National Grid Karner Blue Butterfly Habitat SurveyAugust 9, 2017
Chazen has conducted surveys for the federally and NYS endangered Karner blue butterfly (Lycaeides Melissa samuelis) and state threated frosted elfin (Callophrys irus) as well as blue lupine (Lupinus perennis), the host plant for butterfly larvae. Surveys were conducted along approximately 161 miles of utility rights-of-way near Albany in eastern New York, the Tonawanda region of western New York, and the Rome Sand Plains of central New York. Surveys consisted of mapping populations of blue lupine and butterflies with Trimble GPS units. Lupine stands were surveyed using GPS/GIS receivers which were then mapped onto aerial photographs with GIS. All work was documented and peer reviewed by the US Fish and Wildlife Service (USFWS) and New York State Department of Environmental Conservation (NYSDEC).
Chazen was also retained to complete the first Habitat Conservation Plan in the northeaster United States under Section 10 of the federal Endangered Species Act for Karner Blue Butterflies.
Chazen has subsequently been hired over multiple years to re-survey habitats and butterfly populations in support of the approved Habitat Conservation Plan.
