Post-Project Appraisal in Social Relationships between the Ecological Restoration Project on Stoney Creek and the Surrounding Community, Burnaby, British Columbia

Peer reviewed:

Date created:

Abstract: 

Scientific studies upon ecological restoration projects and their relation to nearby environments such as soil quality, invasive species, beetles living habitat have been studied extensively by varies research groups. However, researchers seem to have neglected the social relation between residence and the ecological restoration project. Knowledge on public attitudes and perceptions toward ecological restoration projects is essential in exploring the public’s degree of supportiveness and in creating a sustainable restoration project. Using Stoney Creek in Burnaby, British Columbia as a case study, this study searches for the relationship between community members attitudes and knowledge towards ecological restoration by examining the correlation of the resident’s place attachment, length of residency, and their willingness to engage. The study has found a direct relation between public’s interest in ecological restoration and their willingness to engage. The public’s willingness to engage also has a relation to their attachment to the creek. The public’s awareness and knowledge is related to the residents’ attachment to Stoney Creek and the duration of residency in the area. Proximity to the creek, however, does not seem to have a correlation to the public’s perception of Stoney Creek’s ecological restoration project.

Post Project Appraisal for Stoney Creek Off-channel Habitat Pond: Hydrological Suitability for Juvenile Salmonids

Peer reviewed:

Date created:

Abstract: 

Habitat restoration is an important process in protecting the iconic salmon in British Columbia. Specific criteria must be met in order to provide a successful salmon habitat. Water quality within the off-channel pond at Stoney Creek was analyzed with data collected from six essential parameters: turbidity, velocity, depth, as well as copper, nitrogen and iron. These were tested over two days under different weather conditions. Turbidity, velocity, iron and nitrates presented preferable conditions while depth could potentially be improved for the salmon’s wellbeing. Copper testing was determined to be inconclusive. We conclude that the Stoney Creek off-channel pond is an appropriate water habitat for juvenile salmonids to rest and develop. Possible future management strategies include increasing the overall depth, continued monitoring by the Stoney Creek Environment Committee, future copper testing with more sensitive equipment after a first flush event, and an increase in public outreach and education.

Ground Beetle (Coleoptera: Carabidea) Community Structure as an Indication of Disturbance in Stoney Creek, Burnaby, BC

Peer reviewed:

Date created:

Abstract: 

To investigate the impact of constructing an off-channel pond in Stoney Creek, Burnaby, BC to ground dwelling arthropods, carabid beetles were sampled at three sites: the pond site, the adjacent site, and the upstream site. The pond site was the area in which the artificial pond was constructed to create spawning habitat for salmon, and it was the most disturbed site. The other two sites were relatively undisturbed and were used as a comparison. Species observed in all sites were forest generalists consisting of both native and invasive species. This indicates that all sites have experienced recent disturbance since significant time has not passed to allow specialists to become re-established. Species evenness, however, was calculated to be lowest in the pond site, greatest in the upstream site, and intermediate in the adjacent site. This is due to the different characteristics of each site; the pond site had an open canopy as most of its vegetation had been removed, the upstream site was dominated by tall trees and is characteristic of a natural riparian zone in BC, and the adjacent site had a relatively open canopy as much of the understory was dominated by Hedera helix (English ivy) and Rubus ameniacus (Himilayan blackberry). Unfortunately, statistical analysis could not be performed since a small number of individuals were caught at each site; the impact of the off-channel pond construction is inconclusive. Future studies can, however, use this study as a comparison and further elaborate on these results.

Assessment of Past and Present Sediment Quality of Stoney Creek in Burnaby, British Columbia

Peer reviewed: 
No, item is not peer reviewed.
Date created: 
2013-04
Abstract: 

In analyzing the sediment and water quality of the Stoney Creek habitat, four key aspects were investigated: lithology, sediment/water quality, salmon spawning/incubation, and particle size distribution. The lithology found the streambed sediment layer is 3 cm in depth (over bedrock) and consists mainly of sand and some coarser material including gravels, cobbles, and boulders. The sediment of the offchannel pond is mainly mud (fine material) with a moderate amount of sand and a very small percentage of coarser material including gravels and organic matter (leaf detritus and woody debris). Chemical analysis concluded a significant concentration of iron in the pond environment, with potential for adverse effects to salmon offspring. This report further aims to assess the influences of fine sediment on the quality of salmon spawning habitat and incubation success rate. Permeability of spawning gravels and dissolved oxygen concentrations are measured to see if they support the incubation and growth of salmon eggs. Particle size distributions are found significantly different between upstream pool and pond side. And the difference of particle size distributions can influence salmon production in the off-channel site.

