Which of the following factors led to the decline of the American chestnut tree population?
A
A fungal blight caused by Cryphonectria parasitica
B
Increased competition from invasive plant species
C
Overharvesting for timber and nuts
D
Climate change leading to unsuitable growing conditions
Verified step by step guidance1
Identify the main cause of the decline of the American chestnut tree population by examining historical and ecological data.
Understand the role of Cryphonectria parasitica, a fungal pathogen, in causing chestnut blight, which led to widespread tree mortality.
Consider the impact of increased competition from invasive plant species, which may have further stressed the American chestnut populations.
Evaluate the effects of overharvesting for timber and nuts, which could have reduced the number of mature trees capable of reproduction.
Analyze how climate change might have altered the growing conditions, making them less suitable for the American chestnut tree, thereby contributing to its decline.
