An analysis of the timber situation in the United States: 1952 to 2050.

National inventories of down and dead woody material forest carbon stocks in the United States: Challenges and opportunities

“…A US C budget model, FORCARB (Plantinga and Birdsey, 1993;Heath and Birdsey, 1993), had been developed and linked to a USDA Forest Service timber modeling projection system used for national planning in the US (Mills and Kincaid, 1992;Ince, 1994;Haynes, 2003). FORCARB used the traditional forest inventory information from ATLAS (a timber inventory projection system; Mills and Kincaid, 1992), converting volumes to tree C and area to soil C based on forest type, region, productivity, and regeneration type of the management units through a projection period of 1990-2040, with inventory information reported at 10-or 5-year increments.…”

Comparisons of carbon pools and economic profitability for managed ponderosa pine stands in Wyoming, USA

“…Merchantable timber from the final harvest was calculated using conversion factors presented in Table 2. An estimated price of timber in 2035 was obtained from Haynes (2003). All costs and revenues were converted into 2006 real US dollars using the all commodity producer price index to facilitate a comparison between the net revenues generated by the different management practices.…”

Minnesota's forests 1999-2003 (Part A)

“…Preliminary findings from the 2002 U.S. timber assessment (Haynes 2003) indicate that approximately 15 to 20 million acres of U.S. forest land could be converted to urban and developed uses over the next 50 years. Such land use conversions could result from residential development in forested landscapes, as the U.S. population is estimated to grow by another 126 million people.…”

“…The decrease in the total amount of interior forest in Minnesota indicates a possible negative trend in forest health. Although some wildlife species benefit from fragmentation and the resulting increase in forest edge, fragmentation can have adverse impacts on the forest including the loss of biodiversity, increased populations of invasive and nonnative species, changes in biotic and abiotic environments, changing landowner objectives, and decreased or more costly natural resources as in the case of timber management (Haynes 2003). Housing development is a major cause of habitat loss and fragmentation, due in part to new roads built to access homes (Radeloff et al 2005a).…”

“…Supply assumptions include land use, area of timberland, investment in land management by different owners, adjustments for timber removals, and harvest from public timberlands." A complete list of assumptions used in developing these projections can be found in chapter 2 of "An Analysis of the Timber Situation in the United States: 1952 to 2050" (Haynes 2003). …”
