Quizplus · Accepted Answer

The absence of the plant's pollinator is the most likely biotic factor that could explain why this plant has not successfully reproduced. With the surrounding agricultural land now in place, it is possible that the plant's original pollinator population has declined or disappeared entirely, leaving the plant without a reliable means of reproducing.
