Sapsucker wells on trees

Sapsuckers are important keystone species in forests. Their creation of sap wells provides food resource access for many other species. Your observations will help in mapping the distribution of trees with sap wells created by these important woodpeckers (trees WITHOUT sap wells are also included). This project is part of the EREN Flexible Learning Module entitled Sapsucker Tree Use Across Diverse Landscapes created by Dr. Sandra Cooke (Greensboro College). menos ↑
