Biodiversity Conservation and Site Plan Review Biodiversity conservation principles Threats to biodiversity Location of development Reviewing site plans Lunch Reviewing site plans (continued) LEED and biodiversity conservation Examples of effective programs

General Biodiversity Assessment published materials organizations (e.g., MCA, Hudsonia) New York Natural Heritage Program Hudson River Estuary Program s Biodiversity Outreach Program Map resources topographic map soil survey orthophotos stereophotos

General Biodiversity Assessment Topo maps can indicate: intermittent streams floodplains springs & seeps steep slopes potential wet areas many other habitat features

General Biodiversity Assessment perennial & intermittent streams knoll & basin terrain (potential for IWPs)

General Biodiversity Assessment potential areas for riparian wetlands

General Biodiversity Assessment topographic signatures for locating habitats shown on right: steep slopes potential wet areas seepage slope depression intermittent stream

General Biodiversity Assessment soil maps & surveys

General Biodiversity Assessment Soil properties useful for predicting habitats: reaction (ph) drainage class texture depth to bedrock slope

Rare Species Information For most sites, comprehensive field surveys have not been conducted; the enclosed reports only include records from our database. We cannot provide a definitive statement on the presence or absence of all rare or state listed species or significant natural communities within your study area.

Habitat Assessment Qualifications

Priority Habitats & Conservation Zones - Rare or important habitats - Choose focal species (or group) - Use that species requirements to designate Conservation Zone Intermittent woodland pool Pool-breeding amphibians Surrounding forest needed for survival (from scientific literature): 750 ft Conservation Zone: 750-foot radius from each pool

Conservation Zones Pool-breeding amphibians Intermittent woodland pool Surrounding forest needed for survival (from scientific literature): 750 ft Conservation Zone: 750-foot radius from each pool

750 ft (230 m) IWP

Conservation Zones Pool-breeding amphibians Surrounding forest needed for survival (from scientific literature): 750 ft Conservation Zone: 750-foot radius from each pool

Blanding s turtle habitats Associated Wetland Habitats: Vernal (woodland) pools, flooded swamps, beaver ponds, other flooded wetlands Drought Refuge: Spring-fed natural or artificial ponds, or deep pools in wetlands Estivation Habitat: Wetland sediments, upland woods under logs or in shrub thickets, stream pools

Fen Conservation Zone Protect wetland footprint and 300-ft wide buffer from physical disturbance of soils or vegetation, and from applications of pesticides or fertilizers. In 2500-ft conservation zone: -- Avoid construction of new roads or driveways, wherever possible. -- Prevent alteration of groundwater or surface water flows. -- Prevent contamination of groundwater or surface water.
