Silica Uptake And Release In Live And Decaying Biomass In A Northern Hardwood Forest, Wim Clymans, Daniel J. Conley, John J. Battles, Patrick J. Frings, Mary Margaret Koppers, Gene E. Likens, Chris E. Johnson

Civil and Environmental Engineering

In terrestrial ecosystems, a large portion (20–80%) of the dissolved Si (DSi) in soil solution has passed through vegetation. While the importance of this “terrestrial Si filter” is generally accepted, few data exist on the pools and fluxes of Si in forest vegetation and the rate of release of Si from decomposing plant tissues. We quantified the pools and fluxes of Si through vegetation and coarse woody debris (CWD) in a northern hardwood forest ecosystem (Watershed 6, W6) at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, USA. Previous work suggested that the decomposition of CWD may have significantly …

Agricultural Trade Publications And The 2012 Midwestern U.S. Drought: A Missed Opportunity For Climate Risk Communication, Sarah P. Church, Tonya Haigh, Melissa Widhalm, Silvestre Garcia De Jalon, Nicholas Babin, Stuart Carlton, Michael Dunn, Katie Fagan, Cody L. Knutson, Linda Stalker Prokopy

Department of Forestry & Natural Resources Faculty Publications

The Midwestern United States experienced a devastating drought in 2012, leading to reduced corn and soybean yields and increased instances of pests and disease. Climate change induced weather variability and extremes are expected to increase in the future, and have and will continue to impact the agricultural sector. This study investigated how agricultural trade publications portrayed the 2012 U.S. Midwestern drought, whether climate change was associated with drought, and whether these publications laid out transformative adaptation measures farmers could undertake in order to increase their adaptive capacity for future climate uncertainty. We performed a content analysis of 1000 media reports …

Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell

Professional Agricultural Workers Journal

Abstract

Felling and skidding operations were monitored while clearcut harvesting a 12-acre area of a 14-year old loblolly pine (Pinus taeda) plantation. The study area contained 465 trees per acre for trees 2.0 inches Diameter at Breast Height (DBH) and larger with a Quadratic Mean Diameter (QMD) of 7.26 inches. Two feller-bunchers (tracked and rubber-tired) and two skidders (conventional and large capacity) were paired to create four different harvesting systems which were randomly assigned to 3-acre units for evaluation of production rates and costs. Each system was balanced to determine the number of machines needed to minimize the …

Assisted Tree Migration In North America: Policy Legacies, Enhanced Forest Policy Integration, And Climate Change Adaptation, Adam Wellstead, Michael Howlett

Adam Wellstead

The weight of much expert forest management opinion is that issues such as climate change can be effectively addressed only if forest policy-making moves from a purely sectoral focus and undergoes a shift to a more integrated multi-issue, multi-sector policy-making process. This is because credible adaptation policies in the sector require greatly enhanced multi-sectoral policy integration if they are to succeed. But this requirement may be beyond the capacity of many countries to deliver. This article explores the integration challenges faced by forest policy-making in Canada and the United States and uses the case of Assisted Tree Migration (ATM) to …

The Potential Of Forest Biomass Inversion Based On Vegetation Indices Using Multi-Angle Chris/Proba Data, Qiang Wang, Yong Pang, Zengyuan Li, Guoqing Sun, Erxue Chen, Wenge Ni-Meister

Publications and Research

Multi-angle remote sensing can either be regarded as an added source of uncertainty for variable retrieval, or as a source of additional information, which enhances variable retrieval compared to traditional single-angle observation. However, the magnitude of these angular and band effects for forest structure parameters is difficult to quantify. We used the Discrete Anisotropic Radiative Transfer (DART) model and the Zelig model to simulate the forest canopy Bidirectional Reflectance Distribution Factor (BRDF) in order to build a look-up table, and eight vegetation indices were used to assess the relationship between BRDF and forest biomass in order to find the sensitive …

Systems Thinking In The Forest Service: A Framework To Guide Practical Application For Social-Ecological Management In The Enterprise Program, Megan Kathleen Kmon

Dissertations and Theses

The U.S. Forest Service (USFS) Enterprise Program (EP), which provides fee-for-service consulting services to the USFS, is interested in integrating systems thinking into its service offerings. Despite there being several excellent sources on the range and diversity of systems thinking, no single framework exists that thoroughly yet concisely outlines what systems thinking is along with its deep history, theoretical tenets, and soft and hard approaches. This thesis is an attempt to create such a framework, aimed specifically at practical application in a land management agency, through literature synthesis injected with original analysis. The usefulness of the framework is then tested …

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy that …

Slides: Flpma In Its Historical Context, John D. Leshy

FLPMA Turns 40 (October 21)

Presenter: John D. Leshy, Sunderland Distinguished Professor of Law Emeritus, U.C. Hastings College of the Law

36 slides

This session traces the history of FLPMA including, among other things, its legislative, administrative, and historical antecedents, including for example, the Public Land Law Review Commission’s 1970 report, One Third of Our Nation’s Lands. It then considers FLPMA’s unique public lands policies and requirements and how they are reflected in the BLM’s management of public lands today.

