Comparing vegetative effects of domestic stock and feral goats as ungulate herbivores in Waingaro: Year 1 results

Fencing remnant native vegetation has become a widespread activity throughout New Zealand to increase native biodiversity. However, there have not been many studies to show if this is an effective approach when feral goats (Capra hircus) are present. The present study investigated the short-term effects on dominant trees and shrubs of fencing on a private property in Waingaro, New Zealand. Two permanent plots were analyzed, one in a fenced covenanted area with feral goats present and one in an unfenced area with cows, sheep, and feral goats present. Both plots were dominated by a canopy of kanuka (Kunzea ericoides), a midstory of silver tree fern (Cyathea dealbata) and an understory of divaricating coprosma's (Coprosma rhamnoides and Coprosma spathulata)

Recreation Benefits of U.S. Parks

Over 90 percent of people living in the United States participate in some type of outdoor recreation, from walking the dog to rock climbing. These activities increase a person’s well-being and are examples of recreation benefits. These benefits can be measured by using a variety of available techniques to calculate consumer surplus values. Consumer surplus values for recreation in U.S. parks were collated from an extensive literature review. Studies conducted between 1967 and 2003 yielded over 1,200 observations of non-market benefits. From this meta-analysis, it was determined that an average day of recreation in U.S. parks provide people with a non-market benefit of $60.50/day (2006 US$). With an estimated 924 million visitor days, the benefit of outdoor recreation on federal park lands during 2006 was estimated at $54.7 billion dollars. This analysis did not include state, county, and city parks, and hence the total benefit of outdoor recreation in all U.S. parks would be significantly higher

Understanding stakeholder values using cluster analysis

The K-Means and Ward’s Clustering procedures were used to categorize value similarities among respondents of a public land management survey. The clustering procedures resulted in two respondent groupings: an anthropocentrically focused group and an ecocentrically focused group. While previous studies have suggested that anthropocentric and ecocentric groups are very different, this study revealed many similarities. Similarities between groups included a strong feeling towards public land and national forest existence as well as the importance of considering both current and future generations when making management decisions for public land. It is recommended that land managers take these similarities into account when making management decisions. It is important to note that using the Ward’s procedure for clustering produced more consistent groupings than the K-Means procedure and is therefore recommended when clustering survey data. K-Means only showed consistency with datasets of over 500 observations

US Park recreation values (1968-2003): A review of the literature

The results of outdoor recreation consumer surplus studies for national parks, national forests, state parks and state forests in the United States from 1968 through 2003 are compared and analyzed across activity type, locational region, and park designation. The resulting data set includes 1,229 observations, spanning 36 years, 28 types of activities, and 106 locations. All consumer surplus data were converted to 2006 United States dollars per person per day for comparison purposes. It was discovered that activity and park type played a significant role in consumer surplus values. Activities such as mountain biking, windsurfing, and rock-climbing were among the highest valued activities while visiting environmental education centers was the lowest. When comparing park types, it was found that on average, activities at National Parks had higher values than national forests, state parks, or state forests. This meta-analysis is the most extensive literature review in the history of non-market consumer surplus values for outdoor recreation in the United States ever conducted and should prove beneficial to anyone seeking information on outdoor recreation studies as well as those wishing to conduct a benefit transfer analysis for their own land management area

A summary of ecosystem service economic valuation methods and recommendations for future studies

This short working paper summarizes ecosystem service economic valuation methods. The paper begins with an introduction to ecosystem services, and then describes the various methods that can be used to value them. An extensive literature review was carried out, illustrating those ecosystem service studies that attempted to value three or more ecosystem services using original data and more than one valuation method. Recommendations are then offered on how to conduct ecosystem service valuation studies

The relationship between well-being and wildfire

In this study, the well-being evaluation method, a technique for measuring individual utility, was used to study how people in the wildland urban interface of Colorado (USA) felt about their lives before and after two hypothetical wildfire scenarios. Variables such as age, family size, fire frequency, and property value were found to affect initial well-being levels. However, if a wildfire were to occur, many variables that initially affected well-being were no longer significant. It was found that after wildfire, the frequency of wildfire occurrence became the most important influence on well-being. These results have several implications for wildfire managers. First, the well-being of Colorado wildland urban interface residents would be enhanced by a reduction in the frequency of high-intensity wildfires. Secondly, an extremely high percentage of respondents were in favor of prescribed burning. Therefore, the reduction of high-intensity fires could not only be accomplished by conducting a rotation of prescribed fires, but that prescribed burning would be accepted by the public living in the wildland urban interface

The link between perceived and actual wildfire danger: An economic and spatial analysis study in Colorado (USA)

Over the last 20 years, costs for wildfire initial attack in the U.S. have increased significantly. The increased cost relates to wildfire suppression practices as well as the growing number of wildland urban interface (WUI) homes. Requiring WUI residents to pay an annual tax for their wildfire risk would lower costs to the general taxpayer. Willingness-to-pay (WTP) for wildfire prevention, in relation to both perceived and actual wildfire danger, was the focus of this study. Colorado WUI residents had a high awareness of wildfire risk and were willing to pay over $400 annually to reduce this risk. Respondents beliefs about wildfire frequency were comparable to the original natural wildfire regimes of their areas pre-European settlement

Valuing ecosystem services: A new paradigm shift

The ways in which economists value natural resources has been, and continues to be, a constantly evolving process. At first, only transactions that took place in the marketplace were considered. However, it was not long until it was realised that this concept was an incomplete way to value natural resources and hence the concept of non-market valuation was introduced. These non-market valuation methodologies prevailed for about 50 or 60 years, but, at the present time, it is being realised that the current methodologies are incomplete and it is time for another new paradigm shift. The market and non-market valuation calculations currently used only include anthropocentric (human related) values and have omitted ecocentric ecosystem service values such as the pollination of crops that takes place by bees and flies. The question we are posed with now is how to calculate the true value for ecosystem services in given this new paradigm shift

Is There a Link Between Actual and Perceived Wildfire Danger?

Over the last 20 years, costs for wildfire initial attack in the U.S. have increased significantly. The increased cost relates to wildfire suppression practices as well as the growing number of wildland urban interface (WUI) homes. Requiring WUI residents to pay an annual tax for their wildfire risk would lower costs to the general taxpayer. Willingness-to-pay (WTP) for wildfire prevention, in relation to both perceived and actual wildfire danger, was the focus of this study. Colorado WUI residents had a high awareness of wildfire risk and were willing to pay over $400 annually to reduce this risk. Respondents beliefs about wildfire frequency were comparable to the original natural wildfire regimes of their areas pre-European settlement.GIS, wildfire risk, stakeholder, contingent valuation, Colorado, Resource /Energy Economics and Policy, Risk and Uncertainty,

The connection between biodiversity and well-being: A New Zealand case study

The link between human well-being and biodiversity has not been well studied and was therefore the goal of this research project. Focus was placed on an increase in New Zealand native biodiversity, by an increase in the number of native trees and shrubs being planted on public lands. An increase in well-being occurred in response to an increase in native biodiversity for urban residents that have lived in their current home for less than six years. Responses were also affected by household income, whether a person was self employed and their level of education. We believe this information will be useful in targeting future community participants for voluntary biodiversity projects
