Nadaka 2023 Management Plan, Andrea Hurzeler
Nadaka 2023 Management Plan, Andrea Hurzeler
Environmental Science and Management Professional Master's Project Reports
Nadaka 2023 is a management plan written for Nadaka Nature Park that aims to assess current conditions, define desired future conditions, and make recommendations to achieve those desired future conditions. Nadaka Nature Park is a publically owned nature area and park space located in the Wilkes East Neighborhood and bordering the Rockwood Neighborhood of Gresham, Oregon. Originally owned by the Camp Fire Organization, Nadaka was purchased in 1995 by the City of Gresham and opened to the public in 2001. Making up Nadaka is a 10 acre nature area and a 2 acre park space. The nature area consists of …
Long-Term Managed Flooding To Control Invasive Phalaris Arundinacea L. And Help Restore Native Vegetation In An Urban Palustrine Wetlands Ecosystem, Robert P. Lascheck
Long-Term Managed Flooding To Control Invasive Phalaris Arundinacea L. And Help Restore Native Vegetation In An Urban Palustrine Wetlands Ecosystem, Robert P. Lascheck
Environmental Science and Management Professional Master's Project Reports
We sought to determine the effects of 13 years of hydrologic management on the wetland plant community in Smith and Bybee Wetlands Natural Area (SBW), an 809 ha palustrine wetland complex in north Portland, Oregon. Previous management efforts resulted in an altered hydrologic regime; historically high water levels in spring and low water levels in fall were replaced by persistent water levels with minimal annual variations. A water control structure was installed in 2003 to better approximate historic seasonal hydrologic changes to reduce invasive Phalaris arundinacea (reed canarygrass) cover and promote native wetland vegetation growth. Vegetation monitoring has been carried …
Assessing Effort Shifts And Familial Succession In Oregon’S Nearshore Fisheries, Bryn Ellen Hudson
Assessing Effort Shifts And Familial Succession In Oregon’S Nearshore Fisheries, Bryn Ellen Hudson
Environmental Science and Management Professional Master's Project Reports
Since the industrial revolution, natural resource systems have rapidly modernized and globalized. Commercial fishing industries have expanded and optimized resource extraction but have often times exceeded sustainable levels of harvest. In the Pacific Northwestern United States, the commercial fishing industry is one of particular economic and cultural importance. Due to reduced yield of many native fish stocks, marine reserves have been implemented in Oregon’s nearshore waters in an effort to conserve biodiversity. While spatial closures of marine reserves seek to preserve and stabilize Oregon’s ocean ecosystems, adverse socioeconomic implications are inevitably created when profitable waters are set aside. A main …
Effects Of Variable Density Thinning On Spatial Patterns Of Overstory Trees In Mt. Hood National Forest, Emma Huston
Effects Of Variable Density Thinning On Spatial Patterns Of Overstory Trees In Mt. Hood National Forest, Emma Huston
Environmental Science and Management Professional Master's Project Reports
Variable density thinning (VDT) is a method of restoration thinning that attempts to increase ecosystem resilience and spatial heterogeneity in forest stands to more closely resemble mosaic-like patterns characteristic of late-successional forests, which consist of clusters of multiple trees, individual trees, and gaps. This study examines the spatial patterning of overstory trees resulting from VDT of conifer forests in Mt. Hood National Forest in the western Cascade Mountains and compares these patterns with reference conditions. Stem maps were created from field surveys of study plots within one mature stand and six thinned stands designated as Late-Successional Reserve (LSR) with varying …
