Beyond wildlife corridors: Investigating and evaluating other urban wildlife enhancement projects

Over the course of the summer, I shall be analysing various urban wildlife enhancement practices taking place in the 7 Core Cities of England. Determining if these projects have been successful overall will be based on a set list of quantitative and qualitative ecological performance indicators. To obtain qualitative data or information not readily available through public sources, I will interview personnel who have/had key roles in wildlife enhancement projects in their respective Core Cities. An additional qualitative survey will be sent out to various “green space” and nature organizations to find out what projects they have been involved in and which ones have been successful at functioning as they were intended to. The research questions I will try to answer are:

Why are wildlife corridors often the default urban wildlife enhancement policy of choice?

There hasn’t been significant data collection, experiments or academic evaluations of urban wildlife corridors to justify why they are the popular choice of urban wildlife enhancement projects. What about other methods? What is in use in the core cities? Is it working? What has been the most successful?

How can corridors and other methods of wildlife enhancement in urban areas be measured to determine overall success?

Background research and literature reviews will aid in designing a performance indicator model that will be used to summarise information gathered through the interviews. There will be both a quantitative and qualitative section, with indicators to be determined as my research progresses.
Ever since I can remember, I have always had a strong passion to explore and understand the natural world. Summers spent camping in the Canadian wilderness and years of Girl Guides were just some of the many activities I did growing up that helped me to appreciate, respect and responsibly interact with the environment. After my undergrad, I worked for a year in a National Park in the USA as an environmental educator and spent my days leading school groups through different ecosystems and teaching them how to be informed stewards to the natural world. When I read about this partnership topic dealing with biodiversity and urban wildlife enhancement projects for Bristol, I knew I could easily translate my interests in the conservation of wild spaces into an interest in protecting and enhancing urban green spaces.

The organisation I am working with is the Greater Bedminster Community Partnership, a group made up of local councillors, voluntary and community organisations, private businesses and public agencies within the Bristol wards of Southville and Bedminster. Their goals consist of improving and enhancing the quality of life for Bristol residents and community members in these areas. Members of this organization have been involved with local biodiversity counts and studies of local green spaces and have found that these two wards of Bristol are at the bottom in regards to wildlife biodiversity. The organization would like me to assess the impact of different wildlife enhancement practices and identify applicable practices that can be used in the BS3 area to enhance urban wildlife populations. I hope to use the results of my dissertation to present to the organization an assessment of different urban wildlife enhancement practices currently implemented in the UK and make suggestions on which practices would work best for their area.

Converting probabilities between time-intervals

This is the first in an irregular sequence of snippets about some of the slightly more technical aspects of uncertainty and risk assessment. If you have a slightly more technical question, then please email me and I will try to answer it with a snippet. Suppose that an event has a probability of 0.015 (or 1.5%) of happening at least once in the next five years. Then the probability of the event happening at least once in the next year is 0.015 / 5 = 0.003 (or 0.3%), and the probability of it happening at least once in the next 20 years is 0.015 * 4 = 0.06 (or 6%). Here is the rule for scaling probabilities to different time intervals: if both probabilities (the original one and the new one) are no larger than 0.1 (or 10%), then simply multiply the original probability by the ratio of the new time-interval to the original time-interval, to find the new probability. This rule is an approximation which breaks down if either of the probabilities is greater than 0.1. For example

1-in-200 year events

You often read or hear references to the ‘1-in-200 year event’, or ‘200-year event’, or ‘event with a return period of 200 years’. Other popular horizons are 1-in-30 years and 1-in-10,000 years. This term applies to hazards which can occur over a range of magnitudes, like volcanic eruptions, earthquakes, tsunamis, space weather, and various hydro-meteorological hazards like floods, storms, hot or cold spells, and droughts. ‘1-in-200 years’ refers to a particular magnitude. In floods this might be represented as a contour on a map, showing an area that is inundated. If this contour is labelled as ‘1-in-200 years’ this means that the current rate of floods at least as large as this is 1/200 /yr, or 0.005 /yr. So if your house is inside the contour, there is currently a 0.005 (0.5%) chance of being flooded in the next year, and a 0.025 (2.5%) chance of being flooded in the next five years. The general definition is this: ‘1-in-200 year magnitude is x’ = ‘the current rate for eve

Coconuts and climate change

Before pursuing an MSc in Climate Change Science and Policy at the University of Bristol, I completed my undergraduate studies in Environmental Science at the University of Colombo, Sri Lanka. During my final year I carried out a research project that explored the impact of extreme weather events on coconut productivity across the three climatic zones of Sri Lanka. A few months ago, I managed to get a paper published and I thought it would be a good idea to share my findings on this platform. Climate change and crop productivity There has been a growing concern about the impact of extreme weather events on crop production across the globe, Sri Lanka being no exception. Coconut is becoming a rare commodity in the country, due to several reasons including the changing climate. The price hike in coconuts over the last few years is a good indication of how climate change is affecting coconut productivity across the country. Most coconut trees are no longer bearing fruits and thos
