Plano nature preserves Oak Point Park and Arbor Hills have retained their status as Certified Audubon Cooperative Sanctuaries.

Certification is done through the Audubon Cooperative Sanctuary Program, an organization that encourages the protection of land, water, wildlife and natural resources, according to a recent news release from the city of Plano.

Both nature preserves had to demonstrate an immense level of environmental quality to retain this certification, according to the release. Some of the certification categories include environmental planning, wildlife and habitat management, outreach and education, and resource management, per the release.

According to the city, projects at the nature preserves focus on connecting people to wildlife, enhancing habitats and preserving natural resources.

“Plano Parks & Recreation strives for equilibrium within the city’s nature preserves and the intertwined public park space,” Park Services Manager David Angeles said in the release. “A balance between stewardship and recreational park amenities is important to maximizing the green space for residents, wildlife, and environment.”

Arbor Hills and Oak Point Park became Certified Audubon Cooperative Sanctuaries in 2012 and 2015, respectively.
