The pollution in the park is quite bad. So we must do something to decrease the pollution of the park. Decreasing the number of people who fish there and using more park rangers to keep watch of the people who are using the park are some ways to make the park better. The people using the park should be more cautious of what they do and not litter and pollute the water.

Dragon-boating causes the organisms in the pond to be beaten by the paddles of the people who row them. The ripples of the water might also affect the fishes that are swimming in the lake. Some people might also anyhow litter in the park and throw rubbish into the lake.

Short description of the small community we were assigned to during our trip
Our class went to Jurong Lake Park on the 27th of August. Each group was assigned to a small community. The communities are, water-edge, undergrowth, tree, bridge and rock. Our group was assigned to the bridge community. In this community, there were a lot of species and organisms living in it. They were of all shapes and sizes. This is one of the organisms near the bridge community.
This organism’s scientific name is Lycopodiaceae. This organism is a non-flowering plant and it does not produce seeds.
This organism’s scientific name is Cheiroglossa palmata (Left Hand corner). This organism is also known as dwarf staghorn, or hand tongue, which is a terrestrial, fern-like plant. These are some examples of organisms with different characteristics, shapes and sizes in the bridge community.

Name: Lumbriculus ille
Brief description: Lumbriculus illex is a fresh-water worm, the most recently described member of the genus (Timm & Rodriguez, 1994), and is known only from 3 individuals found in Komarovka stream, north of Vladivostok. In most regards, this species is probably similar to Lumbriculus variegatus, but it can be told apart from this species by its one-pointed setae (other Lumbriculus have two-pointed setae). Its closest relative is probably L. sachalinus or L. olgae. Mature Lumbriculus can also easily be told apart by a number of genital characters, but as few of the species in the genus ever become sexually mature, it is often difficult for you to know which species you are dealing with.
Classification:
Kingdom: Animalia
Phylum: Annelida
Class: Clitellata
Subclass: Oligochaeta
Order: Lumbriculida
Family: Lumbriculidae
Genus: LumbriculusSpecies: L. illex

Name: Lycopodiaceae
Brief description: The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) is a family of primitive vascular plants, including all of the core clubmosses. These plants bear spores on specialized structures at the apex of a shoot; they resemble a tiny battle club, from which the common name derives. They are non-flowering and do not produce seeds.
Classification:
Kingdom: Plantae
Division: Lycopodiophyta
Class: Lycopodiopsida
Order: Lycopodiales
Family: Lycopodiaceae

Name: Hippocastanaceae
Brief description: Hippocastanaceae is the name given to a small group of trees and shrubs, when this group is treated as a family. Its most widespread genus is Aesculus (the horse-chestnuts and buckeyes, syn. Pavia). However, the American genus Billia and the Chinese genus Handeliodendron are also sometimes included in this family. A feature of the family is the palmate compound leaves.
Classification:
Kingdom: Plantae

Name: Marine snails
Brief description: Marine snails have much greater diversity and a greater biomass. The great majority of snail species are marine. Numerous kinds can be found in fresh water and even brackish water. Many snails are herbivorous, though a few land species and many marine species are omnivores or predatory carnivores. Snails that respire using a lung belong to the group Pulmonata, while those with gills form a paraphyletic group; in other words, snails with gills are divided into a number of taxonomic groups that are not very closely related. Snails with lungs and with gills have diversified widely enough over geological time that a few species with gills can be found on land, numerous species with a lung can be found in freshwater, and a few species with a lung can be found in the sea.
Classification:
Kingdom: Animalia
Species: snails

Name: Algae
Brief description: Algae are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms. The largest and most complex marine forms are called seaweeds. They are photosynthetic, like plants, and "simple" because they lack the many distinct organs found in land plants. For that reason they are currently excluded from being considered plants.Classification:
Domain: Eukaryota

Name: Cheiroglossa palmata (Left Hand corner)
Brief description: Cheiroglossa palmata, variously known as hand fern, dwarf staghorn, or hand tongue, is a terrestrial, fern-like plant. The genus Cheiroglossa is in the family Ophioglossaceae of the order Ophioglossales, a small group of non-flowering vascular plants. The hand fern is an epiphyte, growing in old leaf bases of the Cabbage palmetto (Sabal palm). It is closely related to, and sometimes treated as a subgenus of, the genus Ophioglossum.
Classification:
Kingdom: Plantae
Division: Pteridophyta
Class: Psilotopsida
Order: Ophioglossales
Family: Ophioglossaceae
Genus: Cheiroglossa
Species: C. palmata

Name: Seed of Mucuna or Dioclea
Brief description: Some plants, such as Mucuna and Dioclea, produce buoyant seeds termed sea-beans or drift seeds because they float in rivers to the oceans and wash up on beaches.
Classification:
Kingdom: Plantae
Species: Seeds

PART A
Group's Reflection on our trip to Jurong Lake Park:
On 27th August 2009, we went to Jurong Lake Park to look at and to take pictures of the organisms there. We saw many organisms and it was very interesting to be able to see different types and different species of organisms. Although we only managed to take a few pictures as it started drizzling halfway through, we managed to see water snails, their eggs, and many small fish near the water.
We also saw a decomposing bird there, and there were many bees feeding on it. The bird could have died due to pollution or a park user might have hurt it. On our way back to school, we also saw a squashed frog on the floor. It must have been a result of human activities, for example, cars driving along that road might not have seen the frog and might have accidentally ran over it. We also saw a boat on the lake. The people on it might have been patrolling the area for litter in the water.
Jurong Lake Park:
A landscaped sanctuary called Jurong Lake Park was built around the perimeter of the lake and work was completed in January 2006. Also, a 2.8 kilometre water promenade along Jurong Lake Park would allow residents to participate in watersports.
As is the case for most other reservoirs in Singapore, fishing and swimming are currently illegal in the lake, although this may change in line with the Singapore government's liberalisation of the use of bodies of water in the republic. However, the water is noted to be green in colour during dry weather and a murky brown after a downpour, the likely result of runoff from its urban catchment area.
The lake came into prominence in 2002 when a boy fell into a drain which led to Sungei Lanchar during a thunderstorm. His lifeless body was subsequently found in the lake after a search operation two days after the incident.
