“…This is justified by studies that indicate that NIPFs have minimum acceptable bid ranges that influence their decision making (see [71, 189]) and is intuitive in the case of registered commercial forests managed as industrial forests. However, the limited harvest rates in the region, with growth exceeding harvesting [206], justify a conservative approach in the model to harvest decision making since harvesting should not exceed these growth rates. Finally, materials published by developers of the IH 2 biorefinery indicate they believe that existing harvesting activities will be sufficient to supply the facility (see [121]).…”

“…Forests in the WUP are predominantly even-aged, medium-to-fully stocked, and of sufficient DBH to be harvested as saw logs [206]. However, individual parcels and stands may have been previously harvested, have different conditions affecting growth, and so forth, which influence the decision to harvest.…”

“…However, individual parcels and stands may have been previously harvested, have different conditions affecting growth, and so forth, which influence the decision to harvest. As a result, the model is initialized with a forest that closely resembles the current state of forests in the region as determined by land cover data [103,207] and U.S. Forest Service reports [206]. Following initialization of the environment, it is assumed that stands will grow in a matter consistent with the average rate of growth for the species.…”

“…Markups are commonly used by contractors to avoid cost overburdens [216], and these may also impact logging operations (e.g., equipment repairs, fuel fluctuations, insurance, etc.). Second, annual harvest limits are based upon total timber harvests in the WUP region; less harvests that took place in Ottawa National Forest (see Table S3, Electronic Supplementary Material; [206,217]). Data from 2014 sales was used to ensure conformance with the aggregated data on Michigan forest removals.…”

“…The total area of NLCD pixels was then tabulated and the forest allocation was then calculated (see Table S2, Electronic Supplementary Material). Harvest removals [206] were then adjusted to exclude known harvesting that took place in Ottawa National Forest [217].…”

Expanding wildland-urban interface alters forest structure and landscape context in the northern United States

The wildland-urban interface (WUI), where housing intermingles with wildland vegetation, is the fastest-growing land use type in the United States. Given the ecological and social benefits of forest ecosystems, there is a growing need to more fully understand how such development alters the landscape context and structure of these WUI forests. In a space-for-time analysis we utilized land cover data, forest inventory plots, and housing density data over time to examine differences in forest characteristics of the northern US across three WUI change classes: (1) forest that has been in WUI housing density levels since at least 1990 (old-WUI), (2) forest where development crossed the WUI housing density threshold after 1990 (new-WUI), and (3) forest with little to no housing development (non-WUI). Of the 184 million acres of forest in the study area, 34 million acres (19%) were in old-WUI, 12 million acres (7%) were new-WUI, and 136 million acres (74%) were non-WUI. In general, as areas transitioned from non-WUI to newer WUI to older more established WUI, the forest was associated with decreased spatial integrity, increased forest-developed edges, and lower proportions of forest in the surrounding landscape. Forest in the WUI had greater carbon storage, with greater aboveground biomass, relative stand density, and more live trees per hectare than non-WUI forest, suggesting greater capacity to sequester carbon compared to non-WUI forest. At the same time, WUI forest also had significantly reduced structural diversity compared to non-WUI forest, with fewer saplings, seedlings, and dead trees per hectare. Forest that more recently crossed the WUI housing density threshold appeared to be on a trajectory towards that of old-WUI forest. These differences in forest structure across the northern US suggest reduced capacity for forest regeneration in the WUI and the potential for changes in other ecological functions.

The American woodcock (Scolopax minor; hereafter, woodcock) is an important game species in central and eastern North America. In this paper, we argue that the wildlife community should consider several novel ideas. At the landscape level, one of the most effective ways to perpetuate aspen (Populus spp.) forests is through commercial forest management. Aspen underpins the major forest products industries: its fiber is highly sought after for pulp, paper, oriented strand board and other engineered lumber products, and lumber. The most cost-effective and reliable way to maintain woodcock habitat is through commercial forest management and through periodic timber harvests. Non-commercial habitat management is possible but expensive and time-consuming. Support for forest products industry business attraction and development is good for woodcock habitat, good for local communities, and good for local economies. We recommend that the wildlife community consider greater involvement in the broader social discussion over the use of wood products, and be actively engaged in discussions involving economic development and energy use by the forest products industry at the state and local level.