• Why do forest productivity and biomass decline with elevation? To address this question, research to date generally has focused on correlative approaches describing changes in woody growth and biomass with elevation.
  
  
• We present a novel, mechanistic approach to this question by quantifying the autotrophic carbon budget in 16 forest plots along a 3300 m elevation transect in Peru.
  
  
• Low growth rates at high elevations appear primarily driven by low gross primary productivity (GPP), with little shift in either carbon use efficiency (CUE) or allocation of net primary productivity (NPP) between wood, fine roots and canopy. The lack of trend in …

Useful To Usable: Developing Usable Climate Science For Agriculture, Linda S. Prokopy, J Stuart Carlton, Tonya Haigh, Maria Carmen Lemos, Amber Saylor Mase, Melissa Widhalm

Department of Forestry & Natural Resources Faculty Publications

The Useful to Usable (U2U) project was a six-year research and extension project funded by the United States Department of Agriculture to provide both useful and usable climate information for the agricultural (corn) sector in the Midwestern United States. The project adopted an extensive co-production of knowledge and decision-making approach that involved intense iteration with potential end-users, including farmers and a variety of pro- fessional agricultural advisors, through focus groups and surveys, feedback at outreach events, and frequent informal interactions to develop both decision support tools and delivery mechanisms that met stakeholder needs. This overview paper for this special issue …

Critical Review Of The Millennium Project In Nepal, Ashma Vaidya, Audrey L. Mayer

College of Forest Resources and Environmental Science Publications

“Our Common Future” harmonized development policies around a new sustainable development (SD) paradigm, and experts also emphasize the importance of a democratic and equitable approach to define and achieve sustainable development. However, SD targets and indicators are often defined by a suite of experts or a few stakeholder groups, far removed from on-the-ground conditions. The most common expert-led development framework, the United Nations’ Millennium Development Goals (MDGs), promoted one set of targets and indicators for all developing countries. While progress towards these targets was routinely reported at the national scale, these targets may not reflect context-specific sustainable development. We evaluated …

Wassels, Frans Van Den Bergh, David P. Roy, Brian P. Salmon, Karen C. Steenkemp, Bryan Macalister, Derick Swanepoel, Debbie Jewitt

GSCE Faculty Publications

The paper evaluated the Landsat Automated Land Cover Update Mapping (LALCUM) system designed to rapidly update a land cover map to a desired nominal year using a pre-existing reference land cover map. The system uses the Iteratively Reweighted Multivariate Alteration Detection (IRMAD) to identify areas of change and no change. The system then automatically generates large amounts of training samples (n > 1 million) in the no-change areas as input to an optimized Random Forest classifier. Experiments were conducted in the KwaZulu-Natal Province of South Africa using a reference land cover map from 2008, a change mask between 2008 and …

Ico-Mark App Users Guide - Version 1.3, Sean Ma Jeronimo, Emily J. Fales

ICO App

This is the user's guide for the ICO Mark app.

ICO Mark is a tablet- and phone-based application (app) developed for forest managers and forestry field crews to spatially monitor and map forest structure. ICO Mark relies on the Individuals-Clumps-Openings approach to characterizing dry forest spatial patterning, where forests are composed of varying proportions and sizes of individual trees, clumps of trees, and treeless openings. ICO Mark allows users to track individual trees and clumps for both marking pre-harvest, and for monitoring conditions post-harvest.

The Ico Approach To Quantifying And Restoring Forest Spatial Pattern: Implementation Guide, Derek J. Churchill, Sean Ma Jeronimo, Andrew J. Larson, Paul Fischer, Matt C. Dahlgreen, Jerry F. Franklin

ICO App

This document is intended as a “How To” guide for managers and stakeholders wishing to implement the Individual, Clumps, and Openings (ICO) method for silvicultural prescriptions and/or monitoring. This guide is organized into stand-alone chapters. Managers should read and use chapters as they find useful to their own needs.

