A decrease in the marsh willow herb population in an area is likely to be caused by environmental changes such as increased water salinity levels, habitat destruction due to human activities, or competition from invasive species that outcompete marsh willow herb for resources. These changes can disrupt the plant's growth, reproduction, and ability to thrive in its habitat.


Which factor will most likely reduce the carrying of a squirrel population in a forest?
