Transcript

  • 1. Created by: Sam Ikua and Forest Dyer Grassland
  • 2. What are grasslands?
    • The scientific definition would be: a region in which the climate is dry for long periods of the summer, and freezes in the winter. grasslands are characterized by grasses and other erect herbs, usually without trees or shrubs.
    • Our definition for it would be a part of land that is covered by a whole bunch of grass with lots of bugs and animals in it.
  • 3. Some info on grasslands.
    • There are many different types of grasslands for example savannas, pampas, campos, plains, steppes, prairies and veldts.
    • These different types of grasslands contain different types of plants and animals.
    • For example the Panicled Aster , Goldenrod, and Blazingstar are all located in the wet prairies.
  • 4. Different types of plants
    • There are a wide variety of plants in the grasslands.
    • Here are some more example of plants in the savanna.
    • Kangaroo paws- “ What really catches the eye is the plants green unscented flowers that can grow up to 10 centimeters long. The green furry flowers are attached to the sturdy red stem.”
    • Elephant grass- Elephant grass is a tall grass that originally came from Africa in 1913. It grows in dense clumps of up to 10 feet tall. In the savannas of Africa it grows along lake beds and rivers where the soil is rich.
  • 5. Climate
    • The climate for  grasslands is mainly dry.  Rain fall usually does not go over 100 cm per year, and the least amount near 20 cm per year.  Also, grasslands tend to be in temperate  to tropical areas, often with cold winters and hot summers.
    • In the winter, grassland temperatures can be as low as -40° F, and in the summer it can be as high 70° F. There are two real seasons: a growing season and a inactive season. The growing season is when there is no frost and plants can grow. During the inactive (not growing) season nothing can grow because its too cold .
  • 6. Panicled Aster
    • Distinctive features- open spreading form. Dead stem leaves very curly.
    • Height: 30-120cm Habitat: Moist low areas, open or forested. Lifespan: Perennial.( means: comes back yearly)
  • 7. Continued
    • The curly dead leaves are one of the best ways to identify the flower
    • Panicled Asters have many small prick-shaped leaves along their stems.
  • 8. Goldenrod
    • Distinctive features: Very hairy stem. Flowers thin stem. Individual flowers relatively large.
    • Habitat: woods and forest edges which are mostly grasslands.
    • Lifespan: perennial
  • 9. Continued
    • One way to identify a hairy Goldenrod is by looking at the stem and seeing if there is tiny hairs on it.
    • The flowers usually bud in august.
    • The flowers are usually large and spread out.
    • The leaves are also hairy as well as the stem.
  • 10. Blazing star
    • Distinctive features- The leaves are alternate. The stem leaves are very slender and all are entire. The leaves seem to spiral around the stem and are often marked with dots or resin .
    • Habitat- various (meaning that it can be found in many different areas in the grasslands)
    • Lifespan- perennial
  • 11. Continued
    • The blazing star is a native North American species and is often seen in people gardens. Identifying the species can be tricky. There are at least a dozen species of Liatris (scientific name for the blazing star species) in the southeast and some northern species enter parts of our range.
    • The only real way to identify the flower would be to count how many petals are on it or the shape of the pappus.
  • 12. Continued…
    • Here are some examples of the blazing star
  • 13. The End
