General Info:

The name of this ecosystem is the Tropical Savanna. It is receiving more seasonal rainfall then desserts but less than tropical dry forests. The savannas are spotted with isolated trees and small groves of trees and shrubs. Compact soils, fairly frequent fires, and the action of large animals prevent some savanna  areas from turning into a dry forest. The tropical savanna is home to the  endangered Golden-Cheeked Warbler.

Factors:

3 abiotic factors are:

  1. Warm temperature

  2. Frequent fires set by lightning

  3. Seasonal rainfall


3 biotic factors are:

  1. Vegetation that is dominated by different types of grass

  2. The animals tend to be bigger than in the jungle

  3. Some thorny trees known as acacias

Human interaction



  1. Humans cause desertification, where they raise cattle and the cattle eat the grass causing it to wear away and stop the grass from growing.

  2. Sometimes humans cause fires which can burn down homes of organism or open seeds for the grass



interesting facts


  1. It is not suitable for farming

  2. If one animal was removed from the savanna the entire ecosystem would be altered

  3. It is mostly made up of grass but there are some trees

  4. During the dry season some animals go so long without water they barely make it to the wet season



food cycle


golden-cheeked warbler behavior


The warbler will only nest in Texas primarily in Juniper trees. Male warblers win the attention of female warblers through their “chip” sounds which they also make as a warning call. Female warblers are more shy and go more unnoticed compared to the always-singing males. The male warblers are found either singing or searching for food. The females take the responsibility of nest building as well as keeping the eggs incubated.



Golden-cheeked warbler characteristics

Warblers eat insects and spiders found on the leaves and bark of oaks. If a golden-cheeked warbler lives in the wild they have an average lifespan of 48 months. A golden-cheeked warbler will only lay its eggs in the tropical savanna of Texas.
