In the late 1800s, a vertical shaft was constructed at Bracken Cave to extract the guano. Unskilled laborers worked inside, shoveling the harvest into buckets, which were then hoisted up through the shaft. Although the process has been modernized, the guano is still extracted today through the same 100-year-old shaft.
How is guano harvested?
Guano is harvested much the same way it was hundreds of years ago, with a squadron of workers manually scraping, sifting and bagging it. The government, through a division of the Agriculture and Irrigation Ministry, selects about 400 men each year to work eight months as harvesters.
