The book describes ecosystem and habitat types across the region, the geologic processes that laid the Pine Barrens' sandy floor and water-saturated underground aquifer, and human impacts from pre-Colonial times to the present. There's detailed explanations for the Pine Plains, the dwarf pine forest on the southern Ocean-Burlington county boundary, and the "fire ecology" that defines the region.
"What I try to do in the book is present the abiotic and the biotic factors about the Pine Barrens," Boyd says. That first set of characteristics starts around 14,000 years ago with the withdrawal of the last Ice Age glacier from northern New Jersey, and the slow warming of what had been a windblown, subarctic desert to the south.
