A combination of altered fire regimes and pathogens has contributed towards densification and encroachment by shade-tolerant species into areas traditionally dominated by whitebark pine. As such, the CMP Hi5 Working Group technical team suggest canopy cover as a proxy for species encroachment. Stands with tree cover greater than 60% suggest successional species are outcompeting whitebark pine.

As a result of climate change, a warmer and drier climate has led to an increase in wildfire severity. Severe wildfires can cause whitebark pine mortality during all life stages. Conversely, low intensity fires may enhance whitebark pine persistence by removing competing species that are less fire tolerant. However, low intensity fires have been suppressed because of an increase in recreational development and urbanization. Thus, a decline in low intensity fires has reduced whitebark pine persistence by increasing species encroachment while simultaneously, increases in wildfire severity are increasing whitebark pine mortality
