Ecological Niche Modeling As a Tool for Conservation Planning: Suitable Habitat for Hypericum sinaicum in South Sinai, Egypt
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 6
Abstract
Prediction and mapping of potential suitable habitat for threatened and endangered species is critical for monitoring and restoration of their declining native populations in their natural habitat, artificial introductions, or selecting conservation sites, and conservation and management of their native habitat. We used technique called maximum entropy distribution modeling or Maxent for predicting potential suitable habitat for Hypericum sinaicum, a threatened and endangered species in Saint Katherine Protectorate (SKP), South Sinai, Egypt, using small number of occurrence records. Our objectives were to: (1) predict suitable habitat distribution for threatened herb H. sinaicum using a small number of occurrence records to inform conservation planning in Saint Katherine Protectorate; and (2) identify the environmental factors associated with H. sinaicum habitat distribution. Results showed that the environmental variable with highest gain when used in isolation is bio9 (Mean Temperature of Driest Quarter). The approach presented here appears to be quite promising in predicting suitable habitat for threatened and endangered species with small sample records and can be an effective tool for biodiversity conservation planning, monitoring and management.
