The document summarizes a study conducted by the Delta Farmland & Wildlife Trust on the effects of mowing grassland set-asides (GSA) on wildlife in agricultural areas in Delta, BC. The study compared mown and unmown GSA plots measuring vegetation cover, small mammal abundance, and northern harrier behavior over multiple years. Key findings included greater vegetation cover and preference by northern harriers for unmown older GSA. The recommendations are to maintain unmown GSA that are over one year old to benefit wildlife.
This document summarizes a study on the effects of mowing grassland set-asides (GSAs) on raptor behavior in the Fraser River Delta. The study compared mown and unmown GSAs of different ages and measured vegetation cover, small mammal abundance, and northern harrier hunting behaviors. Key findings include greater vegetation cover in unmown GSAs, low small mammal abundance possibly due to population cycles, and a preference by northern harriers for hunting in unmown GSAs over 1 year old. The presentation recommends maintaining unmown GSAs and continuing long-term research.

This document discusses strategies for eradicating invasive wetland plants at a large catchment scale. It focuses on the importance of partnership working between landowners, managers, and river champions to identify plant locations, build trust, coordinate removal efforts from upstream to downstream, and develop long-term relationships and sustained contact to successfully remove invasive plants over a large area on a long-term basis. The key is getting everyone involved to work together and maintain cooperation.
This presentation was given at the Peel Harvey Biosecurity Group's Fox Control Workshop held in Harvey. Presentation was given by Dr Peter Adams from the Department of Primary Resources and Regional Development.
This document is an undergraduate thesis that explores using thermochromic liquid crystals (TLCs) applied to thin filaments to measure changing air temperatures. It presents three experiments: 1) Vacuum oven calibration to create a temperature-color relationship for TLCs on filaments, 2) Repeat calibration with a new test piece design, 3) Measuring the TLCs' reaction time to temperature changes. The results provide methods for measuring full fluid temperature profiles in a wind tunnel test section with a standard camera, avoiding limitations of traditional point sensors. This research could improve boundary condition accuracy in aerodynamic experiments.
This document provides background information on spinal cord injuries and wheelchair back supports. It discusses that there are approximately 12,000 new spinal cord injury cases per year in the US, resulting in varying levels of paralysis depending on the location of injury. Current wheelchair backs are either expensive and highly customizable or cheap and rigid. The goal of this project is to create an adjustable back that is easier to customize than expensive models but still offers high customizability, and can adjust nearly instantly without tools at a lower price. The document reviews spinal cord and sitting anatomy, and how wheelchair backs must provide proper lumbar support to prevent spinal issues from prolonged sitting.
Snagov is a commune located 40 km north of Bucharest, Romania composed of five villages with a population of 6,041 that is 99.2% ethnic Romanian. Snagov is known as a popular holiday resort located on the shores of Snagov Lake, and archaeologists have found evidence of human inhabitation since 400 BC. The Snagov Monastery, founded in the late 14th century on an islet in Snagov Lake, is one of the most notable sites along with Snagov Lake, Snagov Forest, and Siliştea Snagovului church. Communist dictator Nicolae Ceauşescu used Snagov as a vacation retreat.
This document summarizes an undergraduate research project using thermochromic liquid crystal (TLC) technology to measure air temperature changes in a blowdown wind tunnel. The student designed TLC-coated filaments, calibrated their color changes to temperature in a vacuum oven, and measured the filaments' reaction time. Results showed a clear relationship between temperature and hue, with a reaction time of 1.49 seconds for heating and 3.68 seconds for cooling. Future work could improve the calibration and test the filaments in the wind tunnel.

Agriculture is a necessity and Delta BC has some of the most fertile soil in ALL of Canada, not only does this contribute significantly to our provincial GDP – this valuable resource feeds our growing population however the Delta is also very important environmentally
The increasing human demand encroaching on wildlife habitat – is causing loss and degradation of critical niches which negatively impacts the environment by weakening the ecosystem
The Lower Fraser Delta is an estuary which supports a diverse assemblage of wildlife – our study site is also located within this Important Bird Area (Boundary Bay–Roberts Bank–Sturgeon Bank Important Bird Area )
Reifel Migratory Bird Sanctuary, DU, The Nature Trust – Agricultural Land Reserve (focus on food production)
This conflict of interest has stirred debate for decades – but DF&WT found a resolution and is a leader is uniting farming with wildlife conservation – through six programs aimed at enhancing farming viability while providing wildlife conservation
Today we will focus on the DF&WT GLSA program – which offers long-term land management – by providing farmers cost sharing benefits – newly established GLSA are specially seeded and fields are allowed to be fallowed for four years – This increases habitat and the vegetative diversity promotes biodiversity
So, lets look into how to best manage these GLSA
With 200ha of GLSA – DF&WT wanted to make sure they were making the most of their resources –it is important to know how best to manage the GLSA – How does the establishment of a new GLSA impact wildlife? What are the impacts of mowing? Our research project looked into these factors by comparing mown vs. unmown GLSA on vegetation, small mammals and raptor behaviour
Within this newly established GLSA we have six quadrants – each are 82m x 82m – 3 are mown while 3 are left unmown - at t
Sampled from Oct to March (x4)
5 cover classes (0-1% = 1; 75-100% = 5)
Mark re-capture – recorded tag and location (mown vs unmown) collected biological data including weight and sex – However, our trapping permit did not arrive until mid Februrary, compared to early October in previous years
THIS ANIMATION NEEDS HELP!! Please… the pic underneath is too quick…
I don’t like the order of these……. Its makes more sense to talk about Oct Clover first (it should be to the first on the left)
It’s a little easier to see with photographs… but you maybe wondering, why this is important……. Look at the difference between our newly established GLSA in March, how look at a four-year old GLSA taken only days apart – This goes to show how time influence vegetative structure – a critical factor on small mammal abundance MAKE IMAGES BIGGER
Our low abundance has similar finding by other researches trapping during the same study period also in Delta – where after leaving traps out over three days only caught three TV – very low!! - Although there was clear evidence of use (this little fellow indicates that! Our trapping effort was limited by time)
Although NOHA exhibited a preference to unmown habitat (a re-occurring pattern and well referenced in other literature as well) What was unique to our study was the decline in NOHA observations from all previous years. GET SAMPLE AMOUNTS FROM PREVIOUS PAPERS
Low Cyclic Abundance - Occurs 3-5 years - Emphasised by GLSA - Coincides with Northern Harrier low abundance
Mention 200ha of GLSA – SET Backgroud with GLSA pic from report
Due to increasing demand for agri production in the area, orgs like DFWT are true leaders – by sampling for veg composition change, vole abundance and raptor behavior preference – we are building onto a multiple year data set which can be used by the Trust to make long-term management decisions -
Today’s environment faces increasing demands which increases with the growing population – The Lower Mainland is no exception, our city centers and urbanization are expanding – and with it increased development of neighboring lands
