Dehumidification drying equipment is available, but an enclosure must be built to house the equipment and dry the lumber. A dry kiln needs to be operated when it is filled with lumber and forces airflow through the tiers of lumber instead of around the ends or over the top of the stack(s). This construction plan is for an 800 board-foot capacity dry kiln structure that is designed to work with an EBAC LD800TM dehumidification unit. This size is suitable for the small woodworking shop or...AuthorsNeal BennettKeywordsSourceGen. Tech. Rep. NRS-188.

- Woody biomass feedstock that is both high quality and low cost has become increasingly important for the bioenergy and bioproducts industries. Logging generates forest residues – low-quality feedstock – and additional operations that also incur additional costs, such as biomass sorting and treetops processing (BSTP), micro-chipping, and screening, which are required to improve the feedstock’s quality. Considering recent developments in technologies and BSTP to generate high-quality feedstocks, economic models were developed in this study to estimate various forest-residue logistics...AuthorsKamalakanta Sahoo, Edward Bilek, Richard Bergman, Anil R.

- Global positioning system (GPS) telemetry units are now small enough to be deployed on terrestrial and semi-aquatic turtles. Many of these GPS units use snapshot technology which collects raw satellite and timestamp data during brief periods of data recording to minimize size. We evaluated locations from snapshot GPS units in stationary tests and on wood turtles (Glyptemys insculpta) in northeastern Minnesota. Stationary GPS units were placed in wood turtle habitat to evaluate location accuracy, fix success rate, and directional bias. The GPS fix success rate and accuracy were reduced in...AuthorsMadaline M. Cochrane, Donald J. Brown, Ron A. MoenKeywordsSourceDiversityYear2019
- The leading role of native peoples in natural disaster management within the framework of the Promotion of Food Security and Social Inclusion in the Lempa Region of Western Honduras Program (PROSADE LEMPA) involves: Actions aimed at reducing the imminent risk to remnant forests and the most vulnerablepopulations due to "Natural Disaster" caused by fires and pests. The participation of key actors such as indigenous peoples, government, civil society,private enterprise and international cooperation in fire management. Systematization of PROSADE LEMPA’s experience with vulnerable populations...AuthorsArnaldo BuesoSourceGen. Tech. Rep. PSW-GTR-261 (English).

- Applied Meteorology is an important and rapidly growing field. This chapter concludes the three-chapter series of this monograph describing how meteorology information can be used to serve society’s needs, while at the same time advancing our understanding of the basics of the science. This chapter continues along the lines of part II of this series by discussing ways that meteorology and climate information can help improve the output of the agriculture and food security sector. It also discusses how agriculture alters climate and its long-term implications. It finally pulls together...AuthorsSue Ellen Haupt, Branko Kosovic, Scott W.

- Tree vegetation was evaluated through the establishment of 14 Permanent Monitoring Plots (PMP) in "Cerro Azul" Meambar National Park (PANACAM), located in central Honduras. The plots were distributed in four elevational ranges (900 - 1,200, 1,200 - 1,500; 1,500 - 1,800 and 1,800 - 2,080 m), where a total of 1,896 individuals belonging to 231 species, 135 genera and 69 families were recorded. No significant differences were found for richness, diversity and structure between the elevational ranges; however, there is a low similarity in species composition between ranges, where those that...AuthorsLuis Bejarano, Antonio ChavarríaSourceGen.

- The limited availability of resources for wildfire management necessitates prioritizing forest areas for protection. For this purpose, criteria such as fire risk are used to generate thematic maps intended to support decision-making. However, prior to this, the information must be validated under a statistically robust process. Unfortunately, no such process currently exists, so it must be formulated from the most basic aspect, which is the definition of the sampling unit. This was the objective of this study, where different-sized reference sites (RSs) were tested under four sampling...AuthorsJosé G. Flores Garnica, Alejandra Macías, Uri D. CasillasKeywordsSourceGen.

- Even when they account for a large part of damages caused by forest fires on environmental and landscape services they are seldom included in the valuation of damage assessments. Some fires within natural parks have caused significantly larger impacts on these environmental and landscape services (nonmarket) than on market services. The economic valuation of forest fires impacts on environmental and landscape services requires indirect valuation techniques like the travel cost or contingent valuation methods. There are differences on welfare estimates depending on the geographic zone...AuthorsJuan Ramón Molina, Francisco Rodríguez y SilvaSourceGen. Tech. Rep. PSW-GTR-261 (English).

- Generation of information about fire environments and forest fuel beds is essential to know the behavior of wildfires. Developing experimental models in laboratories can be costly and time-consuming. One alternative is to take advantage of the empirical knowledge of people with experience in fire management and wildfire fighting. In order to collect empirical information on the fire environment to evaluate and describe forest fuel beds in different ecosystems in Mexico, four participatory workshops were held. These workshops were held in four venues covering the North, Central, West and...AuthorsHéctor Leonardo Martínez-Torres, Karla Argelia Oceguera-Salazar, Erika Garduño-Mendoza, Teodoro Carlón-Allende, Enrique Jardel-Pelaez, Shatya D.

- In the field of geographic information systems (GIS) there are certain tasks that are performed repetitively and are thus sometimes monotonous, where it is necessary to structure, integrate and analyze a series of georeferenced information, which, however, always carries the same sequence. Therefore, we developed a sequential model which allows automating certain processes in the definition of priority wildfire protection areas. For this, we used the Model Builder tool (ArcGis), which is based on a visual programming language that allows structuring the sequence of processes. To illustrate...AuthorsJosé German Flores Garnica, Uri David Casillas Díaz, Alejandra Macías. MuroKeywordsSourceGen. Tech. Rep. PSW-GTR-261 (English).
