OlyEcosystems approach to restoration and habitat conservation is based on scientific studies and data. We work closely with local scientists, consult college and university experts, and incorporate the latest research to inform our activities. In addition, several Board Members are Ph.D.-level scientists.
Science helps OlyEcosystems to:
maintain habitat for existing wildlife through conservation.
increase habitat quality of currently undeveloped yet degraded woodlands.
encourage responsible urban growth that accounts for both the intrinsic value of wildlife and the value of green space to the physical, social, and psychological well-being of our community.
connect science and data to inform and shape local, state, and federal policy.
