Current Research

As a Natural Resources Specialist at the Northern Research Station (NRS) I prepare reports on invasive plant species. These reports vary from state to regional assessments and are designed to inform managers and concerned citizens about the status of the invasive plant species monitored in this region. With the NRS data I further investigate regional trends, patterns, and changes including site level characteristics that may impact the presence of invasive plants.

Research Interests

My interests are to explore various invasive plant topics and to further investigate what factors are driving their presence and abundance.

National Research Highlights

Map of invasives across the Northern U.S.  Cassandra Kurtz, USDA Forest Service

Examining the Spread of Invasive Species Using Data from the Forest Inventory and Analysis Program

Year: 2014

Invasive plant species threaten the integrity of our ecosystems and cost billions of dollars in damages and removal costs annually. Forest Service scientists have prepared a series of research notes, each featuring an invasive plant species that is monitored on Forest Inventory and Analysis (FIA) plots across 24 states in the northeastern and Midwestern United States.
