    The H.J. Andrews Experimental Forest Oral History Collection is comprised of interviews with U.S. Forest Service employees, Oregon State University faculty, and other individuals involved with the creation, development and use of the H.J. Andrews Experimental Forest, which is located in the west-central Oregon Cascades. SELECTED REFERENCES Fire Effects on Soil, Water and Air Aber, J. D., and Melillo, J. M. Terrestrial Ecosystems. Saunders College Publishing. Molly Charnes, a teacher in the HJA Research Experience for Teachers program, created a game entitled: H.J. Andrews Experimental Forest Tea Party, that includes a “deck” of organism role cards with great photos and notes on natural history. These are biota of Ellie’s forest, and in addition to the Tea Party game, could be used in a variety of ways to explore questions of biota, habitats.

Vegetation research uses data from a large network of permanent study plots across a wide range of stand ages, habitats, management histories, and disturbance types in Oregon and Washington and data from long-term monitoring of experimental watersheds at the H.J.

Andrews Experimental Forest. From June 15 and JI was the Writer/Scholar-in-Residence at the H. Andrews Experimental Forest in Blue River, Oregon.* I spent a month at the Andrews walking and napping in the old-growth forests and flower-infused meadows, writing creatively and scholarly, and photographing the landscape large and small.

Here are my (mostly) daily reflections,1,2 sparked. First established in as a US Forest Service Experimental Forest, the HJ Andrews is a 16,acre ecological research site in Oregon’s beautiful western Cascades Mountains. Supported by Oregon State University and the US Forest Service, the research program is part of the Long-Term Ecological Research network, funded by the National.

The Andrews LTER program has its roots in the establishment of the H. Andrews Experimental Forest by the US Forest Service in This began two decades of predominantly Forest Service research on the management of watersheds, soils, and vegetation.

Seasonal and long-term changes in the water balance of conifer logs during the first 8 years of decomposition were studied in an old-growth Pseudotsuga/Tsuga forest in the Oregon Cascade Mountains.

Measurements were made of the moisture content of outer bark, inner bark, sapwood, and heartwood and of the flow of water into and out of logs of four species (Abies amabilis, Cited by: New long-term experiments were established under LTER, such as the monumental year log decomposition study established in Since the s, Andrews Forest scientists have developed landscape level studies, and have begun testing methods of ecosystem management.

This study took advantage of an ongoing litter decomposition experiment at the H. Andrews Experimental Forest (HJA), Oregon, United States. About 90% of the area’s annual precipitation falls from October to April, with the wettest period in December and peak drought conditions occurring in by: Long-term Ecological Reflections Program: Arts, Humanities, and Science in Alliance.

In a creative variety of programs, writers, artists, scientists and thought-leaders of many fields come together at the H. Andrews Research Forest to reflect on the meaning and significance of the ancient forest ecosystem, as the forest—and its relation to human culture—evolves over time.

Decomposition of 13 C‐labeled dissolved organic carbon (DOC) produced in two marine diatom blooms was followed for yr with large volume (20 liter) incubations performed in the dark.

The 13 C tracer was used to partition decomposition dynamics of the fresh diatom‐derived DOC and the turnover of background DOC from Woods Hole Harbor. DOC from Woods Hole Harbor proved largely refractory Cited by: H.J. ANDREWS EXPERIMENTAL FOREST LTER SITE Site Name: H.J.

Forest Service. In it became a Long Term Ecological Research site of the National Science Foundation. The influence of inorganic nitrogen (N) inputs on decomposition is poorly understood.

Some prior studies suggest that N may reduce the decomposition of substrates with high concentrations of lignin via inhibitory effects on the activity of lignin‐degrading enzymes, although such inhibition has not always been by: USDA Forest Service at the H.J.

Abstract: LTER - Long-Term Ecological Research Program/H.J. Andrews Forest (AND) LTER/AND [Summary adapted from the LTER Core Data Set Catalog]: This study examines and contrasts the decay of small logs in a stream channel to those on an upland site.

It also examines the movement of small logs in a third- to fourth-order stream. The book consists of 22 chapters and covers a wide range of topics including descriptions of various long-term experiments in the USA, Australia, Eastern Europe and Africa, as well as studies at Rothamsted.
