Pre-Logging Liana Cutting Reduces Liana Regeneration In Logging Gaps In The Eastern Brazilian Amazon, Jeffrey J. Gerwing, Christopher Uhl

Environmental Science and Management Faculty Publications and Presentations

The cutting of all lianas prior to logging is a reduced-impact logging technique that is predicted to reduce liana proliferation in logging gaps. This study compares liana abundance and species composition in gaps created during conventional and reduced-impact logging in a forest of the eastern Brazilian Amazon. Logging treatments were conducted in side-by-side plots. Shortly following logging, 50-m² plots were located in the approximate centers of four single treefall and four multiple treefall gaps in each logging area. Six years following logging, there were ∼40% fewer climbing lianas in reduced-impact gaps than in conventional logging gaps. In both logging …

Forest Landscape Change Detection In The Meseta PuréPecha, MichoacáN, MéXico, John Malcolm Chase

Dissertations and Theses

Social, political, economic, and environmental factors converge in developing countries to stimulate high rates of deforestation. Forest conversion reduces biodiversity, contributes to carbon loading of the atmosphere, alters the global water balance, and degrades the quality of life for rural people. Mexico is the fifth most biologically diverse country in the world and temperate and tropical forests in Mexico are rapidly disappearing with environmental and cultural repercussions for people and ecosystems.

This study examines changes in the forest landscape surrounding two communidades indigenas in Michoacan, Mexico over a 15-year period. The research area includes communal forest, pasture, and agricultural land …
