Development near Oregon, Washington public forests

04.12.2013
Private development along the edges of most public forests in Oregon and Washington more than doubled since the 1970s, a new study conducted by the U.S. Forest Service Pacific's Northwest (PNW) Research Station has found.

The study, which used aerial photography to inventory structures at the fringes of public forests, is the first to look at development trends in the two states before and after the enactment of land use laws.

The findings are reported in Changes in Development Near Public Forest Lands in Oregon and Washington, 1974-2005: Implications for Management, a report published by the PNW Station.

"Although public forests are not necessarily directly subject to development, they still face management issues at their edges because of indirect development pressure," said David Azuma, a research forester at the station who led the study.

In Oregon and Washington, about half of all forest lands are publicly owned and managed by the Forest Service, Bureau of Land Management, Oregon Department of Forestry, and Washington Department of Natural Resources. Using a fine-scale grid of points on air photos across the two states, Azuma and colleagues classified areas outside of federal lands for land use and then recorded the number of structures within a 321-meter radius of each of these points.

"Quantifying the increases in structures in areas that have not been converted in land use can serve as a surrogate for the broader risk associated with development near public lands," Azuma said.

Among the study's findings:

Structure density within 1 kilometer of public forest more than doubled for each of the public owner groups between the 1970s and the mid-2000s.

Washington Department of Natural Resources lands are the most developed along their edges, with an average of 11 structures per square kilometer within 1 kilometer of their land – a rate that is more than twice that of lands managed by the other public land owners.

In Oregon, the greatest amount of development occurred along the edges of Bureau of Land Management forests, where there is an average of 4.4 structures per square kilometer within 1 kilometer and 19.5 structures within 2 to 5 kilometers of their land.

The greatest increases in structure density along public forest borders occurred in Pierce, King, Snohomish, and Clark Counties in Washington, and in Deschutes County in Oregon.

The study's findings suggest that areas with increasing development should probably expect continued development. The work can help agencies that manage public forests to better plan for management options at the edges of their land.

The report is available online (at http://www.treesearch.fs.fed.us/pubs/45205) and in print by request. Printed copies of the report will be available after December 20 and can be requested by emailing pnw_pnwpubs@fs.fed.us or by calling (503) 261-1211 and referencing "PNW-RP-596."

The Pacific Northwest Research Station—headquartered in Portland, Ore.—generates and communicates scientific knowledge that helps people make informed choices about natural resources and the environment. The station has 11 laboratories and centers located in Alaska, Washington, and Oregon and about 400 employees. Learn more online at http://www.fs.fed.us/pnw.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
