Evaluating Human Pressure On Protected Areas In East Africa, Bailey M. Ytterdahl

Student Publications

Protected areas (PAs) are crucial to achieving effective conservation goals and mitigate the loss of biodiversity. I investigated the following research questions: How does human pressure threaten PAs in East Africa? Is human pressure associated with the factors of country, ecosystem characteristics, size, or governance type of a PA? For this study, I used a combination of a GIS analysis and case studies to evaluate human pressure on PAs in Tanzania and Kenya. For the GIS analysis, I used 589 terrestrial PAs from the World Database on Protected Areas (WDPA). Within each PA, I summarized the landform, landcover, moisture level, …

Ecosystem Service Trade-Offs In Coral Reefs: A Global Analysis, Megan E. Keene

Student Publications

Coral reefs are biodiversity hotspots that provide humans with extractive ecosystem services like fisheries and non-extractive services like tourism. Though no studies have examined these trade-offs among these services at a global scale, there are now large, open datasets that make this possible. Using these datasets, we asked whether spatial protection and the level of protection (World Database on Protected Areas) impacted coral reef tourism value (Atlas of Ocean Wealth). We also examined whether proximity to regions of high fishing effort, defined as the top 25th percentile of the average annual effort from Global Fishing Watch, impacted tourism values. Since …

North American Breeding Bird Survey Underestimates Regional Bird Richness Compared To Breeding Bird Atlases, Roi Ankori-Karlinsky, Michael Kalyuzhny, Katherine F. Barnes, Andrew M. Wilson, Curtis Flather, Rosalind Renfrew, Joan Walsh, Edna Guk, Ronen Kadmon

Environmental Studies Faculty Publications

Standardized data on large-scale and long-term patterns of species richness are critical for understanding the consequences of natural and anthropogenic changes in the environment. The North American Breeding Bird Survey (BBS) is one of the largest and most widely used sources of such data, but so far, little is known about the degree to which BBS data provide accurate estimates of regional richness. Here, we test this question by comparing estimates of regional richness based on BBS data with spatially and temporally matched estimates based on state Breeding Bird Atlases (BBA). We expected that estimates based on BBA data would …

Commentary: Are National Parks Still Relevant?, Randall K. Wilson

Environmental Studies Faculty Publications

On the occasion of the National Parks centennial comes an irreverent question: Are the parks still relevant?

Famously christened as America's "best idea" by writer Wallace Stegner and reaffirmed in Ken Burns' 2009 PBS documentary, it seems brazen, if not blasphemous, to pose the question. [excerpt]

Crafting A Campus Sustainability Action Plan: A Grassroots Approach, Jolina A. Kenney

Student Publications

In recent decades, colleges and universities have taken a leadership role in developing institution-based Sustainability Action Plans (SAPs). A SAP includes a summation of past achievements, current initiatives, and the prioritized goals and implementation strategies for future action in terms of promoting environmental sustainability. These plans can also serve as pedagogical devices that teach students, staff and faculty important lessons of intentional living, global citizenship, and environmental responsibility. While many plans are adopted as top-down initiatives, there is great value in finding ways to engage the entire campus community in such endeavors at the grassroots level. This project documents a …

Gettysburg College Sustainability Proposal, Joseph W. Boone, Andrea Carson, Sarah F. Hecklau, Erik J. Hughes, Catherine A. Leech, Taylor J. Mcgrath, Nicole L. Moody, Christian I. Neumann, Mary K. Ranii, John D. Ryder, Megan Sherman, Sara W. Tower, Sarah Weinstein

Student Publications

In the fall of 2011, the Environmental Studies capstone class led by Professor Rutherford Platt was asked to write Gettysburg College’s first Sustainability Plan. The goal of the plan was to develop specific sustainable practices for the campus that were related to the three pillars of sustainability: economic, social, and environmental, and how integrating diligent sustainable practices into each of these respected pillars will result in a more conscious campus, community, and future. In 2010, Gettysburg College turned to the Sustainability Tracking Assessment and Rating System (STARS) to quantify the institution’s sustainability efforts, providing a self-check mechanism to encourage sustainability …
