The objective of this section is to build a library of local Irish reserach relevant to Leave No Trace Ireland. Many research projects are currently underway accross Ireland among a variety of research themes. Please contact email@example.com for more details. In the meantime, we have included Leave No Trace research from the US below.
Leave No Trace focused Research from Leave No Trace America:
The Leave No Trace Center for Outdoor Ethics is data-driven in its approach to teaching people how to enjoy the outdoors responsibly. Whether conducting its own studies, or drawing from the findings of recent research, the Center utilises empirical data to ensure strong education programs, high-quality training, and sound best practices.
Existing Leave No Trace scientific literature largely aligns with the disciplines of recreation ecology, and human dimensions of natural resources (HDNR). Recreation ecology is a field of study that examines the impact of visitors to protected areas, and has provided the underpinning for Leave No Trace messaging because of its focus on recreation-related impacts. However, one of the most important causes of visitor-created impacts is impactful visitor behavior, which more closely aligns with human dimensions. HDNR research seeks to interpret humans’ attitudes towards, perceptions of, and interactions with the ecosystem. Leave No Trace-focused research of this kind is limited but increasing.
The majority of human dimensions research focused on Leave No Trace has evaluated educational effectiveness by examining communication strategies aimed at increasing knowledge to influence the behavior of recreationists. For example, studies have evaluated strategies to diminish litter (Cialdini, 1996), minimize human and wildlife conflict (Hockett & Hall, 2007), curtail removal of natural objects (Widner-Ward & Roggenbuck, 2003), and discourage off-trail hiking (Winter, 2006). However, few studies have explicitly addressed Leave No Trace and have otherwise focused on nonspecific minimum impact behaviors. An even smaller subset of HDNR studies focused on Leave No Trace has explored visitors to frontcountry areas (see Jones & Bruyere, 2004; Jones & Lowry, 2004; Leung & Attarian, 2003; Mertz, 2002; Taff et al., 2014).
Many of the previous investigations have primarily utilized knowledge of minimum-impact practices as a measure of Leave No Trace effectiveness. While some relationship does exist, a primary shortcoming of focusing on knowledge is that the assumption of a linear relationship between environmental knowledge and behavior is largely false. In other words, increasing knowledge about environmental impact does not necessarily equate to a change in an individual’s behavior.
Contemporary social scientists have begun exploring the influence that values, beliefs, attitudes, and other factors play in determining the behavior of outdoor enthusiasts within the context of Leave No Trace, based largely upon behavioral theory. Additionally, recent research has started examining the perceptions of frontcountry visitors with respect to behavioral theory and Leave No Trace. This is an important consideration in Leave No Trace-related research given the theoretical foundations that suggest attitudes are one of the important influences on behavior.
Recently the Center has been using an approach to explore Leave No Trace-related behaviors of interest which has primarily consisted of visitor observation coupled with paired survey data. This methodology provides the opportunity to ask study participants what they would do while also observing what they actually do in a park or protected area context. Through a multi-method, experimental design including unobtrusive observation, and paired visitor survey data collection, these kinds of studies allow for the examination of attitudes and motivations that lead to a reduction of recreation-related impact.
Latest Research Findings:
Undesignated Trail Management and Messaging Study
Current research efforts:
Bouldering Research –
Bouldering in Rocky Mountain National Park has become increasingly popular, and the Leave No Trace Center for Outdoor Ethics is conducted research which aimed to gain a baseline understanding of boulderers’ attitudes and behaviors toward the climbing environment, other boulderers, and other park visitors. Through a grant from the Access Fund Center researchers collected data for a 10-day period in October 2015. Though data analysis has just begun, data gathered from this study will be used to develop awareness and education programs and materials to help boulderers minimize their potential impacts to natural, cultural, and social resources in Rocky Mountain National Park and beyond. Results from the study may also help inform park officials who are making future management decisions for bouldering activities.
Undesignated Trail Use Management Research –
The Center, in conjunction with Penn State University, completed data collection in the summer of 2015 for a study focused on curbing undesignated trail use in natural areas. Due to its methodology, the study is unique in the Leave No Trace scientific literature. The experimental design utilized both visitor surveys and field observation of trail users responses to a suite of five treatments and controls designed to keep trail users on
agency-designated trails. The data, collected over a 30-day period, included over 2200 observations of individual trail users, and garnered nearly 150 paired survey responses, which will allow for comparative analysis of reported behavior and observed behavior. Data analysis began this fall, followed by a full technical report in spring 2016.
Youth Focused Research –
The Center has partnered with Penn State University researchers to conduct a youth-focused study in conjunction with the Outdoor School (ODS) at the Shavers Creek Environmental Learning Center in Pennsylvania. The purpose of the proposed research is to gain understanding of youth perceptions toward Leave No Trace educational practices promoted through the Center’s Promoting Environmental Awareness in Kids (PEAK) program, and associated behaviors, by:
* Specifically examining Leave No Trace-related behaviors with youth at Penn State’s Shaver’s Creek Environmental Learning Center’s – Outdoor School, to determine the effectiveness of PEAK-based educational strategies.
* Specifically examining attitudes and knowledge of specific Leave No Trace practices among youth at ODS.
This study will employ an experimental, equivalent control-group design. Behavior will be measured through direct observation. Additionally, self-reported appraisals will be collected to measure attitudes toward, and knowledge of, the specific PEAK-based Leave No Trace behavior in question. Data collection will occur in spring 2016.
