NH Fish and Game classifies pesticides as a threat not only to wildlife, but also to their habitats and to our entire ecosystem.
From the NH State Wildlife Action Plan (SWAP):
Pesticides are a significant conservation concern. The SWAP classifies them as pollution under the threat category “Agricultural and forestry effluents / Herbicides & pesticides.” The SWAP documents that pesticide use contributes to direct wildlife mortality, particularly among insects and other invertebrates (including impacts from neonicotinoids), and to habitat degradation through runoff, especially in streams, wetlands, and other aquatic systems. The plan's threat summaries describe herbicides and pesticides as among the most commonly identified threats to New Hampshire’s Species of Greatest Conservation Need, underscoring pesticide pollution as a statewide issue affecting both species and ecosystems.
State Wildlife Action Plans are science-based conservation plans required for states to receive federal wildlife funding. Each state submits a plan that identifies Species of Greatest Conservation Need, the threats they face, and actions to prevent species from becoming endangered. Every ten years, U.S. states submit their SWAP to the US Fish and Wildlife Service (USFWS) for approval.
NH Fish and Game submitted its SWAP for 2025-2035 in September, and it was approved by USFWS in December, 2025. Read it here
