Landscapes Are Cornerstones Of Sustainability Programs, Don Spence

Sustainability Conference

Typical American landscapes are not sustainable in an economic or biological framework. The essence of the idea of sustainable growth and development are centered on the idea that those activities are not degrading natural resources or that they are outstrip budgets. A significant piece of any sustainable management plan is tied to how we manage our landscapes, how we use plants; specifically, how much grass there is, and how many native plants there are. Sustainable landscapes should require less chemical and financial inputs, which in the end, saves money and increases the biological value of the land and creates a …

Michigan Tech Publications, Part 1

In order to facilitate hydrological restoration, initiatives have been conducted to promote tree growth in degraded and rewetted peatlands in Indonesia. For these initiatives to be successful, tree seedlings need to be able to survive flooding episodes, with or without shade. We investigated the survival rates and the formation of adventitious roots in the case of four tree species exposed to combinations of different shading and water levels under controlled conditions in a nursery, with artificial rainwater and with peat soil as the medium. The research focused on the following questions (i) whether trees can grow on flooded peat soils; …

Making Forests, Making Communities: An Ethnography Of Reforestation In Monteverde, Costa Rica, Megan Brown

Anthropology Theses and Dissertations

Reforestation is not just planting trees in the ground. More than net increase in forest cover, reforestation is a complex political endeavor undertaken by both humans and non-humans and a popular climate change mitigation tactic. However, little research has examined the dynamics between selection of specific reforestation strategies, health, and community resilience, particularly with attention to entanglements between the lives of both human and non-human forest dwellers. This ethnographic work, based on six months of in-person fieldwork and six months of digital ethnography, examines reforestation and forest relations in Costa Rica’s Monte Verde zone, a region which experienced widespread deforestation, …

Considerations For Establishing Silvopastures On Wooded Sites, Brett Chedzoy, Ashley Conway, John Fike, Kate Macfarland

Agroforestry Notes (USDA-NAC)

Like other conservation and production practices, silvopasture management is not the right fit for every site or every land manager. High quality woodlands with high native species diversity are generally not a good starting point for silvopasture establishment. However, silvopasture provides an opportunity for active forest management on other sites that have been neglected or poorly managed with undesirable species composition, invasive species concerns, and other challenges. In some situations, silvopasture management can be used to aid in ecosystem restoration or fuels mitigation. The land manager and others in the silvopasture team should consider natural resource issues highlighted in this …

From River To Ridge: The Influence Of Elevation And Habitat On Herpetofauna Species Abundance And Diversity In The Llanganates-Sangay Ecological Corridor, Ecuador, Elle Hankin

Independent Study Project (ISP) Collection

Ecuador is one of the most reptile-diverse countries and is home to the highest abundance of amphibians per unit area, with new species being discovered frequently. The Río Pastaza basin is located to the east of the Andes and is characterized by a steep elevational gradient, converging tropical forest types, and high levels of biodiversity and endemicity. Visual surveying was conducted at night for a total of 48 hours in four different study sites to investigate the influence of elevation and habitat on herpetofauna diversity and abundance. Two comparisons were drawn between the four study sites, grouping SKIS and Waska …

Historical And Future Role Of Wilmar Palm Oil In Deforestation Of Indonesian Borneo, Sam Coroniti Iii

Senior Theses

Borneo is one of the most biologically diverse locations on Earth, with thousands of endemic and rare species forming unique and intricate relationships throughout the ecosystems. Orangutans, elephants, leopards, tigers, rhinos, and many more species call this island their home, although population levels for all of the mentioned species have been in seriously decline over recent decades. The loss of primary rainforest that provides the most critical habitat for these species has occurred at the highest rate that has ever been seen on Earth, leading to extreme land conversion and greenhouse gas producing operations. The primary driver of these actions …

Challenges And Opportunities For Restoration Of High-Elevation Andean Peatlands In Ecuador, Esteban Suarez, Segundo Chimbolema, Ricardo Jaramillo, Leo Zurita-Arthos, Paul Arellano, Rodney Chimner, John S. Stanovick, Erik A. Lilleskov

Michigan Tech Publications, Part 1

Páramo peatlands are a regional reservoir of biodiversity and ecosystem services, accumulating large amounts of carbon and buffering water flows. Despite their importance, they have a long history of use and impacts including drainage for agriculture and grazing, and water withdrawal for human uses. Here we present a preliminary assessment of the conservation status of páramo peatlands in Ecuador and, using a case study, discuss peatland restoration as a tool for mitigation and adaptation to the impacts of current climate change. Through a simple index assessing the cumulative presence of signs of human activities on 163 peatland sites, we found …

The area is of vital importance to conservation, as it falls in the ecological corridor between the Sangay and Llanganates national parks. The primary crop produced by the residents of El Placer is naranjilla, and it is cultivated in a variety of manners, mostly with intensive chemical use. The goal of the study was to find out which types of practices were the least harmful to the insect …

A Quantitative Study Of Orchids And Their Proximate Environments Over An Elevational Gradient On The Northern Slope Of Montagne D’Ambre, Hazel Schrader

Independent Study Project (ISP) Collection

This research investigated change in orchid populations and their proximate environments on the Northern slope of Montagne d’Ambre, a subhumid forest in Northern Madagascar. Orchid density, way of life (epiphyte or terrestrial), phenology, and associations were recorded over 100m elevation gradients and between forest types (primary, secondary, dry, and humid forests at the same altitude). Additionally, orchid preferences for certain heights in the forest and DBH of host trees were analyzed. The establishment of 50X20m plots in 100m elevation gradients combined with ground survey yielded significant results demonstrating change along with elevation as well as forest types. Orchid density increased …

Comparing Amphibian Species Diversity And Abundance In Natural Forest And Cacao Agroforest At Finca La Magnita, Changuinola, Bocas Del Toro, Panamá, Lake Barrett

Independent Study Project (ISP) Collection

Amphibians are currently undergoing rapid and drastic biodiversity loss worldwide, largely due to the disease Chytridiomycosis. Because of this, efforts to conserve amphibian biodiversity are urgent and have been given increasing importance. However, studies investigating the effectiveness of agroforestry systems, a commonly used agricultural method in which trees and other elements of forests are retained on land used for agriculture, for amphibian conservation are uncommon. As a result, the capacity of agroforests to serve as a tool for amphibian conservation is unclear. To determine if agroforests can serve as a habitat for amphibians and a tool for their conservation, this …

American public lands provide significant outdoor recreational opportunities that enhance an individual's physical and mental well-being. Hiking is an example of a highly accessible and affordable recreational activity that is popular and easy for people to engage in no matter how experienced they are. While hiking has improved the well-being of many individuals, its impacts on local ecosystems are often disregarded. For our research, we focused on the impacts that hikers deviating off-trail may have on a local ecosystem in Michaux State Forest in Southern Pennsylvania. Through partnering with the foresters at Michaux State Forest and using AllTrails data, we …

Breeding Polyploid Populus: Progress And Perspective, Xiangyang Kang, Hairong Wei

Michigan Tech Publications, Part 1

Populus is a genus of 25−30 species of deciduous flowering plants in the family Salicaceae, which are primarily planted in short-rotation planations for producing timber, pulpwood, wooden products as well as bioenergy feedstock; they are also widely planted in agricultural fields and along roadsides as shelter forest belts for windbreak, decoration, and reduction of pollutants and noise. Moreover, their fast-growth and good adaptation to marginal lands enable them to provide some critical ecosystem services at various phytoremediation sites for land restoration and reclaimation. Thanks to their important roles, breeding for fast growing poplar trees has been one of the most …
