First find the total number of cranberries harvested by humans: 60000 cranberries * 40% = 24000. Then subtract the number of cranberries taken by the humans and elk to find the number remaining: 60000 cranberries - 24000 cranberries - 20000 cranberries = 16000 cranberries.
Thus, the answer is 16000.
