Grassland and Chaparral

  1. Grassland & Chaparral Group 3 Members: Irah Maye Singson Denise Campillanos Rigel Zumarraga Darleen Jenn Bobis Philip Tenido Objectives: • Defining the Grassland and Chaparral • Classify what is the examples of Grassland and Chaparral in the Philippines • Identifying the biotic and abiotic in the two biome • Determine their climate • Determine the Human impact and how to lessen these impact.
  2. GRASSLAND BIOME • Are large, rolling terrains of grasses, flowers and herbs. • A region where the average annual precipitation is great enough to support grasses, and in some areas a few trees • It can be found in the middle latitudes, in the interiors of continents. • The most Important plants here are grasses TWO KINDS OF GRASSLAND 1. TEMPERATE GRASSLAND: called PRAIRIES -grasses grow from roots just underground and are not killed when fires burns their leaves and stem. Because of hard underground stems and buds . 2. TROPICAL GRASSLAND: called SAVANNA - the length of the growing season is determined by how long the rainy season lasts. Also, it determined by temperature. Found in the tropics…near equator. Amount of precipitation supports tall grasses but only occasional.
  3. TEMPERATE GRASSLAND: called PRAIRIES• The prairie grasses’ success, like most other plants, is dependent on moisture. Where there is more moisture, the prairie grasses grow very tall. • Where there is less rain, the grasses are likely to be short. • Some areas are a mixture of tall and short grasses. Climate: •hot summers and cold winters. Coron Palawan Bohol Araceli Palawan Batanes
  4. Prairie soil is deep and fertile much of the land and used to grow grains such as: Corn Plantation Cagayan Valley Barley Plantation Cordillera Temperatures in the temperate grasslands vary with the seasons. In some areas winter temperatures can fall to well below 0 degrees Fahrenheit. And in summer, temperatures can reach above 90 degrees Fahrenheit. The grasses in the prairie are green in spring and turn brown in summer and fall. In other country, snow protects the plants from the cold and also provides water in spring when the snow melts.
  5. • Grasslands don’t provide much shelter for predators to hide, and they do provide an abundance of grass for food. • Most prairie animals are herbivores, however there are some carnivores and omnivores. TROPICAL GRASSLAND: CALLED SAVANNA • The Savanna is a grassland with scattered individual trees. • Climate is always found in warm or hot climates where the annual rainfall is from about 20- 50 inches per year. The largest part of savannas may receive as much as 50 inches of rain during the 6 mons of wet season, but as little as 4 inch during dry season. But, the rain does not fall even throughout the year in the savanna. There is a very rainy and very dry season. Calauit Island, Busuanga Palawan. Cebu Safari Palawan Calauit Island, Busuanga Palawan.

Acacia tree Plants Whistling Thorn With lots of long grass, the savanna is a perfect place for large grassing eating herbivores.— more than any other biome on Earth.

  7. Human impact and how to lessen these impact. Threats •Continued global warming could turn current marginal grasslands into deserts as rainfall patterns change. •Land once incompatible with row-crop agriculture, but which provided a living to ranching families and habitat for prairie wildlife, is being converted to row crops. •Development of urban areas is increasingly cutting into grassland habitat. •Drought-hardy, cold-resistant, and herbicide-tolerant varieties of soybeans, wheat, and corn allow crops to expand into native grassland. •Where only one crop is grown, pests and disease can spread easily, creating the need for potentially toxic pesticides.
  8. Solutions •Continue education efforts on how to protect the soil and prevent soil erosion. •Protect and restore wetlands, which are an important part of grassland ecology. •Rotate agricultural crops to prevent the sapping of nutrients. •Plant trees as windbreaks. •Conduct dry season burning to obtain fresh growth and to restore calcium to the soil that builds up in the dry grasses.
  9. Chaparral Biome  This biome is characterized by having both forest and grassland.  Parts of the chaparral biome exist in California, Oregon, South Africa, and Australia.  It comes from the Spanish word meaning shrub oak

  11. Abiotic Factors  Temperature ○ Typically very hot during the day and cool to cold at night.  Rainfall ○ Dry and receives only 25 to 44 cm of rain a year, predominantly in the winter rain season. Summer sees approximately 0 to 5 cm of rain and because of this droughts are commonplace.  Light ○ Similar to deserts, the Chaparral biome has a very low moisture content in the air and as such clouds rarely form. Light in the Chaparral biome is constant and bright.
  12.  Seasons  The Chaparral biome has two main seasons: a hot and dry summer season that lasts for around five months and a wet winter. The winter season is when virtually all of the biome's rainfall occurs.  Soil  The soil of the biome is typically dry and dusty, with little nutrients. The soil is vulnerable to erosion due to its fine nutrient poor nature. Below the layer of soil is typically a thin layer of clay or rock. The soil conditions make it very difficult for any vegetation to grow.
  13. Human Impacts  Tourist attractions  Development (Buildings, Factories, etc.)  Pollution  Animal Hunting  Forest fire  Kaingin
  14. Solutions  Do not live near or build homes in this area.  Do not hunt animals.  Do not cut trees
