Habitat alteration, most frequently caused by channelization, irrigation, and reservoir construction, has eliminated many sandbars used for nesting. Certain recreational activities along riverways also disrupt nesting.
The State's least tern population successfully nested during the past 2 years due to intervention to eliminate human disturbance, discourage predation, and reduce encroaching vegetation.
Determining the species' distribution and population trends, as well as its habitat requirements and status, are important. Of equal importance is the protection of least tern populations during the breeding season. There is also need for a public education program on the species and what can be done to aid its recovery.Section 6 Funding and Activities:
The Indiana Department of Natural Resources received $7,200 in FY 1991 and $5,400 in FY 1992 to survey and manage the State's least tern population. In FY 1991, program money was used to survey and monitor existing colonies; in FY 1992, the tern colony received protection from human disturbance.Partnerships
Indiana Department of Natural Resources: This State agency controls vegetation, maintains nesting substrate, and protects least tern nurseries from human disturbance. Surveying and monitoring of tern colonies will be completed in December 1992. In 1990, a gate was installed and signs posted to protect terns during the nesting season.PSI Energy: This company voluntarily controls vegetation on, and access to, the tern colony nesting on its property.
Recovery Plan Status:
Plan approved 9/19/90.
