Table 1.

Examples of management actions that were delayed or cancelled at national park units in 2020.

Park	Management action	Consequence
Many parks	Delayed or reduced invasive plant management	Invasive plants had an additional year to grow and reproduce, making future management more difficult
Acadia National Park	Delayed vegetation restoration on Cadillac Mountain until 2021	Further degradation of restoration site and greater expense to maintain restoration plant stock
Gila Cliff Dwellings National Monument	Delayed new trail to reduce damage to archeological sites	Potential damage to archeological sites
Rocky Mountain National Park	Cancelled spring elk counts and moose collaring; limited winter elk counts	Less data to inform wildlife management
Rocky Mountain National Park	Cancelled monitoring and pruning of white pine blister rust (Cronartium ribicola) on limber pine (Pinus flexilis)	Increased damage to limber pines, a species of management concern
Sequoia and Kings Canyon National Parks	Delayed retrofitting of park restrooms to exclude bears	Additional problems with bears damaging restrooms
Tonto National Monument	Delayed post-fire vegetation restoration projects	Potential erosion and damage to plant communities
Yosemite National Park	Cancelled annual songbird banding	Disruption of 30-year annual dataset and reduced ability to detect population shifts associated with climate change
