Pb1607 Landowner's Guide To Timber Sale Contracts, The University Of Tennessee Agricultural Extension Service Dec 2005

Pb1607 Landowner's Guide To Timber Sale Contracts, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

A written timber sale agreement or contract is generally the preferable and safest method of selling timber. A written contract is a legally binding document that protects both the buyer and the seller (the landowner) from misunderstandings that may develop in the absence of such an agreement. A contract will verify the seller’s ownership of the timber to be sold and the absence of liens or other liabilities. There is little legal recourse with verbal agreements. By negotiating a contract, both parties are likely to work out difficulties before they occur and be more pleased with the transaction.

No two …

Sp663 Tree Planting Procedure For Small, Bare-Root Seedings, The University Of Tennessee Agricultural Extension Service Nov 2005

Sp663 Tree Planting Procedure For Small, Bare-Root Seedings, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Tree seedlings receive foremost care while growing in a managed nursery: fertile soil; ample moisture; and weed, insect and disease control. Lifting seedlings out of this comfort zone shocks them. Consider: they are dislodged from the soil; their roots are often torn; they are handled several times; they are packaged, shipped, exposed to wind and heat, and placed in planting bags or machine buckets; their roots are unveiled to open air; and they are often replanted in harsh soil where they are left to high temperatures with the hope of adequate precipitation for sustenance through the first few growing seasons.

Picture This, Gary Bentrup, Gary Wells

USDA Forest Service / UNL Faculty Publications

Despite the use of planting plans and engineering drawings, many landowners find it difficult to conceptualize what a future conservation practice or system will actually look like on their landscape. This lack of understanding can create challenging barriers in the planning process and is exacerbated by the long-term commitment that many conservation systems require from landowners. Landowners often lament if they could only see a picture of the proposed action on their property, then they could make a decision. Fortunately, natural resource professionals have a tool called visual simulations to help address this dilemma.

In 1998, we measured the effects of Hurricane Georges after it passed over long-term research sites in Puerto Rican dry forest. Our primary objectives were to quantify hurricane effects on forest structure, to compare effects in a large tract of forest versus a series of nearby forest fragments, to evaluate short-term response to hurricane disturbance in terms of mortality and sprouting, and to assess the ability of hurricanes to maintain forest structure. We sampled damage from 33 plots (1.3 ha) across a 3000-ha tract of forest as well as in 19 fragments. For stems with 2.5-cm minimum diameter, 1004 stems/ha …

Sp657 Impacts Of Air Pollution On The Urban Forest, The University Of Tennessee Agricultural Extension Service Sep 2005

Sp657 Impacts Of Air Pollution On The Urban Forest, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

An average human breathes around 3,400 gallons of air each day. Included in each breath can be numerous noxious chemicals as well as suspended particles. Consequently, human lungs must cope with this pollution. It is well known that air pollution is hazardous to human health and of enormous concern today. However, the “lungs” of our urban areas, trees growing in and around our cities, must also contend with air pollution. Just as air pollution impacts humans, air pollution affects trees in a variety of ways.

Pollution has long been identified as harmful to trees. Historically, impacts of air pollution were …


Analyses Of High Resolution Hyperspectral Imagery For Characterization Of Ponderosa Pine Woodlands, Cullen R. Robbins Aug 2005

Analyses Of High Resolution Hyperspectral Imagery For Characterization Of Ponderosa Pine Woodlands, Cullen R. Robbins

School of Natural Resources: Dissertations, Theses, and Student Research

The Bessey Unit of the Nebraska National Forest is a planted ponderosa pine forest located in the Nebraska Sand Hills. Planted in the early 20th Century, it provides a unique opportunity to study the effects of ponderosa pine establishment on the surrounding grassland ecosystem and the effects of increasing pine density on the forest ecosystem. It has been hypothesized that there are key levels of canopy cover at which shifts in ecosystem function occur. The goal of this research was to use remotely sensed data to develop a reliable method for estimating canopy cover. More specifically, canopy cover was estimated …


Street Trees In The Urban Forest Canopy: Portland, Oregon, Joseph Poracsky, David Banis Aug 2005

Street Trees In The Urban Forest Canopy: Portland, Oregon, Joseph Poracsky, David Banis

Geography Faculty Publications and Presentations

Attempts to identify the contribution of street trees to the overall urban forest of a city have been rare and lack consensus on how to measure that contribution – percentage of trees, percentage of canopy cover, or percentage of leaf area. The actual numeric values presented in the literature also vary over a broad range and often are based on estimates, extrapolations from aggregated data, or simply stated with no empirical data referenced. This study was undertaken to evaluate the contribution of street trees to canopy in Portland, Oregon. The study involved both visual and digital analysis of multi-band aerial …

Synthesis Of Design Guidelines And Experimental Data For Water Quality Function In Agricultural Landscapes In The Intermountain West, Susan Buffler, Craig Johnson, John Nicholson, Nancy Mesner

