Green Pitcher Plant (Sarracenia oreophila) Recovery Plan

摘要

Current Status: Sarracenia oreophila is listed as an endangered species. There are 25 natural populations known to be extant, including 32 in northeast Alabama, 1 in the northeast Georgia, and 2 in southwest North Carolina. An historical record exists for Tennessee. The majority of the populations occur on private lands and are small in number and the amount of area occupied. Habitat Requirements and Limiting Factors: Habitat for Sarracenia oreophila faries somewhat with some populations located in moist upland areas and other along boggy, and sandy stream edges. Soils of the sites are generally acidic and derived from sandstones or shales. Hydrological conditions (and periodic fire in upland sites) are important in the maintennace of suitable habitat for this species. Several populations have been lost and others have suffered declines in association with agricultural conversion, increased rural residential development, encroachment by woody plants due ot hydrological alterations and fire suppression, and commerical and amateur collecting. Recovery Objective: Delisting. Recovery Criteria: This species will be considered for delisting when a minimum of 18 viable populations, representing the diversity of habitats and the geographic range of the species, are protected and manage as ncessary to ensure their continued existence. Colonies should also include the wide spectrum of current genetic variation found in the species. of the 18 populations, at least three colonies should be located within each of the follwoing four geographic area: Coosa valley, Lookout Mountain, Sand Mountain (East), Sand Mountain(West), and Lake Chatuge. Viability of populations sould be confirmed for at least a 20 year period through monitoring. Actions Needed: 1. Survey for additional populations. 2. Protect, manage, and monitor populations. 3. Gather additional baseline and hydrological data. 4. Study pollination biology. 4. Conduct genetic analysis of populations. 6. Monitor transplant and reestablishment experiments. 7. Preserve genetic stock. 8. Continue public education efforts.
