Mercury is a global pollutant that impacts communities at the local level. The Finger Lakes Mercury Project was initiated in 2015 by the Finger Lakes Institute in collaboration with Finger Lakes Community College, to assess the extent of mercury contamination in Finger Lakes aquatic food webs. Findings will be presented for Canandaigua Lake zooplankton, benthos and fish, stream macroinvertebrates and fish, and placed in the context of trends observed for other Finger Lakes.
Presented by: Roxanne Razavi (PhD, Queen’s University, 2014; ecotoxicology, limnology, environmental toxicology, mercury) Roxanne is an Assistant Professor in SUNY ESF’s Department of Environmental and Forest Biology.
HWA WORKSHOP FOR LANDOWNERS
Tuesday, January 23rd at 6:00 PM
South Bristol Town Hall
CLWA hosted a landowner workshop on the impacts of the Hemlock Woolly Adelgid (HWA), an invasive forest insect that is threatening our region’s hemlock trees.
HWA has been found throughout the Canandaigua Lake watershed and tree mortality typically occurs 6-10 years after infestation. Landowners are encouraged to attend a workshop on Tuesday, January 23rd at 6:00 PM at the South Bristol Town Hall to learn more about the threat, and how to identify and manage HWA on their own property.
The workshop, led by Charlotte Malmborg of the New York State Hemlock Initiative, will feature information on the identification of hemlock trees and HWA, management strategies for landowners, and key information on the history and fate of HWA across the region. The NYS Hemlock Initiative’s new Biocontrol Research Lab on the Cornell Campus will also be discussed. A licensed pesticide applicator will be on hand to answer questions about the various treatment options available to landowners.
Eastern hemlocks occupy a unique position in our Finger Lakes forests. Because they are so shade tolerant, they grow in the shady gullies where other trees can’t. Their cover and root systems help to reduce both erosion and the temperature for the streams running to Canandaigua Lake. Hemlocks are the “cornerstone” of a unique ecological community of plants, such as ferns and mosses, and animals, such as salamanders and brook trout that are increasingly rare in urbanized areas. CLWA is very concerned about the potential loss of hemlocks in the lake’s gullies that could lead to increased erosion and nutrient losses.
VIEWPOINTS SEMINAR SPEAKER SERIES
Phosphorus: Forms, Bioavailability, and Importance
Presented by: Tony Prestigiacomo
Tony is a Research Scientist with the DEC’s Finger Lakes Watershed Hub who’s interests include water quality monitoring, nutrient loading, and the interactions between lakes and streams.
Blue Green Algae Blooms: Is Phosphorous Responsible? Phosphorus is often described as the nutrient that limits primary production in temperate freshwater ecosystems. However, phosphorus exists in multiple forms and not all forms are equally useable by algae and phytoplankton for growth. Understanding common types of phosphorus and their relative availability to primary producers can be important knowledge for management of watersheds and lake water quality.
