- Make up a large percentage
- f stream miles
- Cumulatively provide more
habitat than large rivers
- Support species not found
in larger streams and rivers
- High productivity
- Provide important
spawning & nursery habitat for fish

SLIDE 14 North Atlantic Aquatic Connectivity Collaborative (NAACC): Objectives
- Reconnect streams & rivers to support healthier
populations of fish & wildlife
- Proactively identify and prioritize sites for stream
crossing upgrades/replacements
- Facilitate communication and information sharing
among partners

- Original cores meant to be reproducible across NYS
- Used national and statewide data sets including the
NLCD, a USDS nationally available 30 meter land cover data set
- In 2017, a 1 meter landcover data set was
developed for UC, and UC contracted with Green Infrastructure Center, inc. to rebuild the cores layer based on this data
