Those who visit the pine-barrens of New Jersey know what a pleasure it is to ramble along the narrow wooded-ppaths among the pine trees ; old paths that after once being made continue for many years, and may seldom entertain a pedestrian. Along these paths and by the side of the sandy roads, any time during late summer arrd until frost, one may hear a faint, lisping little song from a grasshopper corning from the pines, often from their topmost branches. It is an easy matter to climb the pitch-pine, which is usually arranged admirably for the purpose, and the grasshopper is also friendly to investigation, and commonly continues to stridulate.

The effects of simulated acid rain solutions on growth of pitch pine (Pinusrigida Mill.) seedlings in undisturbed soil cores from the New Jersey Pine Barrens were examined. Solutions of pH 5.6, 4.0, and 3.0 (SO42−–Cl−–NO3−, 4:2:1), totaling 1.4 times annual ambient precipitation, were applied directly to soil cores from the A horizon during a 1-year period. By varying photoperiod and diurnal temperature, two growing "seasons" with an intervening dormant period were simulated. Soil chemistry, soil leachate chemistry, seedling nutrition, and seedling growth were monitored. Seedling dry weight was significantly greater at pH 3.0 than at the less acid treatments. Foliar nutrient contents indicated that growth stimulation at pH 3.0 probably resulted because of increased availability of nitrogen and input of nutrient cations from acid-induced weathering of soil minerals. There were sharp increases in Ca and Mg leaching when the pH of the irrigating solution was lowered, but solution acidity had little effect on depletion of K. Declines in nutrient leaching during the experiment indicated that weatherable cations were becoming depleted. Although Al mobility was greatly accelerated by an increase in acid inputs, Al toxicity symptoms were not observed.

The “Pine Barrens” are a UNESCO-designated biosphere reserve encompassing about 1.1 million acres in southern New Jersey. A state agency, the New Jersey Pinelands Commission, in conjunction with county and local governments, works to implement land management and environmental protection goals via a comprehensive management plan. The pinelands development credit (PDC) program is one tool aimed specifically at land preservation outcomes. The PDC program is a regional “transfer of development rights” market allowing landowners to sell their rights to further develop their property and enter their land into permanent protected status. Since the program’s inception in 1982, over 55,000 acres of sensitive and rare ecosystem have been protected; the more than 1,200 transactions account for US$63 M of economic value. The PDC program is a clear illustration of the role that financial instruments and market mechanisms can play in achieving environmental protection outcomes. This case study offers an overview of the pinelands area, PDC program, and the transfer of development rights concept before examining the PDC program and its outcomes in greater detail. While the program has been hailed as a success, it will face challenges in the coming years, including a relatively inefficient process for converting PDCs into protected lands and the question of how the program can evolve once eligible lands become more scarce.

Firebrands are an important agent of wildfire spread and structure fire ignitions at the wildland urban interface. Bark flake morphology has been highlighted as an important, yet poorly characterized factor in firebrand generation, transport, deposition, and ignition of unburned material. Using pine species where bark flakes are the documented source of embers, we conducted experiments to investigate how bark structure changes in response to diurnal drying. Over a 3-day period in a longleaf pine (Pinus palustris Mill.) stand in Florida, we recorded changes in temperature, moisture content and structure of bark across different facing aspects of mature pine trees to examine the effects of varying solar exposure on bark moisture. We further compared results to bark drying in a pitch pine (Pinus rigida Mill.) plantation in New Jersey. Under all conditions, bark peeled and lifted away from the tree trunk over the study periods. Tree bole aspect and the time of day interacted to significantly affect bark peeling. General temperature increases and moisture content decreases were significantly different between east and west aspects in pitch pine, and with time of day and aspect in longleaf pine. These results illustrate that bark moisture and flakiness is highly dynamic on short time scales, driven largely by solar exposure. These diurnal changes likely influence the probability of firebrand production during fire events via controls on moisture (ignition) and peeling (lofting).
