This issue represents the final one in volume 76 of Journal of Wildlife Management. As this one is pretty much in the books, one cannot help but wonder what the future holds for the journal. Lenny Brennan is putting together a piece for Wildlife Society Bulletin to examine how The Wildlife Society publications have changed through time. He solicited input from past and present Editor-In-Chiefs, including me. In my contribution, I contrasted topics of papers published in volume 31 of the journal (1967) with those published in volume 75 (2011). Over this span of nearly 35 years, papers...

Bond, Monica L.; Siegel, Rodney B.; Hutto, Richard L.; Saab, Victoria A.; Shunk, Stephen A. 2012. A new forest fire paradigm: The need for high-severity fires. The Wildlife Professional. Winter 2012: 46-49. During the 2012 fire season from June through August, wildfires in the drought-stricken western and central United States burned more than 3.6 million acres of forest and shrubland. In the hot, dry, windy conditions seen that season, a single spark can start an understory fire that ascends into the canopies of overstory trees and results in a ‘mega-fire’ that escapes control efforts,...

The Duke University FACE facility is located near Chapel Hill, in Orange County, North Carolina on the eastern edge of the North Carolina piedmont. The initial prototype plot was established in June, 1994 and eleven additional treatment plots were activated in August 1996 and operated until October, 2010. To date, 263 publications have reported on results from the experiment. CO2 enrichment was discontinued in October 2010 and the final harvest began. Trees for the decomposition study were harvested in early 2011. Later that year, the logs of three diameter classes representing different...

A hydrologic research network was established in Arizona in the 1950s and 1960s called the Arizona Watershed Program (Baker et al. 1999). It consisted of a number of public agencies and private groups interested in obtaining more water for future economic growth while maintaining the State's watersheds in good condition. As part of the Program. paired watershed studies were established at Workman Creek, Three-Bar, Whitespar, Mingus Mountain, Battle Flat. Beaver Creek, Castle Creek, Willow Creek, Thomas Creek, Seven Springs, and Stermer Ridge. Initially, most of the research emphasis was on...

The most sustainable and best quality fresh water sources in the world originate in forested watersheds (Dissmeyer 2000, Brooks et al. 2003, Barten and Ernst 2004). The biological, chemical, and physical characteristics of forest soils are particularly well suited to delivering high quality water to streams, and moderating the climatic extremes which affect stream hydrology and water quality (Neary et al. 2009). Forest soils are usually characterized by high porosities, low bulk density, and high saturated hydraulic conductivities and infiltration rates (Neary 2011). Consequently, surface...

Chestnut blight, incited by Cryphonectria parasistica, devastated American chestnut (Castanea dentata (Borkh.) Marsh) in the first half of the 20th century, killing approximately 4 billion dominant and codominant trees. Millions of small sprouts still persist throughout the botanical range of C. dentata. Most are not infected and do not flower, except for short periods, before the shoot is killed by blight. Around the fringes of the botanical range, isolated trees can escape infection for prolonged periods, reaching diameters of about 50 cm at breast height (dbh). In the heart of the...

The emerald ash borer (Agrilus plannipennis; EAB) is a phloem-feeding beetle that is endemic to Asia. It was discovered in North America in 2002, found almost simultaneously near Detroit, Michigan and Windsor, Ontario, Canada. Adult beetles feed on ash (Fraxinus spp.) foliage, but larval feeding on phloem, cambium, and outer xylem is far more detrimental because it effectively girdles the tree, disrupting nutrient and water transport and ultimately killing the tree. As of 2007, it was estimated that 53 million ash trees had been killed by EAB in North America (Kovacs et al. 2010). Potential...

Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg., a forest tree native to the tropical rain forests of Central and South America, has only been recently domesticated outside its natural range of distribution. Almost all of the commercially cultivated clones of H. brasiliensis represent a very narrow genetic base since they originated through hybridization or selection from a few seedlings of so called Wickham germplasm. Hence, the commercial rubber cultivation, due to their genetic vulnerability, is under a constant threat of attack by native as well as exotic diseases and insects....

Seeding is a key management tool for arid rangeland. In these systems, however, seeded species often fail to establish. A recent study inWyoming big sagebrush steppe suggested that over 90% of seeded native grass individuals die before seedlings emerged. This current study examines the timing and rate of seed germination, seedling emergence, and seedling death related to this demographic bottleneck. We seeded monocultures of two native perennial bunchgrasses, Pseudoroegenaria spicata (Pursh) A. Love and Elymus elymoides (Raf.) Swezey, and one introduced bunchgrass, Agropyron desertorum...