2014 Maple Business Benchmark, Mark Cannella, Christopher Lindgren, Betsy Miller

UVM Extension Faculty Publications

Maple producers experienced record crop yields matched with sustained strong prices in the 2013 sugaring season. Moving into the 2014 sugaring season producers were aware of slight price declines in the forecast. While producers were still hopeful for a strong sugaring season many managers were concerned that too large of a crop might overwhelm the overall syrup supply and accelerate the price drops (it was not until later in 2014 that producers learn that market price declines would be primarily driven by the Canadian/US currency exchange rates).

The University of Vermont Extension worked with 18 maple producers to complete financial …

The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison

Independent Study Project (ISP) Collection

The water quality and level of contamination of two rivers in a cloud forest ecosystem in the Mejía region of Ecuador, the Tupí River and the Pilatón River were assessed through benthic macroinvertebrate sampling at various sites along the rivers. Many different biological indices were then used to assess water quality at each site. Pollution in the form of grey water, black water, and petroleum negatively impacted the water quality of the both rivers as they pass through the town of La Esperie. Differences in river structure and size also played a role in determining the prevalence of certain benthic …

Partitioning Controls On Amazon Forest Photosynthesis Between Environmental And Biotic Factors At Hourly To Interannual Timescales, Jin Wu, Kaiyu Guan, Matthew Hayek, Natalia Restrepo-Coupe, Kenia T. Wiedemann, Xiangtao Xu, Richard Wehr, Bradley O. Christoffersen, Guofang Miao, Rodrigo Da Silva

Biology Faculty Publications and Presentations

Gross ecosystem productivity (GEP) in tropical forests varies both with the environment and with biotic changes in photosynthetic infrastructure, but our understanding of the relative effects of these factors across timescales is limited. Here, we used a statistical model to partition the variability of seven years of eddy covariance-derived GEP in a central Amazon evergreen forest into two main causes: variation in environmental drivers (solar radiation, diffuse light fraction, and vapor pressure deficit) that interact with model parameters that govern photosynthesis and biotic variation in canopy photosynthetic light-use efficiency associated with changes in the parameters themselves. Our fitted model was …

Exome Genotyping, Linkage Disequilibrium And Population Structure In Loblolly Pine (Pinus Taeda L.), Mengmeng Lu, Konstantin V. Krutovsky, Charles Dana Nelson, Tomasz E. Koralewski, Thomas D. Byram, Carol A. Loopstra

Forest Health Research and Education Center Faculty Publications

Background: Loblolly pine (Pinus taeda L.) is one of the most widely planted and commercially important forest tree species in the USA and worldwide, and is an object of intense genomic research. However, whole genome resequencing in loblolly pine is hampered by its large size and complexity and a lack of a good reference. As a valid and more feasible alternative, entire exome sequencing was hence employed to identify the gene-associated single nucleotide polymorphisms (SNPs) and to genotype the sampled trees.

Results: The exons were captured in the ADEPT2 association mapping population of 375 clonally-propagated loblolly pine trees using …

Prototype For Monitoring And Forecasting Fall Foliage Coloration In Real Time From Satellite Data, Xiaoyang Zhang, Mitchell D. Goldberg, Yunyue Yu

Xiaoyang Zhang

While determining vegetation phenology from the time series of historical satellite data has been widely investigated throughout the last decade, little effort has been devoted to real-time monitoring and short-term forecasting. The latter is more important for numerical weather modeling, ecosystem forecasting, forest and crop management, and health risk warning. In this study we developed a prototype approach for the real-time monitoring and short-term forecasting of fall foliage status (including low coloration, moderate coloration, near-peak coloration, peak coloration, and post-peak coloration) using temporal satellite observations. The algorithm combined the climatology of vegetation phenology and temporally available satellite observations to establish …

Failure To Communicate: Inefficiencies In Voluntary Incentive Programs For Private Forest Owners In Michigan, Mark. D. Rouleau, Jennifer F. Lind-Riehl, Miranda N. Smith, Audrey L. Mayer

College of Forest Resources and Environmental Science Publications

Coordinating forest management across thousands of nonindustrial private forest (NIPF) owners is a difficult yet necessary task for state land management agencies. Voluntary Incentive Programs (VIPs) can coordinate the decentralized activities of these owners in return for services or financial incentives. However, many VIPs typically have low enrollment. Our study investigates the implementation of VIPs to increase forest management coordination among NIPFs in Michigan. We present findings from 20 semi-structured interviews with leaders of state and local land management organizations, and government officials at state natural resource agencies, and contrast their answers with those recorded from 37 interviews of NIPF …