USDA Forest Service / UNL Faculty Publications

Currently, there is no scientific literature examining appropriate riparian buffer widths for water quality for streams on private agriculturally dominated lands in arid regions of the Intermountain West. The initial step in this research effort was a review of buffer research as documented in the literature in other physiographic regions of the United States. Research findings on appropriate buffer widths for water quality parameters were synthesized using a matrix format. Differences between arid and non-arid landscape characteristics, soil, topography, vegetation, climate and hydrology and their effect on buffers for water quality were also researched. The combined research findings in this …


Spatial-Temporal Population Dynamics Across Species Range: From Centre To Margin, Qinfeng Guo, Mark Taper, Michele M. Schoeneberger, James R. Brandle Jul 2005

Spatial-Temporal Population Dynamics Across Species Range: From Centre To Margin, Qinfeng Guo, Mark Taper, Michele M. Schoeneberger, James R. Brandle

USDA Forest Service / UNL Faculty Publications

Understanding the boundaries of species’ ranges and the variations in population dynamics from the centre to margin of a species’ range is critical. This study simulated spatial-temporal patterns of birth and death rates and migration across a species’ range in different seasons. Our results demonstrated the importance of dispersal and migration in altering birth and death rates, balancing source and sink habitats, and governing expansion or contraction of species’ ranges in changing environments. We also showed that the multiple equilibria of metapopulations across a species’ range could be easily broken following climatic changes or physical disturbances either local or regional. …


Flow Pathways And Sediment Trapping In A Field-Scale Vegetative Filter, Matthew J. Helmers, Dean E. Eisenhauer, Mike Dosskey, Thomas G. Franti, Jason M. Brothers, Mary Carla Mccullough Jul 2005

Flow Pathways And Sediment Trapping In A Field-Scale Vegetative Filter, Matthew J. Helmers, Dean E. Eisenhauer, Mike Dosskey, Thomas G. Franti, Jason M. Brothers, Mary Carla Mccullough

USDA Forest Service / UNL Faculty Publications

Vegetative filters (VF) are a best management practice installed in many areas to control sediment movement to water bodies. It is commonly assumed that runoff proceeds perpendicularly across a VF as sheet flow. However, there is little research information on natural pathways of water movement and performance of field-scale VF. The objectives of this study were: (1) to quantify the performance of a VF where the flow path is not controlled by artificial borders and flow path lengths are field-scale, and (2) to develop methods to detect and quantify overland flow convergence and divergence in a VF. Our hypothesis is …


Structure And Development Of Pitch Canker Infected Monterey Pine Stands At Año Nuevo, California, Douglas D. Piirto, Sauli Valkonen Jul 2005

Structure And Development Of Pitch Canker Infected Monterey Pine Stands At Año Nuevo, California, Douglas D. Piirto, Sauli Valkonen

Natural Resources Management and Environmental Sciences

The sustainability of indigenous Monterey pine (Pinus radiata D. Don)at Ano Nuevo stands in the central coast of California was examined. The foremost management objective in these stands is to establish and maintain stand structures that ensure a sustainable presence of the species in terms of uneven-aged management. The major threats are the proliferation of shade-tolerant tree species and the pitch canker ( Fusarium circinatum) disease. The study was based on data from 17 systematically placed sample plots, measured once, in one stand with a very high degree of variation in stand structure and species composition. The results …


Modeling Water And Sediment Trapping By Vegetated Filters Using Vfsmod: Comparing Methods For Estimating Infiltration Parameters, Amanda Fox, Dean E. Eisenhauer, Mike Dosskey Jul 2005

Modeling Water And Sediment Trapping By Vegetated Filters Using Vfsmod: Comparing Methods For Estimating Infiltration Parameters, Amanda Fox, Dean E. Eisenhauer, Mike Dosskey

USDA Forest Service / UNL Faculty Publications

Vegetated filters (buffers) are used to intercept overland runoff and reduce sediment and other contaminant loads to streams (Dosskey, 2001). Filters function by reducing runoff velocity and volume, thus enhancing sedimentation and infiltration. lnfiltration is the main mechanism for soluble contaminant removal, but it also plays a role in suspended particle removal. By decreasing the discharge and velocity of overland flow, infiltration causes a decrease in sediment transport capacity, and thus sedimentation is enhanced.

Although the impact of infiltration on soluble and suspended contaminant removal has not been directly documented, many researchers suggest infiltration plays a significant role (Table 1). …

Modeling Water And Sediment Trapping By Vegetated Filters Using Vfsmod: Comparing Methods For Estimating Infiltration Parameters, Amanda L. Fox, Dean E. Eisenhauer, Mike Dosskey

USDA Forest Service / UNL Faculty Publications

The vegetated filter strip model (VFSMOD) was used to investigate the effect of Green- Ampt infiltration parameters (found with different estimation techniques) on sediment and water trapping in vegetated filters of varying soil types. Field-measured and empirically-estimated infiltration parameters were compared. Field saturated hydraulic conductivity (Kfs) values were calculated with an inverse Green-Ampt equation using infiltration data measured in three vegetated filter plots located near Mead Nebraska. Also, three pedotransfer functions (PTFs) were used to empirically generate average Kfs values for each plot, based on percent sand, percent clay, and bulk density. Pedotransfer functions underestimated Kfs …
