Population Ecology of Moose in Vermont

Moose in Vermont

Duration

August 2017 - June 2020

Narrative

Concern has risen in Vermont and neighboring states over the past decade regarding high mortality and low recruitment rates of resident moose populations, causing population declines. High winter tick (Dermacentor albipictus) infestations are considered to be a major cause of these trends.

The Vermont Fish and Wildlife Department utilizes population models to estimate regional moose numbers and determine appropriate management actions. Model inputs such as age structure, sex ratio, and mortality and recruitment rates are inputs to this model. Management of Vermont’s moose would benefit greatly from more precise estimates of these rates.

This proposal is to investigate rates of moose mortality, productivity, and recruitment of moose populations over a three-year period in Wildlife Management Units E1 and E2, which collectively constitute moose management region “E”. This region contains 632 square miles of moose habitat, and hosts the highest moose densities (up to 1.75 moose/sq. mi), highest winter tick loads, and low deer densities.

This project is a collaboration between the Vermont Cooperative Fish and Wildlife Research Unit, the University of Vermont, and the Vermont Fish and Wildlife Department. It builds on work done in the neighboring states of New Hampshire, Maine, and New York. The study will contribute to a broader understanding of moose population trends in the Northeast region.
