The importance of conserving dipterocarp species
Introduction Dipterocarp term is derived from Greek word which means two-winged fruit (di = two, pteron = wing and karpos = fruit). Dipterocarp are tropical plant so the distribution of dipterocarp tree species mostly located in Borneo Island, Peninsular Malaysia, Southern Thai, Indonesia, Indochina and some places in India and also Sri Lanka. The most diverse dipterocarp can be find on the island of Borneo with 300 species approximately. Dipterocarp divided into 17 genera and there several genera that popular to dipterocarp for example Shorea, Hopea, Dipterocarp and the Vatica. The dipterocarp tree can be taller and usually have length of 40 to 70 meters tall. The tallest tropical tree in the

Each other have their own importance for example, HDF is very important for water catchment in ecological process. Mostly water that became the rivers originate from this area. During rain, HDF help this ecological process by trap the rain and then channel it into the river. HDF also acting as natural reservoirs and natural filter system that not only store the water but also help cleaned the water from sediments and silts. If no HDF, first landslide and second thing is the river full with silts and sediments. Landslide occur when no more rooting system from the trees to help support and clutch the composition of soils, make soils easily broke. The leaves of HDF can prevents rain contact directly with the soil and slow down the speed of raindrops. If no leaves of HDF in this area, the soils are easily weaken and more sediment carried by the raindrops. Sediments and silts carried by the water surface runoff and accumulate in the rivers. This make the river water turn cloudy and not suitable for river ecosystem and domestic used by human because the sediment suspended in the
Through her masterful usage of color and lighting, painter Alexis Rockman seeks to display the overwhelming beauty of the natural world and its inhabitants in her painting Kapok Tree. With a color scheme of bright colors that pops out and grab the attention of the viewer and an emphasis on lighting that divides the painting into two separate scenes, Rockman’s Kapok Tree delivers its timeless message with ease.

How does the vegetation surface type affect the amount of runoff? Speculate why this happens.
The Japanese maple trees were subjects for much poetry and art in seventh century Japan. However, both world wars took their toll on the many different collections of these trees, and they were often used as firewood. By the end of the 1940s, many cultivars had disappeared. However, in the 1960s there was a return of interest and since then over 320 varieties of the Japanese maple have been developed from the native trees that were left.
The weather in this novel controls their crops and the river flow; which controls their food and water supply. They depend on adequate rainfall to help their crops to grow and for the river to be full. They also depend on the sun to warm things up and make the crops grow. However, if there is too much rain or too much sun it can cause many problems, such as a drought or a flood. These things are significant in this novel, because t...
Water that has changed throughout the hydrologic process travels from the irrigation treatment and enters into the aquifers. First...
Introduction: Drought affects our lives in many different ways because water is such an important part of so many of our activities. We need water to live, and animals and plants do too. We need water to grow the food we eat. We also use water for many different things in our lives, like washing dishes, cooking, bathing, and swimming or river rafting, so water is very important for us to survive.
Acid rain either falls directly onto the lake or enters through the catchment (Buchdahl). A very small percentage enters directly so the majority enters through the catchment. The alkaline rich catchments can neutralize the rain. However, not all types of bedrock have the same capability of neu...
Mainly, impoundment hydropower, the creation of large reservoirs, covers all of these gains. The construction of dams has many perks to society. The opportunity for many outdoor sports and activities presents itself. For example, reservoir lakes bring boating, swimming, fishing, and more. Impoundment hydropower also allows for greater control over potential emergencies, like floods and water shortages (dams can be closed to save water). In rural areas, basins provide ready-access water for farmers to use for irrigation of crops. The pros of hydropower go far beyond climate
When a dam is built a reservoir collects behind it, which also collects rainwater. The reservoir allows us to control the amount of water that flows through the dam and lets us still have a steady flow of water, even during years with less rainfall. The dam itself has spillways to control the amount of water leaving the dam. One major problem with dams is the affect they have on migrating fish traveling up and down the rivers. Many dams have special fish ladders to allow the fish to pass through (Today, 2001).
Trees help complete the water cycle by returning water vapour back in the atmosphere.

Trees are usually considered as bland, unusual objects that are usually taken for granted; however, I believe there is more to a tree that meets the eye. They supply oxygen and shade. During the holidays, trees are able to spread holiday cheer by wearing holiday decorations. Through providing, they are always beneficial to the needs of others. Rather than having striking beauty like a flower, trees have are grounded and possess a gentle beauty; they are adapted wildflowers to their environment. In fact, if I had to compare myself to an inanimate object, I would choose a tree. A tree has many characteristics in common with me. Characteristics like relying on our roots, strength and observation, and helping others and leaving behind a powerful legacy are a few of the traits we share. All of which I believe are admirable qualities to possess.
Trees are one of the most important parts of the biosphere. They provide oxygen, which is one of the largest producers of life. Humans live and strive off of oxygen every second of their lives. Not just humans need oxygen to survive and thrive on Earth, but animals, and other creatures on the planet do as well. Trees are a huge part of all life and if they were gone, there would consequently be no form of life. Not only do trees create all forms of life, but they create beautiful surroundings for an area and create a comfortable and shady environment for all surrounding life. Even though trees seem to be everywhere you look, the planet is losing billions upon billions of them a year. Anywhere from three billion to six billion trees are lost every year, ("How Many Trees Are Cut Down Every Year? Rainforest Action Network Blog. N.p., n.d. Web. 10 Apr. 2014”). With this fact in thought, it shows that planting one tree can create a bigger difference than you realize.
Urbanization: Soil is considered as water reservoir. Urbanization acts in creating amount of impermeable surface due to construction of buildings, roads, drainage, sewage, flood relief channel etc. It reduces the amount of infiltration and percolation. Water tends to experiment the runoff process rather than infiltration. This contributes to increase in
