House committee hears how Vermont Conservation Design maps priorities for species and landscape connectivity

On April 3 the Vermont House Energy and Digital Infrastructure Committee heard a presentation from the Vermont Department of Fish and Wildlife on Vermont Conservation Design, a scientific framework the department developed to identify lands and waters most important for maintaining ecological function into the future. Andrea Short Sleep, interim commissioner, and Robert Zaino, natural community ecologist, described how the design layers landscape features, natural communities and habitat targets to guide conservation planning and project review.

The committee was told the design is a planning tool, not a regulatory prescription, and that it has been used to inform reviews under Act 250 and Section 248 and to guide town planning and state land conservation work. “Vermont Conservation Design…is a scientific framework for conserving Vermont’s ecological function into the future,” Andrea Short Sleep said.

Department staff framed the design around three simple goals: keep landscapes intact, connected and diverse. Robert Zaino said conserving larger landscape elements—such as intact forest blocks and riparian corridors—creates efficient proxies that protect many species and the processes they need to survive and adapt. “Boiling that down to three words, it’s about maintaining a landscape that’s intact, connected and diverse,” Zaino said.

Zaino explained the design’s components: mapped forest or habitat blocks (about 4,000 blocks larger than 20 acres were identified using LIDAR), prioritized interior forest areas, connectivity corridors for species movement, and a suite of natural communities (97 community types were referenced). The department showed updated, high‑resolution forest block mapping produced with University of Vermont spatial data and said those maps reveal narrow “stringy” connections and specific road crossing points that may matter for wildlife movement.

The presentation listed specific conservation targets the design seeks to maintain: representation of natural community types (for example, alpine meadows and calcium‑rich forests that host species such as the West Virginia white butterfly), targets for young and old forest structure, grasslands for nesting birds, and riparian and aquatic habitats. Zaino said preserving that mix increases confidence that both common and many rare species will have habitats now and as climates change; he also noted some species—such as a tiny softshell turtle that requires intense hands‑on nest protection—fall outside what the design alone will secure and will require species‑specific intervention.

Committee members asked about how the design intersects with landowner rights and local planning. Zaino and Short Sleep emphasized the tool informs options rather than dictating landowner decisions: forest management, timber harvest and private stewardship are compatible with many of the design’s forest‑block guidelines. The department noted the design is already used to prioritize land acquisition, inform management of state lands, provide technical assistance to towns and landowners, and to inform Act 250 and Section 248 review where the agency considers whether a project creates an undue adverse effect on the natural environment.

Zaino described a few summary figures provided during testimony: best estimates that Vermont may host up to 40,000 species; most Vermont forest is roughly 100 years old (creating a gap in young and old forest structure); roughly 30% (he said “30ish percent”) of the places the design identifies as important are currently protected (he cited a higher share for forest blocks—near 40%—and lower protection for riparian areas); and that just under about 80% of Vermont is currently forested or natural land.

Short Sleep and Zaino stressed that implementing the design fully would be a major change if done only by large‑scale protection, and that a full toolbox—land acquisition, incentives such as the use‑value appraisal program, landowner stewardship, targeting of state funds and technical assistance—will be needed. Zaino said the design gives planners and communities a way to see how individual conservation projects fit into a larger ecological picture and to help identify places where development may be less ecologically costly.

The presentation concluded with committee chair remarks that the session provided an overview useful to the bill sponsor; the committee is also considering H.394, which references conservation design in broader energy‑siting discussions.

Ending: The department urged the committee to view the design as an integrative planning tool rather than a binding rule, and said staff would provide more detailed numbers and follow‑up information if the committee requests it.
