Candidate Conservation Agreements with Insurance (CCAAs) are voluntary agreements between non-federal landowners and USFWS or NMFS. CCAAs provide insurance and allow a specific allocation of incidental costs by the landowner.  Like SHAS, Applicant Conservation Agreements (CSAs) are voluntary agreements between private or public parties (including landowners, public, local and federal authorities) and USFWS or NMFS. CCMs aim to protect declining and threatened candidate species if no action is taken to protect their habitat. CCMs encourage landowners to create, improve or preserve habitat for these species on their land. CCMs do not provide insurance to landowners or allow random registrations.  In the 1990s, Congress considered the adoption of restrictions by creating additional agreements to support species recovery. Safe Harbor agreements and candidate retention agreements put in place by the USFWS and NMFS are incentive and voluntary. Due to their greater flexibility for property owners, these agreements are expected to become increasingly popular.  Like HCPs, Safe Harbor Agreements (SHA) are voluntary agreements between non-federal landowners and USFWS or NMFS. Encourage landowners to create, improve or preserve habitat for threatened or threatened species on their land. Before the agreement, landowners and agencies set basic conditions for the habitat to be able to support the species. The Agency assures landowners and guarantees that, when the conditions of the SHA are met, landowners will not be subject to additional requirements than previously agreed. Accidental takeover by the landowner is allowed as long as the species does not underestimate the agreed basic conditions. Landowners are not tied to ASAs indefinitely and can either renew contracts or let them expire. This allows landowners to freely manage their property, including development, as long as they meet the starting conditions. By 2009, USFWS had completed more than 70 SHAs.  Dedicated teams that manage the HCP contract process end-to-end, from ongoing management to transparency reporting.
When applying for an authorisation authorising the accidental disposal of a listed species, the applicant must determine the extent of the potential admission. To do this, it is necessary to define the methods of calculating ancillary costs. First, it is necessary to determine the number of individuals of each species or the number of hectares of a given habitat that are within the geographical boundaries of the HCP zone. Subsequently, random admission can be calculated on the basis of the number of animals that can be expected to be "killed, injured or harassed" based on the proposed measure/project. . . .
