  • Golan Hello all and welcome to this talk by Raza and myself. In this talk we will be covering the first 5 stages of the first phase of the BS8555 EMS. The last two stages are ongoing which is why they are not covered although we will touch on this in regards to our project. Also, we will be discussing how we are looking to take this project forward and what are the next steps for us in the final stages of this project. We will be alternating which slides we are presenting. I will now pass you on to Raza to talk about Stage 1 of the first phase of BS8555.
  • Raza Give some history of the park We approached Tony Day who is an assistant warden at the park They were keen as they need to get rid of the invasive species
  • Goldfish were introduced into this park in 2004, which Raza will tell you more about later. Goldfish are r-strategist species which means they are invasive species. Much research has been done on goldfish, in one paper by Copp et al. In 2005 they found that goldfish are invasive keystone species which means they can change the balance of an ecosystem they are in. Also, they reach sexual maturity very quickly, and they outcompete other generalist fist species. Goldfish are a problem in Greenwich Ecology Park because they breed with native fish species (like the roach) and form hybrid offspring which affects the gene pool. Also, they are vectors for disease – for example, people drop food into the water for the fish. This invites rats to eat the food too. When the rats come they urinate in the water which can cause leptosorosis (septic skin and weakened immune system) in people. Also, when people drop food it affects the nutrients in the water causing an increase in nutrient levels which leads to an alternative equilibrium. This means that there are algal blooms, and invertebrates and flora are affected. Also, the benthos is disturbed which affects invertebrate spawn. Furthermore, the introduction of goldfish has led to an introduction of fisherman who ensure there are always goldfish by providing food (which affects the nutrient levels) and dump more goldfish in the lake.
  • The park provided us with data of their surveys on odonates (like ffasfasfasd). The park holds surveys every year for 6 months between the months of From the data they have provided, we have noticed that since the introduction of goldfish in 2004 there has been a decrease in the Odonata population. The park was only able to give us information up to 2005, but from their most recent surveys they have noticed a decrease in Odonata and smaller population sizes. Now I will pass onto Raza to talk about action they have taken so far in the Park.
  • Raza
  • Having done research on the problems facing the Park and after having discussions with Tony Day we have noticed that the 3 main points of our policy are: defishing, education and incentives. Incentives – researchers like Lorenzoi et al in 2007 have researched about how if you give fishermen incentives then they are less likely to dump fish in the lake and give fish eggs to the Park Wardens to dispose of. Education – educating the local residents/visitors/schools about the problem Defishing – using a variety of methods to get rid of the fish (e.g. Fyke nets, seine nets, gill nets, electrofishing)
  • Raza Tom Cousins Process written consent Cryptic location www.efishbusiness.co.uk
  • For our project there was no need to develop more indicators as the park already has the only two viable ways of indicating changes in the park already. Odonata survey which is already being done as mentioned earlier Observing goldfish population which is done by simple observations by eye. This is a superficial way of observation but it is the only means available to the Park Wardens because they don’t have a fishing licence.
