Hudson River Ecology

How does the Hudson River ecosystem respond to different types of changes over time? Are these changes permanent, and how will the ecosystem respond? Our curriculum addresses these questions through modules which combine unique and engaging Hudson River data collected by the Cary Institute and other scientists, investigations, readings, and visualizations.

Invasive Species

Nutrients & Energy
Nature of Science

Invasive species pose a serious risk to ecosystem health and stability around the world and locally. Why should we be concerned about invasive species? How do they change local plant and animal communities? How do they change the chemistry of a water body like the Hudson River?   Students will learn how and why invasive species have such large ecosystem impacts and how they have changed the Hudson River. This unit includes a more in-depth investigation of three species: zebra mussels, water chestnut, and common reed.  As students will discover, all of these introduced species have changed the ecosystems around us in potentially positive and negative ways.  The concluding research report provides an opportunity for students to explore other local invasive species.

  • Introduction to Invasive Species

    Students will know why we call some species invasive and be able to discuss several traits that are common among many invasive species and be able to explain the effects of at least one invasive sp

  • Invasive Plant Survey

    Students will investigate whether there are more native or invasive plants and how herbivory affects both types of plants in their schoolyard.   

  • How Does Water Chestnut Impact the Hudson River?

    Students will understand how the invasive water chestnut plant impacts the Hudson River differently from the native water celery plant and be able to explain these impacts based on a series of grap

  • Aquatic Plant Invasion: Simulation

    Students will know the relationship between light and dissolved oxygen and be able to predict what will happen when a plant does not receive enough light.

  • Impacts of Common Reed & its management

    Students will know that removing an invasive plant can have a variety of impacts and be able to explain some of these impacts using evidence.

  • Invasive Species Independent Research Report

    Students will know that aquatic communities change composition based on vegetation types and be able to explain the differences.

  • Invasives and Macroinvertebrates

    Students will know that aquatic communities change composition based on vegetation types and be able to explain the differences.
