadway Corridors Ornamentals Disturbed Areas Watercraft

46 Management Techniques Physical Handpulling, cutting, matting Chemical Biological Cultural Revegetation Do Nothing Divers in Upper Saranac Lake

47 Spread Prevention Shoreowner education Signage (boat launch) State Municipal Private Stewards (boat launch) Paid Volunteer Stations (boat wash) Lake George Upper St. Regis Stations (disposal) Buck Pond Lake Flower Lake Placid Surveys Paid Volunteer

49 2009Paradox Lake Milfoil Survey Plan

50 Spread Prevention Continued Avoid boating through invasive plant beds Never release unwanted bait into a waterbody Never move fish from one water to another without the proper permits Check your boat before you float! Clean off your boat / remove vegetation Clean out / disinfect live wells

51 Spread Prevention Protocol Check and remove any visible mud, plants, fish, or organisms from boats, trailers, equpiment, etc. Clean and eliminate water from equipment Dry anything that comes in contact with water Never release plants, fish, or other animals into a waterway unless they came from that waterway.

52 Action Plan for Milfoil Issue Brant Lake, New York

53 Our approach Similar to fighting weeds in regular garden: Identify and locate Surveying Reports from locals Head-A-Bed Remove or kill Hand harvesting and Benthic matting with Volunteers AIM

54 Results of our approach Where are we NOW compared to where we would be if we had taken NO ACTION

55 2009 Maps over time without action

56 2009 Where we were at the end of 2009

57 Tools for YOU to help If you find a bed or Head -A-Bed Call it into 518/ or write to lynchte71@yahoo.com If you are a diver and want to help Sign up on our website and write Luc.aalmans@gmail.com to set up a dive event If you are a volunteer Sign up on our website and help as surface crew or other All info is available on:

58 Action Plan for 2010 Goals All known beds contained No large dense growth anywhere Many old benthic mats removed New beds under control Shallow hand harvesting team self-sufficient Head-a-bed revamped All volunteers committed for next year Agreement on boat launch

59 Help AIM Five or six weeks Hand harvesting in line sweep Our Divers Every Saturday from 10AM till 1PM Cover dense areas, IF ANY, with benthic mats Focus on small localized beds Remove mats You As much and as often as you can

60 Your Help Needed Head-a-bed (Name ) Assisting our divers (All) Refurbishing recovered mats (All) Kayakers / boaters to look for beds (Name ) Milfoil awareness and fundraising (Name ) Shallow water harvesting, 0-3 feet (Name ) Water Keeper / Water Steward (Terry Lynch)

61 Your Help Needed Liaison to Paul Smith College, APPIP, APC, State, etc. (Karen Meltzer) Project Manager (Dave King) Mapping the lake bottom (Harvey Leidy) APA permit process (Doug Paton) Boat launch (Doug Paton) Other methods (Dave King & Irv Freedman) Weevil, Suction, Chemicals, Current permits, etc.