An Assessment of the Restoration of Shade in the Stoney Creek Habitat Improvement Project

Peer reviewed: 
No, item is not peer reviewed.
Date created:

Abstract: 

 The Stoney Creek restoration project was expected to have a large impact on the surrounding riparian vegetation. Canopy shade is an important factor affecting salmonids through regulation of water temperature. In seven restored and three unrestored sites, fish-eye photography was used to measure canopy openness as an indirect measurement of shade, and to determine if this was similar between restored and unrestored areas. There were several limitations of this analysis, however, including the fact that deciduous trees did not have all their foliage at the time of year this project was conducted. A clinometer was used to measure the heights of the tallest trees surrounding the sites to see which sites would have more cover from the sun. There were several limitations with the clinometer use, as well, including the weather. Several of the restored sites had similar levels of canopy openness as unrestored sites, but several had lower levels. Tree heights were found to be fairly similar across all sites. We conclude that it appears as though several sites were not sufficiently restored to their pre-restoration project levels, which may be due to an insufficient amount of growing time since replanting occurred, and this may have important impacts on salmonids.

An Assessment of Stream Health Through Use of Macroinvertebrates as Bio-­‐Indicators

Peer reviewed: 
No, item is not peer reviewed.
Date created: 
2013-04-22
Abstract: 

The Stoney Creek Off--‐Channel Habitat Improvement Project aimed to restore a stream section in Burnaby, BC. The species assemblages of macroinvertebrate bioindicators were analyzed with reference to stream health of the restored ecosystem. Using a region specific B-IBI, species assemblages were characterized according to their tolerance to pollution. Samples where collected from a previously restored upstream site and recently restored downstream site and individually from riffle and pool zones within each site. Frequency distributions and relative abundances were used to measure actual and relative representation of categories. Overall, pollution tolerant species showed the highest representation over both sites when compared to pollution intolerant and somewhat tolerant species. Riffles exhibited a higher presence of pollution intolerant species then pools. These results indicate relatively low stream quality. Results of the WQI did not support the stream quality data provided by macroinvertebrates. Further study needs to be undertaken to involve baseline data and address additional determinants for species assemblages.

Error Concealment for 5/3 Motion Compensated Temporal Filtering with Lifting

Abstract: 

5/3 Motion Compensated Temporal Filtering (MCTF) is a tool for highly scalable video coding which has been recently studied by many researchers. This thesis presents several error concealment algorithms for 5/3 MCTF with lifting, which can be used to improve the quality of compressed video damaged by packet losses. In MCTF video, the low frequency subband frame, abbreviated as L-frame, contains most of the signal energy in any given Group-of-Pictures (GOP). We assume that one of these L-frames is lost. The proposed error concealment algorithms use the available data to reconstruct the missing L-frame. The simplest error concealment method considered in the thesis is Zero Motion Error Concealment. This method simply assumes zero motion through the damaged GOP, and averages the neighboring L-frames to reconstruct the missing L-frame. Another method called Motion Concatenation finds temporal pathways through the damaged GOP by connecting motion vectors available at the decoder, and copies the corresponding pixel values from the neighboring L-frames to the missing L-frame. Finally, Motion Re-estimation uses motion estimator at the decoder to find a motion vectors between two neighboring L-frames of the missing L-frame, and synthesizes the missing L-frame halfway between its neighboring L-frames. The overall error concealment system combines these three methods to maximize visual performance, as well as the Peak Signal-to-Noise-Ratio (PSNR).

Locating Pinocchio Before 1940: The Italian Allegory Gone Awry in English Translation

Author: 
Peer reviewed:

Date created:

Abstract: 

If we consider that the very basic element of a children’s story is its appeal to world literature, then a text like Pinocchio exists for and in translation. However, how the extra linguistic material functions and how it is dealt with in translation is the concern of this paper. Because Pinocchio has become an item of world literature by way of its translations, the allegory created by Carlo Collodi about the reality of the Italian situation post-Unification has been lost in English translation and replaced in the target culture by a pedagogical set of moral codes in order to replenish the story’s meaning. Consequently, the value of reading texts comparatively manifests in reconciling what is lost with what is gained. Reading the English translations in light of the original Italian story reveals respective intricacies of both cultures and validates the process of translation as a privileged mediator.
