Section 10 may also allow activities that can unintentionally impact protected species.  A common activity might be construction where these species live. More than half of habitat for listed species is on non-federal property. Under section 10, impacted parties can apply for an incidental take permit (ITP). An application for an ITP requires a Habitat Conservation Plan (HCP). HCPs must minimize and mitigate the impacts of the activity. HCPs can be established to provide protections for both listed and non-listed species. Such non-listed species include species that have been proposed for listing. Hundreds of HCPs have been created. However, the effectiveness of the HCP program remains unknown.
