These arid and semi-arid regions have shown increases in invasive species such as cheatgrass, which grows very quickly in dry climates, and is highly flammable.
This has led to an increase in fire frequency and distribution across much of the western United States and Canada. Other effects of decreased precipitation can be seen in other areas worldwide. A lack of water can mean no breeding grounds for waterfowl, or dryer conditions can allow predators access to areas they otherwise would not hunt in such as has been observed in African savannahs. In this way, climate changes can greatly disrupt biomes, and offset the delicate balance of a given ecosystem.
In addition to climate changes, grasslands are also one of the most popular areas for human development. This is mainly due to the fact that the flat land is much easier to clear than a forested area. Because of this, grasslands are often cleared and repurposed for agricultural uses. This has happened in abundance in prairie areas, such as in North America, where natural grasslands have been replaced with crop fields. In many areas even natural grasslands are at risk from existing agricultural systems.
Australia has an abundance of cattle farms, and many of these farms allow their cattle to roam free, eating natural grasslands. While free range farming can be much more sustainable than other options, this can still have a devastating effect on grasslands that would not naturally see such heavy traffic from grazing animals which can decimate grass populations. Zebras in a grassland in Africa. Temperate grasslands have a high density of wildflower.

The soil in these regions is particularly rich and fertile, which is why it has been so productive when converted to farmland. While the plants growing in these areas are obviously not native to the temperate grasslands, it is worth knowing what crops are most frequently grown in this region, as these are now the most common plants grown in what was once America's native temperate grassland biome.
The plants most commonly grown for agricultural purposes in this area are grains including corn, wheat, oat, rye and hay, although potatoes are also a popular crop. Whereas the temperate grasslands get about 10 to 30 inches of rain per year, the tropical grasslands receive 20 to Additionally, they don't go through a cold, dormant period but instead sometimes go through a dry, hot season when some plants go dormant.
All of this means more trees though there are still many fires, so these trees must be fire and drought resistant and taller grasses, usually between 3- and 6-feet tall, although elephant grass can grow as tall as 10 feet.
Common grasses in tropical grasslands include Bermuda grass, elephant grass, blue fescue, feather grass, Rhodes grass, red oats grass and lemon grass. These grasses generally go dormant during the dry period and then grow rapidly during the wet season. While there may be more trees in the tropical grasslands, they need to be specially adapted to this region that has porous, unfertile soil, many droughts and frequent fires. There are also more large and diverse animals in these regions, so trees need to protect themselves from grazers.
