#702: Drought

Drought is a threat to many native species and is therefore connected to natural history.

Droughts are defined differently depending on location.

From the DEFRA website.

There isn’t a single definition for drought so whilst it’s caused by a period of low rainfall, the nature, timing and impacts on people, the environment, agriculture or business will vary.

Some droughts are short and intense, caused by a hot, dry summer. Others are long and take time to develop over multiple seasons due to low amounts of rainfall accumulating.

The main types of drought, which may occur separately or together are:

• Agricultural drought – when there isn’t enough rainfall and moisture in soils to support crop production or farming practices such as spray irrigation.
• Environmental drought – when lack of rainfall has a detrimental impact on the environment and ecology.
• Water supply drought – when a lack of rainfall leads to concerns from water companies about supplies for their customers.

The Summer of 2022 saw a prolonged drought, which had a great impact on grass everywhere. 2026 was worse....

Grass is at least fairly tolerant of drought as it grows in a particular way which means it is often protected from threats such as drought and fire.

Other plants are perhaps less tolerant, and it was a struggle to keep some plants alive.
