Aquatic Plant Communities of the Acton-Wakefield Watershed Area

Amy Smagula – Limnologist/Exotic Species Program Coordinator, NHDES

Abstract:

Explore the vast array of common aquatic plants native to the lakes and ponds within the watersheds of Acton and Wakefield.  We will discuss aquatic plant community structure, plant identification, ecology, and the functional values of these aquatic plants.  The presentation will also touch on non-native invasive aquatic plants already in the area, as well as those that could be a future threat.  We will also discuss control options for aquatic plants, including permit requirements related to these control actions.

Cyanobacteria: Biology, Ecology, and New Sampling Methods

Jim Haney – Professor Emeritus, Center for Freshwater Biology and Ecotoxicology in the University of New Hampshire Department of Biological Sciences

Abstract:

One of the most widespread problems in lakes is the increase in the toxin-producing cyanobacteria.  Although the abundance of cyanobacteria is generally associated with increases in nutrients such as phosphorus and nitrogen, we are now learning that the risks associated with cyanobacteria can be related to lake-specific features and to toxic picocyanobacteria not seen in surface blooms.  These smallest of the cyanobacteria can be transmitted in the air to humans and wildlife.  The Ecotoxicology Laboratory at the University of New Hampshire has incorporated our current understanding of lake cyanobacteria into a 3-step citizen-based cyanobacteria monitoring program that addresses many practical concerns such as:

  1. What are cyanobacteria and are they in my lake?
    2. Are all cyanobacteria toxic and what health risks do these toxins pose?
    3. When is it safe to recreate in the lake or to allow pets to drink the water?
    4. Can blooms be predicted before they occur?
    5. Is it possible to citizens to estimate whether a bloom is like to be toxic?

Jim Haney is a Professor Emeritus in the Department of Biological Sciences at the University of New Hampshire.  He is Director of the UNH Center for Freshwater Biology and co-founder of the New Hampshire Lakes Lay Monitoring Program.  Dr. Haney’s professional fields include Lake Ecology, Stream Ecology and Ecotoxicology.   His current research focus is on the transfer of cyanobacteria toxins within the lake food webs and their impact on humans and wildlife.  Other research projects include 1) toxic aerosols as risk factors from lakes with toxigenic cyanobacteria 2) use of cyanobacteria pigments as a citizen monitoring method to predict cyanobacteria blooms and lake toxicity.  He and his students have conducted collaborative research with Dartmouth-Hitchcock ALS Clinic to evaluate toxic aerosols as possible links between cyanotoxins and neurological disorders such as amyotrophic lateral sclerosis (ALS).  He is also a member of the USP EPA Region 1 Cyanobacteria Monitoring Collaborative (cyanos.org). 

Effects of Climate Change on New Hampshire’s Birds

Dr. Pamela Hunt – Senior Biologist for Avian Conservation, NH Audubon

Abstract: 

We are already seeing some of the effects of climate change in New Hampshire, with a trend toward warmer winters, more extreme weather, and drier summers. How will our birds – both breeding and migrant – be affected by these changes as they manifest over the next several decades? In most cases we don’t know the answers, but there is often enough information to allow some informed speculation. In this talk, we explore subjects as diverse as range shifts, declining food supplies, and changes in migration patterns as they apply to the birds of New Hampshire. What will birders in the 22nd Century encounter in the Granite States forests, fields, and wetlands? Learn a little about the possibilities.

Pam Hunt has been interested in birds since the tender age of 12, when an uncle took her to Brigantine National Wildlife Refuge in NJ. She went on to earn a B.S. in biology from Cornell University, M.A. in zoology from the University of Montana, and a Ph.D. from Dartmouth College in 1995. Pam came to NH Audubon in 2000 after five years as adjunct faculty at Colby-Sawyer College in New London. In her current position as Avian Conservation Biologist, she works closely with NH Fish and Game to coordinate and prioritize bird research and monitoring in the state, and also authored NH’s “State of the Birds” report. Specific areas of interest include habitat use by early successional birds (particularly whip-poor-wills), conservation of aerial insectivores (e.g., swifts and swallows), and the effects of events outside the breeding season on long-distance migrants. Pam also coordinated the “NH Dragonfly Survey,” a five-year project that mapped distributions of these insects throughout the state, and remains active in the dragonfly field.

Cyanobacteria and the Lakes

Amanda McQuaid – Harmful Algal and Cyanobacterial Bloom Program, NHDES

Abstract:

Cyanobacteria blooms are a growing public health concern as elevated cell concentrations can present toxic conditions. NHDES issues recreational advisories when bloom conditions are confirmed. “Cyanobacteria Advisories” are issued when samples are collected and identified, with cell concentrations exceeding the state threshold of 70,000 cells/ml. “Cyanobacteria Alerts” are also shared when photos and reports have been submitted, but a sample has not yet been collected. Alerts and advisories help notify the community, advising to be on the lookout for cyanobacteria accumulations along shorelines and throughout the lake. The highest number of advisories have been issued in recent years, with 34 in 2018, 35 in 2019, and 23 advisories (plus 35 alerts) in 2020. Potentially toxic taxa have included Anabaena (Dolichospermum), Microcystis, and Oscillatoria (Planktothrix). However, there is a wide range of types of cyanobacteria identified in NH lakes. In this talk, we will discuss the importance of monitoring cyanobacteria and their toxins.

Common Loon Conservation in New Hampshire

Caroline Hughes – Staff Biologist, Loon Preservation Committee

Abstract :

For many, the haunting call of the loon is a quintessential part of the New Hampshire lake experience. Often seen as a symbol of the northern wilderness, loons are a beloved fixture on our lakes, and many lake-goers enjoy watching them as they raise their young. However, the breeding season can be a vulnerable time for loons—they face many threats, both natural and human-caused, while on our lakes. This presentation will focus on the biology, life history, and challenges of breeding loons as well as the work that LPC has been performing since 1975 to help recover New Hampshire’s threatened loon population.

Bird Migration: Fun Facts & Shameless Speculations

Pam Hunt – Avian Conservation Biologist, NH Audubon

Abstract:

Why do birds migrate? How do they know where they’re going? The phenomenon of bird migration has fascinated people for millennia, and in this program the answers are finally revealed! Pam Hunt will provide an overview of the nuts and bolts of bird migration, including how scientists study it. We’ll also discuss examples of migration routes of some familiar (and unfamiliar) species and touch on the conservation issues facing migratory birds.
