The whitebark pine tree grows in high elevation ecosystems

Last updated: 4/14/2023

The whitebark pine tree grows in high elevation ecosystems in the northwestern area of the United States Its population has been limited due to the human introduction of a fungal disease known as white pine blister rust to western North America in the early 1900s In some populations of whitebark pine there is relatively little natural resistance to white pine blister rust Based on this information what would be the best long term solution to mitigate the adverse impacts of the fungal disease on whitebark pine trees OA collect and grow seeds of whitebark pine trees that all are identical in genetic makeup and resistant to white pine blister rust OB introduce into the affected region a non native species of plant that is more attractive to white pine blister rust OC collect and grow genetically diverse seedlings of white pinebark pine trees that all have resistance to white pine blister rust OD introduce into the affected region a native organism that is likely to compete for resources with the white pine blister rust
