About the Program
The Mount Hope Quarry program is run by CRH Americas Materials Inc. Located in Rockaway Township, Morris County, New Jersey, the program site contains a working quarry. Rockaway Township is located approximately 35 miles northwest of New York City and is within the Rockaway River watershed. The quarry site is part of the New Jersey Highlands region, an area noted for its natural resources, and contains wetlands, lake and forested areas with trails. These habitats support a diversity of wildlife, and projects to monitor species such as bats and bald eagles are operated by the team.

Practices and Impacts
  • The project site is close to known bat hibernacula.
  • Monitoring by echolocation has identified several species of bat native to the region at the site. This monitoring is important, as bat populations in the region have been impacted by white-nose syndrome.
  • Data collected by the team is shared with the USFWS. 
  • Breeding populations of bald eagles are classified as endangered in the state of New Jersey.
  • Bald eagles have been observed at the site since 2010, with a resident breeding pair nesting since 2012.
  • Frequent monitoring has followed the pair's behavior, with ten eaglets produced by the pair since observations began.
