Greening The Gateway Cities: Summer Internship With The Clark University Human Environment Regional Observatory (Hero) And Massachusetts Department Of Conservation And Recreation (Dcr), Zhiwen Zhu

International Development, Community and Environment (IDCE)

This report provides a detailed account of my internship experience with the Clark University Human-Environment Regional Observatory (HERO) and Massachusetts Department of Conservation and Recreation (DCR) in the summer of 2017. This internship concerns the urban tree health assessment in three ‘Greening the Gateway’ cities in Massachusetts. During the internship, I conducted tree survey field work, database management, mapping, tree survey data analysis and urban tree plantation benefits microclimate simulation. During the internship I worked with the professors and students at Clark University and University of Massachusetts, Amherst, and the staff from Department of Conservation and Recreation (DCR), Worcester Tree …

Seeing Community Through The Trees: Characterizing Resident Response To Urban-Tree Planting Initiatives, Eli Goldman

International Development, Community and Environment (IDCE)

Urban tree planting initiatives have become common across cities in the United States. In order to advocate for sustainable urban forests, managers of urban planting initiatives must adopt a strong community framework, which includes community values in reforestation efforts. Clark University researchers conducted interviews and surveys with residents in six central Massachusetts cities and towns to assess why residents value urban trees and to characterize public response to reforestation efforts. Results indicate residents had positive experiences with tree planting programs, are most likely to value urban trees for aesthetic reasons, and commonly associate change in neighborhood character with Asian Longhorned …

Financial Assessment Of Agricultural Lands At Risk To Coastal Salt Marsh Migration In Relation To Climate Change Induced Sea Level Rise In Dorchester County, Maryland, Jewell Porter

International Development, Community and Environment (IDCE)

The increasing rate and effects of sea level rise is a major environmental concern in the Chesapeake Bay. This paper evaluates the impacts of rising sea level on coastal salt marshes and the surrounding agricultural lands at risk in Dorchester County, Maryland to build off existing environmental monitoring work performed by NOAA’s Sentinel Site Program. The results of the spatial analysis were used to estimate monetary benefits to incentivize farmers to protect these marshes by making their land available for marsh migration to occur. Looking at three scenarios of sea level rise and marsh migration, grain crops (corn, soybeans, and …

A Framework For Evaluating And Enhancing Resilience Integration In Conservation Policy: The Case Of Massachusetts, Kyle Pilkington

International Development, Community and Environment (IDCE)

This paper develops a framework for evaluating conservation policy from the perspective of integrating resilience, using Massachusetts as a case study. After an intensive literature review on the topics of resilience and conservation, five resilience-enhancing attributes were identified: biodiversity, stakeholder engagement, acknowledgement of climate change, multiple species or species interaction focus and ecosystem or environment health. The framework ranks the policies with respect to the effectiveness of following the resilience-enhancing attributes. Three Massachusetts-based conservation policies, Massachusetts Endangered Species Act (MESA), State Wildlife Action Plan (SWAP) and MassWildlife Habitat Management Grant Program (MHMGP), were chosen to demonstrate the evaluative capacity of …

Atole De Maíz Azul: Building Climate-Change Resilience With Local Knowledge/Food Sovereignty In Northern New Mexico, Katherine C.R. Dixon

International Development, Community and Environment (IDCE)

The impacts of climate change in Northern New Mexico will cause a variation in seasonal precipitation and increased drought conditions. Northern New Mexico is home to numerous indigenous and rural-agricultural communities who rely on these water resources for subsistence and cultural practices. They are among the most vulnerable to the impacts of climate change.

This paper investigates the impacts of climate change to Northern New Mexico. It examines the role of participatory methods and local knowledge in building community resilience. This paper is informed primarily through secondary research, and also draws upon a series of personalized interviews from Northern New …

Changes Of Forest Cover And Disturbance Regimes In The Mountain Forests Of The Alps, P. Bebi, R. Seidl, R. Motta, M. Fuhr, D. Firm, F. Krumm, M. Conedera, C. Ginzler, T. Wohlgemuth, Dominik Kulakowski

Geography

Natural disturbances, such as avalanches, snow breakage, insect outbreaks, windthrow or fires shape mountain forests globally. However, in many regions over the past centuries human activities have strongly influenced forest dynamics, especially following natural disturbances, thus limiting our understanding of natural ecological processes, particularly in densely-settled regions. In this contribution we briefly review the current understanding of changes in forest cover, forest structure, and disturbance regimes in the mountain forests across the European Alps over the past millennia. We also quantify changes in forest cover across the entire Alps based on inventory data over the past century. Finally, using the …

A Walk On The Wild Side: Disturbance Dynamics And The Conservation And Management Of European Mountain Forest Ecosystems, Dominik Kulakowski, Rupert Seidl, Jan Holeksa, Timo Kuuluvainen, Thomas A. Nagel, Momchil Panayotov, Miroslav Svoboda, Simon Thorn, Giorgio Vacchiano, Cathy Whitlock, Thomas Wohlgemuth, Peter Bebi

Geography

Mountain forests are among the most important ecosystems in Europe as they support numerous ecological, hydrological, climatic, social, and economic functions. They are unique relatively natural ecosystems consisting of long-lived species in an otherwise densely populated human landscape. Despite this, centuries of intensive forest management in many of these forests have eclipsed evidence of natural processes, especially the role of disturbances in long-term forest dynamics. Recent trends of land abandonment and establishment of protected forests have coincided with a growing interest in managing forests in more natural states. At the same time, the importance of past disturbances highlighted in an …

Is Initial Post-Disturbance Regeneration Indicative Of Longer-Term Trajectories?, Nathan S. Gill, Daniel Jarvis, Thomas T. Veblen, Steward T.A. Pickett, Dominik Kulakowski

Geography

The ability to estimate and model future vegetation dynamics is a central focus of contemporary ecology and is essential for understanding future ecological trajectories. It is therefore critical to understand when the influence of initial post-disturbance regeneration versus stochastic processes dominates long-term post-disturbance ecological processes. Often, conclusions about post-disturbance dynamics are based upon initial regeneration in the years immediately after disturbances. However, the degree to which initial post-disturbance regeneration indicates longer-term trends is likely to be contingent on the types, intensities, and combinations of disturbances, as well as pre-disturbance ecosystem structure and composition. Our relatively limited understanding of why initial …
